Dry Beans

Postharvest Sanitation

(Reviewed 12/08, updated 12/08)

In this Guideline:

Field sanitation is important for reducing certain overwintering pests before the next growing season. Carry out sanitation practices in the field to reduce the spread of:

  • Weevils on blackeye beans. Eliminate potential sources of beans leftover in production areas such as:
    • in or on planting hoppers, or harvesters following harvest
    • broken sacks of seed beans
    • animal feed programs
    • fields after harvest
    • warehouse areas
  • Diseases. Plow under bean debris in fields infected with anthracnose (common, lima) or halo blight immediately after harvest. Bury plant refuse to reduce sources of southern blight.
  • Seedcorn maggots and weeds. Disc or plow early in the season incorporating residues from the previous crop and destroying weed growth.
  • Nematodes. Wash soil from equipment before moving from infested to noninfested fields.
