Protect yields with seed treatments.

Agronomy Bulletin 53 ─ Soybean Seed Treatments

Situation

Seed treatments can help protect soybean seeds and seedlings against a wide range of yield-threatening insects and diseases. Treatments can help to increase stand and vigor, promote earlier canopy closure and improve yield potential. The need for seed treatment depends on soil type, field history and pest pressure. Assess all factors before deciding whether to order seed treatment.

Factors to Consider

  • Field history
  • Planting date
  • Tillage
  • Pest pressure

Action Plan

  1. Factor in field history. If a field has a history of seedling diseases, there is a high risk of recurrence. Seed treatments can help bean seedlings get off to a healthy start. Insecticidal treatments can reduce the threat of damage in fields already infested with insects.
  2. Consider planting date. Early planting increases the possibility of achieving maximum yield but also can increase disease risk if soybeans are planted into cold, wet soils. Wet, poorly drained soils can cause the development of fungal pathogens that can lead to seed disease. Fungicidal seed treatments can ward off pythium and fusarium, which pose the greatest disease threat.
  3. Assess your tillage plan. Seedling disease risk is higher in no-till fields compared with conventional tillage. Many pathogens survive and reproduce on crop residue. Large amounts of residue also reduce soil temperature and increase soil moisture.
  4. Determine pest pressure. Bean leaf beetle, soybean aphid, white grub and wireworm are just a few examples of insects that can be controlled by seed treatments. Insecticidal treatments are especially beneficial early in the growing season. Insecticide treatments provide a larger window of time to scout for insect infestations. These treatments also may decrease the spread of insect-transmitted viruses.

Summary

Soybean seed treatments are becoming a routine practice in the seed industry. Consider field history as well as soil type and weather patterns that may affect the seed. Mycogen Seeds soybeans can be treated with CruiserMaxx® or ApronMaxx®. Consult your Mycogen Seeds commercial agronomist or trusted agronomic adviser to see which seed treatments are right for your operation.
