Crop Rotation

Rotation into non-legumes (cotton, corn, or other grasses) is absolutely essential to sustainable, long-term peanut production. Cylindrocladium blackrot (CBR) is increasing in S.C. and rotation is the most important factor in suppressing this and other diseases. An absolute minimum of 2 years (3 or 4 years better) out of legumes is recommended for sustainable peanut production. Soybeans should be avoided in a peanut rotation due to increased CBR and white mold problems. Tobacco rotations also increase white mold pressure.

Volunteer peanuts must be controlled in the following crop to prevent losing a year’s rotation. Peanuts are tough weeds and often require a two-step treatment program.
