Fungicide Resistance

During the past 3 growing seasons frogeye leaf spot in soybeans has been found to be resistant to Strobilurin.  Fungicide resistance is fairly common in fruit and vegetable crops.  This is why I worry aout blanket applications of fungicide when it is not needed.  We need to know if we have varieties that are fungi resistant.  Alternating modes of action and formulations can help over come reistand fungi as well.  This article from the University of Illinois has lots of good infor mation.
