CORN Use varieties resistant or have tolerance to the Gray Leaf spot disease. Melvin A. Newman, Professor Entomology and Plant Pathology Suggestions to Help Corn Growers Survive in 2001 Have a whole farm analysis made of each farm to be planted by a University of Tennessee Farm Management Specialist early in 2001. Also if European corn borer or Southwestern corn borer was a problem last year in the field to be planted, select a high yielding Bt variety that has resistance to both corn borers.
Soil test each field to be planted to corn.
Fields with a water pH of 5.7 and above do not lime. Fields with a water pH below 5.7 lime according to soil test. Apply nitrogen at a rate of 1 pound for each expected bushel of corn yield. Be realistic on expected yield for each field. Do not apply excess nitrogen in hopes of pushing a soil that has no history of high yields.
