Control of root-knot nematodes (Meloidogyne spp.) in pepper

Root-knot nematodes of genus Meloidogyne are the most important nematode pests in vegetables, present on more than 2500 different plant species widely. Production of vegetables in polythene greenhouses in Croatian county of Baranya increasing continuously as well as number of producers. In polythene greenhouses in Lug (Baranya), on 80m2, in 2000 year, the symptoms of root-knot nematodes were noticed on peppper. Nematodes were extracted from the soil samples by "bottle technique" (Seinhorst, 1956). Soil was sampled also in 2001 before planting. Number of Meloidogyne species recorded was 601 individuals/100 ccm of soil, and it was decided to applicate nematocide Basamid granulat G (dazomet) in dosage of 60 g/m2. Basamid were incorporated into soil on 26 of March and covered by plastic sheet until 24 of April. After removing the plastic sheet the soil was well aired, and "Kresse test" of phytotoxicity showed negative results. Number of Meloidogyne before planting the pepper was 40 individuals/100 ccm of soil. After a month there wasn't any root- knot nematode noticed in the soil samples, and at the end of the season it was estimated again 18 individuals/100 ccm of soil. Incorporation of Basamid into the soil reduced the population of root-knot nematodes by 93%.
