Tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), control with the experimental insecticides, Regent (class phenyl pyrazole) [2.5 EC 0.038-0.05 lb (AI)/acre] and Actara (class thiamethaozam) 25 WG [0.046-0.09 lb (AI)/acre] was as good or better than control obtained with Karate [0.028 lb (AI)/acre], Monitor [0.30 lb (AI)/acre], Vydate [0.25 lb (AI)/acre], and Baythroid [0.03 lb (AI)/acre] when evaluated in small plot and large plot Experimental Use Permit trials during 1997 and 1998. Harvested lint yields both years were slightly greater in the Regent [0.05 lb (AI)/acre] treatment than in the other treatments in both the small and large plot test trials. Actara and Regent both represent new classes of insecticides and will be useful in controlling tarnished plant bugs reducing insecticide resistance.
