Abstract

The invention discloses a pesticide composition containing tofenpyrad and fluopyram, which belongs to the technical field of pesticides. The active ingredients of the composition of the invention include tofenpyrad and fluopyram, wherein the ratio of the two is 1 :40~60:1. The pesticide composition of the present invention is applied to target crops through a reasonable preparation, which can effectively prevent and control insect pests on target crops, and also treat diseases, such as preventing and curing flea beetle on carrots, and can also prevent root-knot nematodes of carrots, saving Save time and labor.

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...
