On June 1^st 2001, Dow AgroSciences acquired the agricultural products of Rohm and Haas Company which included the new Lepidoptera active compound Intrepid*. Intrepid is a second generation MAC (molt accelerating compound). The MAC diacylhydrazine chemistry was discovered in 1983 and the mode of action was determined to mimic ecdysone and induce a lethal premature molt in some insects with Lepidoptera being by far the most sensitive. The MACs are the only insect growth regulators (IGRs) to mimic ecdysone. The MACs are not cross resistant with any other mode of action and are valuable tools for resistance management. They are faster acting than previous IGRs and halt feeding within hours. They have ovicidal activity on Lepidoptera eggs and are highly active on larvae. Larvae however must ingest the compound to be affected. They have broad-spectrum Lepidoptera activity with the best utility on armyworms and loopers. They are essentially non-active on insects other than Lepidoptera making them extremely valuable for IPM based programs and safety to pollinators. The MACs are classified as reduced risk by the EPA and were the 1998 winners of the Presidential Green Chemistry Award. In 2001 Intrepid received conditional registration on cotton. Currently, there are plant-back restrictions to crops other than cotton. Studies have been completed to remove the plant-back restrictions and review by the USEPA has been scheduled with action anticipated in May-June 2002. There are no anticipated supply problems and Dow AgroSciences will continue to support Confirm until all restrictions and supply issues are solved. A review of the recent performance with emphasis on armyworm and looper control will be provided. For the most recent labels and technical literature see www.dowagro.com.
