Dave Nicolai: We welcome you today.

Dave Nicolai: To this installment of strategic farming field notes program. We are happy that you joined us for this session.

Dave Nicolai: These sessions on early season, we control today we're brought to you by generous support from the Minnesota soybean research and promotion Council.

Dave Nicolai: and also from the car growers research and promotion council for the state of Minnesota we welcome our guests, the program this morning.

Dave Nicolai: Dr Devlin Sarangi and Devlin he is our extension weeds specialist for corn and soybeans at the University of Minnesota located at St Paul.

Dave Nicolai: In northern Minnesota up and in the Bay area also with us as a co host Ryan Miller, out of the Rochester regional office and finally a Dr Jared Goplin.

Dave Nicolai: University of Minnesota he's a crops educator also and he's located out of the Morris regional office as well.

Dave Nicolai: Mr Miller you're on here with us any other general comments about the weather in your area in southeast Minnesota and in how the weed weed control processes looking.

Dave Nicolai: And will we have an opportunity for that this week, but I do understand that there's rain in the forecast for tonight Ryan.

Ryan P Miller: yeah that's right Dave I think you know the past week and a half or so that planting and spraying, and all that sort of progress has been fast and furious down here.

Ryan P Miller: A lot of progress has been made, I know a lot of people are prioritizing pre emergent server side so.

Ryan P Miller: You know, making sure they got their corn sprayed before they move into soybeans are working with someone else to get all that accomplished because.

Ryan P Miller: we've seen quite a bit of value in in those pre emergence and maybe I don't know Devlin if you wanted to kind of talk to that aspect first year.

Ryan P Miller: You know you did a lot of work, last year, there was a neat project, you had really, really made it visual the value of pre emergence herbicide when it comes to managing water hamp and some of that.

Debalin Sarangi: yeah so.

Debalin Sarangi: Good morning, everyone and.

Debalin Sarangi: Thank you Dave for the introduction and Ryan, for bringing this topic so yeah this year due to this good moisture situation in pretty much southern part of Minnesota and also some Northwest area, we saw that water him started coming up already and.

Debalin Sarangi: Some of the growers, I spoke with last week, they planted their corn the corn started coming up, but they are late in spring trees and that's something happened.

Debalin Sarangi: When you have wet spring, especially like you are really in rush to plant your crop and then your planner is way ahead of your sprayer and that happened with some of our growers and.

Debalin Sarangi: Definitely that's not a good idea, because preserve the foundations specially for the weeds like lambs quarters and water management.

Debalin Sarangi: So even if you are like one or two days left but still, we always recommend that follow your planter and spray your crops.

Debalin Sarangi: But still, like if your crop is, you must, there are some options still available that you can spray with the just.

Debalin Sarangi: emerged crops, but very limited options, but you can still spray some of them, because a residual control for water ham, especially water him and other weeds are very, very important, especially if you have to get season long control of your weeds.

Ryan P Miller: And so, so they do you have any practical recommendations, so you know the big thing is kind of knowing what weeds are going to come up and once they're up and.

Ryan P Miller: You know, maybe your your pre was an island time and so now you've got emerge weeds.

Ryan P Miller: you're dealing with different species different herbicide resistance is within those species, and so they can create and create a challenge as far as how do I get about go about managing emerged weeds, and so do you have any kind of recommendations there.

Debalin Sarangi: uh I mean.

Debalin Sarangi: Right now have to think about some of the herbicide I know, like some of the herbicide you cannot spray those are for sure, like valor type product that should go before your crop is immersed otherwise.

Debalin Sarangi: you'll hurt your crops, but.

Debalin Sarangi: And same thing with like verdict like soft fluffy innocent a product that will also barney a crop if you don't spray it ahead of your crop emerged So yes, I can remember some of the herbicide that should not be sprayed but.

Debalin Sarangi: Some of the herbicides that can still go, which is which you can use for your post herbicide, for example those grew 15 stuff that can still go, because they are recommended for post post emergence.

