I've discovered black rot on my grapes, what do I do now? What is a good safe fungicide for just a couple of vines?


I battle it (and it IS a battle) with Mancozeb from

I'm also picking off the infected grapes. Those remaining are far enough along, that they'll soon be non-susceptible to the disease.

Lowe's has a spray available that may help. It is made by Spectracide and is called immunox fungicide active ingrediant is Myclobutanil use it at a rate of 2oz/gallon. I would also use in conjunction some captan. (fungicide for rose's) You have black rot now...you have it forever. Spray every two weeks next year starting before bud break. take two asprin call me in the morning.....
