| The brownish globs are fluids from inside the corn plant - a result of injury to the plant. I suspect that corn borers have damaged the plants. You may want to pull one of the plants and carefully inspect it by peeling away each leaf from the stalk. I think you'll find borers have invaded the stalk. Insecticides are not effective against these pests once they have entered the stalk. Wish I had better news for you! |
