Abstract By in vitro experiments and greenhouse test，6 acid compounds’effects on controlling tomato（Lycopersicon esculentum Mill.）root knot nematode and tomato plants growth were determined．The results of in vitro experimental showed that the toxicity of formic acid on root knot nematode virulence was the strongest，followed by propionic acid，and that of malic acid was the weakest．The result of testing greenhouse control effect and influence on plant growth showed that oxalic acid had higher control effect on tomato root knot nematode and less influence on plant growth．
