North Central Illinois | Correct, I see very few rootworm issues with a diverse rotation. However, I know I'm occasionally playing with fire planting corn after soybeans at times. So far the variant rootworms haven't found me en masse. The only time I've seen severe rootworm damage is when I planted a small amount of corn following corn to get several small fields combined and in one crop. Even worse where I had planted squash though.
Do they have activity against seedcorn maggots? | |
