Problems solved by technology

[0003] 1. The powder has relatively large dust in the production process, which pollutes the environment seriously
[0004] 2. The main organic solvent of emulsifiable concentrate contains a large amount of xylene, toluene, etc. As the price of oil continues to rise, the price of organic solvents also rises, which virtually increases the cost of farmers' medicines
[0005] 3. Due to the use of organic solvents, the emulsifiable concentrate is prone to phytotoxicity in the process of use, and there are also great difficulties in the process of storage, transportation and production
[0006] 4. Due to the large and excessive use of emulsifiable concentrate, the residue of crops is relatively large, and it is not uncommon for examples of returns due to residue problems during export.
At present, few people carry out prevention and treatment. It is a new drug preparation.

Abstract

The present invention discloses an agricultural composition for killing acarus, specifically a compound composition containing propargite and fenisobromolate. The invention is characterized in that the active components of propargite and fenisobromolate in terms of percentage by weight is 1-60 : 0.1:50, and the composition can be prepared into aqueous emulsion by adding proper amount of additive agents or carriers for preventing and controlling red spider lived in orange.

Description

Technical field: [0001] The invention belongs to the technical field of pesticides, and in particular relates to a water-emulsion with acaricidal effect containing a combination of propargid and bromofen. technical background: [0002] Since the main formulations of acaricides for the prevention and control of red spider mite are mainly powders and emulsifiable concentrates, but we know that the disadvantages of powders and emulsifiable concentrates are mainly manifested in the following points: [0003] 1. In the production process of powder, there is relatively large dust, which seriously pollutes the environment. [0004] 2. The main organic solvent of emulsifiable concentrate contains a large amount of xylene, toluene, etc. As the price of oil continues to rise, the price of organic solvents also rises, which virtually increases the cost of farmers' medicines. [0005] 3. Due to the use of organic solvents, the emulsifiable concentrate is very prone to phytotoxicity in ...
