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.

Use the rate card to determine whether to use the high or low rate. For low rate applications mix .42 mL of product with one gallon of water, for high rate applications mix 1.2 mL in one gallon of water.

    I am looking to buy a 1oz or 4oz smaller sized container of Forbid like I did a year ago. I don’t need
    200 dollars woth for my small backyard infested with broad mites. Do you sell or know anyone who
    breaks down Forbid 4f or Spin. into smaler containers like I bought before. I found the site on line
    and can’t find the order in my email history. Any help would be appreciated. BTW, if you break it down,
    i do need to buy a professional sprayer too if it helps profits.

    • Mark,

      Unfortunately, I am not aware of Forbid or similar products in smaller sizes, except for the one ounce sample sizes. The only thing I can suggest for you is to contact Bayer directly and see if they have any 1oz samples you could purchase. We are actively pursuing providing our products in smaller sizes, but it is not a quick process. Stay tuned for updates to our product suite, and thanks for the suggestion on the sprayer. That is definitely on the list! Have a great day, and thank you for your interest.


    • There is no research on the safety of Forbid as of yet. However it is recommended to control spider mites on many websites. If you would like to take a look at the MSDS to make your own personal determination let me know and I can pass it along.

      Forbid does not control thrips. The following are the pests Forbid does control:

      Spider mites (including twospotted spider mite, southern red mite, maple spider mite, spruce spider mite, honeylocust spider mite, Euonymus mite, boxwood spider mite, tumid mite and Lewis mite), False spider mites,
      Rust and blister mites (family Eriophyidae), Tarsonemid mites (including broad mites and cyclamen mite), Whiteflies (Including silverleaf, greenhouse, and sweetpotato whitefly)
