From June 16th, 2013 - July 15th, 2013, we asked No-Till Farmer readers:
If you planted Bt corn hybrids this year, how much insecticide did you apply at planting time?
Here are the response tallies:
I only used soil insecticide on my refuge acreage (8%)
I applied a soil insecticide to some/all of my Bt corn acreage (30%)
I did not apply any soil insecticide (62%)
