Nematode killing composition

The invention relates to a nematode killing composition. Effective components of the composition are avermectin B2 and fluopyram, and a mass ratio of the avermectin B2 to the fluopyram is 100:1 to 1:100. The avermectin B2 and fluopyram are compounded to realize obvious synergistic effects, so the composition can be used in the prevention and control of nematodes on fruit trees, vegetables, grain crops, oil-bearing crops, sugar-bearing crops, linen-cotton crops, gardening and garden 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和氟吡菌酰胺，两者的质量比为100:1-1:100。阿维菌素B与氟吡菌酰胺复配后具有明显的增效作用，可用于果树、蔬菜、粮食作物、油料作物、糖料作物、棉麻类作物、园艺园林类植物等植物及场所的线虫防治。
