On Aug 3, a caged boll weevil study was initiated at Mississippi State University to determine the residual effectiveness of several insecticides. Plots were 2 rows wide (0.9m) and 30.48 m long. Two buffer rows separated plots. Insecticide applications were made with a CO2 powered hand sprayer equipped with two TX4 spray tips/row delivering 65 liter/ha at 2.1 kg/cm2. Adult boll weevils were obtained from the Gast Rearing Facility at MSU. Cotton-Dacron cages (0.9 m x 0.65 m) were placed over individual cotton plants and tied securely at the base of the stalk.
