Meloidogyne spp nematodes cause pathogenic root-knot and affecte on the yield of Chinese cabbage. Studying of methods controlling root-knot nematodes on Chinese cabbage is needed to increase yield and product quality. Using different commercial nematicides and different concentrations of Ethoprophos and Abamectin was designed of 4 treatments as follows: Abamectin 18 g/l
Abamectin 20 g/l
granular Ethoprophos 10 percent
emulsifiable liquid Ethoprophos 200 g/l. The results showed that Ethosprothos 10 percent have mandatory effects in killing nematodes at high level at 67.2 percent after 15 days of treatment and Ethosprophos 200 g/l reached at 65.2 percent after 30 days of treatment and the ratio of rootknot nematodes and level of infection were also lower than Abamectin 20g/l. Propose yield and yield of two plot of Ethoprophos was not different from that of Abamectin but the yield was different compared to control plot (p or
