Traditional Chinese medicine composition preventing stalk penicillium digitatum and sclerotinia sclerotiorum, preparation method and application thereof

Abstract

A traditional Chinese medicine composition preventing stalk penicillium digitatum and sclerotinia sclerotiorum comprises active component cortex fraxini and its extract and active component cortex dictamni and its extract, the mass percentage is respectively as follows: cortex fraxini and its extract 30 to 90% and cortex dictamni and its extract 10 to 70%. The preparation thereof is soaked in ethanol, extracted by ultrasonic and concentrated. The bacterial inhibition rate of the preparation can reach 90%. The preparation has exact effect, long effective term, non-toxic and non side effect andlow production cost, and overcomes the problems that the present chemical pesticide is easy to induce the drug resistance of pathogenic bacteria, the chemical agent residual exceeds the standard and does not meet the non-pollution requirement.

Description

technical field

[0001] The invention relates to the technical field of biopesticides, in particular to a traditional Chinese medicine composition for resisting Phomomyces sclerotiorum and Sclerotinia sclerotiorum, and its application in the preparation of biological preparations against Phoma sclerotiorum and Sclerotinia sclerotiorum. Background technique

[0002] Phoma fungi ( phoma ) belongs to Deuteromycetes, Shell Mycetes. It is widely distributed and can infect a variety of plants. It is the main pathogenic fungus that causes many plant spot diseases and blights. Zhang Jianbin et al. found that Phomomyces is one of the pathogenic bacteria of juniper red blight; G. Bohar et al. found that Phomomyces is the pathogen that causes ragweed leaf spot; A. Garibaldi et al. V. Gavrilovic et al. reported that Phomomyces was the cause of European sour cherry disease; S. G. Bobev et al. reported for the first time that Phoma was the pathogen of medicinal stachyus plants; C. R. Hol...

Examples

Embodiment 1

[0052] Mix the bark extract and moss bark extract at a volume ratio of 3:7, for example, take 3 mL of bark bark extract and 7 mL of bark bark extract, and dilute to 200 mL with water to obtain the quality described in the present invention Servings: Antibacterial agent of traditional Chinese medicine composition with 30% of Qin bark extract and 70% of white moss bark extract. The average inhibitory rates of the traditional Chinese medicine composition preparation to the two bacteria are respectively: Phomophora mulberry 88.81%; Sclerotinia mulberry 88.35%.

Embodiment 2

[0054] Mix the bark extract and moss bark extract at a volume ratio of 5:5, for example, take 5 mL of bark bark extract and 5 mL of bark bark extract, and dilute to 200 mL with water to obtain the quality described in the present invention Servings: Antibacterial agent of traditional Chinese medicine composition with 50% Qin bark extract and 50% white moss bark extract. The average inhibitory rates of the traditional Chinese medicine composition preparation to the two bacteria are respectively: 89.37% for Phomophora mulberry and 88.64% for Sclerotinia mulberry.

Embodiment 3

[0056] Mix the bark extract and the bark extract of Moss bark in a volume ratio of 7:3, for example, take 7 mL of bark bark extract and 3 mL of bark bark extract, and dilute to 200 mL with water to obtain the comparative extract of the present invention. Optimum parts by mass: the antibacterial agent of traditional Chinese medicine composition with 70% of bark of Qin bark extract and 30% of bark of moss bark extract. The average inhibitory rates of the traditional Chinese medicine composition preparation to the two bacteria are respectively: Phomora mulberry 90.34%; Sclerotinia mulberry 89.57%.
