Spray recommendation for grape problems?
I have a Mars grape vine and have never sprayed them or had problems with disease the past couple years, but this year has been rainy and humid and most of my clusters have at least a couple grapes infected some are mostly ruined. I removed some of the worst clusters and have been trying to pick off infected grapes, and have been spraying them with 1% neem oil, not sure if its helping. I think it is botrytis but im not completely sure, attached a pic. Anyone have any good recommendations for a spray that comes with a hand squeeze? Most were bulk for sprayers. Only one I saw at the garden center near my house today was Daconil, it didn't say anything about botryitis on the bottle so I didn't want to spend $10 if it wasn't going to work.
