Hi lovetoplant. I make a 5 gal container of foliar spray that consists of 1:1 compost tea to rainwater, a splash of micronutrients (ferragrow 80 ml / 3 gal), about an ounce of fish emulsion, 3 ozs of kelp1 tbs pottasium bicarbonate...and most importantly, activated yeast. The yeast I am convinced has reduced all bacterial and fungal diseases to zero. None since I began using yeast! One other thing, as it gets into fall, I leave out the fish emulsion to reduce the n applied to my mangos. I also use a tbs of sticker to the brew.
