"An air-assisted sprayer equipped with two reversed rotation fans was evaluated in a peach orchard. The effects on the spray deposition of the forward speed, the air volumetric flow rate, and the number of activated fans were analyzed," researchers in Huesca, Spain report.
"Spray mixtures contained manganese chelate as a tracer Spray deposition was evaluated qualitatively through visual estimation of water-sensitive papers and quantitatively by analysis of filter papers using an atomic absorption spectrometer. Deposition and canopy penetration increased when the air volumetric flow was increased for most of the sampling points. The forward speed had no ...
