I agree - I've used Mancozeb in the past with success. I prefer to apply liquid fungicides & insecticides. Who wants to rely on a customer to water? This year, I am putting granular down because I dont have an extra sprayer. I would have never thought to apply Mancozeb with a backpack. That stuff is so thick that I could see it clogging everything up. What is the shelf life of Mancozeb? I've bought some 2 1/2's that were 1/2 liquid & 1/2 solid rock at the bottom. What a waste.
