The effective control of flag smut of wheat (Urocystis tritici) can be done by adopting of Use of resistant varieties, Seed treatment, and Crop rotation.
Strategies to prevent flag smut include the use of disease-resistant cultivars, chemical seed treatments, and crop rotation to reduce the amount of inocula present.
The spores germinate in dry soils, and maintaining wetter soils helps to diminish their viability. Carboxin is a commonly used fungicide on seeds, which works well to prevent onset of disease.
Application of systemic fungicides early in the growing season and at low doses is effective at controlling the disease.
