Problems solved by technology

Such as lentinan and brassinolide (patent name: an antiviral composition containing lentinan and brassinolide and its application, patent application number: 201110027898.4), lentinan and sodium sulfate (patent name: a Antiviral composition containing lentinan, patent application number: 200910018517.2), lentinan and morpholine hydrochloride (patent name: a combined pesticide for preventing and treating tobacco virus disease, patent application number: 201010294324.2) and other patents, but the lentinan The combination of polysaccharide and Compound A has not been found to be used in tobacco antiviral applications. Compound A belongs to the natural product hamateline and dehydrohaeline compounds, which can induce disease resistance in crops and inhibit viruses. The role of infection, compounded with lentinan to achieve anti-virus, increase yield and improve quality

Embodiment 1

[0024] Preparation of 5.5% lentinan compound A aqueous solution:

[0025] Raw materials are proportioned by weight percentage: lentinan: 0.5%, compound A: 5.0%, Tween 80: 8%, 31% hydrochloric acid: 2.0%, potassium dihydrogen phosphate: 5%, water: make up to 100%. The process steps are as follows: first mix and dissolve the lentinan and water, then add compound A, hydrochloric acid, tween temperature and potassium dihydrogen phosphate successively under the condition of stirring, and the finished product is obtained after the potassium dihydrogen phosphate is completely dissolved.

Embodiment 2

[0027] Preparation of 9% lentinan compound A aqueous solution:

[0028] Raw materials are proportioned by weight percentage: lentinan: 1.0%, compound A: 8.0%, Tween 80: 10%, 31% hydrochloric acid: 3.0%, potassium dihydrogen phosphate: 5%, water: make up to 100%. The preparation method is the same as in Example 1.

Embodiment 3

[0030] Preparation of 2.5% lentinan compound A aqueous solution:

[0031] The raw materials are proportioned by weight: lentinan: 0.5%, compound A: 2.0%, Tween 80: 10%, 31% hydrochloric acid: 1.0%, potassium dihydrogen phosphate: 5%, water: make up to 100%. The preparation method is the same as in Example 1.

Abstract

The invention discloses an anti-plant virus disease composition containing lentinan. The main effective components comprise lentinan and a compound A with an acylhydrazone structure or a salt of the compound A The pesticide composition disclosed by the invention is mainly used for preventing and treating various crop viruses, such as tobacco mosaic virus disease, tomato mosaic virus disease, corndwarf mosaic virus disease, rice leaf blight disease and the like, inducing the disease resistance of crops, inhibiting infection of viruses, and has the effects of resisting viruses, increasing yields and improving qualities.

Description

technical field [0001] The invention belongs to the field of plant anti-viral diseases, and in particular relates to a plant anti-viral disease composition containing lentinan. Background technique [0002] Compound A containing an acylhydrazone structure is a pesticide active ingredient, and its chemical name is: (1S,3S)-N-(4-chlorophenylmethylene)-1-methyl-2,3,4,9 -Tetrahydropyrido[3,4-b]indole-3-carbohydrazide. The compound A containing an acylhydrazone structure has very good biological activity against tobacco mosaic virus, tomato mosaic virus, etc., and at the same time, this type of compound is easily absorbed by plants, easy to degrade in the environment, and has good environmental compatibility. [0003] Compound A structural formula: [0004] [0005] Lentinan (English name: lentinan), lentinan is an effective active ingredient extracted from high-quality mushroom fruiting bodies. The main components of mushrooms are polysaccharides and unsaturated fatty acids...
