Abstract

The invention discloses a pesticide composition containing tolfenpyrad and fluopyram, and belongs to the technical field of pesticides. The active ingredients of the composition comprise the tolfenpyrad and the fluopyram, wherein the ratio of the tolfenpyrad to the fluopyram is 1:40-60:1. The pesticide composition has the advantages that by reasonably applying preparations on target crops, insectpests on the target crops can be effectively prevented and controlled, diseases are also treated, for example, the root-knot nematodes on carrots are prevented and controlled while phyllotreta striolata on the carrots are prevented and controlled, and the time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing tolfenpyrad and fluopyram. Background technique [0002] The damage characteristics of carrot yellow striped flea beetle: both adults and larvae can cause damage. Adults bite the leaves, causing many small holes, especially the young parts, often causing the seedlings to stop growing, or even the whole plant to die. Flower buds and pods of seed plants can also be damaged. The larvae damage the roots, bore the vegetable root skin into many curved insect passages, bite off the fibrous roots, and make the leaves above the ground turn yellow and wilt and die. After the fleshy roots of carrots are damaged, many black spots are formed on the surface, and finally turn black and rot. In addition, wounds caused by adults and larvae are prone to spread soft rot. [0003] Carrots are infested by root-knot nematode (Merloidogyne incognita...
