The active ingredients of the pharmaceutical composition for preventing and treating the peanut stripe virus disease are brassinolide and ningnanmycin; the concentration ratio of brassinolide to ningnanmycin in the medicinal composition is 0.1-0.3: 80. The brassinolide and ningnanmycin compound in the pharmaceutical composition has better prevention effect on PStV than that of a single agent, and has obvious promotion effect on growth and yield of peanuts.)

1. A pharmaceutical composition for preventing and treating peanut stripe virus disease is characterized in that the active ingredients are brassinolide and ningnanmycin; the concentration ratio of brassinolide to ningnanmycin in the medicinal composition is 0.1-0.3: 80.

2. The pharmaceutical composition for preventing and treating peanut stripe virus disease as claimed in claim 1, wherein the concentration ratio of brassinolide to ningnanmycin in the pharmaceutical composition is 0.3: 80.

3. The use of the pharmaceutical composition of claim 1 or 2 for preventing and treating peanut stripe virus disease, promoting peanut growth, and increasing peanut yield.

4. A method for simultaneously preventing and treating peanut stripe virus diseases, promoting peanut growth and improving peanut yield is characterized in that the pharmaceutical composition of claim 1 or 2 is diluted by water until the concentration of brassinolide is 0.1-0.3 mg/L and the concentration of ningnanmycin is 80 mg/L, and the pharmaceutical composition is uniformly sprayed on peanut plants.

Technical Field

The invention belongs to the technical field of pesticide compounding, and particularly relates to a pharmaceutical composition for preventing and treating peanut stripe virus diseases and application thereof.

Background

Peanut Stripe virus (PStV) is widely prevalent in Peanut producing areas in China, is the most serious in northern planting areas, and has the most serious influence on the Peanut industry in China in virus diseases. The popular years are in Hebei and Beijing in North China, Henan in China, Shaanxi in northwest China, Liaoning in northeast China, peanut planting areas in Shandong, Anhui, Jiangsu and other provinces (cities) in east China, the common planting areas have more than 50 percent of peanut plants, and some plots or even all plots have diseases, so that the yield reduction of peanuts is serious and the quality is reduced. The prevention and treatment of peanut stripe virus mostly adopts a method of planting disease-resistant varieties, and effective prevention and treatment measures are lacked. At present, the natural product antiviral preparation has more researches on resisting virus diseases of solanaceae crops, but reports on application of the natural product antiviral preparation to peanut virus diseases are not found.

Disclosure of Invention

Aiming at the problems in the prior art, the invention aims to provide a pharmaceutical composition for preventing and treating peanut stripe virus diseases and application thereof.

In order to achieve the purpose, the invention adopts the following technical scheme:

a pharmaceutical composition for preventing and treating peanut stripe virus disease contains brassinolide and ningnanmycin as effective components; the concentration ratio of brassinolide to ningnanmycin in the medicinal composition is 0.1-0.3: 80.

On the basis of the scheme, the concentration ratio of the brassinolide to the ningnanmycin in the pharmaceutical composition is 0.3: 80.

The pharmaceutical composition is applied to preventing and treating peanut stripe virus diseases, promoting peanut growth and improving peanut yield.

A method for simultaneously preventing and treating peanut stripe virus diseases, promoting peanut growth and improving peanut yield is characterized in that the pharmaceutical composition is diluted by adding water until the concentration of brassinolide is 0.1-0.3 mg/L and the concentration of ningnanmycin is 80 mg/L, and the pharmaceutical composition is uniformly sprayed on peanut plants.

The technical scheme of the invention has the advantages

The PStV control effect (45.0%) of the combination of Brassinolide and Ningnanmycin in the pharmaceutical composition for preventing and treating peanut stripe virus diseases is higher than that of the combination of single-dose Brassinolide (36.1%) and Ningnanmycin (34.5%), the promotion effect on peanut growth and yield is obvious, and the improvement of the flower yield (35.6%) of the combination of the Brassinolide and the Ningnanmycin (21.2%) is better than that of the combination of single-dose Brassinolide (13.8%) and the Ningnanmycin.

Detailed Description

Terms used in the present invention have generally meanings as commonly understood by one of ordinary skill in the art, unless otherwise specified.

The present invention will be described in further detail with reference to the following data, with reference to specific examples. The following examples are intended to illustrate the invention and are not intended to limit the scope of the invention in any way.
