Forbid 4F

  • Foliar Spray

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 and can 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.

Forbid™ is labeled for the following tree and shrub problems:

spider mites and eriophid mites

One 8-ounce container of Forbid™ 4F makes 200 gallons of finished solution.

For more information and a rate card, see the Forbid 4F Product Guide.
