ABSTRACT
A field study was conducted during 1999 to determine the effect of experimental drift control adjuvants on cotton defoliation, boll opening, and shoot regrowth, and a laboratory study was conducted to determine the diameter of spray droplets using different spray nozzles and spray pressures. The harvest-aid chemicals with their descriptions and manufacturers are listed in Table 1.
