What you see here is Grape Gall made by Phylloxera. A pest of Eurpean Grape vines expecialy here in the North East of America. Basically these little guys live in the bark and roots all winter and when the folliage starts to come out they awaken and this is what can be found.
This is what Gall looks like on a leaf. It goes thru both sides. Kinda funny looking but not good for the Grape vine.
This is actually a Gall that was formed over a Grape bunch. If left on the vine it will essensially kill it. The fruit will not get the chance to come to it's full potential. Unfortunatly the only thing to do is to cut off the infected sections and clean up the vine as best as possible. Be sure to prune after the harvest is over to prevent reinfestation.
Being a curious bunch we before we even knew what it was we cut off a small branch with a Gall on it and cut it open. This picture here is what we found and thankfully it helped us find out what it was that infested the poor grape vine. This little red-orange worm is just a baby and if we hadn't found it, it would have grown to infest the rest of the vine. An interesting fact was that American hybrids like out Concord is resistant to this pest. So it only seems to be effecting the old vine....guess we know it is not and American hybrid one.
