MEWES, Walter Luis Castro et al. Application of pesticide in eucalyptus spray tyre. Rev. Árvore [online]. 2013, vol.37, n.2, pp.347-353. ISSN 0100-6762.

The study was conducted to evaluate the parameters of the spraying in tree crops. The efficiency and droplet deposition on the target is important to raise the profitability of timber production, reducing environmental risks to health from the applicator, increasing effectiveness in combating pests and diseases. The aim of this study was to evaluate the operational parameters of a pneumatic spray for application to adult eucalypt forests, through the study of droplet density and percentage of coverage, the volume median diameter, the coefficient of homogeneity of relative amplitude and uniform volumetric distribution of the syrup. The sprayer was efficient for the application of pesticides in adult trees of eucalyptus. It was observed that all treatments showed density and droplet size satisfactory for spraying. Regarding the parameters percentage of coverage and uniform volumetric distribution, the best results occurred when we used the volumetric rate of 27 mL and 20.2 m3 of canopy. As the volume index of 20.2 mL m3 of canopy suitable for spraying.
