Abstract
The invention relates to an insecticidal component with the active compounds of Emamectin Benzoate and Chlorfenapyr with the mass proportions of between 1:20 and 20:1, which is composed of Emamectin Benzoate and Chlorfenapyr. The insecticidal component is used for controlling resistant pests agriculturally, in particular for controlling resistant diamond back moth, and has the characteristics of high control efficiency, long effect lasting and safety.
Description
Technical field
The present invention relates to a kind of composition pesticide, is the Pesticidal combination of active ingredient with emamectin-benzoate and capillary specifically.
Background technology
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 super-high-efficient, 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.
Capillary (chlorfenapyr) is the new pyrrole compounds, acts on the mitochondria of insect bodies inner cell, works by the mixed-functional oxidase in the insect bodies, mainly suppresses the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP).Have stomach toxicity and action of contace poison.Permeability is strong on the blade face, and certain systemic function is arranged, and has that insecticidal spectrum is wide, preventive effect is high, holds long, the safe characteristics of imitating.Can control resistant insect.
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 emamectin-benzoate and capillary.
Summary of the invention
Technical problem to be solved: the purpose of this invention is to provide the Pesticidal combination that a kind of emamectin-benzoate and capillary are mixed.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 emamectin-benzoate and capillary, to form by emamectin-benzoate and capillary, the mass ratio of emamectin-benzoate and capillary is 1: 20-20: between 1.
The Pesticidal combination of emamectin-benzoate and capillary is made different application forms when practical application, comprise missible oil, microemulsion, suspending agent, wetting powder, water dispersible granules.
Preferably, the mass percentage content of its active ingredient of the Pesticidal combination of emamectin-benzoate and capillary in preparation is between 1%-40%.
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 emamectin-benzoate and capillaries, 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% emamectin-benzoate, and the former medicine of 94.5% capillary 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
90And mixture co-toxicity coefficient, relatively synergy situation.
Table 1 emamectin-benzoate and capillary and different proportioning are to diamond-back moth toxicity test result
