Sažetak

The management of plant parasitic nematodes in root vegetable crops requires an integrated approach of the application of agro‐technical measures and biological pesticides, since chemical nematicides are not allowed. This study was undertaken to assess the impact of the four‐year crop rotation on the population of Meloidogyne hapla (northern root knot nematode) and efficiency of bionematicide NemakeyTM in suppressing population of Paratylenchus bukowinensis (pin nematode). The research was carried out in Tvrđavica in 2016, in the summer crops of carrots and parsley. Populations of root knot nematodes were reduced when cabbage, grown on plastic was introduced in crop rotation. Populations of P. bukowinensis ranged from 155 to 470 nematodes in 100 mL of soil prior sowing of carrot and parsley, and the peak of the population was at harvest, when 217 to 920 nematodes in 100 mL of soil were detected. Bionematicide did not suppress population of pin nematodes, and both crops suffered minimum of 50% of yield damage. Symptoms of pin nematode and root knot nematode damage are similar, whereas pin nematodes do not cause formation of root galls and development of secondary roots. To the best of our knowleedge, these are the first findings of economically important damages from P. bukowinensis in Croatia on carrots and parsley.
