Abstract

The invention discloses a bactericide composite, belonging to the technical field of compounded pesticide. The trifloxystrobin and chlorothalonil compounded pesticide is characterized in that the mixture ratio of the trifloxystrobin and the chlorothalonil is 1:70-20:1. The trifloxystrobin and chlorothalonil compounded pesticide can be used for multiple crops in order to control multiple plant diseases, and has good effects on the Peronospora and the immunoenzyme germina; furthermore, as the ingredients have different mechanism of action to have mutual synergy, the drug fastness of germina is reduced, and the sterilizing effect of the composite is obviously higher than the sterilizing effect when each of the ingredients is singly used, thus having the advantages of synergy and expanding sterilization spectrum, etc.

Description

A kind of microbicide compositions
Technical field
The present invention relates to a kind of microbicide compositions that contains oxime bacterium ester and tpn.Above-mentioned two series bactericidal agents are mixed, can produce unexpected synergistic effect.The invention further relates to the various formulations, particularly bactericidal suspending agent of above-mentioned composition.
Background technology
Oxime bacterium ester biological is a class systemic fungicide, and Peronospora, Phytophthora fungi are had good killing effect.But when alone the sterilization duration short, protection effect is not ideal, if with some in absorption or protective fungicide make composition, their bactericidal effect can have the increase of surprising degree.
The composition of absorption in some, contact and soil fungicides and oxime bacterium ester biological composition has been introduced by Switzerland Novartis Co.,Ltd in patent EP472300, in these, absorptions, contact and soil fungicides comprise Jiameiling, white urea cyanogen, aliette, mancozeb, the spirit of gram bacterium etc.Above-mentioned composition is made the regular dosage forms such as wetting powder, suspending agent, emulsion, and these formulations are generally that after the prolonged application dilution, foliar spray uses, and effect is bad, resistance produces fast.
Tpn is the protectiveness wide-spectrum bactericide, at plant surface, good adhesivity is arranged, and longevity of residure 7-10 days, can prevent and treat downy mildew on crop, gray mold, powdery mildew, anthracnose, early blight of tomato etc.Various mix preparations to tpn in prior art have report, as disclosing the tpn biocide preparation in CN1212834.
When above-mentioned oxime bacterium ester and chlorothalonil used separately, the bactericidal action spectrum was narrow, and dosage is large, and the longevity of residure is short, easily develops immunity to drugs.In order to overcome above-mentioned weak point, the inventor is surprised to find that oxime bacterium ester is mixed use with tpn to have unexpected synergistic effect through the further investigation screening.The inventor has also developed the various formulations of above-mentioned composition, particularly its bactericide suspending agent, thereby has completed the present invention.
Summary of the invention
The present invention relates to a kind of microbicide compositions that contains oxime bacterium ester and tpn.The structure formula as described below (I) of oxime bacterium ester in the present invention:
Figure S2008101329862D00021
At above-mentioned oxime bacterium ester bactericide chemical name: (E)-methoxy imino-(E)-a-[1--(a, a, a-trifluoromethyl-m-phenyl) ethyleneimine oxygen] and o-tolyl } methyl acetate.The chemical name of tpn is tetrachloro-1,3-benzene diformazan eyeball.
Also have the oxime bacterium ester of formula (I) of synergy effective dose and the tpn of formula (II) in the application's composition.Preferably, the mixing ratio of the formula that contains in the present composition (I) oxime bacterium ester and tpn, with the weight of active constituent count 1: 70~20: 1, preferred 1: 50~10: 1, more preferably 1: 20~5: 1.
Above-mentioned composition of the present invention can be mixed with various dosage forms, the formulations such as wetting powder, granule, suspended emulsion.Can also comprise various surfactants, auxiliary agent or the carrier of preparing pesticidal preparations in above-mentioned preparation.Active ingredient accounts for 0.5%~95% weight of composition total weight in preparation, preferred 1%~70% weight.
The mechanism of action of the various compositions of composition of the present invention is different, synergy mutually between them, and the pesticide resistance of germ reduces, so the bactericidal effect the when bactericidal effect of composition is alone apparently higher than each component namely have synergistic effect, and fungicidal spectrum is wider.
Composition of the present invention can be used for various crop prevent and treat multiple diseases, mainly to Peronospora, the epidemic disease enzyme belongs to germ that good inhibition is arranged.Can be used for cucumber, grape, tomato, potato, longan, pimento etc., double controlling by other germ disease.And has a good control efficiency.
Embodiment
Embodiment 1:
The auxiliary agent of suspending agent has wetting agent 1~11%, antifreeze 1~3%, thickener 0.1~3%, defoamer 0.1~3% and media assemblage, and per distribution ratio is for accounting for composition raw bactericidal material weight percent proportioning.Wetting dispersing agent in suspending agent adopts a kind of or mixture in polyoxyethylene triphenyl phosphorus hydrochlorate, alkylnaphthalene sulfonate, polyaryl phenol polyoxy ethyl ether phosphate alkylammonium salt; Antifreeze adopts a kind of in propane diols, glycerine, ethylene glycol; Thickener adopts xanthans or aluminium-magnesium silicate; Defoamer adopts silicone defoaming agent; Filler adopts water; With oxime bacterium ester 10g, tpn 40g, polyaryl phenol polyoxy ethyl ether phosphate alkylammonium salt 6g, ethylene glycol 8g, xanthans 0.4g, organosilicon 0.1g, water is mended to 100g.Through processing to get 50% oxime bacterium ester tpn suspending agent.
Embodiment 2:
Oxime bacterium ester 5g, tpn 45g, polyoxyethylene nonylphenol ether 4g, dispersing agent NNO 3g, polyvinyl alcohol 1.2g, sodium bicarbonate 1g, bentonite 30g, kaolin are added to 100g, make 50% oxime bacterium ester tpn dispersibility granula through pulverizing granulation.
Embodiment 3:
With oxime bacterium ester 20g, tpn 50g, detergent LS (to methoxyl group fatty acid Sodium p-aminobenzene sulfonat) 2g, dispersing agent NNO (sodium methylene bis-naphthalene sulfonate) 4g, white carbon 5g, kaolin adds to 100g, mixture carries out air-flow crushing, makes 70% oxime bacterium ester tpn wetting powder.
Test with the pesticidal preparations control cucumber downy mildew that above-described embodiment makes.
1, test is processed: this test medicine consumption is established respectively three concentration for the treatment of according to the difference of each composition, but the contrast medicament is respectively commercially available agricultural chemicals 70% tpn wet-milling (WP) and 12.5% oxime bacterium ester suspending agent and the test of blank clear water.
