Now that we are full into spray season, I wondered how many farmers are running into glyphosate inversion drift or even worse the round up extend used on soybeans.
Any major spray drift stories or wrong fields sprayed with wrong chemical. Yes, the exciting job of spraying!
Also , any hints on better brand nozzles and methods of spraying in breezy conditions.
Two years ago , I had half a quarter turn brown from dicamba drift. Spray moved 1 mile. Lost 15 bushels an acre of beans on that 80 acre area. Last year lost 50 acres due to same problem. This year I grew all dicamba beans to reduce that problem. I know i should not have to change my varieties due to some bodies else mistakes.
For the american farmers has that problem gotten better or worse.

I'm surprised blanket Dicamba on tolerant crops hasn't been banned yet. What a nightmare. For guys down in Texas it is much worse than losing some soybeans. It's affecting other crops like cotton, orchards, vineyards, etc. Apparently dicamba drift isn't a major problem in Canada: www.producer.com/news/dicamba-drift-not-a-major-problem-in-canada/. Your experience shows otherwise! I guess here in Canada we don't have as many crops that are so sensitive to it other than non-tolerant soybeans. |

I find liberty drifts real bad, been adding valid, Loveland product. And it seams to be helping. I don’t find that Rup drifts real bad ? No beans in this area so don’t have dicamba problems.

Xtend is a terrible product. Vapor grip my ass. I grow Enlist beans and get to look at cupped leaves most of late June and early July.

The problem with Dicamba is that it can sublimate. You can spray it in perfect conditions and if conditions change, it can revert back from the dried solid on the leaf to a gas, lift and move to another field THE NEXT DAY!. Perhaps Texas has more conducive weather patterns for this sublimation to take place than we have in Canada.

My theory on why Canada doesn't have too much of an issue with dicamba is for the most part we don't get that sharp rise in temperature compared to the south area. Exact opposite of an ice cube evaporating in the freezer. Regardless I hate spraying it for so many reasons.

We've got so much of the crap floating around in the atmosphere here it can't be good for anything, humans included. |

Two days for sure. |

This dam! Wind can F right off. Have to spray liberty and this wind is a little high for it. 25-40km how high of wind would you guys go?

I think the cutoff is July 1. Vapor grip my ass. |

Why anyone would spray something that is potentially volatile days after application and why insurance companies would cover such a thing is lost on me. It is virtually impossible to ensure a safe application. Funny thing is, back when I was on the other side of the desk (30 years ago), I sold LOTS of banvel and never heard of the kind of problems we are seeing today. Something has changed.

I agree LTK. Xtend should not have a label. I think the old banvel days maybe it was sprayed earlier in better conditions with less likely inversions...? I don't know but it sucks for us non xtend bean guys that realistically have no recourse when our crop gets dinged because there is no way to prove it's origin. Kind of by design I'd say.

Depending on what's down wind, I have no problem spraying Liberty in 25-40 kph winds, depending on the strengths of the gusts. Steady wind is much easier to deal with, even 30+ kph. Use high water rate (at least 15 gpa), lower the pressure, keep you booms low. Nice thing about Liberty is it drift won't kill established grass and trees on the borders. Just burns the leaves a little.
What nozzles are you using?

Just burns the leaves a little. What nozzles are you using? I agree except about water volume. Spraying in the wind always gets better results especially with a contact product as the weeds are twisting and turning in the wind and the spray gets all over them not just on the top. However, I don't subscribe to the more water volume = less drift line of thought. In fact, IMO it is the exact opposite. More water volume = more drift all other things being equal. The i am spraying a 10GPA product I will spray in about 10KPH less wind than I will at 5GPA. I would think this would be even more evident with PWM but don't know that for sure. Example, a nozzle that produces 10% driftable fines @ 40PSI will produce twice as many driftable fines at 10GPA as it will at 5GPA when sprayed @ 40 PSI at both rates. If you drop your pressure to reduce the drift able fines at the higher water volumes, you can drop your pressure at the lower eater volumes as well thus reducing the fines by the same %. Lower pressure and keep booms low to reduce drift for sure but in my experience, lower water volume = lower drift. |

I’m using TT White 08. 13.2 USG. With aim command. I typically spray at 28” high. Is that too high? Or should I go 20” high. I was told with aim I should be at least 30”. I find its too high.
