Embodiment 1

[0012] Embodiment 1: Compound Cniforin B prevents and treats agricultural diseases

[0013] The test strains Sclerotioia selerotiorum was isolated from rape sclerotiorum; Rhizoctonia solani (Thanatephorus cucumeris) was isolated from rice sheath blight diseased leaves; Fungus isolated from gray mold of strawberry; Fusarium graminearum (Fusarium. graminearm) isolated from ear of wheat scab; Rhizoctonia solani isolated from leaf of wheat sheath blight; Pepper Phytophthora capsici was isolated from pepper diseased plants; Colletotrichum capsici (syd.) Butl. was isolated from pepper anthracnose fruits; Alternariasolani. was isolated from tomato early blight leaves Separated to get.

[0014] The test compound, Cniforin B, 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 1000m...

Abstract

The present invention discloses uses of a natural angular furan coumarin compound Cniforin B as an agricultural bactericide. The compound Cniforin B is used for controlling agricultural fungal diseases as a bactericide, and can effectively control crop diseases such as rape sclerotinia, strawberry gray mold, wheat scab, pepper anthracnose and tomato early blight. The agricultural bactericide made by using the natural compound Cniforin B as the active ingredient has the characteristics of good controlling effect, broad spectrum, low toxicity, no residues, no contaminants and no public nuisance, and is particularly beneficial to environmental protection.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to the use of a natural horn-type furanocoumarin compound Cniforin B 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 agricultur...
