Embodiment 1

[0022] Put the pulverized tung tree seed oil cake with a particle size of 10 mesh into the reactor, use ethanol as the extraction solvent, add it to the material according to the weight ratio of material:solvent=1:2, and extract it under the condition that the extraction temperature is 50°C. After 30 minutes, the solid-liquid separation was carried out, and the extract of the tung tree seed oil cake was obtained after precipitation. Add matrine, production-increasing amine, water, tung tree seed oil cake extract, and fatty alcohol polyoxyethylene ether into the reaction kettle, control the dissolution temperature at 50°C, and stir and dissolve for 20 minutes; add zinc fulvic acid to the reaction kettle In the kettle, control the dispersion temperature to 50°C, and stir and disperse for 20 minutes; after cooling, the anti-plant virus agent is prepared. The raw materials used and the weight ratio of the prepared anti-plant virus agent are:

Embodiment 3

[0117] Put the pulverized tung tree seed oil cake with a particle size of 30 mesh into the reaction kettle, adopt ethanol as the extraction solvent, add it to the material according to the weight ratio of material:solvent=1:10, and extract it under the condition that the extraction temperature is 70°C. After 80 minutes, the solid and liquid were separated, and the oil cake extract of Tung tree seeds was obtained after precipitation. Add sophocarpine, abscisic acid, ethanol, tung tree seed oil cake extract, and sodium dodecylbenzenesulfonate into the reaction kettle, control the dissolution temperature at 65°C, and stir and dissolve for 55 minutes; add manganese fulvic acid Put it into a reaction kettle, control the dispersion temperature to 60°C, and stir and disperse for 55 minutes; after cooling, the anti-plant virus agent is obtained. The raw materials used and the weight ratio of the prepared anti-plant virus agent are:

Abstract

The invention discloses an anti-plant virus agent and a preparation method and application thereof. The anti-plant virus agent of the invention comprises the following components in parts by weight: 10-50 parts of jatropha curcas seed oil cake extract, 10-50 parts of alkaloid, 10-50 parts of fulvic acid salt, 5-50 parts of plant growth regulator, 10-60 parts of surfactant and 20-75 parts of solvent. The preparation method mainly comprises the following steps: respectively heating and dissolving the alkaloid, the plant growth regulator, the solvent, the jatropha curcas seed oil cake extract and the surfactant; adding, heating and dispersing the fulvic acid salt; and obtaining the anti-plant virus agent after cooling. The invention can solve the defects of single mode of action on the plant virus and low controlling effect of the current products. The product of the invention has the advantages of reduction of virus diseases transmitted by aphids, good therapeutic effect on plant virus diseases, obviously improvement of the disease-resisting capacity of plants, and good wettability, spreading property and permeability, low use cost and simple production processes.

Description

technical field [0001] The invention relates to an anti-plant virus agent, in particular to a high-efficiency, low-cost plant-derived anti-plant virus agent and its preparation method and application. Background technique [0002] Plant virus diseases have become the second largest type of plant diseases after plant fungal diseases. Because viruses are absolutely parasitic in plant cells, the materials, energy and places required for their replication are completely dependent on the host, and plants do not have a complete immune metabolism system, making it difficult to prevent and control plant virus diseases, causing huge economic losses to agricultural production The annual loss caused by plant viruses in the world is about 20 billion U.S. dollars, and the global annual loss caused by tobacco mosaic virus alone reaches more than 100 million U.S. dollars. [0003] In order to effectively control the harm of plant viruses, in addition to traditional anti-virus breeding, cr...
