Abstract/Contents:"Insecticides are widely use [used] to manage pests in turfgrass. A common assumption across the industry is that once a treatment is applied, residual control will protect the turf planting for 1- to 2-wk or even longer. These experiments evaluated the residual control for fall armyworm provided by treatments of 8 insecticides applied at several rates during either late July or early Sep. 1996. Field plots of Common bermudagrass were treated with various insecticides and grass samples were harvested sequentially in time and fed to 4- or 5-d-old fall armyworm, (Spodoptera frugiperda) larvae in the lab. Treatments with chlorpyrifos (Dursban), diazinon, bifenthrin (Talstar and Biflex), lambacyhalothin (Scimitar), acephate (Orthene TTO and Pinpoint), carbayl (Sevin) and deltamethrin at 1 or more rates provided 100% control of the larvae within 48 h exposure on grass harvested 1 d after field treatment. Maximum residual control of >90% was provided as follows; lambacyhalothin (13 d or longer), chlorpyrifos (9 d), acephate (4 d), diazinon (4 d), deltamethrin (4 d), carbaryl (3 d), and bifenthrin (1 d) after the grass was treated. Seasonal or environmental conditions appeared to impact residual time. The method of treating field plots and exposing the treated grass sequentially in time to larvae appears to provide an accurate estimate of the long term potential control for turf insecticides."
