Spraying deposition of pesticide on apple crop
The objective of this work was to evaluate the distribution of pesticide deposition on two apple varieties (Malus domestica Borkh). Liquid spray with Rhodamine as tracer was sprayed by trailed air-carrier equipment, with two types of calibrations. In one of them it was used the JA-1, JA-2 and JA-3 cone nozzles, and in the other, AVI 110 ISO-04 fan nozzles and JA-1 cone nozzles. There were no differences among the calibrations, but the deposition on the plants decreased from the apical to the basal region. On all tested calibrations, 25% of the applied tracer was wasted on the soil.
