Intrepid® (Methoxyfenozide) mimics the action of the ecdysone hormone, strongly binding to its receptor site in Lepidoptera species. This insecticide must be ingested by the target larvae and cessation of feeding begins within a few hours. Mortality occurs between 1-7 days, depending on species and growth stage. Intrepid® is not systemic, but exhibits limited translaminar movement. Intrepid® does not have vapor activity. It is highly effective against common cotton foliage feeders at rates that range from 0.05 to 0.15 pounds of active ingredient per acre (1 to 3 ounces of product per acre). Due to its specificity for Lepidoptera, Intrepid® does not cause mortality of beneficial arthropods, making it ideal for IPM programs.

In 2000 Intrepid® insecticide was granted a Section 18 and numerous demonstration trials were carried out throughout the Northwestern part of Texas and the Brazos Valley, corroborating the effectiveness of Intrepid for the control of beet armyworm and the cabbage looper.
