We do not consider variety to be a significant component of the decision to protect against Septoria diseases. Note that the harvest interval for mancozeb is 26 days, in other words, applications must cease if harvest is expected within 26 days.
Powdery mildew is also a serious threat in many fields.
The harvest interval for Bayleton is 35 days, which precludes application in the southern tier of counties. Leaf rust has been reported in three fields in Michigan. Susceptible varieties such as Lowell can still be damaged by this disease, but the light frequency suggests most fields will escape damage. Lodging has been reported, even in varieties that normally have excellent standability. I presume that this is due to the excessively wet soil conditions coupled with relatively severe weather.
