The 1987-1992 microplots experiment was conduced in agricultural field conditions under routine crop, and herbicide rotation. Over the experimental time only the endoparasitic species, Pratylenchus neglectus revealed significant changes in the population dynamics. In a sugar beet the nematode population decreasad in microplots treated with chloridazon (3.25 kg/ha) or cycloate (4.44 kg/ha) but increased in the control. In a winter rape the population ofP neg/ecrus increased in microplots treated with benazolin (0.45 kg/ha) but it decreased in the control. The observed trends in the dynamics of the nematode population persisted for one year only, and they were changed with the rotation of crop and herbicides. No differences betwen herbicides treated, and control microplots were observed with linuron + bentazone (10 kg/ha + 1.5 kg/ha, respectively) was applied to pea culture, metabenzthiazuron (2.8 kg/ha) was applied to a winter wheat, and MCPA as sodium salt + dicamba as sodium salt (0.725 kg/ha + 0.08 kg/ha, respectively) was applied to a spring wheat. The examined crops and herbicides did not markedly affect the population dynamics of ectoparasitic Tylenchorhynchus dubius, Helicotylenchus digonicus and Mesocrico nema curvatum.

Globodera artemisiae (Eroshenko et Kazachenko, 1972) was found in Poland in autumn of 2004. The nematodes developed on Artemisia vulgaris L. Morphological and morphometric characteristics of the Polish population correspond to earlier known populations from Far East of Russia, Armenia, China, Germany and Sweden. The traditional identification was confirmed by molecular methods. On the basic of rDNA sequences of G. artemisiae, deposited in GenBank the product of expected size was obtained. Subsequently, the results were confirmed by sequencing analysis.
