Abstract
The invention discloses a use of Columbianetin as an agricultural pesticide. The Columbianetin which serves as the agricultural pesticide has an obvious effect in preventin and control of both Lepidoptera and homopteran insects. Furthermore, the Columbianetin serving as the agricultural pesticide has the characteristics of low toxicity, no residue, no pollution and no public nuisance, and is more beneficial to environment protection.
Description
Technical field
The invention belongs to agricultural technology field, be specifically related to the purposes of Columbianedin as active fraction preparation 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.At present still taking chemical pesticide control 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.
Columbianedin, English name Columbianetin, molecular formula C
14h
14o
4, molecular weight 246.26, chemical name: 2H-Furo[2,3-h] and-1-benzopyran-2-one, 8,9-dihydro-8-(1-hydroxy-1-methylethyl)-, (8S)-; Its molecular structure is:
Columbianedin, 162～163 DEG C of fusing points, are dissolved in the organic solvents such as methyl alcohol, ethanol, chloroform.Research finds that Columbianedin is to effects such as platelet aggregation-against, antimycotic and cytotoxins.But do not have so far Columbianedin to be applied in agricultural production as insecticide.
Summary of the invention
The object of the invention is to explore Columbianedin as active component in the application of preparing aspect agricultural fungicides.
The present invention is by studies have shown that in a large number, and the agricultural fungicides that Columbianedin obtains as active fraction preparation has good insecticidal 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; Diamond-back moth section insect is preferably diamond-back moth.Described Homoptera insect is Aphidiadae insect, is preferably black peach aphid.
Columbianedin is that separation and purification obtains or commercially available obtaining from natural plants.Columbianedin is mixed with as active component and insecticides adjuvant, excipients any one formulation allowing on agricultural chemicals.Columbianedin 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: Columbianedin is as insecticide; insect is had tag, stomach poison function; derive from the extract of natural plants; there is low toxicity, noresidue, pollution-free, non-harmful feature for economic crops such as various grain, melon and fruit, vegetables, more favorable environment protection.
Embodiment
By embodiment, effect of the present invention is described further below:
Embodiment 1 Columbianedin as active component to agricultural insect management
Be that field population 3～6 instar larvaes that gather are raised and laid eggs to pupating at indoor artificial feed for examination worm source, select indoor F1 and F2 for basically identical 1 instar larvae of size for toxicity test.Accurately take Columbianedin (purchased from Nat'l Pharmaceutical & Biological Products Control Institute), be dissolved in acetone, making concentration is that 1.000mg/ml is as for subsequent use for reagent liquid.Fresh clean cabbage leaves (wherein mythimna separata wheat leaf blade) is made to the leaf dish that diameter is 1.5cm with defoliator, 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) DEG C, 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.48h checks lethality, calculates the dead borer population of each processing, the borer population of living, and calculates larval mortality.
Result shows: in 48h, effective to prodenia litura, beet armyworm, diamond-back moth, mythimna separata, black peach aphid for reagent liquid, concrete lethality, in table 1, shows by test, and Columbianedin, as agricultural insecticide, has certain insecticidal action.
