The commercical application of imazethapyr influenced upon endoparasitic lesion nematodes Pratylenchus ssp. onli.The nematode population decreased in the plots treated with imazethapyr at rates of 0.08 and 0.16 g a.i. ha-1 from 13.9 to 42.8% and from 27.1 to 50.7% respectively.The observed trend in the dynamics of the nematode population persisted for one year onli and was changed with the crop rotation.Imazethapur did not markedly effect the population dynamics of ectoparasitic species:Helicotylenchus ssp., Paratylenchus ssp., Trichodorus ssp. and Xiphinema ssp.
