Pesticide Usage 
Since corn and alfalfa hay are the predominant crops in the area, pesticide 
usage concentrates on pests which afflict these two crops. The major 
insect problems are the corn rootworm and the corn borer. Farmers 
primarily use Counter, Dyfonate, Furadan, Lannate, Diazinon and Sevin to 
control these pests. For weed control, Atrazine, Bladex, Dual, Simazine 
Lasso and Metribuzin are the major pesticides used.
