As a Dust:

Control of disease depends upon thorough and complete application (a thin, uniform film) to both tops and undersides of leaves. Small canisters may be used as a duster by partially crushing and rapidly squeezing the sides in upright position, or use a good pressure duster. Application when wind is very light or absent, usually early morning or evening, will prevent drift and loss of product to adjacent areas.

As a Spray:

(Using hand or tank sprayers) – Add proper amount of powder to small amount of water, strain, add remainder of water and spray – agitate sprayer to keep nozzle from plugging. Apply 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
