ferti·lome® Tree & Shrub Drench Concentrate is a powerful insecticide formulated with Imidacloprid 1.47% to control a wide range of insect pests in trees and shrubs. It effectively targets and eliminates pests such as aphids, billbugs, crane fly larvae, leafhoppers, leafminers, borers (round headed, flatheaded, and long horned), pine tip moth larvae, royal palm bugs, scale, psyllids, and more. The insecticide is easy to use and dissolves in water, allowing it to move down through the soil and be absorbed by the roots. Once absorbed, it travels up through the entire plant system, providing year-long protection, even into new growth. To apply, dilute the concentrate according to the specified rates: for trees, use 1 oz. per one inch of distance around the trunk per gallon of water, and for shrubs, use 3 oz. per foot of height per gallon of water.
