Integrated Pest Management Options

Seed Treatment

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. Consult with your seed company and the Ontario Cereal Crops Committee Variety Trials at www.gocereals.ca for variety profiles. Plant into a well-prepared seedbed under good growing conditions. Use wheat in at least a 3 year rotation since the disease can survive in wheat residue. Avoid planting wheat after corn.
