Abstract

The invention discloses an insecticide composition containing propylene glycol alginate and anabasine. The insecticide composition comprises an active component A and an active component B. The active component A is propylene glycol alginate; the active component B is one compound optionally selected from thiamethoxam, thiacloprid, clothianidin and dinotefuran ; and the weight ratio of the active component A to the active component B is 1:80-60:1. The insecticide composition possesses synergistic effect on a plurality of insects which are capable of causing harm to agricultural production; is capable of reducing insecticide dosage, insecticide residue on crops, and environmental pollution; is safe for people and livestock; and possesses excellent environmental compatibility. In addition, drug resistance of insects is difficult to be caused by the insecticide composition containing propylene glycol alginate and anabasine.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of an insecticidal composition containing propylene glycol alginate and neonicotinoids on crop pests. Background technique [0002] Propylene glycol alginate molecular formula: (C 9 h 14 o 7 )n, which is an emulsified suspension made from seaweed extract through an emulsification process, has contact killing activity on insects. [0003] Neonicotinoid insecticides are new types of high-efficiency and low-toxicity insecticides successfully developed on the basis of the research on the structure of nicotine, and are regarded as another major breakthrough in the history of insecticide synthesis since pyrethroids Neonicotinoid insecticides are nicotinic acetylcholine receptor (nAChR) agonists (agonists), which have selective toxic effects on insects. As effective agents for integrated pest management, they are increasingly used at home and abroad. widely. [000...
