Insecticide coverage can be improved by the addition of spray carriers or additives, such as oils. Canopy penetration can be improved by increasing pressure, which will produce smaller spray droplets. Applicators must maximize coverage for insecticides to reach the lower plant, where soybean loopers feed in their early stages. No currently registered insecticide offers adequate control of soybean loopers on cotton. At least two applications may be necessary to prevent economic damage.
Accurate surveys are necessary to detect the caterpillars before damaging foliage loss has occurred.
In the meantime, entomologists will continue the search for more effective controls and management practices to prevent soybean looper damage in cotton. Use chemicals only according to the directions on the label. Follow all directions, precautions, and restrictions that are listed. Trade names are used only to give specific information.