Debalin Sarangi: applications, and you can still spray them.

Debalin Sarangi: Like outlook are dual.

Ryan P Miller: So Devlin one thing that we did some applied sort of research and southern Minnesota south east and south central probably about seven or eight years ago now, was.

Ryan P Miller: Really kind of looking at this layered approach where we're using layered residuals, and so we did a whole bunch of different products and product combinations and rates and timings and.

Ryan P Miller: I guess the most critical component that came out of that in my mind, I mean there's some nuance with the different products and things but.

Ryan P Miller: The most critical component was kind of the timing, so that pre emergent at time of planting you got to have that down and then the second component, there is the layered residuals residual and the timing with that, and so I think through all that different work that was done.

Ryan P Miller: Timing that layer of residual between 20 and 30 days I know from the from the research work 30 days was like the optimal timing, but.

Ryan P Miller: You can't get everything done on day 30 so if we wait past day 30 that's too long, so once you're out in that 40 45 day window.

Ryan P Miller: That layer of residual search the it's like delaying your pre you know it's it's it's got to be earlier than 30 days so hitting that 20 to 30 day window seems to kind of be the.

Ryan P Miller: The sweet spot, so to speak, as far as adding in residual so that you're kind of preventing.

Ryan P Miller: Your weeds from emerging preventing the problems from there because we've got a lot of issues with different herbicide resistance is, and I know you're doing a lot of work like, with your graduate student now job that kind of figuring out how prolific some of these things are.

yeah.

Debalin Sarangi: yeah so that's a good point Ryan, so we always talk about lead ratio residual thing, but we have to remember those days dual herbicide.

Debalin Sarangi: They don't have any fully or activity so basically they prevent the weeds to emerge so when you are spraying your residual herbicide whether it is.

Debalin Sarangi: Your pre margins, or whether it is applying as positive margins, you have to make sure that.

Debalin Sarangi: Your weeds that are not up or even if there are not many of them, because the weeds which are up already, they will not be controlled with with your residual herbicide.

Debalin Sarangi: And that's why you mentioned about that period, when he should come back with your residual herbicide to get.

Debalin Sarangi: longer period of control, yes, that is important and another important thing that I want to mention to the folks like my student who is.

Debalin Sarangi: Testing some water and population for registrants he found that.

Debalin Sarangi: There is substantial number of fields infested with BP or registered water him, which is registered to like flexed or Cobra ultra pleasure so but.

Debalin Sarangi: The good news is when he spread those soil are the seeds as pre margins like with valor are subtle fantasy like when it was applied.

Debalin Sarangi: As pre merchants, the valor control those population totally hundred percent so that means the water and which is registered to flixster or Cobra now our ultra pleasure can be controlled using valor, which is also a PPO innovator, but applied on the soil as pretty much as herbicide.

Ryan P Miller: So so along those lines, whether programs or to the programs, I guess, I have i've been really interested in is the prefix.

Ryan P Miller: Which is a flex our dual kind of combination, as well as the word Altro we've had really good results and.

Ryan P Miller: It allows flexibility for folks not dealing with those ppl resistant water hams if I don't have quite the time to get on it right at planning, I can apply that early post.

Ryan P Miller: But then, you know be where this situation you're explaining is that it seems like that herbicide resistance becoming more prolific in the state.

Ryan P Miller: yep so those just kind of a couple of comments.

Ryan P Miller: So uh What about one question that came in Dublin was about Atrazine and metro abuse and those trains clearly mentioned using and soybeans and Atrazine can be using corn, did you want to make any comments related to.

Ryan P Miller: Those in their effectiveness, I guess.

Debalin Sarangi: yeah so last year was my first year at the university and you all know that last year was pretty dry year and we had severe drought pretty much all over Minnesota.

Debalin Sarangi: So, last year I cannot really like I really I was surprised that.

Debalin Sarangi: I mean it's not really surprising, but still I was surprised to hear like I got probably 90% cautions from different farmers and co operators regarding the carry over issues, and those are either actors in carry over are.

