How a farmer controls corn rootworm in Indiana really...

How a farmer controls corn rootworm in Indiana really depends on what sort of pest pressure they face. In southern Indiana, most farmers wouldn't treat for it at all because there are very few corn rootworm larvae in that part of the state. In the moderate region in northeast and central Indiana, farmers may use soil insecticides or seed treatments for control. In the high pressure northwest corner of Indiana, most farmers use soil insecticides and some use seed treatments.
