Experimental ultra-low-volume ground equipment developed for spraying sweet corn was modified and tested for spraying cotton. A wide angle nozzle tip (160°) was developed to give lateral canopy coverage to the plants. One nozzle per row positioned to spray downward from 6 inches above the plants resulted in insect control equal to that obtained with conventional equipmentunder heavy insect pressure. Yield data showed no significant differences among equipment or materials used. However, plots treated with the TULV sprayer using malathion - ambithion (0,0 -dimethyl 0-4- nitro- m - tolyl phosphorothioate) and malathion-methyl parathion consistently produced the highest yields
