Confirm (tebufenazide) and Intrepid (methoxyfenozide) provided effective control of yellowstriped armyworm (Spodoptera ornithogalli) and beet armyworm (Spodoptera exigua) in research trials conducted in the San Joaquin Valley, California during the 2000 season. Confirm (0.12 lb ai/a) and Intrepid (0.06 - 0.12 lb ai/a) reduced larvae counts and provided excellent cotton plant protection based on defoliation assessments. In direct comparisons, Confirm and Intrepid efficacy was superior to Dimilin, Asana and Success. Data is also presented to illustrate Confirm and Intrepid safety to key beneficial insects, an important component in an integrated pest management program.
