Hi,

Found this....

Surround
Spray Rates

Label instructions recommend a rate of 25# of Surround per acre per application. Whether you mix this in 50 gallons of water or a 100 gallons of water is determined by sprayer type and the size of the trees on your acre. Coverage needs to be applied to the point of runoff and allowed to dry. A sticker-spreader isn't necessary, and in fact, experiments with vegetable oils to improve kaolin's holding power have decreased efficacy. The coverage provided by a hand-held wand spray rig is often superior to an air-blast sprayer simply because you take more time per tree to achieve a full coat. Home orchardists with a backpack sprayer can figure on using 1/2# per gallon of water (note that a diaphragm-type pump will last longer with a wettable powder like Surround), gauging the coverage more by point of run-off than by a hypothetical amount per acre. Surround stirs best into the water as opposed to pouring water into the dry powder.