Debalin Sarangi: Some HPV carry over issues yeah so yesterday we I was chatting with Dr Tom Peters and we are discussing this question regarding accessing and met with us in and he mentioned that my thumb rule would be.

Debalin Sarangi: don't use them past June 15, because that will be kind of my tumble cut off, so that you can.

Debalin Sarangi: reduce some of those carry or thing to next season, because you never know how the fall and spring may look like, whether it is we will be wet spring are.

Debalin Sarangi: They will not be much, much and and you know, like if you are in a lower soil pH situation.

Debalin Sarangi: That may and bind this herbicide to the soil, but when you have high pH pockets in the soil, are in your field, you know those high pH will make these herbicide available.

Debalin Sarangi: to your subsequent crops, so that means your soybean and that will hurt your survey next season, so you depends on different factors definitely water is one of the factor temperature and my share and and also the soil pH So if you have some high pH pocket, be careful.

Debalin Sarangi: And look out for this carry over issues, and again I will emphasize on Dr Tom Peters comment that maybe it's not good idea when you pass June 15 using these episodes.

Ryan P Miller: So, in terms of week control, though let's look at metro abuse, and you know it's a component it's been.

Ryan P Miller: kind of generally along with one or two other active ingredients in a pre emergence program and allow those chemistry seem to do pretty darn good job.

Ryan P Miller: With pre merges we control, and so I don't know if you've got any comments there, but it seems by itself it's you know it's maybe not that impressive, but when it's in concert with other actives it seems to kind of round the program out.

Debalin Sarangi: yeah I mean I totally agree with you, I mean.

Debalin Sarangi: metric is, in itself, it was used long time in the US for weed control, but we saw in recent years, when you techniques with something else, like fears or some other product.

Debalin Sarangi: You will get better with control plus you are providing another additional sites of action which will reduce the chances for any resistance, and again I would emphasize my students project on water and screening he found that Atrazine and Atrazine registered is also.

Debalin Sarangi: There in Minnesota I mean he found about 20% population surviving Atrazine post emergence application, though, but still like.

Debalin Sarangi: That tries enraged and is there and it's a matter of time like when you get resistance towards metro region and other stuff So yes, I mean always tank mixing provides better weed control and provide additional sites of action for controlling these weeds.

Ryan P Miller: In the use rate is typically pretty low maybe eight ounces in those products, I think, generally, and so, then you're probably your risk of carry over kind of diminishes also with.

Debalin Sarangi: Especially like you're spraying as pre I mean you still have like long time you'll get rainfall and expected that you will get some moisture and that will kind of like diminishes the effort Okay, I mean the chances of carry over that's why I mean again I agree with Dr Tom Peters that.

Debalin Sarangi: If you spray something after June 15 there is a chance that it may carry over into your flixster I saw last year, like some of the folks applied flixster in July and.

Debalin Sarangi: Last year in the corn they saw some of the symptoms of flexor carry over so so anything applied before June 15 is kind of the tumble I agree.

Ryan P Miller: So kind of moving on to to Atrazine them and deal with that one.

Ryan P Miller: You know and se we deal with the cars geology so we've got a lot of sinkholes and there's some setback concerns that need to be followed with when they're using Atrazine and.

Ryan P Miller: You know I guess kind of my general opinion is when we when we use Atrazine it probably has its best bit when we apply it post emerge, and in particular kind of at that half pound rate.

Ryan P Miller: yeah with your group 27 so your HP PD inhibitors it seems to really kind of.

Ryan P Miller: get those going and activate and kind of see that synergy effect with Atrazine and it's I don't know if you agree with that or.

Ryan P Miller: it's kind of been my observation, then, then you use it a lot less in terms of pounds in whatnot and we're following some of those best practices, the recommended by the Department of Agriculture.

Debalin Sarangi: yeah definitely HP PD and Atrazine they have their.

Debalin Sarangi: synergistic impact and especially you'll see that when you apply pre actually like they're really.

