ABSTRACT

Evaluations of new and existing insecticides for control of tarnished plant bug (TPB), Lygus lineolaris, in early-season and mid-to-late-season trials were conducted in 2003. In early-season trials, newer chemistries such as novaluron (Diamond) and thiamethoxam (Centric), and newly-formulated compounds such as imidacloprid (Trimax), provided adequate control of TPB, as did existing compounds such as acephate (Orthene), dicrotophos (Bidrin), and oxamyl (Vydate). In mid-to-late-season trials, new compounds provided enhanced control of TPB when tank mixed with pyrethroids and organophosphates. Experimental compounds, new chemistries such as acetamiprid (Intruder) and Centric, and existing chemistries such as Vydate provided adequate control of TPB. A pyrethroid alone performed poorly in early-season trials reaffirming that pyrethroids should not be used early season for control of TPB.
