Mortality of Southern green stink bug, Nezara viridula (L.) was investigated in a spray table. In one study, dicrotophos was compared with acetamiprid, imidacloprid and thiamethoxam. In another study, dicrotophos was compared with bifenthrin, cyhalothrin and zeta-cypermethrin. Insecticides were mixed at 2 and 5 gallons/acre and several active ingredient rates were compared with an untreated check. Dicrotophos produced significantly higher mortality of N. viridula than any of the insecticides compared with the control. Mortality of stink bugs was significantly higher at 5 gallon compared with 2 gallon rates. Deposition characteristics of insecticides were discussed relative to mortality of N. viridula on cotton.
