Integrated Pest Management Options

This disease can occur on all soil types but losses are greatest on wet, clay soils. Minimize soil compaction and remove excess moisture through increased drainage. Treat seed with metalaxyl or metalaxyl-M and plant into warm soils (16°C or 60°F). Rotate 3-4 years between bean crops.

Due to the threat of anthracnose infection to this crop, ALL edible bean seed should be treated with DCT or Dynasty 100FS. See ANTHRACNOSE (Colletotrichum lindemuthianum), on page 89, for more details.
