Embodiment 1

[0012] Example 1: Compound 3', 4'-diacetylkhelactone prevents and treats agricultural diseases

[0013] The tested strain S. sclerotiorum ( Sclerotioia selerotiorum ) is isolated from Sclerotinia sclerotiorum strain; Rhizoctonia solani ( Thanatephorus cucumeris) It is isolated from rice sheath blight diseased leaves; Botrytis cinerea, also known as Botrytis cinerea, is isolated from strawberry gray mold.

[0014] The test compound 3',4'-diacetylkhellactone was dissolved in methanol to make a 1000 μg / mL mother solution, and stored at 4°C for later use. PDA medium: Cut 200g of peeled potatoes into pieces, boil for 10min, take the juice, add 20g of agar, heat until melted, then add 20g of glucose, and dilute to 1000mL with water.

[0015] The inhibition of mycelium growth was measured by the mycelium growth rate assay method, and the bacteria dish (5 mm in diameter) was taken from the edge of the pre-cultivated test bacteria on the PDA plate, and the mother liquor of the test ...

Embodiment 2

[0020] Weigh the compound and conventional auxiliary materials such as lignin and diatomaceous earth according to the conventional process to prepare a wettable powder with an active ingredient concentration of 2%.

Embodiment 3

[0022] Weigh the compound and conventional auxiliary materials such as calcium dodecylbenzenesulfonate, styrene-ethylphenol polyoxyethylene ether, solvent oil, etc., and make an emulsifiable concentrate with an active ingredient concentration of 2% according to a conventional process.

Abstract

The invention discloses application of a natural ceratopyran coumarin compound, namely 3',4'-diacetylkhellactone, as agricultural fungicide. The compound serving as the fungicide is used for preventing and controlling agricultural fungal diseases and can effectively prevent and control crop diseases such as rape sclerotinia rot, rice sheath blight disease and gray mold of strawberry. The agricultural fungicide prepared by taking the compound3',4'-diacetylkhellactone as an active component has the characteristics of good control and prevention effect, broad-spectrum property, low toxicity, no residues, no pollution and no public hazard, and is particularly favorable for environmental protection.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to the use of an angle-type pyranocoumarin compound 3', 4'-diacetylkhelactone as an active ingredient to prepare an agricultural fungicide. Background technique [0002] Crop diseases are not as easy to be detected in time as pests and weeds, so they often cause neglect and difficulty in prevention and control, so their harm is even more serious. According to reports, there are as many as 10,000 plant diseases caused by pathogenic fungi in the world, and the losses caused account for 10% to 30% of the total annual crop losses. If plant diseases caused by viruses, bacteria and nematodes are included, the losses will be even more considerable. [0003] In order to meet people's increasing demand for food and other living materials, chemicals have to be used to protect crops from harmful organisms, among which fungicides play an important role. Natural products with a...
