Coastal Bermudagrass, Fall Armyworm Suppression, Tifton, 1977

A ‘Coastal’ bermudagrass (Cynodondactylon (L.) Pers.) hay pasture (5-6 inch high) growing in Tifton sandy loam soil and possessing a considerable amount of crabgrass was moderately infested with fall armyworms, and low densities of Mocis spp. and other foliage-feeding Lepidopteran larvae. Treatments were applied in water as 45 gal/acre with a Solo® 425 back-pack sprayer having a 8006 nozzle, except that a shaker can was used for the bait. Plots were 10 x 12 ft and surrounded by 20 ft of untreated grass. The design was a randomized complete block with 4 replications. Six sweeps with a 15 inch (in dia) net were taken on 2 sides of the plot, counted in the field and dumped back into the plot. Air temperature during the test period was ca. 9-32°C and little rain occurred.
