Abstract:
A combination of a new sprayer and new chemicals was developed and tested in an effort to reduce the toxicity to mammals of pesticides used in cotton fields. For the application of these materials, and also when dosage reduction is desired, uniform deposition on all parts of the plant is required. In order to comply with these requirements the new sprayer utilizes a vertical boom with air assistance. The use of air as the droplet carrier significantly improved the amount and the uniformity of the spray deposit, in spite of the small gap between the nozzle and the canopy. Deposit improvement on the underside of the leaves was mainly achieved by directing the air stream obliquely upwards.
