As an insecticide, it is used to control numerous types of Scale to include that on oleanders, junipers, azaleas, camellias, magnolias, roses, and even San Jose and Obscure Scale on peaches, pears, plums, apples, citrus and pecan trees. Hi Yield Dormant Spray also controls mites, fruit tree leaf rollers, fall armyworms, whiteflies and pear Psylla. It is not recommended for houseplants.


Simply mix 3-ounces in 1-gallon of water and spray your trees thoroughly during the dormant season, repeating every 3 to 4 weeks, if necessary. Protecting your trees and shrubs when dormant will mean healthier plants during the active growing season.
