I planted 10 Cabernet Sauvignon vines this year (in SE Pennsylvania).
They've been growing very well until the Japenese beatles discovered
them in the last week or so. I also need to start spraying for powdery
mildew but I'm not sure which product is best. Sulpher? Is
lime-sulpher typically used? What about Mancozeb?

Any help is appreciated.

Thanks,
RD
