How to ID eutypa lata - dead arm

Now is the perfect time to be out in the vineyard looking for Eutypa symptoms. These here are normal, healthy Shiraz shoots, and have we got on the corner you can start to see there are some symptoms here, in these shoots. I've seen these stunted shoots with leaf cupping and you'll also see, from time to time, these necrotic lesions on the edge of the leaf and they can cup leaves. These are the classic symptoms of Eutypa infection in the vine.
