Free Shipping on All Orders

Forbid 4 F

The active ingredient in Forbid, spiromesifen, represents a new class of chemistry, called the tetramic acids. Due to its novel mode of action, foliar-applied Forbid offers growers an effective tool for management of mites resistant to conventional products.

Forbid features translaminar activity, controlling mites on both sides of leaves, and has activity from egg through adult life stages.

Forbid 4 F offers outstanding knockdown and residual control of mites and all stages of whiteflies for four to eight weeks. Thanks to its novel mode of action, foliar-applied Forbid 4 F offers growers an effective tool for management of mites resistant to conventional products.

General Information on Forbid 4F Miticide

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.

 

Forbid 4F's Active Ingredient: spiromesifin

Forbid 4F by Bayer contains spiromesifin as the active ingredient. Spiromesifin is a tetronic acid which blocks fat synthesis so the mites dry out and die. This mode of activity, inhibiting lipid biosynthesis thus causing dessication (i.e., drying-out), is virtually the same as that of soaps and oils. That is, the MOA for Forbid 4F can be considered, for the sake of simplicity, to be MOA 6 as defined in papers elsewhere on this website, and in articles appearing in the Rose Society’s newsletter, Basal Breaks. This is great because MOA 6 has little or no potential for the development of resistance – an analogy would be a flamethrower: you may miss some of your targets, but when they return they'’ll be no less vulnerable to the flame. 


Another feature of Forbid 4F is that  it is translaminar. The active ingredient, spiromesifin, while not systemic (i.e., it does not move through the plant’s vascular system like, for example, Merit does), is absorbed by the plant’s leaves and will move from the tops of the leaves to the bottoms where the mites feed. This ability to move from the tops to bottoms of leaves significantly reduces the tedium of the spray process – while care should still be taken to cover the entire bush, rigorous spraying of the undersides of leaves should not be required. Moreover, according to Bayer, Forbid 4F controls mites at all life stages and offers an excellent residual of four to eight weeks for mites.


How to Apply Forbid 4F

Apply dosage of Forbid™ 4F as needed for control by following the label instructions. Good coverage of the foliage is recommended. An adjuvant or surfactant may be helpful in improving coverage on hard to wet foliage to make the product stick better on plants.

 

For best results, the treatment should be made when the whitefly or mite population begins to build and before a damaging population becomes established. 

 

Forbid™ 4F is highly effective against the egg and nymphal stages of whiteflies and mites. For best results, applications should target the mites during these stages. For maximum efficacy against adult whiteflies, use the 4 fl oz rate of Forbid™ 4F. For heavy infestations, two applications may be necessary to control adult whiteflies.

 

Apply when pests first appear and prior to leaf damage or discoloration. Apply with ground application equipment in adequate water for uniform coverage.

 

Do not apply via chemigation. Do not apply Forbid™ 4F more than three times per season.
