Description

A kind of collaboration decrement composition pesticide containing Enestroburin
Technical field：
The invention belongs to field of agricultural fungicide, a kind of collaboration decrement pesticide combination containing Enestroburin is specifically related to Thing.
Background technology：
2-cyano-3-amino-3-phenylancryic acetate, tested number：JS399-19, chemical name is：2- cyano group -3- amino -3- ethyl phenylacrylates.By Jiangsu Prov. Inst. of Agricultural Chemicals synthesizes, and is the new type bactericide with the autonomous intellectual property of China.The medicament resistance of rainwater washing against, tool There are good interior suction penetration performance and excellent protection and therapeutic action.2-cyano-3-amino-3-phenylancryic acetate is to the Fusarium graminearum of Fusarium, string Pearl sickle-like bacteria, Fusarium oxysporum etc. have very high bioactivity, it is adaptable to which wheat scab, bakanae disease of rice and watermelon are withered Effective preventing and treating of the crop diseases such as disease.
Metconazole (Metconazole), is called hydroxyl bacterium azoles, chemical name：5- (4- chlorphenyls) -2,2- dimethyl -1- (1, 2,4- triazol-1-yl methyl)-cyclopentanol, the shape of development, mycelia and spore by suppressing or disturbing thalline appresorium and haustorium Into, can also cause film seepage aggravate, so as to reduce pathogen pathogenicity.Metconazole is a kind of efficient, triazole of wide spectrum, absorbability Series bactericidal agent, with protection, treatment, eradicant action, thus is widely used in fungus-caused a variety of by sac fungus, basidiomycetes etc. The preventing and treating of disease.
Enestroburin (Enestroburin), code name SYP-Z071 is the methoxyl group propylene of Shenyang Chemical Engineering Inst's exploitation Bactericide of phosphate (phosphinium) ester, there is special efficacy to downy mildew, powdery mildew etc., and with existing bactericide no interactions resistance.
Existing patent CN101595890A discloses 2-cyano-3-amino-3-phenylancryic acetate and the composition pesticide of triazole type, discloses 2-cyano-3-amino-3-phenylancryic acetate It can be used in mixed way with the triazole bactericidal agent such as triazolone, metconazole, Difenoconazole；Patent CN103493818A discloses cyanogen The composition of alkene bacterium ester and metconazole, for preventing and treating wheat scab, powdery mildew and rust, effect significantly, can be used for delaying Resistance development of the pathogen to triazole bactericidal agent；Patent CN102017955A discloses metconazole and methoxy acrylic The composition of bactericide, for preventing and treating downy mildew, epidemic disease, powdery mildew, scab etc..Preliminary search through applicant, without three The relevant report that person is used in mixed way.
With the raising of agricultural chemicals modernization level, present agricultural chemicals is faced with the immense pressure of ecological nuclear sterile barley.Continuously Pest-resistant is caused to strengthen using of the same race or similar toxic pesticides, peasant has to take increase dosage to be prevented Control, if things go on like this, cause vicious circle.Because the investment of new varieties of pesticides development and production is increasing with risk, market is opened The cycle of hair is increasingly longer, along with harmful organism development of drug resistance is rapid so that the supply of effective agent seems all the more short. And the use of mixed pesticide is delaying the resistance of harmful organism, is improving preventive effect, reduces cost, increases the service life, reduces agricultural chemicals To being played an important role in terms of the pollution of environment.
We screen indoors with the basis of field test, by 2-cyano-3-amino-3-phenylancryic acetate, metconazole and Enestroburin or trifloxystrobin (separately while having applied for the related application of 2-cyano-3-amino-3-phenylancryic acetate, metconazole and trifloxystrobin) is compounded, finds that there is obvious increasing Effect is acted on, and after further study, completes the present invention.
