| In my area (ECIL) it seems fungicide/insecticide use is going into the 'nobrainer' camp on beans and maybe backing off a little on the corn. I've done a little on corn for the last 2 years with some good response - could be up to 20bpa, but I'm not sure it was the only factor. Guys around me did some trials and the average was a 6 bpa increase in beans. I've been applying some insecticide most years to beans if there is even a hint of aphids. The numbers might be a little bigger than what would be a long term average, but it does suggest the effect is significant and pays.
As I post this I'm debating on prepaying for fungicides/insecticides for both soybeans and corn (stratego 12oz corn, 10oz beans + insecticide - sprayed myself). I'm wondering if the insecticide is doing most of the work with the fungicide providing more of a synergistic effect. I didn't see much yield gain with fungi's only in the past. Where do the fungi application rates really need to be? From some of my conversations on fungicides it seems that it's entirely clear what they do or how they effect the plant. I've been to the meetings and understand what's supposed to happen, but it seems the plant health effects might be more complex than just keeping a few fungus spores out.
What are you guys planning on for fungicide/insecticides?
Thanks,
