Product Overview

OHP Fulcrum Insect Growth Regulator easily controls a wide range of nursery and greenhouse insects. It attacks viable eggs, nymphs, larvae, and pupae, disrupting the life cycle of insects and making it a highly effective solution to pests. Contains pyriproxyfen as its active ingredient which fights against hard to control insects on shrubs, ornamentals, flowering plants, and foliage plants.  It is proven to be gentle on plants and has a reliable translaminar activity for easy reaching of all surfaces of plants. This powerful insecticide and is recommended to be used rotationally with products from different chemical classes with various modes of action. For health safety, twelve hours restricted entry interval must be followed. Comes in a 32 oz. container.

DIRECTIONS FOR USE

It is a violation of Federal Law to use FULCRUM in a manner inconsistent with its labeling. Do not apply FULCRUM in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation.

CHEMIGATION

California Only: Do not apply FULCRUM through any type of irrigation system.

NOTE: If the user is not familiar with the application of FULCRUM through an irrigation system, apply to a small area with only a few plants to make sure a uniform and even application is being delivered.

Apply FULCRUM through overhead irrigation at rates stated in this label to provide proper coverage of all surfaces when treating for fungus gnats and shore flies. Overhead irrigation systems include overhead sprinklers such as impact or micro-sprinklers, mist-type irrigation such as fog systems and hand-held calibrated irrigation equipment such as hand-held wand with the injector. Do not apply FULCRUM through any other type of irrigation system. 

Plant injury or lack of effectiveness, or illegal pesticide residues in a crop, can result from the non-uniform distribution of treated water.

If you have questions about calibration, contact a State Extension Specialist, equipment manufacturer or other experts.

Operation Instructions: 

  1. The system must contain a functional check valve, vacuum relief valve, and low-pressure drain appropriately located on the irrigation pipeline to prevent water source contamination from backflow.
  2. The pesticide injection pipeline must contain a functional, automatic, quick closing check-valve to prevent the flow of fluid back toward the injection pump.
  3. . The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down.
  4. The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops.
  5. The irrigation line or water pump must include a functional pressure switch, which will stop the water pump motor 3 when the water pressure decreases to the point where pesticide distribution is adversely affected.
  6. Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump), effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock.
  7. Do not apply when wind speed favors drift beyond the area intended for treatment. Avoid spray overlap, as injury may result.

Prepare a minimum mixture of 1 gallon of water with the desired rate of FULCRUM and inject the mixture into the system. Injecting a larger volume of a more dilute mixture will usually provide a more accurate calibration of the metering equipment. Maintain sufficient agitation to keep the product in suspension. Meter into irrigation water during the beginning of the irrigation cycle. It is important to continue running the system after the application is finished to remove all product from the foliage and into areas where the immature insects are located.

RESISTANCE MANAGEMENT

For resistance management purposes, FULCRUM is a Group 7C insecticide. Any insect population may contain individuals naturally resistant to FULCRUM and other Group 7C insecticides. The resistant individuals dominate the insect population if these insecticides are used repeatedly. These resistant insects may not be controlled by FULCRUM or other Group 7C insecticides although local experts should be consulted for local resistance recommendations. The Group 7C classification scheme is based on the insect growth regulator (IGR) mode of action of pyriproxyfen. It is recognized that resistance of insects and mites to insecticides and acaricides can also result from enhanced metabolism, reduced penetration or behavioral changes that are not linked to any site of action classification but are specific for individual chemicals or chemical groupings. Despite this, alternation of compounds from different chemical classes remains a viable management technique. 

To delay insecticide resistance:

  • Avoid exclusive repeated use of insecticides from the same chemical subgroup.
  • Integrate other control methods (chemical, cultural, biological) into insect control programs.
  • Follow local, state, and Federal Integrated Pest Management (IPM) and Insecticide Resistance Management (IRM) recommendations.

For further information contact your local Pest Control Advisor (PCA).

PLANT TOLERANCE

A large number of existing ornamental varieties and cultivars coupled with the constant introduction of new varieties makes it impossible to field test FULCRUM in every location and under every condition where sold or in all of the combinations created by these differences. These differences include the soil or media type, pH, moisture or fertility, environmental conditions such as temperature, lighting or degree-days and horticultural practice and the manner of use and application of FULCRUM.

Make sure FULCRUM is compatible with the variety or cultivar under your specific conditions by testing it on a limited scale and observe for phytotoxicity for two weeks before making large-scale applications.

MIXING INSTRUCTIONS

Mix only enough spray mixture that is needed for the application. Clean spray equipment prior to using the product. Agitate mixture continually throughout mixing and application. Add in the following order:

  1. ½ to ?2; ½?3;? required amount of water
  2. Required amount of product
  3. Remainder of water

Ensure complete dispersion prior to application. Rinse spray equipment with clean water after each use.

COMPATIBILITY

FULCRUM can be used with most insecticides, fungicides and spray adjuvants. When tank mixed with FULCRUM, follow all precautions and restrictions on the label of the other product. When products are being used in a tank mixture for the first time, treat a small number of plants for 2 to 4 weeks and check for injury. If no injury is observed, proceed with planned applications.

LOW VOLUME SYSTEMS

FULCRUM has been shown to be effective for foliar applications when applied through Electrostatic Spraying Systems, PulsFog® Systems or other low volume systems. To calculate the amount of product to be applied, use the appropriate amount of product for the square footage to be treated with spray as listed. The amount of water is dependent on the amount needed for adequate coverage. Do not use low volume systems to control soil-inhabiting insects such as fungus gnats and shore flies