Debalin Sarangi: show the synergistic impact, but but yeah I agree with you, but some of the folks have restrictions regarding Atrazine use due to some soil leaching and thing groundwater contamination stuff but.

Debalin Sarangi: But you have to think about like you have other choices to you can I would actually go in and use some of the other herbicides that.

Debalin Sarangi: So this year we're doing a project actually in corn, and we are literally avoiding Atrazine and use of any isotopes of Pluto, which is the balance stuff because.

Debalin Sarangi: We understand some of the growers might have limitations for using these herbicides and we are trying to.

Debalin Sarangi: get some good weed control without using these herbicides and and you still have some options pre and post choices that you can walk around and again, like, I want to.

Debalin Sarangi: I want to tell everybody that Atrazine is a good herbicide and it was there for a long time, and we are using it, and all good, but we also started seeing Atrazine register and.

Debalin Sarangi: Watch him population, and I think one of the population, my students cream, which was registered to Atrazine and HPV and that that is something concerning but the good news is.

Debalin Sarangi: When I was doing my Grad school in nebraska we had a field site which was bomber amaranth with which was registered to actress in and HP PD, but when they tank makes them and use them as pre margins.

Debalin Sarangi: That that provided really good control I think 85% control, but when they applied them like individually or sequence le they didn't control well so yeah.

Dave Nicolai: Okay, I think i'll switch over to a Jared gopalan if you can hear me on the on your line over there.

Dave Nicolai: You want to talk a little bit about from your perspective you're more on the Western side of the state, but what are we seeing right now in terms of weed high wheat emergence.

Dave Nicolai: That are were there and then also there's been some comments about you know difficulty in sourcing some of the group 15 herbicides if they're not on the shelf, I mean if we got a supply shortage.

Dave Nicolai: substituting some other things so let's just talk about those two issues here a little bit and then some more specifics on water him.

Jared J Goplen: You know they're getting big you know, there is some corn it's starting to pop out of the ground and the giant redwoods way ahead of that you know i've seen some ragweed now that's got to be six eight inches tall.

Jared J Goplen: You know, along some of those fence lines where there's really heavy population, so you know they're definitely going to be a problem.

Jared J Goplen: So, you know as we talked about or think about weed emergence timing and when these priests are going on.

Jared J Goplen: And the need for burn down applications, you know, especially if you're doing some type of minimum tillage or.

Jared J Goplen: or even some of these bigger weeds you know your tillage might not actually end up getting full control of those so it's something to keep an eye on so we don't know what those weed patches go to seed.

Jared J Goplen: So yeah things are definitely moving along in terms of availability, you know Tom indicated some shortage of dual Magnum.

Jared J Goplen: But I guess you know a lot of the other products from what i've heard have been been available but there may be some issues with related to whether or not the retailers have them.

Jared J Goplen: or not, but from what i've heard anybody who's kind of been on the ball and gotten things you know kind of ordered ahead of time should be just fine or have have the products in the shed already.

Dave Nicolai: So there's there's obviously other group 15th that you can substitute in there on on corn and beans if it's a metallic floors itself, we have a look, we have other.

Dave Nicolai: Opportunities so you know, along with that we've got some label changes here I guess you know thinking about early post emergence coming up here.

Dave Nicolai: we've got some restrictions on diet Canada in terms of south of I 94 and I believe that is what June 15 1212 June 12 and and so you got to keep that in mind with that.

Dave Nicolai: we're back on board with with unless dual across this across the state, after some theoretical changes that we're not you know enforced here so.

Dave Nicolai: The availability is for that as well, but keep in mind it's different on different sides of vine 94 under the north going later in the June, but we have the June 12 here in terms of that So if you don't get your poster merchants, you know other options on.

Dave Nicolai: and keep that in mind.

Debalin Sarangi: And then we have the temperature caught up this year too.

Dave Nicolai: Late right 85 degrees.

Dave Nicolai: On the maximum for application on on on that I can but I there was one question that came in lancer Jared I don't know if we.

