摘要：

In order to determine the nematicidal activity of Tea saponin(TS),the oil tea cakes were processed through degreasing,dealcholizing,and extracting with n-butyl alcohol,the crude powder of 84.6% TS was obtained.The TS powder was evaluated against 4 plant nematodes and 1 soil nematode.The results indicated that TS exhibited modest nematicidal activity against the 4 plant nematodes,but exhibited no nematicidal activity against Rhbiditis sp..The pot experiments showed that infective inhibition of TS against Hrischamanniells oryzae is 71.1%,galls on Trichosanthes kirilowii caused by Meloidogyne incognita was reduced by 88.9% when the bare-root-tip was placed in TS solution for 3 h.
