Plant-virus resisting composition and plant-virus resisting medicament as well as application of plant-virus resisting medicament

Abstract

The invention relates to a plant-virus resisting composition which contains active constituents. The plant-virus resisting composition is characterized in that the active constituents contain amino-oligosaccharins and ribavirin; the weight ratio of the amino-oligosaccharins to the ribavirin is 1: (0.03-20). The invention also relates to a plant-virus resisting medicament prepared from the plant-virus resisting composition. The dosage form of the plant-virus resisting medicament can be soluble liquid, soluble powder, water dispersible granules, granules or water aqua. The invention also relates to an application of the plant-virus resisting medicament in prevention and treatment of one or multiple plant viruses comprising tobacco mosaic viruses, cucumber mosaic viruses, potato Y viruses, tomato mosaic viruses, tomato yellow leaf curl viruses and tomato spotted wilf viruses. The plant-virus resisting composition and the plant-virus resisting medicament are good in prevention and treatment effects, and therefore, the medicament using amount can be reduced, the cost is reduced, and the pollution to the environment is relieved; the plant-virus resisting medicament does not only contain a single active constituent, so that the plant viruses difficultly produce drug resistance; the plant-virus resisting medicament can prevent and treat various different types of plant-virus diseases.

Description

technical field [0001] The present invention relates to an anti-plant virus composition, an anti-plant virus agent and applications thereof, in particular to an anti-plant virus composition containing amino oligosaccharin and ribavirin, and the anti-plant virus composition The prepared anti-plant virus agent and the application of the anti-plant virus agent in preventing and treating plant viruses. Background technique [0002] Plant virus disease is a disease caused by plant virus parasitism. Plant viruses must live parasitic in host cells and are highly specialized. A certain virus can only infect a certain type or certain plants, but there are also a few that do extensive damage, such as tobacco mosaic virus and cucumber mosaic virus. Generally, plant viruses are only active in the living body of the host. [0003] In addition to taking part of the nutrition of the infected plant, plant viruses replicate nucleic acid (RNA or DNA) and protein coats in host cells to form ...

AI Technical Summary

Problems solved by technology

[0004] There are many kinds of plant viruses, such as tobacco mosaic virus, cucumber mosaic virus, potato Y virus, tomato mosaic virus, tomato yellow leaf curl virus, tomato spotted wilt virus, etc., which have a wide range of damage and are difficult to control. Practical and effective agents are mainly based on comprehensive prevention and control measures such as selection of anti-virus varieties, strengthening cultivation management, and seed disinfection.

Once infested, it is difficult to control with pesticides