Dave Nicolai: tom's not on right now, but actually was a fall application of a four year or valor, for you know, putting on the fall for a winner manuals and so forth.

Dave Nicolai: And it's for some places not my own Minnesota he was recommending you know he felt valor three ounces of.

Dave Nicolai: You know, add in the fall before TV before corn and soybean and actually even before I had a spring week was an option, I don't know over it for kosher control, and if you have any comments on that or none.

Jared J Goplen: August not really you know really targeting some of those.

Jared J Goplen: Those winter annuals as well as your coach of being a really early emerging weed you know, having something out there and available to control those and i'll kosher in some parts of the state, you know have significant resistance issues so.

Jared J Goplen: Any of those minimum till situations, you might not have very good post emergence options certainly makes sense.

Jared J Goplen: I guess, I do have a kind of a follow up to some of the conversation Dublin Ryan you're having about praise and things and it's related to early post applications and corn.

Jared J Goplen: You know more of the priests and corn allow you know a little bit later applications, and I was just curious you know this year versus last year, if you want to contrast that a little bit.

Jared J Goplen: You know regard last year we were really early this year we're really late, you know, is there any benefit, you know if we think about you know, having somebody early emerging weeds late emerging weeds.

Jared J Goplen: On doing an early post application or I guess i'm curious on what your kind of perspectives are there.

Jared J Goplen: With some of these these corn probably like triple flax for sure start those types of products, I guess, or or others that allow early post applications.

Ryan P Miller: yeah everything got so bunched up Jared that I think you know it's going to kind of happen all at the same time this year with with planting and pre emergent sprain it's kind of a.

Ryan P Miller: You know I don't know, I think.

Ryan P Miller: That, I guess, my main school thinking is always to prioritize your pre emergence application, particularly with corn I you know I know we've got some flexibility with the products to put them on early post, but if you get deleted all.

Ryan P Miller: You know, we know that corn just doesn't tolerate competition early season it it's you know doesn't have a lot of flexibility there and so to maximize.

Ryan P Miller: yield yield protection, you need to really prioritize and get them on but certainly a lot of the products do allow for that early really post application.

Ryan P Miller: And I guess I wouldn't be against it, if someone wanted to try it on a number of acres where they think they could get it done, and done in a timely fashion.

Ryan P Miller: It can it can work still, but I think there's a lot of risks to kind of go to that program in whole, particularly if you're trying to manage a lot of acres and getting the sprain done it's.

Ryan P Miller: there's not a lot of room for error there with weather changes and delays potential penalty even in terms of yield so.

Debalin Sarangi: yeah so this year I saw a couple of the situation so number one.

Debalin Sarangi: Some of the growers that deal their field, maybe two weeks back and then now they're trying to plant and all the weeds very much specially lambs quarters and ragged syrup and.

Debalin Sarangi: So if you spray your priests those weeds will not be killed, and then you have to think about.

Debalin Sarangi: Either burn down activities or another pass up till age or come back to it really early boss to margins, just to reduce the competition.

Debalin Sarangi: And second thing I explained today like planter is way ahead and then spread is coming late and we'd said emerging, so I saw these situations, this year, especially due to the wet spring in the southern part of Minnesota.

Debalin Sarangi: And I mean I can understand that that this year's planting got delayed and farmers would be really busy, and they may.

Debalin Sarangi: not be on time for early post you margins, but I think the early post emergence will be one of the important thing this year, especially when they're plenty of moisture and we'd started coming up and and I actually last week we.

Debalin Sarangi: Do one of our research site and we talked like will plant this last week sorry last week we killed one of our research side and we thought we'll plan this week and I went there yesterday, and I saw like it was all covered by graduates and.

Debalin Sarangi: lambs quarters just in a week so, so I think if you're doing a deal edge like your tillage equipment planter and spare should go together, I mean otherwise it's really difficult this year.

Dave Nicolai: I think that's an important point Devlin is because there's wireless warmed up and rapid emergence as Jared has indicated, so we got a lot of variability across the state of Minnesota small to.

