Miticide: for controlling spider mites and eriophid mites Foliar Spray Spiromesifen 45.2% Timing Applications can be made as soon as mites appear and prior to leaf damage or discoloration. Repeat applications as needed for control. Forbid 4F is a spray applied miticide designed to target all stages of the mite lifecycle, offering knockdown and residual control of spider and eriophyid mites. Mites are significant pests of shade trees and may cause disfiguring growths on trees as well as dramatically reduce the tree’s aesthetic value. Due to its mode of action, foliar-applied Forbid controls mites on the underside of leaves even if the product is only applied to the tops of leaves, while providing a long (45 day) residual.
