Selected insecticides were evaluated in 1999 for efficacy against the tarnished plant bug in three studies. Traditional insecticides used for plant bug control such as Orthene (acephate), Bidrin (dicrotophos), and Vydate provided good control in late-season studies. Newer insecticides such as Steward (indoxacarb), Regent (fipronil), and Actara (thiamethaoxam) provided control of plant bugs equal to traditional insecticides.
