Abstract
The invention discloses a bactericidal composition containing trifloxystrobin. The bactericidal composition comprises active ingredients in percentage by weight: 1%-70% of trifloxystrobin, 1%-70% of thiram, 1%-70% of tricyclazole and the balance of auxiliary components which are allowed for use and can be accepted in pesticide. The bactericidal composition disclosed by the invention has the advantages that the trifloxystrobin and other effective components are compounded, and an effective method for preventing germs from generating resistance is provided; whether compounding among different effective components is synergistic or antagonistic is judged according to the effect of practical application; for a compounded formula with good synergism, the practical control effect can be greatly improved, and the use amount of pesticide can be reduced, so that the generating speed of the resistance of the germs is delayed and the service life of the pesticide is prolonged.
Description
Technical field
The present invention relates to a kind of bactericidal composition, especially a kind of bactericidal composition and application thereof containing oxime bacterium ester.
Background technology
Oxime bacterium ester English name: Trifloxystrobin, Chinese another name oxime grass ester; Chemical name: (2Z)-2-methoxyimino-2-[2-[[1-[3-(trifluoromethyl) phenyl] ethyleneimino] oxygen methyl] phenyl] methyl acetate; Oxime bacterium ester is methoxy acrylic wide-spectrum bactericide, characteristics such as having efficient, wide spectrum, protection, treat, root out, infiltration, systemic activity, resistance of rainwater washing against, lasting period are long.Nearly all Mycophytes disease is all had to good activity as powdery mildew, rust, Ying's rot, net blotch, downy mildew, rice blast etc.Except powdery mildew, leaf spot are had special efficacy, rust, downy mildew, damping off, apple apple scab, sclerotinia rot of colza are had to good activity.Oxime bacterium ester is mainly used in cauline leaf and processes, and prolection is excellent, and has certain therapeutic activity, and activity is not affected by environment, and application optimal period is spore germination and their early stage stage, but scab is all had to activity each period.
In the real process of agricultural production, preventing and treating the most incidental problem of disease is the pesticide resistance that germ produces.The long-term agricultural chemicals single dose of using easily lures that disease produces serious resistance into.Therefore, exploitation has important actual application value containing the synergistic composition of oxime bacterium ester.
Summary of the invention
The object of this invention is to provide a kind of bactericidal composition and application thereof containing oxime bacterium ester that improves preventive effect and be of value to the control of germ pesticide resistance.
Technical scheme of the present invention is as follows: a kind of bactericidal composition that contains oxime bacterium ester, it contains oxime bacterium ester, tmtd and tricyclazole is active component.
In bactericidal composition of the present invention, described oxime bacterium ester 1%～70%, tmtd is 1%～70%, tricyclazole 1%～70%, all the other are in agricultural chemicals, to allow to use and acceptable auxiliary element, above percentage is weight percentage.
Oxime bacterium ester is a kind of respiratory chain inhibitor, by chain, live electronics transmission between cytochrome and stop the synthetic of cell adenosine triphosphate alcohol, thereby suppress its mitochondrial respiratory and bring into play bacteriostasis, because its action site to target pathogens is single, easily develop immunity to drugs, do not use separately.
Tmtd, English common name thiram, other title thiurams, TMTD; Chemical name: tetramethyl thiuram disulfide.Tmtd is protective fungicide, to various crop downy mildew, epidemic disease, anthracnose, Cereal smut, rice blast, seedling stage yellow blight have good control.
Tricyclazole, English name: tricyclazole, other titles are than gorgeous three match azoles, gram pest spirit, Tricyclazole; Chemical name: 5-methyl 1,2,4 one triazols (3,4-b) benzothiazole.Tricyclazole has the protective fungicide of stronger interior absorption, and bactericidal action mechanism is mainly to suppress to adhere to the melanic formation of spore, thereby suppresses spore germination and adhere to spore to form, and stops germ to invade people and the generation that reduces magnaporthe grisea spore.Tricyclazole has stronger interior absorption, can by rice root cauline leaf, be absorbed rapidly, and be transported to each portion of rice strain, generally in sprinkling rice strain in latter 2 hours, absorbs dose and can reach saturated.
The present invention can be worked to a plurality of sites of germ oxime bacterium ester, tmtd and tricyclazole are composite, thereby delays the generation speed of germ resistance, can also reduce agricultural chemicals usage amount and cost simultaneously.
Bactericidal composition of the present invention can be prepared into by known method wetting powder, suspending agent, the water dispersible granules that is applicable to agricultural use.
The auxiliary agent using in composition of the present invention comprises that solvent, dispersant, emulsifier, stabilizing agent, antifreezing agent, thickener etc. and other are of value to the known substance of active ingredient stable and drug effect performance in preparation, all various compositions conventional in pesticidal preparations or that allow to use, be not particularly limited, concrete composition and consumption require to determine by simple experiment according to formula.
The above-mentioned bactericidal composition that contains oxime bacterium ester is the application in any disease in preventing and treating powdery mildew, rust, downy mildew, rice blast, brown spot, damping off, seedling stage yellow blight, all has good activity; Especially rice blast is had to extraordinary effect.
Compared with prior art, beneficial effect of the present invention is: by oxime bacterium ester and other active ingredient, being undertaken compositely, is to avoid germ to produce the effective way of resistance.Composite between different active ingredient, according to the effect of practical application, judge that composite is synergy or antagonism.The formula that compound synergic is good, can significantly improve actual control efficiency, reduces the usage amount of agricultural chemicals, thereby delays the generation speed of germ resistance, increases agricultural chemicals service life, and concrete advantage is as follows:
1, synergistic effect is remarkable.Mixed composition, due to the application point position having increased target fungi, is compared bactericidal effect with single dose and is obviously improved.
2, after drug effect improves, the usage amount of active ingredient and medication number of times reduce, and have reduced drug cost, have reduced the pollution to environment.
3, be conducive to resistance management.Tmtd in active ingredient, tricyclazole, owing to having been used for many years, in many local resistances that produce.Due to the difference of the mechanism of action of three kinds of active ingredients in composition, alleviated the single selection pressure to germ, therefore can avoid or delay the drug-fast generation of germ.
4, expand fungicidal spectrum.Because the fungicidal spectrum of three kinds of active ingredients is variant, so composition can play the double effect of controlling of a medicine while sending out multiple diseases is mixed.
