Embodiment 1

[0022] A composition for preventing and treating gray mold of kiwifruit, comprising the following components: difenoconazole, umbelliferone and graphene oxide, wherein the mass percentages of the three components mixed are shown in Table 1.

[0023] Table 1 The mass percentages of the three components mixed

[0024]

Embodiment 2

[0026] Indoor toxicity assay of composition described in table 1, the process of test is as follows:

[0027] Test object: kiwifruit botrytis cinerea wild strain (Botrytis cinerea).

[0028] 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.

[0029] The growth rate method was used to measure the inhibitory rate of compositions 1 to 8 against wild strains of kiwifruit 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.

[0030] Table 2 Composition 1~8 is to the inhibitory rate result of kiwi fruit gray mold wild strain

Embodiment 3

[0044] Compositions 2-8 are used as active ingredients, which can be processed into suitable dosage forms for use according to the control environment and use requirements of kiwifruit gray mold. Among them, the commonly used suitable dosage forms are wettable powder, water-dispersible granule, suspension concentrate, and emulsifiable concentrate or granules.

[0045] 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.

[0046] 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%.

[0047] When processed into a su...

Abstract

The invention discloses a composition for prevention and control of actinidia chinensis gray mold and a fungicide prepared therefrom. The composition comprises the following components by mass percentage: 40%-80% of difenoconazole, 15%-50% of umbelliferone, and 1%-15% of graphene oxide. According to the composition for prevention and control of actinidia chinensis gray mold provided by the invention, difenoconazole, the plant extract umbelliferone and graphene oxide are compounded, within a specific proportion range, the three components play a synergistic role cooperatively, while the dosageof difenoconazole is lowered, good inhibitory activity of the composition on strawberry gray mold can be guaranteed, and the inhibiting effect is equivalent to that of the single agent difenoconazole.The mixed composition can be prepared into a fungicide for use, and the fungicide can effectively prevent and control actinidia chinensis gray mold, at the same time can reduce the dosage of difenoconazole, and slow down and / or prevent the actinidia chinensis gray mold pathogens from producing resistance to difenoconazole.

Description

technical field [0001] The invention relates to the technical field of preventing and treating kiwifruit gray mold, and more particularly relates to a composition for preventing and treating kiwifruit gray mold and a fungicide prepared therefrom. Background technique [0002] Kiwi (Actinidia chinensis), because it contains a high content of vitamin C, and has a sweet and sour taste and a good flavor, is very popular as a health-care fruit. In recent years, due to the expansion of kiwifruit production scale year by year, kiwifruit gray mold has become increasingly serious. When the kiwi fruit is damaged, it often turns brown and rots from the fruit pedicle, and gradually expands to the navel to cause the disease of the whole fruit. White to gray mold layers often appear on the surface of the diseased fruit, and sometimes black irregular sclerotia can be seen. At present, biological control and botanical pesticides have not been promoted in the prevention and control of kiwif...
