Yeah I have some nongmo beans that are pretty clean also, a few random velvet leaf that I have been trying to pull when I see them. I have 5 different residuals on those acres. Not enough rain to activate the prefix post applied.
Just had some random thoughts today while it was raining, I didn't realize the mechanics of how the herbicides work. Alot of the post applied programs didn't activate here. The PPI programs have done well.
Any guesses on how many years velvet leaf can survive in the soil?
There's university data indicating 1% still viable after 75 years
I have plowed pasture/hay that hadn't set any new velvet leaf seed for 20 years and still have plenty emerge. |
