Abstract
The invention relates to an insecticidal component with the active compounds of spinosyns and emamectin benzoate with the mass proportions of between 1: 50 and 50: 1; the mass percentage content of the active compounds in the formulation is between 1% and 60%. The insecticidal component is used for controlling resistant pests agriculturally, especially used for controlling resistant diamond back moth.
Description
Technical field
The present invention relates to a kind of composition pesticide, is the Pesticidal combination of active ingredient with multiple killing teichomycin and emamectin-benzoate specifically.
Background technology
Multiple killing teichomycin (Spinosad) is a kind of macrolides Nuisanceless high-efficient biological insecticides that extract in the sugared many born of the same parents fermented liquid of thorn.Insect had tag fast and stomach poison function, blade there is stronger osmosis, can kill subepidermal insect, the longevity of residure is longer, can effectively preventing Lepidoptera, diptera and thrips insect, can prevent and treat well also that some measures the pest species of food blade greatly in coleoptera and the orthoptera.
Emamectin-benzoate (emamectin benzoate), it is a kind of new and effective semisynthetic antibiotics insecticide that begins to synthesize from fermented product Avermectin B1, it has efficiently, low toxicity, noresidue, the nuisanceless characteristics that wait biopesticide, active high to the larva of control lepidopterous insects and other many insects and mite class, the double again action of contace poison of existing stomach poison function.
Diamond-back moth belongs to Lepidoptera diamond-back moth section, in China south, the north distribution is arranged all, is the important pests of brassicaceous vegetable, has a strong impact on output and the economic benefit of brassicaceous vegetable.Especially at southern area, diamond-back moth is annual takes place, and takes place can cause total crop failure when serious.
Being mixed of different pesticide species is the common methods of the agriculture resistant insect of control.By Toxicity Determination, field trial etc., filter out rational prescription, can effectively improve actual control efficiency, delay the generation of pest resistance to insecticide, be the important means of integrated pest control.Being mixed and using still unmanned report of multiple killing teichomycin and emamectin-benzoate.
Summary of the invention
Technical problem to be solved: the purpose of this invention is to provide the Pesticidal combination that a kind of multiple killing teichomycin and emamectin-benzoate are active ingredient, be used to prevent and treat the insect on the agricultural, be particularly useful for preventing and treating the resistance diamond-back moth.
Technical scheme: a kind of Pesticidal combination that contains multiple killing teichomycin and emamectin-benzoate, be made up of multiple killing teichomycin and emamectin-benzoate, the mass ratio of multiple killing teichomycin and emamectin-benzoate is 1: 50-50: between 1.
Can be made into different application forms during practical application, comprise missible oil, microemulsion, suspending agent, wetting powder, water dispersible granules.
The mass percentage content of Pesticidal combination active ingredient in preparation of multiple killing teichomycin and emamectin-benzoate is between 1%-60%.
The present invention has following remarkable result:
The present invention has characteristics such as insecticidal spectrum is wide, preventive effect is high, the lasting period is long, safe, especially diamond-back moth is had good control efficiency.
In order effectively to administer diamond-back moth, the inventor has carried out the prescription screening study to active ingredients such as multiple killing teichomycin and emamectin-benzoates, and the result is as follows:
The diamondback moth larvae that gather in the field is put into off-the-shelf Chinese cabbage seedling, behind the larvae pupation, pupa is collected in the culture dish that is lined with the filter paper of preserving moisture, putting into the cage of laying eggs sprouts wings by it, the Chinese cabbage seedling that to put in order dish is then put into the cage of laying eggs allows diamondback moth larvae lay eggs, and every dish Chinese cabbage seedling falls the ovum amount when reaching 500 left and right sides, takes out Chinese cabbage seedling dish, be placed on climatic cabinate, temperature: 24-26 ℃; Relative moisture 70%-80%; Illumination: 14 (L): 10 (D)] in allow ovum hatching, raise to 3 instar larvaes.
Test medicine adopts the former medicine of 90% multiple killing teichomycin, and the former medicine of 90% emamectin-benzoate is mixed with required preparation by the present patent application people.
Adopt the malicious blade method of folder to measure: to beat with the card punch of diameter 1cm and get leaf butterfly, put into culture dish, preserve moisture.From low concentration, every leaf butterfly drop 1ul soup is treated after the solvent evaporates and another sheet scribbles that the leaf butterfly of gelatinized corn starch is involutory makes the malicious leaf butterfly of folder with the capillary dropper, and making finishes is put in the hole of 12 hole tissue culturing plates.Every processing 4 times repeats, and whenever repeats to be no less than 12 malicious leaf butterflies of folder, and the processing of establishing the corresponding organic solvent that does not contain medicament in contrast.Connect 1 examination worm in each hole of tissue culturing plate, place normal condition to cultivate.After meeting worm 2-4h, after worm to be tried is got and eaten the pastille leaf butterfly, in cultivating plate hole, add the cleaning feed and continue to raise, eliminate the examination worm that has not eaten a complete leaf butterfly to investigation.Each dosage is handled 80 of examination borer populations.Handle back 48h investigation examination worm death condition, write down total borer population and dead borer population.
According to survey data, calculate the corrected mortality that each is handled.And according to co-toxicity coefficient (the CTC value of grandson in abundant method calculating mixture.) if contrast lethality＜5%, do not proofread and correct; The contrast lethality is proofreaied and correct between 5%-20%; Contrast lethality＞20%, test need be reformed.Logarithm value according to drug concentration (mg/L) is independent variable x, is dependent variable y with the probit value of corrected mortality, sets up the virulence regression equation formula respectively, adopts DPS software to calculate the LC of single agent and each proportioning mixture
50Reach 95% confidence limit, LC
90Reach 95% confidence limit, mixture co-toxicity coefficient, relatively the synergy situation.
