Eeek! We have almost made it to our first harvest of our tiny vineyard of 40 Merlot plants. The average brix is about 19. Yesterday we had rain and heavy wind all day. Today I went out to spray with Neem oil and I noticed about 10-15 split grapes on the ground and 3 huge, green, grasshopper type insects on my vines. They flew away when I swatted at them. Our vines are not netted, although we have nets and can do that. We have not seen birds around the vines. We do have pinwheels and reflective tape throughout the plants. What should I do to save my vines?
