Resumo: | In the agricultural sprays more importance is generally given to the pesticide and less to the application technique, though the losses can overpass 70%. The high temperature and the low relative humidity of the air have important effects on the spraying of pesticides, causing faster evaporation of the drops. The objective of this research was to evaluate the variation of the deposition spray with three types of nozzles in different hours of the day (hollow cone, reduced drift and air inclusion). A saline solution was applied in PVC glasses to which distilled water was added for electric conductivity reading. In a general way the deposition of the flat fan nozzles and the anti-drift ones had no difference and was not affected by the variation of the temperature and relative humidity, but the hollow cone nozzle presented variations of more than 100%. The results showed that the hollow cone deposition was significantly affected by meteorological conditions variations. |

A alta temperatura e a baixa umidade relativa do ar têm importante efeito sobre a pulverização de produtos fitossanitários, causando evaporação mais rápida das gotas. O objetivo deste trabalho foi avaliar a variação da deposição da calda de pulverização com três tipos de pontas (jato cônico vazio, jato plano e antideriva) nas diferentes horas do dia. Uma solução salina foi aplicada em copos de PVC, aos quais, foram adicionados água destilada e deionizada, para leitura da condutividade elétrica. De maneira geral as pontas de pulverização de jato plano e antideriva não tiveram a deposição afetada pela variação da temperatura e umidade relativa do ar e não diferiram entre si, mas o mesmo não ocorreu com a ponta de jato cônico vazio onde a variação foi de mais de 100%. Os resultados mostraram que a deposição das gotas produzidas pela ponta de jato cônico vazio foi significativamente afetada pela variação das condições meteorológicas.UEL2008-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/281610.5433/1679-0359.2008v29n2p293Semina: Ciências Agrárias; Vol. 29 No. 2 (2008); 293-298Semina: Ciências Agrárias; v. 29 n. 2 (2008); 293-2981679-03591676-546Xreponame:Semina.
