Nevada, Iowa | It looks like we are in for our worst infestation of Japanese beetles to date. This is a new experience for us in corn, I've had to spray beans a few times but not corn. Is there a threshold that those of you with experience like to use? I am just starting to see ear shoots and silks in the earliest stuff. No silk clipping yet but they are crowding the tassle at this point. I have read that they will devour the pollen, is there a number per tassle to go by? Thanks | |
