IMPORTANT!  Avoiding Fungicide Resistance

Fungicides labeled for control of pecan scab differ in their chemical properties, their activity on the fungus, and the ease by which the pathogen can become resistant to them. It is important to understand this relationship so that the best fungicide choices can be made for control of scab. Some fungicides with excellent control properties against scab are also highly prone to resistance. There are three categories of fungicide resistance risk to pecan scab, which are outlined in Dr. Tom Isakeit's publication, Pecan Scab: Understanding Fungicide Activity to Prevent Fungicide Resistance.  The publication is available in our Library by clicking here.
