Abstract

The invention relates to a pesticide for pine wood nematode of masson pine. The pesticide comprises Sophora alopecuroides L., Veratrum nigrum L., trifoliate jewelvine root or stem, Tagetes erecta L., Sichuan chinaberry, virgate wormwood, stemona tuber, bitter bamboo and blackberry lily rhizome. The pesticide is prepared by weighing the above-mentioned components in proportion, crushing the components, adding the crushed components into ethanol, carrying out extraction, extracting herb residue with ethanol again, mixing herb soups collected after two extraction operations, subjecting the obtained mixture to pressure-reduced evaporation so as to obtain a viscous material and diluting the viscous material. Effective ingredients extracted from the components cooperate with each other, so the pesticide can effectively kill pine wood nematode and Monochamus alternatus Hope, controls propagation mediums of pine wood nematode, cures attacked pines, does not incur drug resistance and poses small influence to environment and ecology.
