Embodiment 1

[0025] Embodiment 1: the preparation of 1% Corilagin microemulsion

[0026] Weigh 1kg of Corilagin, dissolve it in 30kg of ethyl acetate, then add 15kg of calcium dodecylbenzenesulfonate and 5kg of styrene acid polyoxyethylene ether, mix under high-speed stirring, and heat to about 40°C; high-speed stirring Add deionized water dropwise to make up to 100kg. During the process of dropping deionized water, keep the temperature at about 40°C; after adding water dropwise, raise the temperature to 50°C and stir for 1 hour to prepare 1% Corilagin microemulsion 100kg. The stability and appearance of the preparation meet the requirements of commercial preparations.

Embodiment 2

[0027] Embodiment 2: the preparation of 30% Corilagin microemulsion

[0028] Weigh 30kg of Corilagin, dissolve it in 30kg of ethyl acetate, then add 15kg of calcium dodecylbenzenesulfonate and 5kg of styrene acid polyoxyethylene ether, mix under high-speed stirring, and heat to about 40°C; high-speed stirring Add deionized water dropwise to make up to 100kg, and keep the temperature at about 40°C during the dropwise addition of deionized water; after the water is added dropwise, heat up to 50°C and stir for 1 hour to prepare 100kg of 30% Corilagin microemulsion . The stability and appearance of the preparation meet the requirements of commercial preparations.

Embodiment 3

[0029] Embodiment 3: the preparation of 1% Corylaginko solution

[0030] Weigh 1 kg of Corilagin, dissolve it in 30 kg of ethyl acetate, then add 15 kg of calcium dodecylbenzenesulfonate, 5 kg of styrene acid polyoxyethylene ether, and make up to 100 kg with ethanol. After mixing evenly, stir at a speed of 800 100 kg of 1% Corylaginko solution can be prepared by stirring at ~1000 rev / min for 10-30 minutes. The stability and appearance of the preparation meet the requirements of commercial preparations.

Abstract

The invention discloses a plant virus resistant agent. The effective constituent of the prepared plant virus resistant agent is corilagin, and auxiliaries are assisted to prepare soluble concentrate, aqueous solution and microemulsion. The plant virus resistant agent is harmless to human, livestock, natural enemies of pests and other beneficial organisms, has good environment compatibility, has no residual hazard after use, has abundant resources, simple preparation method and low cost, and can be used for preventing plant virus diseases such as tobacco mosaic virus, cucumber mosaic virus and potato virus on tobacco, chili, tomato, cucurbita pepo, potato and other crops.

Description

technical field [0001] The invention belongs to the field of plants and applications thereof, in particular to an anti-plant virus agent containing corilagin and its application. Background technique [0002] Plant virus is an intracellular parasitic pathogen composed of nucleic acid and protein with infectious activity. According to the eighth report of the International Committee on Taxonomy of Viruses (ICTV), there are currently 1122 plant virus species found in the world. Phytopathogens caused by plant viruses are known as "plant cancers", and their damage to crops is second only to fungal pathogens. Almost every crop is harmed by 2 to 3 viruses. The annual loss caused by plant viruses in the world is about 40 billion U.S. dollars, and the damage caused by tobacco mosaic virus (TMV) alone exceeds 100 million U.S. dollars. [0003] Since plant viruses are absolutely parasitic to plant cells, the material and energy sites required for virus replication are completely prov...
