Paper presented the results of study on irregularity of concentration of biological plant protection agent - insectivorous nematodes Steinernema feltiae in deposition liquid. The experiments with flat fan nozzles TeeJet XR 8002 for height 0,375 and 0,75 m above the measuring-table, and 11004 for height 0,25 and 0,5 m, were carried out. The spray liquid was collected to measuring glass. The influence of spraying height on irregularity of nematodes concentration in measuring glass was found.
