Domateste Kök ur nematodu Kontrolünde Ticari Biyonematisit ve Kitosan Kombinasyonları.

In this study, the effect of combination of three commercial bionematicides, Burkholderia rinojensis A396 strain (Majestene®), Paecilomyces lilacinus 251 strain (Bio nematon®) and Quillaja saponaria (QL-Agri®), with chitosan on gall and egg masses formed by root knot nematode Meloidogyne incognita was investigated on tomato under controlled conditions. The study was carried out in plastic pots with 9 applications of bionematicides alone and together with chitosan. A thousand Meloidogyne incognita second stage juvenile (L2)/1ml was used as nematode inoculum and the recommended doses of bionematicide applications to the field (Majestene® 0.4 ml/l, Bio nematon® 5 ml/l, Velum Prime® 0.16 ml/L, QL-Agri® 0.8 ml/L) with nematode inoculation were applied to the potting soil. Chitosan application was made 5 ml of 1% liquid suspension required for each potting soil. After sixty days, the roots were evaluated according to the index value of 1-9 gall and egg mass. The gall and egg mass index were found to be 4.2 and 3.8, respectively in only chitosan application. While the gall index changed between 3.0-4.8 in only bionematicide applications, it changed between 2.6-3.8 in combination with chitosan. As a result, the application of bionematicides together with chitosan significantly reduced the number of galls and egg masses in the roots of tomato and increased the success in the control against M. incognita.
