Troubadour® 2F is labeled for control of lepidopterous larvae, including a wide variety of worms and gypsy moths in plants which include grapes, fruiting vegetables, cotton, corn, soybeans, leafy green vegetables, caneberries and many other agricultural crops. It is a group 18 insecticide that contains the active ingredient methoxyfenozide in the diacylhydrazine class, which has a novel mode of action that mimics the action of the molting hormone of lepidopterous (moths, butterflies) larvae. Upon ingestion, larval stages of the order lepidoptera undergo an incomplete and developmentally lethal premature molt. This process interrupts and rapidly halts their feeding. Feeding typically ceases within hours of ingestion, although complete mortality of the larvae may take several days. Affected larvae often become lethargic and often develop discolored areas or bands between segments.
