🚨Attention!!! Do you have black medic? My grad student Logan is looking for fields to visit this summer to collect roots for a project looking at black medic and pulse diseases. Please reach out if you're willing to have him visit your field in SK or AB!🚨

💧Testing your spray water source is crucial before use but lab results can be overwhelming.

This guide simplifies managing high salinity, pH imbalances, and other water quality issues.

@bdcryce12 @LowBoomLowDrift @breannetidemann @Plantmore1 @charlesmgeddes The interesting thing about mutations is that they are not caused by selection pressure. They are random, & most of them are unsuccessful, i.e., the organism dies. Successful mutations are very rare. That's one reason why evolution takes a long time.

[Breanne Tidemann @breannetidemann]

@Plantmore1 @nozzle_guy @LowBoomLowDrift @charlesmgeddes So IMO Tom is correct that when talking about mutations sublethal doses is less of a concern. However, there is growing concern about sub lethal doses increasing development of metabolic resistance. The other issue for me with sublethal doses is it means the plant doesnt die…

[Tom Wolf @nozzle_guy]

@AllamFarmer @LowBoomLowDrift For me, a low boom is 25". Any sprayer worth the money should be able to keep that height over a field plus minus 10" at ends. I know I'm dreaming. And I know the Horsch units can do better than most.

[Tom Wolf @nozzle_guy]

@AllamFarmer Omg, so true.

[Tom Wolf @nozzle_guy]

@LowBoomLowDrift @Plantmore1 @charlesmgeddes But better check with @charlesmgeddes or @breannetidemann for the real story.

[Tom Wolf @nozzle_guy]

@LowBoomLowDrift @Plantmore1 @charlesmgeddes 100% misconception. It is the use of herbicides per se that is responsible for resistance, not poor application. The idea may come from insecticides, where sublethal application allows stronger survivors to mate, sharing genetic material and increasing the offspring's tolerance.

[Tom Wolf @nozzle_guy]

@Plantmore1 @LowBoomLowDrift @charlesmgeddes ...of resistance, polygenic, that is the accum. of small tolerance over time. This occurs primarily in dioecious species (Palmer, Waterhemp), but also epigynous species like kochia. Better applic. can prevent this. But that is not why kocia is resistant to Grp 2, 4, 5, 9, 14.

[Tom Wolf @nozzle_guy]

@Plantmore1 @LowBoomLowDrift @charlesmgeddes Short answer is no. Site of action mutations confer very high levels of resistance, and they are amplified by selection pressure from herbicide application. The better the application, the stronger the pressure because this resistance is about 10 x. But there is another type ...

[Tom Wolf @nozzle_guy]

@JimPrat97487282 @LowBoomLowDrift For me the big wakeup was spring of '81 in RRV. Forced into fallow in the drought of '80, we saw spring wind erosion that filled the ditches on those pieces. Psychological nightmare. With just 5" of black stuff, we vowed never again.

[Tom Wolf @nozzle_guy]

@rvavs11 Every year that you can avoid a herbicide application on a field buys you time before resistance becomes problematic. In Australia, it got so bad that some resorted to deep plowing, inverting the seed-layer and starting over. Considering what happened this week, not that inviting

[Tom Wolf @nozzle_guy]

Mike, I know I'm being pretty hard on you for this. But it's wrong to think that using finer sprays will solve weed control problems. That approach instead creates more serious issues that affect agriculture as a whole.

[Mike Wasylyniuk @LowBoomLowDrift]

Ya. I was always of the same thinking before 10 inch spacing and reduced boom heights.

Then I started to notice over the years the kochia on headlands. Everyone reducing pressure to reduce drift with course droplets on headlands. Then baby kochia survives. How can you control drift with course droplets but also control baby kochia with the fine hairs that need fine droplets without using a residual ?

Ask this question often and no one has a great answer. Would you rather have drift control or perfect coverage ? It’s always a mix of both. Never perfect on either.

[Tom Wolf @nozzle_guy]

@rvavs11 I grew up in the age of herbicide euphoria, in the late 70s, 80s and believed in them completley. It's time to move on from that.

[Tom Wolf @nozzle_guy]

@JimPrat97487282 @LowBoomLowDrift I agree with you. All it takes is for one single weed to no longer respond to the herbicides available in your cropping system for you to need to use a non-herbicidal control. And what will that action be? Answering that is where my investment would go right now.

[Tom Wolf @nozzle_guy]

@JimPrat97487282 @LowBoomLowDrift I have not, but people are worried about that and looking for it. Herbicide resistance is documented on the https://t.co/cMOk6D9ftA database but the site is down, so I couldn't check.
