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.
