Disease Management

Prevention is the Goal
The goal of a disease management program is prevention and decisions concerning control measures should be made before planting or as early as possible. Waiting until the disease is readily noticeable invites an epidemic and complete crop disaster.

Disease Management Factors
• Crop rotation. Long rotations reduce soil-borne diseases and leaf spot. Rotate away from peanuts for at least three years.
• Correct identification. Learn to identify disease, know which diseases pose a threat and the conditions in which diseases will likely appear.
• Field mapping. Recording disease problems will help for the next time peanuts are planted in that field.
• Resistant varieties. Plant varieties resistant to diseases present.
• Timing of fungicide sprays. Use a calendar schedule or weather advisory to determine timing of the first spray and subsequent treatments. Protecting your crop before infection occurs is the goal.
• Equipment calibration and good canopy coverage are keys to a successful program. Improper calibration leads to poor coverage of fungicides, which is money wasted. Use a lower pressure to make sure fungicides cover the canopy. A single, flat-fan nozzle directly over the row works well.

An effective disease management program is vital to growing a high yielding, quality crop.
