Nematicidal composition

The invention relates to nematicidal composition. The effective ingredients of the nematicidal composition comprise avermectins B2 and Imicyafos in the mass ratio being (100:1)-(1:100). The avermectins B2 and Imicyafos have a remarkable synergistic effect after being compounded and can be used for controlling nematodes in vegetables, fruit trees, oil crops, grain crops, sugar-yielding crops, medicinal plants, cotton and hemp crops, gardening plants and other plants and places. 本发明涉及种杀线虫组合物，其有效成分为阿维菌素B和Imicyafos，两者的质量比为100:1-1:100。阿维菌素B与Imicyafos复配后具有明显的增效作用，可用于蔬菜、果树、油料作物、粮食作物、糖料作物、药用植物、棉麻类作物、园艺园林类植物等植物及场所的线虫防治。
