Grape vine leafs - Knowledgebase Question

Question by jsmplimit

I have a beautiful arbor 8'X10'with grape vines. The top has finally filled in to create a canopy feel. I have now noticed that the leaves are being eaten away by very small caterpillars or something like that and have used a few organic sprays and nothing has worked. Any suggestions???

You can usually treat with Bt (Dipel, Thuricide) to control caterpillars. If that is not working, you'll want to capture a few of the pests and take them to your cooperative extension office or well staffed nursery for identification. Once you know what you're dealing with, you'll be able to design a control strategy. Best wishes with your grapevines.
