Laimburg brush sprayer vs. standard sprayer, with and without fan support: which technology comes out top in a drift test?

Abstract

One of the most important purposes of plant protection treatments, in addition to optimum active substance distribution, is to deposit the largest amount of active substances in a target area. In this trial, four different application techniques (an innovative application technique with and without rotating brushes and a standard sprayer with and without fan support) were examined to evaluate the amount of active substance spread over a target area and adjacent border rows. The spray brush with rotating brushes and the standard sprayer without fan are interesting treatment techniques that help to increase the amount of active compound deposited on the targeted area and at the same time, they help to reduce drift compared to the application technique used as standard.
