Thirty insecticides were evaluated for control of mixed populations of sod webworms, Herpetogramma spp. and Crambus spp., on 'Tifway' and 'Tifgreen' bermudagrass, Cynodon spp. All of the chemicals except one provided control with at least one rate of formulation evaluated. Fonofos, primiphos-ethyl, and chlorpyrifos provided partial residual control of the second generation of web worms when plots became reinfested 3 or 4 weeks after treatments. No evidence of resistance to any of the currently recommended insecticides was shown.
