Insecticidal efficacy against a complex of fall and beet armyworms and soybean looper in south carolina cotton

摘要

Field efficacy studies conducted on three grower farms indicated that the new insecticidal chemistries were more effective against beet armyworm (Spodoptera exigua), fall army worm (Spodoptera frugiperda), and soybean looper (Pseudoplusia includens), than currently labeled chemistries. Pirate~R (pyrrole), Tracer~R (spinosyn), Proclaim~R (avermectin) and Steward~R(oxadiazine) provided adequate control of these secondary pests; Larvin, Curacron, Lannate (carbamates) and Karate (pyrethroid)did not provide adequate control at standard usage rates.
