ABSTRACT

During the 2001 and 2002 growing seasons four small plot efficacy trials were conducted to evaluate control of heavy, mid to late-season infestations of tarnished plant bugs (TPB). Orthene (acephate), Bidrin (dicrotophos) and Centric (thiamethoxam) were the most consistently effective treatments. However, products such as Vydate (oxamyl), Trimax (imidacloprid), Intruder (acetamiprid), and some of the pyrethroids also provided significant control. Results of these trials indicate that two successive treatments are often required to obtain effective control of heavy, mid to late-season infestations of TPB nymphs.
