摘要

A device for applying insecticide sprays in agricultural trials has a rolling equipment-carrying cart with a spraying device, several small containers (2) of concentrated insecticide spray, at least one larger container for a liquid carrier that acts as a diluting agent, dosing means for dosing the liquid carrier and a mixer (7, 8) in which the concentrated insecticide spray and the liquid carrier are mixed into an insecticide spray having the desired concentration, as well as means for feeding the insecticide spray to the spraying device. In order to improve the efficiency of agricultural trials, the accuracy and reproducibility of the trial results and reduce the trial costs, the small containers contain different concentrated insecticide products, all small containers are arranged in a row in a rotary magazine and are successively emptied in the desired order of the trials into the mixer to prepare samples of insecticide spray.
