Fungicides; add 'Kaligreen'
Beatles can be killed with Seven. The beatle problem is usually over by mid August - long before harvest for Cabernet Sauvignon and long past the pre harvest restrictions on its use - 7 days I believe.

Sulphur is good for Powdery but nothing else. It is also cheap. It will not control Downy, Black Rot or Phomopsis. JMS Stylette oil is also good for Powdery and may be preferable to Sulphur especially late in the season so as not to get a lot of sulphur in your wine. A 2.5 gallons jug of JMS will run you about $30 but will last you at least several years.

Mancozeb is a good preventative but there is a 66 day preharvest restriction on its use as well as product like it such as Penncozeb and Dithane. After June, you can use something like Ziram.

About two sprays each season with alternating sprays of Nova and Abound will take care of a lot of problems but Abound is VERY expensive but one gallon would last you a lifetime with only 10 vines. Use just prior to flowering, post flowering and fruit set and into June. Maybe you can get a small quantity from a commercial grower nearby.

Post verasion the disease pressure on the fruit diminishes greatly.

After verasion, you still need to be concerned with Botrytis. Products like Elevate are good for this and you can apply at verasion, about two weeks later and pre harvest.

I recommend you get the book "Midwest Small Fruit Pest Management Handbook" from Ohio State University Extension. It has everything you need to know. Their phone number is 614 292 1607.

I think you have a good choice with Cabernet Sauvignon. Some years may be difficult to rippen it fully but in general (my experience at least) it is more resistant to fungus and rot than varieties such as Merlot and Cabernet Franc. I have 12 three year old vines this year and they are in Excellent shape. They produce a lot of fruit and in future years I can see where I may have to cluster thin to avoid over cropping. I live in Central Maryland.

Good luck with your wine growing.

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
