Plant parasite nematodes (BPNs) especially root-ur nematodes (Meloidogyne spp.) (KUNs) are nonmatodes that are widely distributed and cause significant loss of productivity in a wide range of products. The important KUN species are Meloidogyne arenaria Chitwood (1949), Meloidogyne exigua Goeldi, 1892, Meloidogyne graminicola Golden and Birchfield, 1965, Meloidogyne hapla Chitwood, 1949, Meloidogyne incognita (Kofoid and White, 1919), Meloidogyne javanica (Treub) Chitwood, 1949 and Meloidogyne mayaguensis (Kofoid and White, 1919). The distribution of BPNs in different guests and locations has been studied in Turkey. As a result of the studies, a total of 240 BPN species of 56 species associated with the Tylenchida (Nematoda) team have been detected in Turkey. These nematod species have been found associated with 66 plants from 48 different regions of the country. As KUN species in our country, M. incognita, M. arenaria, M. javanica and M. are the most common species found with the pill. M. incognita and M. javanica are among the leading species that cause serious problems in agriculture and coverage production. Nematisites do not ensure the long-term suppression of KUNs, which will result in increasing restrictions on environmental and human health concerns on their use. The diagnosis of the KUN species in the samples taken from the province of Tokat (Turkey) was made using classic methods through morphological and morphometric characteristics. Meloidogyne (M. incognita) and M. javanica (M. javanica) for the creation, renewal and production of their cultures, sensitive tomato fides [SC-2121 tomato species (Solanum lycopersicum L.)] were produced in the greenhouse shells. The study examined the sensitivity and durability of the tomato genotypes applied in terms of egg package number and scale value. Accordingly, the Domates-79 and Domates-90 genotypes with the highest number of egg packages in M.i and M.j applications were ranked in a scale of 1 and 2 against all root-urgen nematodes (M.i and Mj) used in the trials (9.2±2.74; 8.2±1.58; 2.8±1.24 and 9.4±2.46). All other applications are included in sensitive groups with scale values of 3, 4 and 5, since the number of egg packages is above 11.

Plant-parasitic nematodes (PPNs), particularly Meloidogyne spp., root-knot nematodes (RKNs), are widely distributed and cause significant yield losses in a wide range of crops. Major RKN species are Meloidogyne arenaria Chitwood (1949), Meloidogyne exigua Goeldi, 1892, Meloidogyne graminicola Golden and Birchfield, 1965, Meloidogyne hapla Chitwood, 1949, Meloidogyne incognita (Kofoid and White, 1919), Meloidogyne javanica (Treub) Chitwood, 1949 and Meloidogyne mayaguensis (Kofoid and White, 1919). PPNs, host association and distribution in different localities of Turkey have been surveyed. A total number of 240 species of PPNs belonging to 56 genera of Tylenchida (Nematoda) detected in Turkey. These PPN species found associated with 66 plants from 48 different localities of the country. In Turkey, M. incognita, M. arenaria, M. javanica and M. hapla are the most commonly found species, with M. incognita and M. javanica causing serious problems to a number of economically important agricultural and greenhouse crops. Nematicides do not provide long-term suppression of RKNs, and environmental and human health concerns are resulting in increased restrictions on their use. Identification of RKNs obtained from the samples collected from Tokat (Turkey) province were made using morphological and morphometric features using classical methods. For the production and renewal of the cultures of the RKN species [M. incognita (M.i) and M. javanica (M.j)] a susceptible tomato variety [SC-2121 variety tomato (Solanum lycopersicum L.)] was produced in greenhouse pots. In this study, the tomato varieties that were applied were determined to be susceptible and resistant (based on the number of egg mass and index value). Results indicated that Tomato-79 and Tomato-90 varieties were resistant to all root knot-nematodes (M.i and M.j) used in the experiments (9.2 ± 2.74; 8.2 ± 1.58, 2.8 ± 1.24 and 9.4 ± 2.46). All other genotypes were in sensitive groups with 3, 4 and 5 scale values as the mean number of egg messes were above 11.
