Resumo: | The aim of this study is to compare the application efficiency between costal manual sprayer and an engine powered. Trapezoidal architecture of coffee plants and leafs position constitute a large obstacle to spraying. In this context, application technology became an important factor. One alternative is the use of air assistance to accomplish the distance between the sprayer and the application target. This experiment was entirely randomized with four replications, comparing the two spraying equipments regarding the coverage percentage in three different heights (superior, median and inferior), two different leafs position (external and internal) and two foliar faces (abaxial and adaxial), totalizing 48 plots. The spray rate used was 100L.ha-1, composed by a water solution with fluorescent tracer. Based on results observed from leafs located in the external position and leafs from internal position of the median height, they denote that the utilization of air assistance is more efficient in leafs percent coverage in coffee plants than a conventional sprayers. This result was especially noted at the abaxial leaves side in the external position, as well as on both sides of the leaves positioned internally and in the plant medium. |

A arquitetura trapezoidal da planta de café e o posicionamento das folhas constituem sérios entraves à aplicação. Nesse contexto a tecnologia de aplicação torna-se um fator de grande importância. Uma alternativa é o uso de assistência de ar para que se vença a distância entre o pulverizador e o alvo pretendido. O experimento foi delineado no esquema inteiramente casualisado com quatro repetições, comparando os dois equipamentos de pulverização quanto à porcentagem de cobertura em três diferentes alturas (superior, médio e inferior), duas diferentes posições de folhas (externas e internas) e duas faces foliares (abaxial e adaxial), totalizando 48 parcelas. A taxa de aplicação utilizada foi de 100L.ha-1, sendo a calda composta por traçante fluorescente diluído em água. Com base nos resultados observados tanto para as folhas situadas na posição externa, como para as folhas da altura mediana na posição interna, denotam que a utilização do pulverizador motorizado (com assistência de ar) foi mais eficiente na cobertura das folhas do cafeeiro do que o pulverizador convencional. Esse resultado foi especialmente notado na face abaxial das folhas situadas na posição externa da plantas, assim como, nas duas faces das folhas posicionadas internamente e na parte mediana.UEL2011-10-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/515110.5433/1679-0359.2011v32n4p1417Semina: Ciências Agrárias; Vol. 32 No. 4 (2011); 1417-1422Semina: Ciências Agrárias; v. 32 n. 4 (2011); 1417-14221679-03591676-546Xreponame:Semina.
