FORBID 4F Insecticide (Spiromesifen 45.2%) 8 oz.

Forbid 4F Ornamental Insecticide Miticide offers a unique mode of action that works against mites that have developed resistance to other more common miticides. Forbid 4F Ornamental Insecticide Miticide will control mites and whiteflies on foliage plants, ornamental plants, and flowers around commercial buildings and residential buildings, and in recreational areas like golf courses and parks. Controls pests for up to 45 days.

Forbid 4F Ornamental Insecticide Miticide is effective against all stages of insect development, but for an optimal outcome use this product at juvenile stages of development and prior to the development of a large population of pests. Spray Forbid 4F Ornamental Insecticide Miticide in a uniform manner covering the entire leaf structure. Avoid spraying to run off and use a spreader sticker if necessary.


FORBID 4F is a Flowable (Suspension Concentrate) formulation that is intended for control of mites and whiteflies on ornamental plants, flowers and foliage plants. The active ingredient contained in FORBID 4F is active on all mite development stages. However, mite juvenile stages are often more susceptible than adults. Application should be timed to coincide with early threshold levels in a developing mite population.

FORBID 4F is also highly effective against whitefly nymphs, plus it has a significant effect on the otherwise difficult to control pupal stage. For best results against whitefly, applications should target these life stages.

FORBID 4F can be applied by ground equipment. However, thorough coverage of all plant parts is required for optimum performance. Performance evaluations should be made 4 – 10 days after application.

Apply specific dosage of FORBID 4F as needed for control. For best results, uniform coverage of the upper and lower leaf surfaces is recommended. Avoid excess application that results in runoff from plant foliage. An adjuvant may be used to improve coverage on hard to wet foliage. For best results, the treatment should be made when whitefly or mite population begins to build and before a damaging population becomes established. Rate range is provided and is generally dependent on size of the plant and density of the foliage.
