Capture Performance on Key Cotton Pest

H. R. Mitchell and L. D. Hatfield


 
ABSTRACT

Capture® 2EC (bifenthrin) was evaluated in field efficacy trials for early season insect control, impact on predatory arthropods, pest flaring and subsequent yield when applied early season. Early season applications included a pinhead square application followed by a second application made at state recommended threshold levels of tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), or cotton fleahopper, Pseudatomoscelis seriatus (Reuter). Various insecticide treatments included Capture 2 EC at 0.05 lb ai/A, Karate Z at 0.028 lb ai/A, Baythroid 2 EC at 0.03 lb ai/A, Orthene 90 SP at 0.5 lb ai/A, Vydate 3.77 L at 0.25 lb ai/A and Provado 1.6 F at 0.047 lb ai/A. Capture provided tarnished plant bug and cotton fleahopper control superior to and resulted in negative impact on predator arthropods similar to that of the other insecticides evaluated. Predatory arthropod populations required approximately 10-14 days to rebound to that of the untreated check. Capture provided aphid suppression that minimized aphid flaring observed with Karate, Baythroid, Orthene and Vydate. Capture provided control of subsequent Heliothine infestations equal to that of Karate and Baythroid and superior to that of Orthene, Vydate and Provado. Positive yield response with early season applications was observed with yields generally higher with Capture and Provado than Karate, Baythroid, Orthene and Vydate.
