This past week was one of angst for soybean growers. On one hand the soybean market was responding nicely to a weather scare in the US. On the other hand soybean aphid numbers were exploding and eliminating some of those same high priced bushels. By Monday afternoon, Brian and I made the executive decision to stop spraying. If anyone asked, the bean crop was too far advanced and it was becoming revenge spraying. This sort of worked until today when a couple of nervous growers wanted two fields sprayed and Russ wandered across an IMPACT plot where the full season varieties were under heavy pressure and not close enough to the critical R6 stage of development. The R6 stage is when it no longer is worth killing aphids, however a lot of brain cells were being burned last week while trying to determine how close we were to R6 vs aphid numbers. No one was satisfied, which was the reason for the stop work order on Monday. The grower, the agronomist and the custom applicator were all getting grumpy.
The best description of soybean development I have ever seen is courtesy of Shawn Casteel, Purdue Extension. Definitely worth a look and saving for future reference.
I always marvel at how a corn plant can pee on itself. We had 2 mm of rain on Tuesday night which is the first measurable precipitation in 3 weeks.
You sometimes hear agronomists preaching tip fill on corn. I took some pictures today in my hybrid test plot.
Leave it to Nuhn Industries. I attended the North American Manure Expo last week which was held at the University of Guelph Arkell Research Station. On display was Nuhn's latest invention, called the Lagoon Crawler.
