| Abstract/Contents: | "Portions of a bermudagrass green at the Ft. Lauderdale Research Center were divided into 1.5 X 3.0 m 2 (50 ft2) plots. A 61-cm-wide untreated buffer zone of turf was left between plots. Populations were sampled by sprinkling 1 liter of 0.02 to 0.03 % pyrethrin, emulsified in the water with a wetting agent, on 0.37 m2 (4 ft2) of turf in each plot. An additional liter of water was sprinkled over the sample area to wash the pyrethrin solution to the webworm larvae on or just below the soil surface. Larvae which came to the turf surface within a 10-min period were counted. Successive samples within a plot were taken in different locations. Plots were assigned to 4 replicates by pretreatment counts, in a RCB experiment and treatments were applied 3 Aug. The EC and WP ( in solution in water) formulations of inseciticdes were applied with an Ortho brand hose-end siphon sprayer. All other test inseciticides were provided by S.C. Johnson & Son, Inc., as hose-end aerosol formulations (HA). Aerosol formulations also contained a foam tracer. All treatments provided control of the tropical sod webworm within 3 days. Populations were reduced to less than 2 larvae per 0.1 m 2 (a ft2) (less than a damage threshold for this pest) and reinfestation of the test area did not occur within the 28 day test-period. No phytotoxicity of the bermudagrass was observed due to any of the treatments. These same insecticides evaluated as other formulations have provided good control in previous experiments." This test was done on Tifgreen bermudagrass. |
