Pesticide composition capable of preventing and treating plant virus diseases and application of pesticide composition

Abstract

The invention relates to a pesticide composition capable of preventing and treating plant virus diseases and application of the pesticide composition, belongs to the pesticide compositions, and aims at providing a pesticide composition capable of preventing and treating plant virus diseases. The active components of the pesticide composition capable of preventing and treating plant virus diseases comprises lentinan and emodin monomethyl ether according to a weight ratio of (1-100) to (0.1-500). Furthermore, the invention also discloses application of the pesticide composition capable of preventing and treating plant virus diseases in prevention and treatment of plant virus diseases. According to the pesticide composition capable of preventing and treating plant virus diseases, lentinan and emodin monomethyl ether are compounded and used as active components; the components are environmentally friendly; the pollution to the environment is avoided; meanwhile, lentinan and emodin monomethyl ether have synergetic effects, have a good effect of preventing and treating the plant virus diseases and are capable of inducing and enhancing plant immunity, so that the infection of the virus can be inhibited; the effects of resisting virus and increasing yield can be achieved.

Description

technical field [0001] The invention relates to a pesticide composition for preventing and treating plant virus diseases and an application thereof, which belongs to the pesticide composition. Background technique [0002] Plant virus disease is a disease caused by plant virus parasitism. Plant viruses must live parasitic lives in host cells, and are highly specialized. A certain virus can only infect a certain type or certain plants. Common plant virus diseases with widespread damage include tobacco mosaic virus and cucumber mosaic virus. [0003] Generally, plant viruses are active only in the living body of the host; only a few plant viruses can remain active in the residue of diseased plants for several days, months, or even years, and a few plant viruses can survive or multiply in the living body of insects. Plant viruses replicate nucleic acid (RNA or DNA) and protein coats in host cells to form new virions. The transfer speed of plant virions or viral nucleic acid ...
