Abstract
The invention discloses a sterilization composition and application thereof in a pesticide. The sterilization composition consists of epoxiconazole and thiram, wherein the weight ratio of the epoxiconazole to the thiram is 1:20-20:1, preferably 1:10-10:1. The sterilization pesticide consisting of the sterilization composition serving as an active ingredient and acceptable auxiliary components in the pesticide is used for preventing and controlling cercospora arachidicola, powdery mildew of cereals, apple altermaria leaf spot, sigatoka and the like, and can produce a synergistic effect, reduce the consumption, reduce the cost and delay the pesticide resistance of pathogenic bacteria.
Description
Technical field
The present invention relates to a kind of bactericidal composition and the application in agricultural chemicals thereof.
Background technology
The cercospora brown spot of peanut is one of the most serious leaf diseases in peanut producing region, the world, main harm blade, harm petiole and cane when serious; Mainly betide peanut growth early stage and mid-term; Cause early leaf fall, reduce the plant photosynthetic efficiency, influence nutrient accumulation and cause the underproduction.The medicament that is used to prevent and treat at present mainly contains 12.5% fluorine ring azoles list agent, 50% tmtd list agent etc.
Fluorine ring azoles is a kind of interior absorption triazole bactericidal agent, and structure suppresses the synthetic of germ ergosterol suc as formula shown in (I), hinder the formation of germ cell wall, and its molecule has powerful compatibility to a kind of fungal enzyme (14-dencthylase).Compare with present known bactericide, can more effectively suppress the germ fungal pathogens.Fluorine ring azoles can improve all fourth matter enzymic activitys of crop, causes the contraction of fungi haustorium, suppresses germ and invades, and this is fluorine ring azoles unique characteristic in all triazole type products.Diseases such as the anthracnose on leaf spot, powdery mildew, rust and the grape on the crops such as banana, green onion garlic, celery, Kidney bean, melon, asparagus, peanut, beet, white rot there is good preventive effect.The absorption of this composition is strong, can be is rapidly absorbed and conducts to susceptible position by plant, disease is infected immediately stop, and local dispenser control thoroughly.Lasting period is splendid, and as reaching more than 40 days in the bacteriostasis on the cereal, effect is stayed in remarkable holding, and has reduced medication number of times and labour costs.Can effectively control disease, can improve the biochemical disease resistance of crop self through the activity of regulatory enzyme again, the disease resistance of crop itself is strengthened greatly.Make the leaf look greener, thereby guarantee crop photosynthesis effect maximization, improve output and improve quality.
（Ⅰ） （Ⅱ）
Tmtd is the protectiveness organosulfureous fungicide, and structure has lethal effect preferably suc as formula shown in (II) to seed transmission and the traditional disease of soil in seedling stage, and animals such as beetle and mouse, rabbit are had certain deterrent effect.Main as seed dressing, also can be used for soil treatment and spraying.
But these medicaments frequently use because of heavy dose, and the peanut pesticide resistance is grown with each passing day, to the control efficiency of brown spot variation gradually.
Summary of the invention
To above-mentioned situation, the invention provides and a kind ofly can effectively improve control efficiency, delay pesticide resistance, applied widely, bactericidal composition that reduces cost and the application in agricultural chemicals thereof.
Bactericidal composition of the present invention is made up of fluorine ring azoles and tmtd jointly, and wherein the weight ratio of fluorine ring azoles and tmtd is 1
:20 ~ 20
:1, preferred weight ratio is 1
:10 ~ 10
:1.
With above-mentioned bactericidal composition is active ingredient; With auxiliary elements such as acceptable dispersant, diffusant, antifoaming agent, wetting agent, disintegrant in the agricultural chemicals; Through comprising that mixing waits usual manner, can form the Compositional type sterilization pesticide of operational different dosage form form.Wherein, can comprise like wetting powder, suspending agent or water dispersible granules etc. as preferred formulation:
A. wetting powder (WP) is can homodisperse solid powder preparation in water.Except that can in former medicine, adding as thinners such as white carbon, precipitated calcium carbonate, potter's clay, diatomite, attapulgite or the inert substance, can use ion-type or nonionic surface active agent (wetting agent, dispersant) in addition by usual manner; Like alkylbenzenesulfonate (DBS-Na), alkylnaphthalene sulfonate (drawing back powder), alkylphenol-polyethenoxy base ether sulfate; Alkylphenol-polyethenoxy base ether formaldehyde condensation products sulphate; Aliphatic alcohol sulfate, fatty alcohol ethylene oxide adduct sulfonate, alkyl amide taurate; Aliphatic alcohol polyethenoxy base ether wetting agents such as (JFC), content is generally 0.1 ~ 30w%; Like naphthalene sulfonate; Naphthalene or alkyl naphthalene formaldehyde condensate sulfonates (NO, NN0, MF); Lignin and derivative sulfonate thereof (M-9, POLYFON etc.), polyoxyethylene poly-oxygen propylene aether block copolymer, alkylphenol-polyethenoxy base ether formaldehyde condensation products sulphate (SOPA); Dispersant such as PVA, CMC, consumption is generally 0.1 ~ 30w%; In the bleeding agents such as JFC, azone, thiophene ketone, penetrant t one or more, content is generally 0.3 ~ 30w%; And other auxiliary agent or auxiliary element such as stabilizing agent, foam inhibitor, anticaking agent.
B. water dispersible granules (WDG), being can very fast disintegration in water, disperse to form the granule of higher suspension dispersion.By active component, and comprise as auxiliary agent such as wetting agent, dispersant, interleaving agent, disintegrant, stabilizing agent, adhesive and carrier etc. are common and forming.Basic and wetting powder of its compound method and suspending agent are basic identical.
C. suspending agent (SC) is not water-soluble solid pesticide or the dispersion of immiscible liquids agricultural chemicals in water or oil.Make through the wet method ultramicro grinding by active component, auxiliary agent (wetting dispersing agent, thickener, stabilizing agent, pH regulator agent, antifoaming agent, antifreezing agent).Wetting dispersing agent can be naphthalene or alkyl naphthalene formaldehyde condensate sulfonates (NO, NN0, MF), lignin and derivative sulfonate (M-9, POLYFON etc.) thereof, alkylphenol-polyethenoxy base ether sulfonate, polyoxyethylene polyoxypropylene base ether block copolymers; In alkylphenol-polyethenoxy base phosphate, carboxymethyl cellulose (CMC), polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), the condensed phosphate etc. one or more, content 0.1 ~ 12w%; Thickener and stabilizing agent can be in xanthan gum (XG), polyvinyl alcohol (PVA), the Magnesiumaluminumsilicate etc. one or more, content 0.05 ~ 0.5w%; PH regulator agent and antifoaming agent can add according to circumstances in right amount.
Result of the test shows, after two kinds of compositions of the above-mentioned bactericidal composition of composition the present invention are mixed each other, can produce the conflict effect, and can produce Synergistic, reduces dosage, reduces cost, and delays the drug-fast generation of germ.This bactericidal composition; And be the sterilization pesticide of active component with it; Can be applicable to melon and fruit class such as powdery mildew, alternaria leaf spot of apple, sigatoka and the control of greengrocery crop pest, can also be used to prevent and treat the crop pest of cereal class, like wheat powdery mildew to the cercospora brown spot of peanut, cereal crop; The banana powdery mildew, leaf spot etc.
