ABSTRACT

Diamond™ (novaluron), an insect growth regulator, was evaluated for control of tarnished plant bugs (TPB) Lygus lineolaris and stink bugs (Pentatomidae) along with other cotton pests at a number of locations in the Mid-South states of Arkansas, Louisiana, and Mississippi in 2003. Rates of application for Diamond™ ranged from 0.039 to 0.078 lbs. a.i./A and the product was applied alone or in combination with Karate Z (lambda-cyhalothrin). Insecticides such as Bidrin (dicrotophos), Centric (thiamethoxam), and Baythroid (cyfluthrin) were used alone or in combinations as standards. Single or multiple insecticide applications were made depending on timing of TPB infestations and population pressure. Diamond™ provided TPB and stink bug control equal to or greater than the standards and other insecticide treatments depending on location.
