Beet Armyworm Control in Lettuce

Abstract

Success®, Proclaim®, and Confirm® treated lettuce exhibited no beet armyworm (BAW) larvae at 3 days after treatment (DAT). Avaunt®, Intrepid®, and S-1812 (Valent) treated lettuce had no medium-sized larvae but 0.3 to 0.5 small larvae were observed. At 7 and 10 DAT, BAW populations diminished significantly in all of the lettuce and no larvae or eggs were observed in any lettuce.
