Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a sterilization composition containing menthone.
Background
The occurrence of diseases causes great threat to agricultural production, and the use of chemical pesticides plays an important role in preventing, controlling crop diseases, ensuring stable yield and high yield of agricultural and forestry crops and the like. However, long-term application of chemical pesticides is easy to cause poisoning of people and livestock, high residue, environmental pollution and other consequences, and hidden danger is brought to ecological environment and human health.
The plant source bactericide is one medicine prepared with some parts of plant with bactericidal and bacteriostatic activity and extracted effective components and separated and purified monomer matter and through processing. The botanical fungicide gradually becomes a hot spot for controlling plant diseases due to the unique advantages of high efficiency, low toxicity, low residue, high selectivity, small influence on environment and the like. At present, scholars at home and abroad have conducted a great deal of research on the aspect of controlling fungal diseases by using a plant source bactericide, and find a plurality of plant resources with bactericidal action, which provides important basis for disease control research by using the plant source bactericide.
Currently, a plurality of plant source bactericides including ethylicin, kasugamycin, eugenol, carvacrol, osthole and the like exist in the market, are popularized and applied to the prevention and treatment of various crop diseases, and achieve remarkable prevention and treatment effects. For example Wang Zhifeng, eugenol has a strong antifungal effect and has a control effect of 78% on tomato late blight; peng Zhiguo and the like report that the control effect of the 1% osthole on powdery mildew of cucumber in a greenhouse reaches 79.33%; sun Xuemei the control effect of the ethylicin, kasugamycin, ningnanmycin and Zhongshengmycin on strawberry leaf spot disease can reach more than 80% through root dipping treatment; meanwhile, the latest researches of Zheng Anke and the like show that 9 plant source bactericides such as eugenol, allicin and osthole to be tested have an inhibiting effect on sunflower rust bacteria, 0.3% eugenol has the strongest toxicity, and the inhibiting effect is as high as more than 85%, and further show that the plant source bactericides have stronger potential for preventing and controlling plant diseases.
Menthone belongs to monoterpene compounds, widely exists in volatile oils of various plants such as peppermint, schizonepeta, baical skullcap root, wrinkled giant hyssop and the like, and researches show that the menthone has the effects of resisting viruses, resisting inflammation, promoting bile flow, promoting permeation and the like. At present, menthone and derivatives thereof are relatively widely applied in medicine and mainly used as local anesthetic, protective agent and the like, but are reported in the research process of plant diseases.
The prior researches of the inventor find that the menthone has better antibacterial effects on wheat stem basal rot, wheat scab, peanut root rot, peanut southern blight, corn scab and the like, and has better disease prevention and control potential. In order to further use menthone to develop plant disease prevention and control, the inventor develops compound researches on menthone, magnolol, carvacrol, oregano oil, osthole, eugenol, resveratrol, garlicin and other plant source bactericides, and partial compound combinations of the plant source bactericides show a strong synergistic effect, and the research results provide data support for effective prevention and control of wheat stem rot, wheat scab, peanut root rot, peanut southern blight and corn scab and have important significance for high quality and high yield of crops such as wheat, peanut and corn.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.
Disclosure of Invention
The invention aims to provide a menthone-containing bactericidal composition which can effectively inhibit the growth of pathogenic bacteria such as wheat stem rot, wheat scab, peanut root rot, peanut southern blight, corn scab and the like, effectively prevent and control various plant fungal diseases, and has important significance for the high quality and high yield of crops such as wheat, peanut, corn and the like.
In order to achieve the above purpose, the present invention provides the following technical solutions:
a bactericidal composition containing menthone is prepared by compounding magnolol, carvacrol or oregano oil and menthone as effective components.
Preferably, the mass ratio of magnolol to menthone is 1-9:9-1.
Preferably, the mass ratio of carvacrol to menthone is 1-9:9-1.
Preferably, the mass ratio of the oregano oil to the menthone is 1-9:9-1.
The invention also provides application of the menthone-containing bactericidal composition in preventing and controlling fungal diseases of crops.
Preferably, the crop fungal diseases include wheat stem rot, wheat scab, peanut root rot, peanut southern blight and corn scab.
Compared with the prior art, the invention has the following beneficial effects:
according to the invention, magnolol, carvacrol or origanum oil and menthone are compounded according to a certain mass, a synergistic effect is shown on pathogenic bacteria of various plant fungal diseases, the control effect on plant diseases can be improved, data support is provided for effective control of wheat stem rot, wheat scab, peanut root rot, peanut southern blight and corn scab, and the invention has important significance on high quality and high yield of crops such as wheat, peanut and corn.
Detailed Description

Cutting bacterial cake at the colony edge of the tested bacterial strain by using a puncher with the diameter of 5mm, inoculating the bacterial cake to the centers of a medicine-containing flat plate and a blank control flat plate, covering a dish cover, and placing the dish cover in a constant temperature oven at 25 ℃ for cultivation. When the diameter of the blank control colony grows to about 2/3 of the diameter of the culture dish, measuring the colony diameter by a crisscross method, and calculating the inhibition rate of different treatments on hypha growth.
4. Data analysis
Data statistics analysis is carried out by adopting DPS software to obtain a virulence regression equation and virulence EC of the medicament on target bacteria 50 Values and co-toxicity coefficients (CTCs) were calculated according to the grand cloud Pei method.
In the above formula: the toxicity index measured by the ATI-mixed agent; EC of S-standard agent 50 The unit is mg/L; EC of M-mixture 50 The unit is mg/L.
TTI＝TI A ×P A +TI B ×P B
In the above formula: theoretical toxicological index of TTI-blends; TI (TI) A -a toxicity index of the agent; p (P) A -a percentage of agent in the mix in percent (%); TI (TI) B -a toxicity index of the B agent; p (P) B The percentage of agent B in the mixture is expressed as a percentage (%).
In the above formula: CTC-co-toxicity coefficient; the ATI-mixed agent actually measures the toxicity index; TTI-blend theoretical virulence index.
