Resumo: | Manual backpack sprayers are widely used in rural properties in Brazil. However, studies that assess their working characteristics, especially spray tip models and working pressure conditions, are scarce. Thus, the aim of this study was to assess how much the working pressure and spray tips influence the distribution quality of phytosanitary spray solutions in manual backpack sprayers. Four spray nozzles (standard flat-fan Magnojet TP11002, turbo flat-fan TeeJet TT11002, hollow-cone TeeJet TXA8002, and disc-core) were assessed in a patternator table at 1, 2, 3, and 4 bar. Analyses of spray distribution profile were performed by symmetry and the coefficient of variation (CV) analysed by the Tukey’s test (p < 0.05). Spray tip models and working pressure influenced in more than 100% the distribution uniformity values of spray solution and in about 50% the useful range of the phytosanitary treatment. Among the models assessed in this study, the turbo flat-fan spray nozzle presents the best set of characteristics to be indicated for manual backpack sprayers aiming at field phytosanitary treatments. |

Entretanto, são escassos os trabalhos de pesquisa que avaliem as suas características de trabalho, sobretudo modelos de ponta de pulverização e condições de pressão de trabalho. Desta forma, o objetivo deste trabalho foi avaliar quanto os modelos de pontas e a pressão de trabalho influenciam na qualidade da distribuição de caldas fitos-sanitárias com pulverizadores costais manuais. Foram avaliados em mesa de deposição quatro modelos de pontas de pulverização (jato plano convencional Magnojet TP 11002; jato plano defletor Teejet TT 11002; jatos cônicos vazios TeeJet TXA 8002 e “chapinha” original), a 1, 2, 3 e 4 bar de pressão. As análises do perfil de distribuição dos jatos foram realizadas por simetria e o coeficiente de variação analisado pelo teste de Tukey (p < 0,05). Os modelos de pontas de pulverização e a pressão de trabalho influenciaram em mais de 100% os valores de uniformidade de distribuição da calda, e cerca de 50% na largura da faixa útil de tratamento fitos-sanitário. Dentre os modelos avaliados neste trabalho, o de jato defletor é o que apresenta o melhor conjunto de características para ser indicado a equipar os pulverizadores costais manuais para os tratamentos fitossanitários de campo.School of Agricultural and Veterinary Sciences, Universidade Estadual Paulista “Júlio de Mesquita Filho”School of Agricultural and Veterinary Sciences, Universidade Estadual Paulista “Júlio de Mesquita Filho”Instituto BiológicoUniversidade Estadual Paulista (Unesp)Marangoni, Alcides [UNESP]Da Costa Ferreira, Marcelo [UNESP]2021-07-14T10:33:33Z2021-07-14T10:33:33Z2019-12-2info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article-application/pdfhttp://dx.doi.org/10.1590/1808-1657000442018Arquivos do Instituto Biológico.
