Abstract
The invention discloses applications of natural compound Murrayone as an agricultural bactericide. Natural compound Murrayone is taken as an agricultural bactericide used for preventing and treating agricultural fungal diseases, is capable of preventing and treating Sclerotinia sclerotiorum, Thanatephorus cucumeris, Botrytis cinerea, Fusarium graminearum, Colletotrichum gloesporioides, and Alternaria solani effectively, and possesses excellent treatment effects on fungal diseases such as Sclerotinia sclerotiorum, Thanatephorus cucumeris, and Colletotrichum gloesporioides. Agricultural bactericides prepared by taking natural compound Murrayone as an active ingredient possesses excellent curative effects, broad spectrum activity, and low toxicity, and are especially beneficial for environmental protection; no residue is left; and no pollution is caused.
Description
Technical field
The invention belongs to agricultural technology field, be specifically related to the purposes of a kind of natural simple coumarin compound murrayone Murrayone as active fraction preparation agricultural bacteriocide.
Background technology
The disease of crops is discovered by people in time due to easy unlike insect and weeds, so often cause the ignorance in control and difficulty, thus its harm is just even more serious.It is reported, whole world list is that the plant disease caused by disease fungus just reaches 10,000 kinds, and the loss caused accounts for 10% ~ 30% of crop year total losses.If the plant disease that virus, bacterium and nematode etc. cause also is calculated interior, its loss is just more considerable.
In order to meet people to grain and the growing needs of other living material, have to adopt chemicals with cover crop by the invasion and attack of pest, wherein bactericide plays an important role.There is the natural products of agricultural bactericidal activity, be generally easily absorbed by plants and conduct, little or without poisoning to phyto toxicity, therefore extremely pay attention to.
Compound Chinese murrayone, English name Murrayone, molecular formula: C
15h
14o
4, CASNo.19668-69-0, derives from rutaceae kamuning
murrayaexoticaL.molecular structure:
Compound murrayone Murrayone, is dissolved in the organic solvents such as methyl alcohol, ethanol, acetone, ethyl acetate, chloroform.Less to the research of its active function, do not have as agricultural bacteriocide at the pertinent literature agriculturally applied or report so far.
Summary of the invention
The object of the invention is to explore compound murrayone Murrayone and preparing the application of agricultural bacteriocide as active component.
The present invention is proved by large quantity research, compound murrayone Murrayone has excellent bactericidal activity as the agricultural bacteriocide that active fraction preparation obtains, can be applicable to the fungal disease on the various crops of control, as: sclerotinia rot of colza, rice sheath blight disease, grey mould fruit rot of strawberry, wheat scab, pepper anthracnose, early blight of tomato etc.Especially obvious to fungal disease sclerotinia rot of colza, rice sheath blight disease and pepper anthracnose control efficiency.
Compound murrayone Murrayone is that separation and purification obtains from natural plants, also obtains by chemical synthesis process.Compound murrayone Murrayone is mixed with any one formulation that agricultural chemicals allows as active component and insecticides adjuvant, excipients.It can also with other agriculture chemical compounding, be mixed and made into insecticides adjuvant, excipients any one formulation that agricultural chemicals allows.Described formulation can be missible oil, suspending agent, aqueous emulsion, wetting powder, microemulsion or water dispersion granule etc.Auxiliary agent used can adopt calcium dodecyl benzene sulfonate, pyrrolidones, the rare block compound of polyoxyethylene polyoxy third, polyoxyethylene nonylphenol ether etc., and excipient can be cyclohexanone, solvent naphtha, solvent naphtha, water, propane diols, deionized water etc.Composite other agricultural chemicals used can be organic bactericide class, as triazole bactericidal agent Triadimenol; Botanical fungicide, as allicin etc.
Beneficial effect of the present invention compared with the prior art: compound murrayone Murrayone is as bactericide, and antimicrobial spectrum is wide, and the lasting period is long, is agriculturally desirable bactericide.Compared with general chemical pesticide, owing to deriving from the extract of natural plants, for economic crops such as various grain, melon and fruit, vegetables, there is low toxicity, noresidue, pollution-free, non-harmful feature, more favorable environment protection.
Embodiment
Below by way of embodiment, effect of the present invention is described further:
Embodiment 1: compound murrayone Murrayone is to the control of agricultural disease
Strains tested sclerotinite (
sclerotioiaselerotiorum) obtain from the separation of sclerotinia rot of colza bacterial strain; Rhizoctonia solani Kuhn (
thanatephoruscucumeris)be separated from the sick leaf of rice sheath blight disease; Botrytis cinerea (Botrytiscinerea), obtains from grey mould fruit rot of strawberry separation also known as the pathogen of Botrytis cinerea; Fusarium graminearum (
fusarium.graminearm) obtain from the separation of wheat scab fringe; Rhizoctonia cerealis (
rhizoctoniasolani) obtain from the separation of wheat sharp eyespot leaf; Phytophthora capsici (
phytophthoracapsici) be separated from capsicum diseased plant; Capsicum thorn dish spore [
colletotrichumcapsici(syd.) Butl.] obtain from the separation of pepper anthracnose fruit; Sporulation (
alternariasolani.) obtain from the separation of early blight of tomato leaf.
Test compound murrayone Murrayone(is located away from rutaceae kamuning, is Compound Compound murrayone Murrayone through Spectral Identification, and be dissolved in methyl alcohol and make 1000 μ g/mL mother liquors, 4 DEG C save backup.PDA medium: 200g peeled potatoes is cut into block, after boiling 10min, gets juice, adds 20g agar, is heated to fusing, then adds 20g glucose, be settled to 1000mL with water.
Mycelial growth rate determination method is adopted to measure the suppression of mycelial growth, from PDA flat board, pre-incubated beating for examination bacterium edge gets bacterium dish (diameter 5mm), by reagent agent mother liquor and medium Homogeneous phase mixing, reagent agent ultimate density is made to be 30ppm, mixed liquor impouring diameter is make flat board in the sterilizing culture dish of 9cm, a bacterium dish inoculated by every ware, and mycelia faces up, and often processes repetition 3 times.25 DEG C are cultured to contrast bacterium colony when being covered with culture dish more than 2/3rds, and right-angled intersection method is measured bacterium colony and increased diameter.Growth inhibition ratio is calculated by colony diameter mean value (mm).
With Osthole Osthol for positive reference substance, can find out that from result compound murrayone Murrayone can prevent and treat sclerotinia rot of colza, rice sheath blight disease, grey mould fruit rot of strawberry, wheat scab, pepper anthracnose, early blight of tomato etc. effectively, concentration 30ppm is respectively 40.91%, 46.99%, 32.30%, 24.67%, 50.54%, 24.66% to this several disease suppression rate, and specific experiment the results are shown in Table 1; Fully demonstrate the remarkable result of agricultural chemicals of the present invention by experiment, especially obvious to fungal disease sclerotinia rot of colza, rice sheath blight disease and pepper anthracnose control efficiency.
