Impact of Tarnished Plant Bugs on Cotton: Insecticide Efficacy and Varietal Response

J. T. Robbins, F. A. Harris and R. E. Furr


 
ABSTRACT

Tarnished plant bug adults and nymphs, Lygus lineolaris (Palisot de Beauvois), were effectively controlled with several foliar applied insecticides. Effective consistent control of both adults and nymphs was provided by application of Orthene® 90S (0.5 lb ai/A), Regent® 2.5EC(0.05 lb ai/A), and Monitor® 4L (0.33 lb ai/A). Bidrin® 41 WP (0.33 lb ai/a) and Vydate® 3.77 L (0.25 lb ai/A) provided effective control compared to the untreated checks. Calypso® 70 WG (0.047 lb ai/A) significantly reduced plant bug infestations and is one of the newer promising products tested. Certain adjuvants were tested and in some cases this use provided higher levels of control.
