Abstract
The invention relates to an insecticidal composition contained with fipronil and indoxacarb. The insecticidal composition takes the fipronil and the indoxacarb as the active components, wherein, the mass ratio between the fipronil and the indoxacarb is between 10:1 and 1:10. The invention is used for controlling the resistant insects in agriculture, especially for the diamondback moths, and the like.
Description
Technical field
The composition pesticide that the present invention relates to is to be active ingredient with fluorine worm nitrile and indenes worm prestige, is used to prevent and treat the insect on the agricultural, is particularly useful for preventing and treating vegetables diamond-back moth etc.
Background technology
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 can cause total crop failure when serious.Diamond-back moth easily develops immunity to drugs, and is difficult to control, and is very big to the Chinese cabbage production loss.Diamond-back moth is worldwide insect, and insecticide is easily produced resistance and is celebrated, and various conventional dose such as organic phosphates, chrysanthemum ester class have been produced very strong resistance.
At present, control vegetables diamond-back moth is adopted Avermectin more, Avermectin is the biogenic pesticide of high-efficiency broad spectrum, extensive use in insect and control of pest mite.Along with this medicine is extensive use of for years, insect, evil mite also are on the rise to its development of drug resistance.According to relevant report, in Yunnan, Wenzhou and area, Jinhua, area, Quanzhou, Fujian Province diamond-back moth be ascendant trend year by year to the resistance of Avermectin.Relevant studies show that, diamond-back moth to the resistance of Avermectin in case produce, even later on the long period stop going up and use this medicine, diamond-back moth is to also difficult recovery of susceptibility of this medicine.Diamond-back moth has produced stronger pesticide resistance to Avermectin, should not continue to use this medicine.
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.The insects such as effectively to prevent and treat the vegetables diamond-back moth that is mixed of fluorine worm nitrile and indenes worm prestige.Being mixed and using still unmanned report of fluorine worm nitrile and indenes worm prestige.
Fluorine worm nitrile (fipronil), be that a kind of Phenylpyrazole insecticides, insecticidal spectrum are wide, to insect based on stomach poison function, have concurrently and tag and certain systemic function, its mechanism of action is to hinder the chloride metabolism of insect γ-An Jidingsuan control, and a series of important pests such as Lepidoptera, fly class and coleoptera are had very high insecticidal activity.
Indenes worm prestige (indoxacarb) mainly is the sodium channel in the blocking-up insect nerve cell, causes target pest to coordinate poor, paralysis, and is final dead.Medicament enters polypide by tagging and getting food, and the behavior of insect changes rapidly, causes insect to stop rapidly getting food, thereby protects the target crop admirably.Test shows that indenes worm prestige and other insecticide do not have cross resistance.
Summary of the invention
Technical problem to be solved: the objective of the invention is to solve in the prior art develop immunity to drugs problem and actual control efficiency of insect relatively poorly, the Pesticidal combination that contains fluorine worm nitrile and indenes worm prestige of a kind of effective control vegetables diamond-back moth is provided.
Technical scheme: for achieving the above object, the invention provides a kind of Pesticidal combination that contains fluorine worm nitrile and indenes worm prestige, effective ingredient is made up of fluorine worm nitrile and indenes worm prestige, and the mass ratio of fluorine worm nitrile and indenes worm prestige is between 10: 1-1:10.
The described Pesticidal combination that contains fluorine worm nitrile and indenes worm prestige, the mass percentage content of effective ingredient fluorine worm nitrile and the two accumulation of indenes worm prestige is between 1%-50%.
The described Pesticidal combination that contains fluorine worm nitrile and indenes worm prestige is made the application forms that comprises missible oil, suspending agent, wetting powder or water dispersible granules when practical application.
Technology of the present invention source and effect:
The present invention prevents and treats the vegetables diamond-back moth and has unique mechanism of action, does not have cross resistance with other insecticide, is applicable to the control diamond-back moth, and has and tag and certain systemic function, and insect stops to get food very soon after the dispenser, and is effective to the protection of crop.
In order effectively to administer the vegetables diamond-back moth, carried out the prescription screening study with fluorine worm nitrile and indenes worm prestige active ingredient:
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, every dish Chinese cabbage seedling falls the ovum amount when reaching 500 left and right sides, takes out Chinese cabbage seedling dish, is 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 95% fluorine worm nitrile, and the former medicine of 94% indenes worm prestige is mixed with required preparation by Huizhou City Zhongxun Chemical Industry Co., Ltd research and development centre.
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%; The 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.
