Abstract:ResuIts of field tests using controlled sizes of droplets showed that uniformity of deposit in the treated area increased by both controlling sizes and by increasing the size of droplets. Drops per square inch deposited within cotton foliage were sampled on l-ft intervals. The deposit at a particular level was found to be 50% of the deposit taken 1-ft above the given sample.
A droplet of approximately 140 m. appears to be the minimum size that can be released, without other con- trolling factors, and be deposited dependably in or near the treated area.
