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 Trial
Results at www.gocereals.ca for variety profiles. Plant into a well-prepared
seed bed under good growing conditions. Use wheat in at least a
3-yr rotation since the disease can survive in wheat residue.
