Sorghum Seed Treatments


Pioneer Premium Seed Treatment - Grain Sorghum

The 2012 grain sorghum offering includes a package of fungicide and insecticide providing excellent protection and control against a broad spectrum of early-season seed and soilborne diseases, and protection from insects.

Choosing Fungicide (FST) + Insecticide (IST) Seed Treatment to help maximize yield

  • FST (fungicide): Triple mode of action FST protects seed and seedlings from seed-and soil-borne pathogens such as Fusarium and Pythium.
  • IST (insecticide): Systemic protection from seed and seedling damage such as chinch bugs and aphids.
  • New for 2012: Triple mode of action fungicide alleviates additional plant stress a fungicide-only package cannot

thiamethoxam Systemic protection from seed and seedling damage caused by chinch bugs, greenbugs, yellow sugarcane aphid, corn leaf aphid, wireworm, seedcorn maggot, and fire ants

Triple mode of action fungicide plus powerful insecticide package
broadens range of protection.

Chart: Sorghum seed treatment trial yield comparisons - standard vs. triple mode of action

Triple mode of action treatment outperformed standard fungicide treatment
by 2 bu/acre at 21 locations where sorghum downy mildew was present.*

*Some fungicides are applied to the seed at a higher rate in sorghum downy mildew areas per label recommendations.