Dave Nicolai: Larger situations, certainly if you're in a in a minimum tell or no tail it's a different situation, but the bottom line we're going to have rapid.

Dave Nicolai: We grow here I mean if you're if you have an ability to tell and some of these seedlings Jared Jared you know that might.

Dave Nicolai: Take some out by a little bit of time if you haven't gotten to the soybeans in terms of that, but I know there was one comment.

Dave Nicolai: That Tom had put in and actually came from Bob hearts for our former recently retired we'd scientists down in in iowa.

Dave Nicolai: And it's kind of a cadillac program on on the on the soybeans what are they looking at water hamp and those folks down there were using pre like with self interest zone or fears, you know, maybe followed up by.

Dave Nicolai: A group 15 you know that could be even a poster merchants apply without or pre to water him.

Dave Nicolai: And then coming back with a trait you know if you have a liberty been or a 240 and closer, but you know leverage those possibilities and I think that goes back to what Ryan, you were talking about before.

Dave Nicolai: In that situation is using those advantages of those traits but also incorporating that layered concept with some of the different things in there, particularly if you have a significant water him problem, and you know about it in advance.

Ryan P Miller: yeah and certainly for folks growing that they can be tolerant so you've been since early timing of the camera is going to be.

Ryan P Miller: Important and given the calendar date and the delay and planting you know I still think that the you know, certainly in certain parts of state that programs got a pretty decent fit and.

Ryan P Miller: The early applications tend to be you know less risky, I suppose, and and so those are.

Ryan P Miller: Those are things to think of if they've got that trade package in place, you know it's still got got some good utility early with the residual because we need to add that group 15 at that point to carry us through the season.

Dave Nicolai: I know we're jumping ahead here a little bit to post emergence Jared but any comment that you would have about.

Dave Nicolai: If things do get away from you on whether it's enlist or die kamba or liberty, as far as we'd size is concerned, now going going ahead here in there, so it's even beyond been the pre but there's a limit here.

Dave Nicolai: In terms of that so really the freezer important but maybe just want to review a little bit about you know smaller is better here.

Jared J Goplen: Now I don't know if there's much more to say, the smaller the better obviously you know under four inches in height is ideal.

Jared J Goplen: You know the one thing I guess i'll add you know and here's like this is the one thing that you can feel a little bit better about with blade planting.

Jared J Goplen: Is we do get quote unquote free we control out of our tillage you know, so you know by now, you know 60 70% of the giant ragweed probably emerged by now common ragweed would be similar.

Jared J Goplen: You know a good chunk of the lambs quarters is kind of made a start as well, so those early emerging leads, you know at the time of planting if we have spring tillage or burned down application.

Jared J Goplen: they're going to wipe out more of the weeds than they normally would with an earlier planning date so.

Jared J Goplen: You know I guess that's one thing that I guess you can feel a little bit better about you know with delayed planting you know it's always hard in springs like this, where you can't get in the field but.

Jared J Goplen: That is the one good thing you know at least when you're out there with the field cultivator or a burned down application those weeds that are emerged you're going to get better control out of those those pre plant things I guess compared to a normal year.

Dave Nicolai: Well, I know where our corn is spiking through here and Devlin your point earlier when we started the program about really read those labels.

Dave Nicolai: A lot of the praise you can go over the top, but you know some of these other ones are specific, you cannot apply them after the crop is emerged.

Dave Nicolai: So and it's going to happen pretty fast, so I guess the bottom line is go out and scout know what you've got on a field by field situation.

Dave Nicolai: But really read those make sure that that pre is not going to cause you a problem and in crop injury.

Dave Nicolai: as well, and the last comment I guess Ryan, we talked about it before we came on the air here a little bit reach back sometimes the concept.

Dave Nicolai: Some of the manufacturers gets over sold a little bit in terms of there's a limit on REACH back everything here to indicate after come in, it really completely aligned if that's going to really there is it's hard to count on it.

