Abstract :In this research, the effect of soil, foliar and simultaneous soil+foliar applications of chitosan on gall and egg mass of root-knot nematode Meloidogyne incognita was investigated in tomato plants under controlled conditions insert ignore into journalissuearticles values(24±1°C, 60±5% RH);. Fluopyram insert ignore into journalissuearticles values(0.16 ml/L); was used as positive control while only nematode-treated plants were considered as negative control. The study was set up in a randomized plot design with 5 replications for each application. The liquid suspension of chitosan diluted at 1% was used. In soil application, 5 ml was applied to each pot by using a graduated cylinder while in foliar application, the liquid suspension at 1% was applied using a portable hand sprayer until the solution was finished. The study was evaluated according to the 1-9 gall and egg mass index 60 days after inoculation of nematodes. The lowest gall insert ignore into journalissuearticles values(2.8); and egg mass insert ignore into journalissuearticles values(2.4); indexes were detected in the simultaneous soil+foliar application and took place in the same statistical group with the positive control nematicide. It was determined that the nematicidal effect of chitosan has increased in the case of combined soil and foliar applications. These results support the fact that chitosan applications are successful in the control of root-knot nematode.
