I have one very small plot that has been wiped out already. I've planted brassicas in that spot for the last 4-5 years, and they rarely let it get much above 4 inches or so. Never understood that. Its in a clearcut with plenty of food, but they like it for some reason.
I suspect the plot above will get hammered come mid October? It had soybeans in it this summer but they got totally wiped out, not even a stem left.
The pic with the guys boot in it was a Roundup Ready soybean plot that we sprayed with Roundup the other week and just brodacast brassica in to it. The soybeans that were left have since been browsed off.
