Problems solved by technology

Practice has proved that the control effect of these plant virus control agents is still unsatisfactory. In particular, there are few types of plant virus disease control agents currently registered, which are far from meeting the needs of production to prevent and control virus diseases.

Abstract

The invention discloses an application of eugenol used as a main active component in preparing pesticide preventing and treating crop virosis. The experiment research shows that the eugenol provided by the invention has a very good preventing and treating function to the virosis of various crops and has wide antivirus spectra, the effective component of the eugenol of the invention is a natural, green and environment-friendly active component extracted and obtained from traditional Chinese medicines, has the preventing and treating function to the crop virosis and does not pollute the environment, and the invention takes the eugenol as the main active component to prepare pesticide with medicament forms, such as eugenol soluble liquid or eugenol microemulsion and the like, and has convenient use and storage and good stability.

Description

technical field [0001] The invention relates to eugenol, in particular to the application of eugenol in the preparation of pesticides for preventing and treating crop virus diseases. Background technique [0002] Plant virus disease is a kind of important disease with various types, widespread occurrence and serious damage in agricultural production. It is called "plant cancer", and this disease is the second largest type of plant disease after fungi. According to statistics, there are more than 900 types of plant viruses discovered in the world at present, and more than 100 types have been reported in my country. Virus diseases cause serious losses to crop production around the world every year. In my country, the annual losses caused by plant viruses are incalculable, and the virus diseases of many major crops have spread to the main production areas of the country. For example, in the 1970s and 1980s, wheat bush dwarf disease and soil-borne mosaic disease were prevalent ...
