Problems solved by technology

[0007] Throughout the above patents, most of them are mixed with matrine or osthole and plant extracts or pesticides. Only Wang Yingzi’s patent has two substances of osthole and matrine, but the main purpose is to prevent grape greens. Mirid bugs, and the patents and products on the compound application of matrine and osthole to plant pathogenic bacteria have not been publicly reported so far

Embodiment 1

[0070] Example 1: Preparation of 3% matrine·osthole environment-friendly cream

[0071] At room temperature, take 3 parts of matrine·osthole (the compounding ratio of matrine and osthole is 1:2), add 6 parts of organic silicon, 4 parts of dodecyl Sodium benzenesulfonate and 1 part of octylphenol polyoxyethylene ether and 1 part of styrylphenol polyoxyethylene polyoxypropylene ether are supplemented with ethanol + ethyl acetate + dimethylformamide (6: 3.5: 0.5) to 100 parts, stirring at a stirring speed of 100 to 200 rpm for 10 to 30 minutes, can prepare 3% matrine·osthole environment-friendly emulsifiable concentrate.

Embodiment 2

[0072] Example 2: Preparation of 2% matrine·osthole environment-friendly cream

[0073] At room temperature, take 2 parts of matrine·osthole (the compounding ratio of matrine and osthole is 1:2), add 3 parts of organic silicon, 2 parts of dodecyl Sodium benzene sulfonate and 1 part of octylphenol polyoxyethylene ether and 1 part of styrene ethylphenol polyoxyethylene polyoxypropylene ether are supplemented with ethanol + ethyl acetate + dimethylformamide (7: 2.8: 0.2) to 100 parts, stirring at a stirring speed of 100 to 200 rpm for 10 to 30 minutes, can prepare 2% matrine·osthole environment-friendly emulsifiable concentrate.

Embodiment 3

[0074] Example 3: Preparation of 1.3% matrine·osthole environment-friendly cream

[0075] At room temperature, take 1.3 parts of matrine·osthole (the compounding ratio of matrine and osthole is 2:1), add 2 parts of organic silicon, 1 part of dodecyl Sodium benzenesulfonate and 1 part of octylphenol polyoxyethylene ether and 1 part of styrylphenol polyoxyethylene polyoxypropylene ether are supplemented with ethanol + ethyl acetate + dimethylformamide (6: 3.5: 0.5) to 100 parts, stirring at a stirring speed of 100 to 200 rpm for 10 to 30 minutes, can prepare 1.3% matrine·osthole environment-friendly emulsifiable concentrate.

Abstract

The invention discloses a compounded botanical synergistic fungicide containing sophocarpidine and osthol. The obtained compounded botanical synergistic fungicide takes sophocarpidine and osthol as main components, and is added with accessory ingredients in a synergistic manner; the morphology of the compounded botanical synergistic fungicide is environment-friendly missible oil, microemulsion, aqueous solution or soluble liquid; and in addition, the compounded botanical synergistic fungicide contains sophocarpidine accounting for 0.1 to 20 percent and osthol accounting for 0.1 to 20 percent, and the rest is the accessory ingredients. The compounded botanical synergistic fungicide is mainly used for controlling downy mildew, gray mold, anthracnose, powdery mildew, cladosporium cucumerinum, soft rot and basal stem rot. The compounded botanical synergistic fungicide does not contain any chemical pesticide component, is easy to degrade in environment, has no consideration of environment pollution and residual hazard, is safe to human, livestock and environment; germs are not easy to be drug-resistant to the compounded botanical synergistic fungicide; the compounded botanical synergistic fungicide is of great value to be applied and popularized on main agricultural and sideline products that earn foreign exchange through exports, such as melons, fruits, vegetables, tea leaves and medicinal materials; and in addition, the compounded botanical synergistic fungicide is an ideal novel pollution-free bactericide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a synergistic fungicide with matrine and osthole as active components and a preparation method thereof, which is mainly used in the prevention and treatment of melons, fruits, vegetables and tea trees Downy mildew, gray mold, anthracnose, powdery mildew, scab, soft rot, stem rot and other agricultural diseases. Background technique [0002] Downy mildew, gray mold, anthracnose, powdery mildew, scab, soft rot, stem rot, etc. are the main diseases on melons, fruits and vegetables, with a wide range of damage and great difficulty in prevention and control. At present, the medicaments used to prevent and control these diseases are mainly chemical fungicides. However, the long-term use of a large number of chemical drugs has led to the emergence of problems such as drug resistance, environmental pollution, and harm to human health; The use of many chemical pesticides ha...
