Abstract
The invention discloses a kind of purposes of natural pyranocoumarin compound seselin as agricultural bacteriocide.The compound is used to prevent and treat agricultural fungal evil as bactericide, can effectively prevent and treat the corps diseases such as sclerotinia sclerotiorum, rice sheath blight disease, grey mould fruit rot of strawberry, wheat scab.The agricultural bacteriocide that natural pyranocoumarin compound seselin is made as active component has prevention effect good, and broad spectrum activity and low toxicity, noresidue, pollution-free, non-harmful feature are particularly conducive to environmental protection.
Description
Technical field
The invention belongs to agricultural technology field, and in particular to a kind of natural pyranocoumarin compound seselin is used as activity
Composition prepares the purposes of agricultural bacteriocide.
Background technology
The disease of crops due to easily being discovered in time unlike insect and weeds by people, so often resulting in preventing and treating
On ignorance and difficulty, thus its harm just it is even more serious.It is reported that whole world list is the plant disease as caused by disease fungus
Just up to 10,000 kinds, caused loss accounts for the 10%~30% of crop year total losses.If virus, bacterium and nematode etc. are drawn
Including the plant disease risen is also calculated, its loss is just more considerable.
In order to meet people it is growing to grain and other living materials the need for, it has to chemicals is used to protect
Crop is not attacked by harmful organism, and wherein bactericide plays an important role.Natural products with agricultural bactericidal activity, typically
Easily it is absorbed by plants and conducts, it is small to phyto toxicity or pay attention to without poisoning, therefore extremely.
Seselin, English name Seselin, Amyrolin, molecular formula：C14H12O3, molecular weight:228.24300, CAS
No：523-59-1, molecular structure：
The compound is dissolved in the organic solvents such as methanol, ethanol, acetone, ethyl acetate, chloroform.Less is studied to its active function,
So far not as agricultural bacteriocide in the pertinent literature or report agriculturally applied.
The content of the invention
The purpose of the present invention is to explore compound seselin as active component to prepare the application of agricultural bacteriocide.
The present invention proves that the agricultural bacteriocide that compound seselin is prepared as active component has by numerous studies
There is excellent bactericidal activity, can be applicable to the fungal disease prevented and treated on various crops, such as：Sclerotinia sclerotiorum, rice banded sclerotial blight
Disease, grey mould fruit rot of strawberry, wheat scab etc..
Compound seselin can be isolated and purified from natural plants and obtained, and can also be obtained by chemical synthesis process.Chemical combination
Any one formulation that thing seselin is configured to allow on agricultural chemicals as active component and insecticides adjuvant, excipients.It can be with
With other agriculture chemical compoundings, any one formulation allowed on agricultural chemicals is mixed and made into insecticides adjuvant, excipients.Described formulation can
To be missible oil, suspending agent, aqueous emulsion, wettable powder, microemulsion or water dispersion granule etc..Auxiliary agent used can use ten
Dialkyl benzene sulfonic acids calcium, pyrrolidones, polyoxyethylene polyoxy propylene block compound, NPE etc., excipient
Can be cyclohexanone, solvent naphtha, solvent naphtha, water, propane diols, deionized water etc..Compounding other agricultural chemicals used can be organic bactericide
Agent class, such as triazole bactericidal agent Triadimenol；Botanical fungicide, such as allicin.
Beneficial effects of the present invention compared with the prior art：Compound seselin is as bactericide, and antimicrobial spectrum is wide, the lasting period
It is long, it is agriculturally preferable bactericide.Learned to farm medicine phases ratio with vague generalization, due to the extract from natural plants, for each
Planting the industrial crops such as grain, melon fruits and vegetables has low toxicity, noresidue, pollution-free, non-harmful feature, the protection of more favorable environment.
Embodiment
Effect of the present invention is described further below by way of embodiment：
Embodiment 1：Preventing and treating of the compound seselin to agricultural disease
Strains tested sclerotinite (Sclerotioia selerotiorum) isolated from sclerotinia sclerotiorum bacterial strain；Found withered silk
Pyrenomycetes (Thanatephorus cucumeris)Separated from the sick leaf of rice sheath blight disease；Botrytis cinerea (Botrytis cinerea),
Also known as the pathogen of Botrytis cinerea is isolated from grey mould fruit rot of strawberry；Fusarium graminearum (Fusarium.graminearm) red from wheat
It is isolated on mildew fringe.
Test compound seselin, is dissolved in methanol and 1000 μ g/mL mother liquors is made, 4 DEG C save backup.PDA culture medium:
200g peeled potatoes are cut into block, boil after 10min, take juice, add 20g agar, are heated to fusing, add 20g glucose,
1000mL is settled to water.
The suppression of mycelial growth is determined using mycelial growth rate determination method, preculture supplies examination bacterium from PDA plate
Edge, which is beaten, takes bacterium dish (diameter 5mm), and reagent agent mother liquor is uniformly mixed with culture medium, makes the reagent agent ultimate density be
30ppm, mixed liquor is poured into a diameter of 9cm sterilizing culture dish and flat board is made, and a bacterium dish is inoculated with per ware, and mycelia is face-up, often
Processing is repeated 3 times.When 25 DEG C of cultures to control bacterium colony is covered with culture dish more than 2/3rds, crossing method measurement bacterium colony increases
Diameter.Growth inhibition ratio is calculated by colony diameter average value (mm).
Using Osthole Osthol as positive reference substance, compound seselin can be prevented and treated effectively as can be seen from the results
Sclerotinia sclerotiorum, rice sheath blight disease, grey mould fruit rot of strawberry, wheat scab etc., specific experiment the results are shown in Table 1；It is abundant by experiment
