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 too wet,
5. removing excessive water through increased tile drainage and minimizing compaction and,
6. applying seed treatments that protect the plant during germination and early growth.

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), previous page, for more details.

Comments
One application as a seed treatment. For additional disease control, use in combination with Apron Maxx RFC or Cruiser Maxx Beans.

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.

Comments
For commercial and on-farm application. Compatible with Rhizobium-based inoculants. Check with inoculant manufacturers for details prior to use. Do not graze or feed livestock on treated areas for 45 Dynasty 100FS per 100 kg seed.

Comments
For commercial application only. Compatible with Rhizobium-based inoculants. Check with inoculant manufacturers for details prior to use. Do not graze or feed livestock on treated areas for 45 days after planting. For anthracnose control, tank-mix with 10 mL of Dynasty 100FS per 100 kg of seed.
