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
• 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
• 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
• 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.
