If applying as a spray and not a dust, what is the application rate of Bonide Copper Fungicide per gallon of water for grapes?


Bonide Copper Fungicide can be used as a dust application or liquid spray application. Refer to page 3 of the product label for information on both types of application. For grapes, the mix rate is 2 – 26 oz. If applying as a spray mixed with water, you will add the proper amount of powder to small amount of water, strain, add remainder of water and spray – agitate sprayer to keep nozzle from plugging. The product label states to use 3 gallons of mixed solution to a small tree or bush, 6 gallons of mixed solution to a medium size tree, or 9 gallons of mixed solution to a large tree. Thoroughly spray upper and lower surfaces of foliage to the point of runoff. Do not overspray.
