experiment example 1

[0022] In this experiment, dipropetamiprid and acetamiprid were used as the test agents, and the toxicity of the leaf film method was used to determine the toxicity of the single agent and the mixture of various proportions. The LC was calculated. 50 , co-toxicity coefficient (CTC) and optimal ratio.

[0023] 1. Research object

[0024] Laboratory-reared multigenerational field populations of cotton aphids. The field population of cotton aphids was collected from cotton fields in Xinjiang, and non-transgenic cotton seedlings were cultivated indoors for multiple generations.

[0025] 2. Method

[0026] For the test agents dipropetamiprid and acetamiprid, the indoor toxicity test was carried out by using the leaf drug film method, including the single-dose toxicity test of dipropetamiprid and acetamiprid; Toxicity determination of mixtures of various proportions. Calculate the virulence assay results and calculate the LC 50 , Co-toxicity coefficient (CTC) to get the best ra...

Abstract

The invention relates to an afidopyropen and acetamiprid compound synergistic pesticide and application thereof. The active ingredients of the compound pesticide capable of effectively preventing andtreating cotton aphid comprise afidopyropen and acetamiprid with the mass ratio being (1-20):(1-20). In order to solve the technical problem of drug resistance of the cotton aphid, compounding of afidopyropen and acetamiprid are discovered to be capable of effectively delaying generation of the drug resistance of the cotton aphid and have the synergistic effect on prevention and treatment of the cotton aphid on the basis of a large amount of indoor toxicity screening, and a new effective prevention and treatment means is provided for inset pest comprehensive control of the cotton aphid. The effect-enhancing pesticide lowers the using amount of farm chemicals, accordingly reduces the cost and the pollution to the environment, is beneficial for resistance control of the cotton aphid, and hasthe great economic benefits and social benefits when being popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a compound synergistic insecticide of dipropacyclotran and acetamiprid and an application thereof. Background technique [0002] Cotton aphids (Aphis gossypii) is an important pest worldwide, which can feed on more than 700 kinds of plants including cotton and cucumber. Cotton aphids cause harm mainly by directly feeding on plant sap and spreading plant viruses, causing huge economic losses to agricultural production. Cotton aphid has the characteristics of fast reproduction, large population, and severe damage. For a long time, chemical control has been the main means of control of cotton aphid in my country. Due to the long-term and extensive use of chemical pesticides, cotton aphids have developed high levels of resistance to various insecticides such as organophosphates, carbamates, pyrethroids, and neonicotinoids. [0003] Long-term use of pesticides will le...
