Integrated Pest Management Options

Infected seed is lightweight and shrivelled. Fungicide seed treatment is very effective against this disease. Other options include the use of tolerant varieties and disease-free seed. Plant into a well-prepared seed bed under good growing conditions. Use wheat in at least a 3 year rotation since the disease can survive in wheat residue.

Seed Treatment

Comments (Days to harvest, label precautions, etc.)
For both commercial seed treatment plants and on-farm treatment using standard gravity flow- or mist-type seed treatment equipment. May also be used in treat-on-the-go seeder. Do not graze, feed green forage or cut for hay within 35 days of planting.

Comments (Days to harvest, label precautions, etc.)
Do not graze or feed livestock on treated areas for 4 weeks after planting.
