Problems solved by technology

However, the systemic property of butene fipronil is poor, the insecticidal spectrum is not wide, and the cost is high, which greatly limits the promotion and use of this insecticide.
[0007] At present, the compounding and application of nitenpyram and butylene-fipronil has not yet appeared, nor has it been reported in domestic and foreign literature

Abstract

The invention relates to a desinsection composite and application thereof. The effective components are Nitenpyram and crotonylfipronil; the weight portion ratio of the Nitenpyram to the crotonylfipronil is 20:1-1:20. The desinsection composite can be processed into any preparation formulation acceptable to pesticide application; the preferable preparation formulation is wettable powder, aqueous emulsion, missible oil, microemulsion, water dispersible granule or troche, and suspending agent. The disinsection composite is used for controlling pests on plants, especially for controlling the homoptera pests which generate resistance like plant hopper, leafhopper, white fly, and the like.

Description

technical field [0001] The invention relates to an insecticide composition and an application thereof, in particular to an insecticide composition with nitenpyram and butene-fipronil as active components and an application thereof. Background technique [0002] At present, environmental issues have become the focus of people's attention, and countries around the world have stricter requirements on the toxicity of pesticides and their impact on the environment. Many high-efficiency and low-toxic varieties developed in recent years are gradually replacing organophosphorus pesticides with long residual time and serious pollution. [0003] Homoptera insects all feed on plant sap, many of which can spread plant virus diseases and are important agricultural pests, such as cabbage aphid, bean aphid, cotton aphid, rice planthopper and whitefly. Homopteran pests are small in size, strong in fecundity, and have many generations. They are easy to develop resistance to control chemical...
