Abstract

The invention provides a composition for preventing and treating plant virus diseases as well as a preparation method and application thereof. The composition comprises the following raw materials: aresistance inducer; a surfactant; sodium alginate and a brassinolide compound; wherein the resistance inducer is at least one of lentinan, chitosan and amino-oligosaccharin; wherein the surfactant isat least one of perfluorohexylethyl methyl dimethoxy silane, (3, 3, 3-trifluoropropyl) dichloromethylsilane and trifluoropropyl methyl cyclotrisiloxane. The composition provided by the invention can induce and enhance plant immunity so as to inhibit virus infection; meanwhile, the surfactant has good compatibility and binding capacity with other raw materials; when the composition is sprayed to plants, a film can be rapidly formed on the surfaces of the plants, the firmness of the film can be improved through mutual combination of the sodium alginate and the surfactant, and even if it rains after spraying, the composition cannot be completely scoured by rainwater, so that the pesticide effect retention time is long, and the pesticide application frequency can be reduced.

Description

technical field [0001] The invention relates to the technical field of plant virus disease resistance, in particular to a composition for preventing and treating plant virus diseases, a preparation method and application thereof. Background technique [0002] Chrysanthemum is a perennial herbaceous plant of Compositae and Chrysanthemum. It not only has the same source of medicine and food, but also has a very high ornamental value. It is one of the top ten famous flowers in China and one of the four major cut flowers in the world. According to incomplete statistics, in 2016, my country's domestic chrysanthemum production was 2.693 billion, and in 2017, my country's chrysanthemum production was 2.784 billion, with a year-on-year increase of 3.37% and an increasing trend year by year. [0003] However, due to the long-term use of asexual reproduction methods such as split roots and cuttings in the production of chrysanthemums, the plants are seriously infected with viruses, th...
