Abstract
Grapevines (Vitis vinifera L.) are a good option for Brazilian growers using large amount of labor, resources and technology. Itália variety and its mutations require careful treatments since they are very prone to develop diseases. The aim of this study was evaluate the influence of droplet size and spray volume in the chemical deposition on grapevine leaves. The increase of the spray volume provided better deposition. There was no interaction between droplet size and spray volume as well as there was no influence of droplet size on the spray deposits on the leaves. The method can be considered adequate for the propose of this work.

A cultura da videira (Vitis vinifera L.) tem se mostrado como alternativa cada vez mais viável dentro da agricultura brasileira, utilizando grande contingente de mão-de-obra, elevado consumo de insumos e adoção de tecnologias atualizadas. Por serem altamente suscetíveis às doenças fúngicas, a variedade Itália e suas mutações somáticas exigem um cuidadoso tratamento fitossanitário, podendo necessitar de mais de 50 pulverizações num único ciclo. O objetivo deste trabalho foi avaliar a influência do tamanho de gota e do volume de aplicação na deposição de calda nas folhas da videira. Os resultados mostraram que o aumento do volume de calda propiciou maior depósito sem, entretanto, alterar o nível de perdas. Não houve interação entre tamanho de gotas e volume de calda, nem influência do tamanho das gotas no depósito de calda nas folhas. O método utilizado mostrou-se adequado aos objetivos deste trabalho.
