Abstract
The invention discloses use of a natural compound Pd-c-V(b) as an agricultural fungicide. The compound Pd-c-V(b) serving as the fungicide is used for preventing agricultural fungi diseases, can effectively prevent crop diseases such as rape sclerotinia rot, strawberry grey mould and wheat scab, and particularly has an obvious prevention effect on the fungi diseases namely the rape sclerotinia rot and the wheat scab. The natural compound Pd-c-V(b) serving as the agricultural fungicide prepared from active ingredients has the characteristics of good prevention effect, wide adaptability, low toxicity, no residue, no pollution and no public nuisance, and particularly facilitates environmental protection.
Description
Technical field
The invention belongs to agricultural technology field, be specifically related to the purposes of a kind of natural line style dihydropyran coumarin compound Pd-c-V (b) 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.

Molecular structure:
Pd-c-Ⅴ(b)R=-O-ace,R'=-O-ang
Compound Pd-c-V (b) is colorless needle crystals.Be 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 Pd-c-V (b) and preparing the application of agricultural bacteriocide as active component.
The present invention is proved by large quantity research, compound Pd-c-V (b) 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, grey mould fruit rot of strawberry, wheat scab etc.Especially to fungal disease sclerotinia rot of colza and wheat scab control efficiency obvious.
Compound Pd-c-V (b) is that separation and purification obtains from natural plants, also obtains by chemical synthesis process.Compound Pd-c-V (b) 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 Pd-c-V (b) 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 Pd-c-V (b) is to the control of agricultural disease
Strains tested sclerotinite (
sclerotioiasclerotiorum) obtain from the separation of sclerotinia rot of colza bacterial strain; Fusarium graminearum (
