Abstract
The invention provides a flavone compound for preventing and controlling plant diseases. The structure of the flavone compound is shown in a general formula I, wherein in the general formula I, R1 is H or -CH2-CH=C(CH3)2, and R2 is H or -CH2-CH=C(CH3)2. The compound provided by the invention can be used for processing a pesticide preparation for preventing and controlling oomycetes diseases.
Description
Technical field:
The present invention relates to technical field of pesticide, be specifically related to the purposes that one type of flavonoid compound with bacteriostatic activity is used for controlling plant diseases.
Background technology:
The oomycetes disease is one of cucumber, tomato and the most important disease of potatoes and other crops, generally causes underproduction 20%-30%, and the serious underproduction can reach more than 50%, even total crop failure.The current major technique means that are used to prevent and treat oomycetes disease (like cucumber downy mildew, early blight of tomato, the late blight of potato etc.) are still chemical prevention, and ICIA 5504, SN 39744, metaxanin, zinc manganese ethylenebisdithiocarbamate etc. are such sick main sterilant kinds of control.Because the oomycetes disease is a superinfection venereal disease evil, need repeatedly repeat dispenser, it is improper that pesticide application technology has slightly, promptly can cause the pesticide residue in the cutting to exceed standard, thereby threaten food safety and human health.
Summary of the invention:
Above-mentioned defective to prior art exists the object of the present invention is to provide one type of flavonoid compound with agricultural bacteriostatic activity, and this compounds can obtain by extraction separation in Moraceae ficus species ground fruit (Ficus tikoua Bur).Adopt spectroscopic techniques such as high resolution mass spectrum and nucleus magnetic resonance, confirmed the chemical structure of compound involved in the present invention, its structural formula is as follows:

Compound involved in the present invention can adopt methanol eddy to extract, and separates the pure article that obtain through ordinary methods such as silica gel column chromatographies.
Compound involved in the present invention can be with the plant milk extract of different content, or is processed into the conventional pesticide formulation through the forms such as pure article of separation and purification, like missible oil, microemulsion, aqueous emulsion, suspension agent etc.
The pesticide preparation that compound involved in the present invention is processed into can be used for preventing and treating Plant diseasess such as cucumber downy mildew, the late blight of potato and capsicum epidemic disease.
The advantage of this invention is: compound involved in the present invention distribution abundance in the ground fruit is high, and this plant distribution extensively, and breeding rapidly; Conventional solvents such as employing methyl alcohol can extract this compound from vegetable material effectively, and methyl alcohol is abundant in China source, and output is big, and self is little to the pressure of environment; The ground fruit has been used as the feed of cattle and sheep always by place of production peasant throughout the year, to Mammals and non-target organism safety; This compound has the selectivity bacteriostatic activity, only the oomycetes disease is shown very high control effect.
Embodiment
Help to understand the present invention through following embodiment, but do not limit content of the present invention.
Embodiment one
With flavonoid compound DG01 is the preparation of effective constituent cream preparation
Taking by weighing the Compound D G01 10.0g (purity >=98.0%) that the present invention relates to respectively is dissolved in the 80.0g methyl alcohol; Add AS calcium dodecylbenzene sulphonate (DBS-Ca) 3.0g again; Non-ionics OP-10 7.0g; Be stirred to transparent homogeneous phase, promptly be able to the cream preparation that this compound is an effective constituent, wherein active constituent content is 10%.
Embodiment two
With flavonoid compound DG01 is the preparation of effective constituent microemulsion
Taking by weighing the Compound D G01 5.0g (purity >=98.0%) that the present invention relates to respectively is dissolved in the 20.0g pimelinketone; Add aniorfic surfactant calcium dodecylbenzene sulphonate (DBS-Ca) 2.5g again; The peaceful newborn 334.0g of non-ionics, newborn 600 2.5g of non-ionics farming are in 50～60 ℃ of stirred in water bath to transparent homogeneous phase; Add deionized water 66.0g again; Continue to be stirred to homogeneous phase, promptly be able to the microemulsion that this compound is an effective constituent, wherein active constituent content is 5%.
Embodiment three
Potted plant control cucumber downy mildew test
With nutrition soil cultivated cucumber (kind is the close thorn in Xintai City), every alms bowl 2 strains when seedling grows 2 true leaves, are selected the consistent confession examination of growing way in the greenhouse.Supplying the reagent agent is that content is 10% DG01 cream preparation, and the contrast medicament is 50% dimethomorph water dispersion granula.Per 10 alms bowls are 1 processing, and 4 processing are established in test altogether, are respectively to supply 500 times, 1000 times of reagent dilution agents 2000 times of contrast medicament dilutions and clear water contrast, every processing repetition 3 times.After the dispenser 24 hours, artificial inoculation cucumber downy mildew cause of disease spore, 1 all investigation prevention effects after the dispenser, the result sees table 1.
Table 1 supplies potted plant the prevent and treat test-results of examination cream preparation to cucumber downy mildew
The presentation of results of table 1 supplies 500 times of control effect to cucumber downy mildew of DG01 cream preparation dilution of reagent agent 10% to reach more than 60%.
