    Theia has been a fantastic addition to my IPM program. Resistance management is something all growers think about daily - I am 80% organic and 20% conventional so we have plenty of experience with changing out our programs / using softer chemistries. That being said - I still have conventional acreage, and I still use conventional products there. Theia has shown to be just as great as a handful of the conventional chemistries we use on the farm. Theia has become a game changer for our fungicide program, bring our efficacy back up to a comfortable level. Powdery Mildew requires plenty of in season sprays - I highly recommend using Theia for at least a few of those in rotation.
