How can we control wheat disease?
- Disease can be controlled by planting resistant wheat varieties, planting disease-free seed and using a seed treatment prior to planting; disease may also be avoided by planting wheat early in the Fall and by shallow seeding.
- Follow crop rotation with non host crops for one year.
Which fungicide is best for wheat?
You should avoid applying the same active ingredient multiple times during the growing season to the same wheat field.
