Problems solved by technology

[0003] In order to effectively control plant virus diseases, people try to take various comprehensive control measures, such as planting disease-resistant and resistant varieties, selecting non-toxic seeds and seed disinfection, promoting virus-free seedling technology, strengthening field management, planting in protected areas, and preventing and controlling virus-transmitting agents. However, it is still necessary to develop high-efficiency and low-cost green antiviral pesticides.

Abstract

The invention discloses a pesticide composite for preventing and controlling a plant virus disease, belongs to the technical field of pesticides, and solves the problems that the application dose of the current pesticide is large and the pesticide effect is not obvious. The pesticide composite comprises Dufulin and cytosintetidemycin, and is specifically prepared from the following raw materials in percentage by weight: 8-40 percent of dufulin, 1-15 percent of cytosintetidemycin, 10-25 percent of addition agent, 5-15 percent of solvent and 5-76 percent of water. The two effective components of the pesticide composite have synergism, have prevention and protection effects, and can effectively prevent and control the plant virus disease.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide composition for preventing and treating plant virus diseases and the application thereof. The active ingredients are hexafluorophos and pyrimpeptidemycin, and the two have synergistic effects. Background technique [0002] Plant virus disease is a disease caused by plant virus parasitism, which often causes heavy losses to agricultural production. This kind of disease is also a kind of disease that is very difficult to control in plant diseases. It is often called "plant cancer" because of its many types, wide distribution, serious damage, and difficult to control. In recent years, the viral diseases of various crops such as vegetables and grains have shown a trend of increasing year by year. In addition to the traditional tobacco mosaic disease, cucumber mosaic disease, tomato, and pepper virus diseases that commonly occur on vegetables, whitefly-transmit...
