Fungicide seed treatments for wheat
Some seed treatments also offer limited control of fall-season foliar diseases. Tebuconazole and difenoconazole provide some protection against fall infections of powdery mildew, leaf rust, and Stagonospora nodorum leaf blotch. A seed treatment will not prevent the disease from becoming reestablished in the spring.
Triadimenol, tebuconazole, and imazalil can shorten the coleoptile, so avoid deep planting with these treatments.
Producers must balance the possible benefits against the cost and the possibility of having leftover treated seed. Leftover treated seed can be avoided by using hopper box treatments. If seed is treated on-farm, pay close attention to thorough coverage of the seed.
