Evaluation of Low-Drift Nozzles in Agrochemical Applications in Orchards

Fruit production demands several phytosanitary treatments per year. The efficiency of these treatments is affected by product loss because of drift, a situation that is aggravated by frequent high winds and the presence of a substantial rural population. The objective of this study was to evaluate t...
