Hi all,
We have a veggie garden with eight raised beds (10' x 4' each), and also about 40-50 grape vines (Muscat and Riesling).
Veggies and Fruits include Tomatoes, cucumber, zucchini, beans, peppers, carrots, kale, tomatillo, lettuce, cabbage, brussels sprouts, herbs, strawberries, squash, potatoes. We also have some raspberry,blackberry, blueberry, and current bushes. Also an apple tree, 2 pear trees, 4 fig trees.
We can/preserve a lot of stuff, make salsas, sauces,and I make wine from the grapes.

We've tried to do organic the last few years but invariably end up with dead plants, most often due to powdery or downy mildew. This is mostly a problem on the grapes, tomatoes, zucchini, and cucumber.

So this year I was gifted some fungicide to help control this. I have some Kumulus DF, and Manzate Pro Stick. These are not generally available here (Ontario, Canada), just to farmers. So I have these huge 25Kg bags, which will last me decades.

I'm trying to find dilution rates for them for the small quantities I'd be using, maybe 2gallons to cover everything. So far the best I've found online is about 3/4 tsp of the Manzate, and 2-3Tbps of Kumulus, per gallon. The instructions are talking about Kg/acre.

Anyone else have any experience with these? They definetely do seem to be helping prevent the mildew. Normally by this time of the year we'd already have some visible but there is nothing.
