Abstract

The invention discloses an insecticidal composition containing propylene glycol alginate and carbamates, in particular to an insecticidal composition comprising an active component A and an active component B. The active component A is selected from the propylene glycol alginate, the active component B is selected from one of the following compounds: isoprocarb, tsumacide, indoxacarb, carbaryl, methomyl and fenobucarb, and the weight ratio of the active component A to the active component B is 1: 80 to 40: 1. The composition has synergism on multiple injurious insects which are harmful to the agricultural production, the consumption of farm chemicals can be reduced, the residue of the farm chemicals on crops can be reduced, the environmental pollution can be reduced, safety for the human beings and animals can be realized, the environmental compatibility is good, and the drug resistance of the injurious insect is difficult to generate.

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 carbamates 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] Carbamate insecticides mainly block sodium channels in pest nerve cells, resulting in poor coordination, paralysis, and eventual death of target pests. The pesticide enters the insect body through contact killing and ingestion, and the behavior of the pest changes rapidly, causing the pest to stop feeding quickly, thus excellently protecting the target crop. Tests have shown no cross-resistance with other insecticides. [0004] However, in the actual process of agricultural production, the most likely problem in pest control is ...
