Integrated Pest Management Options

Problem when conditions are cool and wet during planting or when these conditions result in a delay in seedling emergence or developement. Mid- to- late-season moisture stress (dry conditions) can increase the disease.

Management practices include:

1. selecting varieties with good general tolerance to root rots,
2. promoting root growth through a good fertility program,
3. rotating crop (3 years between bean crops),
4. not overworking the soil and avoiding working it when it is to wet,
5. removing excessive water through increased tile grainage and minimizing compaction and,
6. applying seed treatments that protect the plant during germination and early growth.

Due to anthracnose concerns, all seeds should be treated with DCT. See the section Anthracanose (Colletotrichum lindemuthianum), for more details.

Comments
Ensure good seed coverage.

Comments
For both commercial seed treatment plants and on-farm treatment using standard gravity or mist-type seed treatment equipment. Compatible with Rhizobium-based inoculants. Check with inoculant manufacturers prior to use. Ensure uniform coverage.
