Pests That Affect Sweet Corn
I want to plant sweet corn this summer for the first time. Before I purchase the seeds, please tell me what pests or diseases are prevalent in my area.

Diseases are not the main issue with sweet corn (although smut may occur). Insect pests are the big issue. The biggest problem is corn earworm; other pests include seed-corn maggot, cutworm, European corn borer, fall armyworm, flea beetle, Japanese beetle, spider mite, and stinkbug.
You will find individual profiles on each of these pests—including control options—in the Grow It Eat It section of our website: http://extension.umd.edu/growit/eco-smart-food-gardening/insect-pests-vegetable-garden.
