AGRICULTURAL chemicals manufacturer Rohm and Haas Company has received registration from the U.S. Environmental Protection Agency (EPA) for use of Intrepid 2F insecticide on cotton and pome fruit.

Intrepid (common name methoxyfenozide) is a new insecticide that imitates the natural insect molting hormone, 20-hydroxyecdysone. It induces a premature, lethal molt in target larvae within hours of ingestion of treated plant tissue. High among its benefits, it is active only on lepidoptera.

Intrepid is a second-generation molt-accelerating compound (MAC). A first-generation insecticide in the same family, Confirm insecticide, has been used by cotton and apple growers for several years. Intrepid provides broader spectrum control than Confirm on these crops.

The EPA has classified Intrepid insecticide as a reduced risk pesticide for the registrations in cotton and pome fruit. Intrepid insecticide poses minimal risk to human health and to the environment Characteristics include:

  • Effective control of several resistant insect species, including cotton bollworm, tobacco budworm, soybean looper, and armyworms, which will make it a useful tool for resistance management.

  • Active only on lepidoptera, not active on beneficial insects or other arthropods. It does not harm honeybees, or predatory mites, wasps, spiders, lacewings and beetles that naturally control other insect pests.

  • Low mammalian toxicity.

  • Low environmental impact.

  • Negligible occupational risk.

  • Odorless formulation.
