ABSTRACT
Secondary pests of concern in South Carolina cotton include stink bugs, armyworms, and soybean looper. Stink bug control is usually maintained by multiple pyrethroid sprays applied for cotton bollworm. Methyl parathion is added to these pyrethroid bollworm sprays when stink bugs exceed recommended thresholds. The beet armyworm is the dominant armyworm species; none of the currently recommended chemicals will consistently control this pest. Two new compounds, Pirate and Confirm, have given adequate control on established populations. Efficacy trials in 1995 indicated Pirate to be the best material against beet armyworm. With soybean looper, none of the currently recommended chemicals provide adequate control. Of the new compounds tested only Pirate provided adequate control of this pest.
