mould on my grapevines
Hi, I have two magnificent grape vines approx 10 years old. Prolific fruiters, Last year the larger Merlot developed grey mould on the leaves which spread to the fruit, destroying all grapes. This year it had spread to the second vine 10ft away and both vines were diseased badly. Searching for a solution has been frustrating. Any pestiside that would help is not available to amateur gardeners. Please can someone help me to save these two lovely vines?