The content of the invention：
The technical problem to be solved in the present invention is to provide a kind of bactericidal effect is good, drug cost is low, wide sterilization spectrum, to wheat The fungal diseases such as head blight, powdery mildew have the composition of notable synergistic effect.In order to solve the above technical problems, the present invention is carried It is as follows for technical scheme：
A kind of collaboration decrement composition pesticide containing Enestroburin, it is characterised in that 2-cyano-3-amino-3-phenylancryic acetate, metconazole and alkene oxime bacterium The weight ratio of ester is 1-64:1-64:1-64, weight ratio preferably is 1-32:1-32:1-32, is still more preferably 1-16:1- 16:1-16, the content of active ingredient is 1-85%, preferably 20-75%.
The composition of the present invention is used for wheat scab, wheat powdery mildew, wheat rust, cucurbits fusarium wilt, wheat total eclipse The preventing and treating of fungal disease in the preventing and treating spectrum of disease, wheat sharp eyespot, rice blast, bakanae disease of rice etc..
The preparation agent that the composition of the present invention be able to can be prepared according to the method well known to those skilled in the art of the present technique Type, including water dispersible granules, wettable powder, wet seed dressing, missible oil, suspending agent, oil suspending agent, suspension emulsion, suspension seed-coating agent, water Emulsion, microemulsion etc., when preparing above-mentioned preparation, known auxiliary agent, such as emulsifying agent, profit can be added wherein as needed Hygroscopic water powder, suspending agent, disintegrant, binding agent, antifreezing agent, thickener, stabilizer, defoamer etc., suitable auxiliary agent in agricultural chemicals It may be incorporated for the present invention.
It is an advantage of the invention that it will be evident that being mainly manifested in：
1st, without antagonism between the present composition, each composition, synergistic effect is notable.
2nd, composition of the invention, expands fungicidal spectrum, bactericidal effect is more preferable.
3rd, composition compound synergic of the invention can reduce the usage amount of each single dose, and cost is low, easily promote.
Embodiment
With reference to embodiment to further instruction of the present invention, the percentage in embodiment is weight ratio, but this hair It is bright to be not limited thereto.
1st, toxicity is determined：
Toxicity Determination method is：It is dense according to the proportioning of setting by 2-cyano-3-amino-3-phenylancryic acetate, metconazole and Enestroburin active compound Degree, is configured to required decoction, standby.Test method is referred to《The experiment of NY/T 1156.2-2006 farm-chemical indoor determinations is accurate Then bactericide part 2：Suppress disease fungus mycelial growth experiment Plating》.
Aseptically, the culture medium melted in advance is quantitatively adding in sterile conical flask, from low concentration to high concentration Decoction is quantitatively drawn successively, is separately added into above-mentioned conical flask, is fully shaken up.Then equivalent pours into the training that 3 diameter above are 9cm Support in ware, the pastille flat board of respective concentration is made.Processing without medicament is used as blank control.It is repeated 4 times.
By cultured pathogen, aseptically, with diameter 5mm card punch, beaten from colony edge and take bacterium dish, used Bacterium dish is inoculated at pastille flat board center, 25 DEG C of temperature and cultivated 4 days by transfer needle, and crossing method determines measurement colony diameter, Effective middle dosage (EC that different disposal suppresses pathogen growth 50% is calculated according to formula below50Value), and compare antibacterial activity.
The bactericidal composition of the 2-cyano-3-amino-3-phenylancryic acetate-containing, metconazole and the Enestroburin that are provided using the co-toxicity coefficient method evaluation present invention Respectively to the synergistic effect of fusarium graminearum, powdery mildew and bakanae disease of rice, with the logarithm of drug concentration and preventive effect niqueMin Regression equation is sought, and calculates the EC of medicament pair50Value, then tries to achieve co-toxicity coefficient.Compound drug pair is evaluated with co-toxicity coefficient The synergy of wheat scab, powdery mildew and bakanae disease of rice, co-toxicity coefficient>120 are expressed as synergistic effect, and co-toxicity coefficient exists Summation action, co-toxicity coefficient are expressed as between 80~120<80 are expressed as antagonism.
