Powdery mildew has historically been a minor problem here, but this year there 
was unacceptable levels of infection, particularly on Goldrush and in the Vf 
block where the spring sees a much reduced amount of fungicides. I am wondering 
about any control measures I could use this fall to reduce inoculum and also 
about integrating sulphur into the early season control program. I am 
uncomfortable in that I am using some of this high powered new chemistry for 
sooty blotch and fly speck control in the summer and worry about applying it to 
trees full of PM - it would seem a recipe for creating resistant strains.
