Abstract
Based on the study of dimensional characteristics of reeds, a sprayer is proposed for the treatment of panicles of reeds growing in the elements of the irrigation system of rice checks. The boom of the offered sprayer has an original shape, sprayers of which are located along the trajectory of a parabola, taking into account the placement of the upper points of the panicles across the width of the channel and equipped with a protective chamber device, made in the form of an Archimedes spiral with a spiral pitch equal to at least 20 cm, the offset of the spiral center from the axis of the spraying nozzle vertically is equal to the spiral pitch 20 cm, and from the location of the spraying nozzle to the bottom treatment zone of panicles 40 cm.
