Abstract
The invention discloses an application of byakangelicin used as an agricultural pesticide and an insect antifeedant. The byakangelicin has an obvious effect of preventing and controlling lepidopterous insects and homoptera when being used as the pesticide and the insect antifeedant, and also has the characteristics of low toxicity without any residues or pollutions when being used as the agricultural pesticide, so that environmental protection is favored.
Description
Technical field
The invention belongs to agricultural technology field, be specifically related to byak-angelicin as the purposes of active fraction preparation agricultural insect anti-feedant and insecticide.
Background technology
Pest occur in the many regional large area of China, and frequency is in rising trend, and harm increases the weight of.Still take chemical pesticide control at present as major control measure.Due to the long-term chemical pesticide control that uses, cause insect to produce pesticide resistance in various degree to number of chemical insecticides such as organochlorine, organic phosphor, carbamate, pyrethroids, control efficiency significantly declines, make peasant have to strengthen dosage to improve preventive effect, but reduced again the safety of agricultural product.
Therefore, explore efficient, safety, environmentally friendly environment friendly agricultural seems particularly important.
Byak-angelicin, English name Byakangelicin, molecular formula C
17h
18o
7, molecular weight 334.31, chemical name: 7H-Furo[3,2-g] and [1] benzopyran-7-one, 9-(2,3-dihydroxy-3-methylbutoxy)-4-methoxy-, (R)-; Its molecular structure is:
Byak-angelicin, 124～125 ℃ of fusing points, are dissolved in the organic solvents such as methyl alcohol, ethanol, chloroform.Research finds that byak-angelicin has the antitumor effect of Denging.But do not have so far byak-angelicin to be applied in agricultural production as insecticide.
Summary of the invention
The object of the invention is to explore byak-angelicin as active component in the application of preparing aspect agricultural fungicides and antifeedant for insect.
The present invention is by studies have shown that in a large number, and the agricultural fungicides that byak-angelicin obtains as active fraction preparation has good insecticidal activity and antifeedant activity, can be used for preventing and treating various pest on crop, especially for control Lepidoptera and Homoptera insect.Lepidopterous insects can be Noctuidae, diamond-back moth section insect; Described noctuid is preferably prodenia litura, beet armyworm, mythimna separata.Described Homoptera insect is Aphidiadae insect, is preferably black peach aphid.
Byak-angelicin is that separation and purification obtains or commercially available obtaining from natural plants.Byak-angelicin is mixed with as active component and insecticides adjuvant, excipients any one formulation allowing on agricultural chemicals.Byak-angelicin can also and other agriculture chemical compounding, be mixed and made into insecticides adjuvant, excipients any one formulation allowing on agricultural chemicals.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 are organic phosphates, as: thimet (3911), demeton (1059, E1059), parathion (1605, E605), dichlorvos (DDV), Rogor, chlorophos etc.; Pyrethroid, as: cypermethrin, decamethrin, kill bacterium fat etc.; Microbial source insecticide, as bacillus thuringiensis,Bt (Bt), Avermectin, white muscardine fungi etc.
Beneficial effect of the present invention compared with the prior art: byak-angelicin is as insecticide; insect is had tag, stomach poison function; as antifeedant for insect; there is stronger antifeedant activity; and it derives 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
By embodiment, effect of the present invention is described further below:
Embodiment 1 byak-angelicin as active component to agricultural insect management
For examination worm source, for field population 3～6 instar larvaes that gather, at indoor artificial feed, raise and lay eggs to pupating, select indoor F1 and F2 for basically identical 1 instar larvae of size for toxicity test.Accurately take byak-angelicin (purchased from Nat'l Pharmaceutical & Biological Products Control Institute), be dissolved in acetone, making concentration is that 1.000mg/ml is as standby for reagent liquid.With defoliator, fresh clean cabbage leaves (wherein mythimna separata wheat leaf blade) is made to the leaf dish that diameter is 1.5cm, then it is soaked in for reagent liquid and within 10 seconds, take out afterwards, rear taking-up is dried and is placed in the culture dish that contains 1% water agar or moisturizing filter paper, access the examination worm of hungry 3h, be placed in artificial climate indoor [(25 ± 1) ℃, L/D=14/10, RH75%], the liquid of each concentration is processed 30 cephalonts.Blank group is flooded blade with acetone soln, and same leaf dipping method is processed examination worm.After 48h, observe examination insect pest situation condition, check lethality, calculate dead borer population of respectively processing, the borer population of living, calculate larval mortality.
Result shows: in 48h, effective to prodenia litura, beet armyworm, diamond-back moth, mythimna separata, black peach aphid for reagent liquid, for reagent liquid group examination worm, compare blank group, food leaf amount reduces many, polypide diminishes, and concrete lethality, in Table 1, shows by test, byak-angelicin, as agricultural insecticide, has certain desinsection and insect antifeedant active.