Ryan P Miller: And not not a terrible amount of consistency with the REACH back and concept to you know your stars have to align perfectly to to see that sort of thing happened and.

Ryan P Miller: The one of the comments I did want to make we were talking a little bit about weed size The other thing is coverage, so if you've got really dense weeds.

Ryan P Miller: Getting good coverage is absolutely critical so up in the gallon per acre or if you're allowed the flexibility to pick a different spray tip to give you better coverage.

Ryan P Miller: that's critical particularly it's true with all products, but particularly with the context, so the liberty herbicide program you definitely need a good coverage, which is.

Ryan P Miller: You know your weeds got to be two inches tall, ideally, and you need to get them all covered so.

Ryan P Miller: something to think about I know a lot of products are limited, on their tip choice and droplet size and are some of our newer products, I guess, and so something to be aware of if we're using those tips across everything it might not work equally well.

Dave Nicolai: Certainly, you know rainfall, is one of our best and carburetors to get things into soil solution.

Dave Nicolai: If we're, on the other side of this rain of comments I know there's always an opportunity Jared Rotary whole or to try to get things active a little bit about about that, but.

Dave Nicolai: Either way, I think we learned last year that even though we were in a dry situation.

Dave Nicolai: The a lot of those priests did pay benefits and we're still there in terms of residual so they're not going to go away right away, and you know there's still a worthwhile investment.

Dave Nicolai: In situations with that, even if you think the horses out of the barn, so to speak, in a dry spring we we still benefited.

Debalin Sarangi: So uh Dave just switching the gear quickly here, so we got a question about flame torch weeding thing and that's mostly came from a on an organic farmer, probably, so I I.

Debalin Sarangi: tried to look up and I found my 2014 slam reading workshop manual that I attended.

Debalin Sarangi: From Dr Steven as avec in nebraska so I just want to make some key points there because that person asked like what is the best timing.

Debalin Sarangi: And what is the best sequence so so flare moving is more like you're like non-selective barn down type treatment, just think about one herbicide that does the burn down treatment so.

Debalin Sarangi: This is like if you're so i'm just reading from that manual quickly so 10 to 12 gallons propane per acre if you are doing barn down.

Debalin Sarangi: thing and four to five gallons prop and if you are using banding like 12 inch breath banding for your flame reading.

Debalin Sarangi: And this is more like posts you margins flame routing so the weeds must be up and it must be less than three inches tall, so that you can kill it.

Debalin Sarangi: And if it is grass Unit two times, at least for killing the grass and sometimes you may need additional tillage for killing the grass, along with the flame reading thing.

Debalin Sarangi: And regarding some of the crop stages for for corn, if you do your flame reading before view on stage that should not be much easier penalty but up when you pass the view on stage whether it is V2 v3 V4 then either you have to be really careful that you are targeting the.

Debalin Sarangi: In between the rows area or you'll hit your corn, and there will be significant loss for serving up to calculate and stage Serbian is really registered to flame.

Debalin Sarangi: But once he passed the quarter lead in states like view on stage or something, then you will see the yield reduction, using the flame rating so Those are some of the key points I tried to look up that manual and found it.

Dave Nicolai: Okay, I think, thank you Devlin I think Ryan and Jared we've reached the end of our a lot of time here the the at the end of the webinar webinar survey.

Dave Nicolai: Before you leave there'll be a quick for question survey that will give us some feedback on the webinar and also suggestions for.

Dave Nicolai: Next week, and reminder next week session will be actually on Wednesday again may 25 at eight o'clock in the morning and then we'll be talking.

Dave Nicolai: crops in general development, maybe a little bit more about varieties and hybrids and so forth, if anybody did have to switch maturities as well as growth and development, and maybe we can call as well, but then again may 25 at eight o'clock.

Dave Nicolai: At the same time again we want to thank our sponsors the Minnesota so i've been researching promotion Council, along with the Minnesota corn and research and promotion Council as well, I want to thank Devlin and Jared and Ryan.
