Iowa | So have we reached a consensus on a threshold to spray these buggers. They always seem somewhat variety specific, and usually the worse they are the poorer that hybrid yields. However ive done some fungicide with bifenthrin in before and it never really seems to kill them. Thinking lorsban would be the only trick,but never really heard a solid answer on spraying them. Application is 13- so I'd need 5bpa to pay for it, if price doesn't improve its crop insurance bailout. Farm their on is one that if we don't get 2 inches of rain to finish it won't matter. | |
