@WheatPete @kevinki16180099 @EmmaGraceEpp That did brighten my weekend! Just last week a retired colleague who has a small farm, who should know better, as he's heard my spiel, said he stopped growing wheat because soybean and corn pay more. I asked if he considered the impact of wheat on corn and soy -- "no". 🤷‍♂️

@mikevonmassow Congrats !

Fungicide is often considered after hail injury to corn due to the plant health statements present on many fungicide labels coupled with the natural desire to take action following a hailstorm.

An Overview of Hail Injury and Fungicide Use on Corn provides info to evaluate the potential benefits of fungicide application, and make the most profitable management decisions following hail injury in corn in upcoming growing seasons.

@KevinNixon_ @WheatPete Exactly. I'd take a false positive over a false negative anyday.

Looking to partner with industry for the 2027 @GrainFarmers #GrainsInnovationFund. I'm a @uofg researcher (Plant Ag) seeking a company using Ontario wheat, soy, corn, oats, or barley in a novel product. Faculty can't lead, so if you have ideas before Nov 6, DM me! #OntAg #AgInnovation #AgTech https://t.co/VhyJuQFJ0S

@WheatPete @badgerbean @WISoyCheckoff The proportion of N derived from BNF depends highly on soybean seed yield. High yields usually have a higher % of N derived from BNF (hence a possible N limitation, and the basis of applying N in high yield soybean). Is this the factor here Shawn?

@AdamJPfeffer @WheatPete Are they DeKalb? 😀

[Dave Hooker @cropdoc2]

@AdamJPfeffer @WxOntario1 Ill take it Tuesday. Slow going solo

Someone not having a good week. I think these are non-Enlist soys that were sprayed with Enlist a few days ago, before the operator found out. A lot of acres done in one pass around the outside of the field. UGH. @WheatPete @cowbrough @psikkema1

Excellent presentations by @Gur_sahib_singh and @AlbertTenuta this week at SW Crop Diagnostic Days @RidgetownCampus on pathology-related issues. "#BeautifulLesions" :) Cc: @wheatpete @ontag @GrainFarmers @OMAFAinnovates @plantagguelph @UofGuelphOAC

Many areas in SW Ontario could use a soaker. Photo: currently in my long-term tillage-rotation-N trial. Measuring tape goes down 50 cm in the wheat. Cc: @wheatpete

Would anyone in research have any leads on a used Lee Spider sprayer? USA friends? Cc: @Gur_sahib_singh

[Dave Hooker @cropdoc2]

Still looking for one

To whom it may concern: stop applying Jena experiment results to crop production.

-Farmers use managed, intelligent species selection; mixtures must beat the best monocultures, not the average of all monocultures as ecology measures it.
-Biodiversity benefits in ecological research take 3–5+ years to emerge in perennial systems; this tells us nothing about annual crops or cover crops.
-Ecological research finds that biodiversity correlates with benefits, not what causes them, and without knowing the mechanism, farmers have no basis for action.

@TerryDaynard @GlenneyAg Thanks for posting! The variability in P has been observed elsewhere as well, thus VR doesn't make much sense. You're correct. The K is more variable than expected; what does the relationship look like without the 2 "outliers"? @cropdetective
