Assessing the influence of air speed and liquid flow rate on the droplet size and homogeneity in pneumatic spraying

摘要

BACKGROUNDThe efficacy of treatments in vineyards largely depends on the necessary balance between leaf coverage and spray drift and, therefore, knowledge about droplet size is of major importance, but scarce scientific information is available on pneumatic spraying, often adopted in this crop. The objective of this work was to obtain the relationships between the droplet size spectra characterization parameters and the main affecting factors in pneumatic nozzles.
