Severe weather event - protect your vines from Psa-V now

Due to the severe storm being experienced around the country, growers should be protecting their vines by applying a protective copper spray as soon as possible following the rain. Storm damage, including multiple leaf scars from leaves being stripped from vines, create Psa-V entry points.

Copper applications have shown to be the most effective control of Psa-V during the post-harvest and dormancy periods.

Follow label instructions and use winter rates.

Growers with high-risk blocks, including those showing Psa-V infection and young vines, may also consider antibacterial products.
