Abstract
The invention discloses a kind of containing trifloxystrobin and the bactericidal composition of jamaicin, it is that trifloxystrobin and jamaicin compounding are formed by active ingredient, and the weight ratio of trifloxystrobin and jamaicin is 1:60‑60:1;The bactericidal composition of the present invention can be prepared into the regular dosage forms such as wettable powder, water dispersible granules, suspending agent, microcapsule suspending agent, granule or aqueous emulsion.The bactericidal composition can be used for the disease for preventing and treating various crop, especially rice disease.Microbicide compositions of the present invention have efficient, environmental contamination small, delay the advantages of germ resistance to the action of a drug is produced.
Description
Technical field
The invention belongs to technical field of pesticide, it is related to composition pesticide, particularly relates to a kind of containing trifloxystrobin and small
The bactericidal composition of bark of a cork tree alkali.
Background technology
In the whole growth course of crop, the threat of the evil thing such as numerous diseases, worm, grass is faced with, wherein disease, especially
It is fungal disease, because its species is various, complicated symptoms, propagates the features such as rapid, harm is serious and plyability occurs and make it
Difficulty of prevention and cure is increased, and grave danger is constituted to crop yield and quality.In agricultural production process, in order to reduce because of fungoid
The loss that disease is caused, chemical prevention is one of current more significant means, but due to for a long time, unicity, continuity,
Scientific Usage of Drugs means do not have resulted in many pathogens and produce different degrees of resistance to currently used medicament repeatability etc., and according to
Report, due to this unscientific medication means, the resistance generation time of various medicaments shortens year by year, causes cost accounting, ring
Border cost, medicament R&D costs are significantly increased.Based on this present situation, effect of drugs is improved on the basis of existing to solve above-mentioned ask
Inscribe relatively inexpensive effective means.
Trifloxystrobin class wide-spectrum bactericide be from natural products Strobilurins as bactericide lead compound successfully
The new fungicides of a class of exploitation.With efficient, wide spectrum, protection, treat, root out, permeate, the punching of systemic activity, resistance to rainwater
The characteristics such as brush, lasting period length.To Isosorbide-5-Nitrae-demethylation enzyme inhibitor, benzamides, dicarboxyl amine and benzimidazole are produced
The bacterial strain of resistance effectively, bactericide no interactions resistance is had with current.To nearly all Mycophytes (Ascomycetes, Basidiomycetes,
Oomycete and Fungi Imperfecti) disease such as powdery mildew, rust, Ying's rot, net blotch, downy mildew, rice blast etc. has good work
Property.In addition to having special efficacy to powdery mildew, leaf spot, there is good activity to rust, downy mildew, damping-off, apple apple scab.To making
Thing safety, because its in soil, water it is capable of being fast degraded, it is therefore environmentally safe.Due to trifloxystrobin have wide spectrum, infiltration, quick point
The performances such as cloth, it has upward absorbability soon, in addition for crop absorption, therefore resistance of rainwater washing against performance is good, the lasting period is long, therefore quilt
It is considered second generation methoxy acrylic bactericide.Trifloxystrobin is mainly used in cauline leaf process, and protection activity is excellent, and has
Certain therapeutic activity, and activity is not affected by environment, is spore germination and early stage stage using optimal period, but to black star
Each sick period is active.
Jamaicin is also known as berberine.A kind of common morphinane alkaloid, molecular formula C20H18NO4, its structure is as follows:
Jamaicin is present in many plants of the section ten of Berberidaceae etc. four category.M.-E. Xia Waliai and G. in 1826
Pei Ertan is obtained first from Xanthoxylonclava barks.Jamaicin is a kind of quartermary ammonium alkaloids.It can be separated out from ether
Yellow needle-like crystals;145 DEG C of fusing point;Water is dissolved in, benzene, ether and chloroform is insoluble in.It is mainly used in treatment gastroenteritis, bacillary dysentery
The enteric infections such as disease, eye conjunctivitis, otitis media suppurative etc. are effectively.Recently it has also been found that this product has blocking alpha-receptor, the anti-rhythm of the heart loses
Often effect.
Jamaicin has to hemolytic streptococcus, staphylococcus aureus, gonococcus and Freund, Shigella shigae etc.
Antibacterial action, and have enhancing white blood cell phagocytosis, also there is different degrees of inhibitory action to tubercle bacillus, plague bacillus, to big
The amoeba bacterium of mouse also has suppression effectiveness.Jamaicin has anti-curare to act in animals, and with peripheral decompression and solution
Heat effect.The hydrochloride (being commonly called as Halomine) of jamaicin is widely used in treatment gastroenteritis, bacillary dysentery etc., to lung knot
Core, scarlet fever, acute tonsillitis and respiratory tract infection also have certain curative effect.The traditional Chinese medical science is often big with the coptis, golden cypress, barberry and ten
Contribution etc. makees clearing heat and detoxicating medicine, and wherein principle active component is jamaicin.
Agricultural chemicals is made in the combination of active principles of different agricultural chemicals, is current exploitation and develops novel pesticide and prevent and treat agriculturally
A kind of effective and quick way of resistance germ.After the pestsides synthesis of different cultivars, three kinds of type of action are typically exhibited:Phase
Plus effect, synergistic effect and antagonism.Compound synergic is formulated well, can significantly improve actual prevention effect, reduces agriculture
The usage amount of medicine, is the important means of integrated control disease so as to greatly delay the drug-fast generation speed of germ.
Synergistic bactericidal composition can not only greatly improve preventive effect, reduce dosage, cost is reduced, while can also avoid
Phytopathogen produces the generation speed of resistance and delaying drug resistance, be solve current agricultural chemicals it is alone when resistance and Cost Problems one
Plant effective means.Therefore, exploitation has the bactericidal composition of synergistic effect significant to fungal disease.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
When the prior art for being considered as recognizing or implying the information structure in any form well known to persons skilled in the art.
The content of the invention
In order to which the dosing for overcoming above-mentioned single bactericide to exist is big, environmental pollution is serious, germ resistance produces speed
The shortcomings of spending fast, the present invention provides a kind of efficient, safety containing trifloxystrobin bactericidal composition.Under optimal proportion, composition
With notable synergistic effect, the usage amount of medicament is reduced in the case where ensureing optimal preventive effect, cost is reduced, the harm to environment is reduced,
And be beneficial to delay the drug-fast generation of germ.
The technical scheme that the present invention is provided is:
