Embodiment 1

[0023] A composition for preventing and treating ginseng botrytis, comprising the following components: difenoconazole, umbelliferone and graphene oxide, wherein the mass percentages of the three components mixed are shown in Table 1.

[0024] Table 1 The mass percentages of the three components mixed

[0025]

Embodiment 2

[0027] Indoor toxicity assay of composition described in table 1, the process of test is as follows:

[0028] Test object: wild strain of ginseng gray mold (Botrytis cinerea).

[0029] The preparation method of compositions 1 to 8 in Table 1 is as follows: weigh 3 components according to Table 1, then dissolve the 3 components in the ethanol solution, then slowly mix the 3 ethanol solutions while stirring, After mixing and stirring for more than 3 hours, the mother liquor can be prepared and set aside.

[0030] The growth rate method was used to measure the inhibitory rate of compositions 1 to 8 on wild strains of ginseng botrytis cinerea, and a group of blank control groups CK were set up, with single doses of difenoconazole, umbelliferone, and graphene oxide as For comparison, the results are shown in Table 2.

[0031] Table 2 Compositions 1 to 8 are the results of the inhibitory rate of wild strains of Botrytis ginseng

[0032]

[0033] It can be seen from Table 2 tha...

Embodiment 3

[0045] Compositions 1 to 6 are used as active ingredients, which can be processed into suitable dosage forms for use according to the control environment and use requirements of ginseng gray mold. Among them, the commonly used suitable dosage forms are wettable powder, water dispersible granule, suspension concentrate, emulsifiable concentrate or granules.

[0046] Among them, when processed into wettable powder, the mass percentage of each raw material is: 10% to 50% of any composition in the above compositions 1 to 8, 1% to 8% of the dispersant, and 1% to 8% of the wetting agent. 2% to 8%, and then make up to 100% with filler.

[0047]When processed into water-dispersible granules, the mass percentage of each raw material is: 10%-80% of any composition in the above-mentioned compositions 1-8, 1%-8% of the dispersant, and 2% of the wetting agent. % to 8%, the binder is 0.5% to 5%, the disintegrant is 0.2% to 5%, and then filled to 100%.

[0048] When processed into a suspen...

Abstract

The invention discloses a composition for preventing and controlling the gray mold of ginseng and a bactericide prepared by the composition. The composition comprises the following components in percentages by weight: 40% to 70% of difenoconazole, 20% to 50% of umbelliferone and 0.1% to 15% of oxidized graphene. According to the composition for preventing and controlling the gray mold of ginseng disclosed by the invention, difenoconazole, plant extract difenoconazole and oxidized graphene are blended, within a specific proportional region, a synergistic effect is developed among the three components mutually, the blended composition has extremely high inhibitory activity for the gray mold of ginseng while the using amount of difenoconazole is reduced, and the inhibiting effect is equivalent to that of single-dose difenoconazole. The blended composition is used after being prepared into the bactericide, the gray mold of ginseng can be prevented and controlled effectively, simultaneouslythe using amount of difenoconazole also can be reduced, and the resistance of pathogenic bacteria of the gray mold of ginseng for difenoconazole is retarded and / or prevented.

Description

technical field [0001] The invention relates to the technical field of preventing and treating ginseng gray mold, and more particularly relates to a composition for preventing and treating ginseng gray mold and a fungicide prepared therefrom. Background technique [0002] Ginseng has a variety of pharmacological effects and is widely used in the treatment and health care of various diseases. It is a traditional and precious Chinese medicinal material in my country. It has been cultivated for more than 1,600 years and has been cultivated on a large scale for more than 400 years. On the one hand, due to long-term artificial cultivation and domestication, the ability of ginseng to resist various plant pathogenic bacteria has declined; Strong; therefore, ginseng is vulnerable to the invasion of various pathogenic bacteria during the planting process, which in turn leads to the occurrence of various diseases. In recent years, ginseng botrytis has become more and more serious, an...
