Problems solved by technology

However, the long-term use of a single type of pesticide is likely to promote the resistance of pests to a certain extent. For this reason, farmers often use more pesticides to achieve the purpose of eliminating pests.
However, there are problems in using this method, which will cause greater pollution to the environment and pesticide residues, and at the same time indirectly increase the cost of pesticides for farmers.
[0007] The compound composition of piperacrid and carbosulfan has not been reported yet

Abstract

The invention discloses a synergistic insecticidal composition containing paichongding and carbosulfan. The synergistic insecticidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A refers to paichongding, the active ingredient B refers to carbosulfan, the weight ratio of the active ingredient A to the active ingredient B is 1:85 to 1:85 and preferably 1:50 to 1:50, and the total weight percentage of the two active ingredients in the composition is 5-70%. The composition can be prepared into one or more dosage forms selected from wettable powder, a suspending agent and a microemulsion. The composition disclosed by the invention can be used for preventing and controlling plant hoppers or aphids generating hazards to various crops.

Description

technical field [0001] The invention relates to an agricultural insecticide composition, in particular to a synergistic insecticide composition containing pichridam and carbosulfan, which can be used to prevent and control agricultural pests, especially planthoppers and aphids. Background technique [0002] Pichamid is a new neonicotinoid insecticide with high efficiency, broad spectrum and low toxicity developed by Kesheng Group. It is mainly used to control Homopteran pests. At present, imidacloprid is one of the most widely used insecticides in the world, but due to its large and frequent use, it has caused significant resistance worldwide, and the activity of picloprid against resistant sap-sucking pests is significantly higher than that of imidacloprid. Therefore, picloprid is one of the ideal varieties to replace imidacloprid to control planthoppers and aphids. The chemical name of piperacridin is: 1-((6-chloropyridin-3-yl)methyl)-5-propoxy-7-methyl-8-nitro-1,2,3,5,6,...
