Description
Technical field
The present invention relates to the application of 2-cyano-3-amino-3-phenylancryic acetate in preventing and treating take-all, belong to technical field of pesticide.
Background technology
2-cyano-3-amino-3-phenylancryic acetate, chemical name: 2-cyanic acid-3-phenyl-3-aminoacrylic acid ethyl ester, belong to cyanoacrylate, be the new type bactericide of the autonomous initiative in Jiangsu Pesticide Research Institute Co., Ltd.Efficient, the little poison of 2-cyano-3-amino-3-phenylancryic acetate, low-residual, environmentally friendly; To have protection and therapeutic action by the microbial all kinds of plant diseases of reaping hook, can be applicable to prevent and treat the microbial wheat scab of reaping hook, cotton wilt, banana Panama disease, bakanae disease of rice, watermelon blight etc.The product of listing has only 25% 2-cyano-3-amino-3-phenylancryic acetate suspending agent a kind of at present, and the registration controlling object is wheat scab, bakanae disease of rice in the Ministry of Agriculture.
Take-all is the important root disease that generally takes place in a kind of world wide that is caused by the gaeumannomyce wheat variety.This disease is a kind of typical soil-borne disease, germ from wheat seedling stage to becoming the strain phase all can endanger.In a single day take-all takes place, and rate of propagation is very fast, and plot only needs 3 time-of-weeks from sporadicly occurring to death in blocks, and harm seriously.Wheat yield 20%-30% generally can be caused in the morbidity field, and heavy person can reach more than 50%, even total crop failure.Take-all is a kind of dangerous disease, and the Ministry of Agriculture classifies it as plant quarantine object.China finds take-all early than nineteen forty-three in Yunnan, nineteen fifty-two finds in succession that in Hebei province all there is the generation of this disease present domestic wheat main producing region.
In the control of take-all, take integrated control technique, chemical control is very important means of prevention wherein more, when wheat cultivation, wheat seed is carried out chemicals treatment have safety, efficient, economy, labour-saving characteristics.But the medicament that the whole nation is registered in the take-all control has only 125 grams per liter silicon metsulfovax suspending agents a kind of, is U.S. Meng Shan product all.The silicon metsulfovax used 4 years in China, existed resistance risk, and cost is expensive, was badly in need of a kind of substitute products of invention.
2-cyano-3-amino-3-phenylancryic acetate is used to prevent and treat take-all and does not appear in the newspapers, and the inventor finds that through a large amount of lab screenings and field control effectiveness test 2-cyano-3-amino-3-phenylancryic acetate has good control efficiency to take-all., the 2-cyano-3-amino-3-phenylancryic acetate preparation formulation do not see public reported but but being suspension seed-coating agent, seed treatment dispersion powder, seed treatment dispersible granule formulation yet.Because 2-cyano-3-amino-3-phenylancryic acetate has unique mechanism of action to pathogen, drug cost is low, and the control of using it for take-all is filled up the domestic take-all medicament blank of preventing and treating to alleviating the pathogen resistance, guarantees that Wheat Production safety is significant.
Summary of the invention
The object of the present invention is to provide the new purposes of 2-cyano-3-amino-3-phenylancryic acetate in preventing and treating take-all.

Biological Examples 2
Prevent and treat the take-all field trial
The inventor carried out FORMULATION EXAMPLE 3 (30% 2-cyano-3-amino-3-phenylancryic acetate suspension seed-coating agent) in 2011 in the Xinyue City, Hebei province and prevented and treated the take-all field trial, verified that this medicament is to the control efficiency of take-all, effective dose and to the safety of wheat.Trial crops is a wheat, and kind is that stone is new 828, and controlling object is take-all (Gaeumannomyces grami nis).Test is located at Kimura township, Xinyue City Zhong Tong village poplar and increases army's farmland covered by contract, and the plot is sandy loam ground, pH value 7.8, irrigated land.Sowing on October 13rd, 2010, the amount of broadcasting 16.5 kilograms/667 ㎡.。
Test medicine and dosage are: 30% 2-cyano-3-amino-3-phenylancryic acetate suspension seed-coating agent 50g/15kg seed, 75g/15kg seed, 100g/15kg seed, 12.5% silicon metsulfovax suspending agent 20/15kg seed, 30 g/15kg seeds.Other establishes clear water contrast, and every processing repeats for 4 times, every sub-district area 30 ㎡, and totally 24 sub-districts, district's group is arranged at random.
Dressing and seed dressing method: each handles medicine, kind amount by 4 repetitions (120 ㎡); Earlier with the medicament thin up that weighs up; Amount of water is pressed the 1500mL/100kg seed and is calculated; Then soup is slowly poured on the seed of getting ready; The limit bevelling stirs and makes soup be evenly distributed to every the surface of the seed; Vexed kind 12 hours is dried fully in the cool then and is broadcast.The quantitative hand slide of artificial trench digging method is adopted in sowing.
Investigation and statistical method:
Investigate altogether 2 times, respectively at the wheat during jointing stage investigation root system incidence of disease and harvesting wheat investigation in preceding 10 days dead ears rate.
The root system investigation: every sub-district is 5 samplings at random, get 20 strain root appearance at every, will put in order strain with spade and carefully dig out, and in clear water, rinse well, and investigation root system incidence is represented with the percentage level that each plant root is infected under white background.
0 grade: anosis;
1 grade: the root system onset area accounts for 1%～5%;
3 grades: the root system onset area accounts for 6%～20%;
5 grades: the root system onset area accounts for 21%～40%;
7 grades: the root system onset area accounts for 41%～60%;
9 grades: the root system onset area accounts for more than 61%;
Dead ears rate investigation: get the 1.5m duplicate rows at every and investigate total spike number and dead ears rate.
3. computational methods
Disease index=[∑ (diseased plant numbers at different levels * relative level numerical value)/(investigating total strain number * 9)] * 100
Control efficiency % (root system)=[(contrast disease index-processing disease index)/contrast disease index] * 100
Dead ears rate (%)=(withered dead ears number/investigate total spike number) * 100
Control efficiency % (fringe portion)=[(contrast dead ears rate-processing dead ears rate)/contrast dead ears rate] * 100
The single receipts in each sub-district of maturing stage, singles survey thousand kernel weight and output.
Security survey: investigation in 15 days has or not influence and has or not symptom of chemical damage after the wheat sowing to emerging.
Field test results shows: 30% 2-cyano-3-amino-3-phenylancryic acetate suspension seed-coating agent is pressed 50g/15kg, 75g/15kg, the seed dressing of 100g/15kg seed consumption; Take-all is respectively 85.64%, 91.25%, 94.15% in the shooting stage to the preventive effect of root system; Be respectively 82.20%, 86.02%, 90.17% in preceding 10 days preventive effects of results, the wheat increase yield rate is respectively 75.2%, 78.7%, 83.3% fringe portion.30% 2-cyano-3-amino-3-phenylancryic acetate suspension seed-coating agent 50g/15kg is lower slightly than 12.5% silicon metsulfovax suspending agent 20/15kg, 30/15kg processing preventive effect; 30% 2-cyano-3-amino-3-phenylancryic acetate suspension seed-coating agent is pressed 75g/15kg, the seed dressing of 100g/15kg seed consumption, and preventive effect and rate of growth all are higher than 12.5% silicon metsulfovax suspending agent 20/15kg, 30/15kg.
30% 2-cyano-3-amino-3-phenylancryic acetate suspension seed-coating agent shows good control efficiency to take-all, increase yield significantly, and consumption is advisable with the 75g-100g/15kg seed.
Security survey, investigation in 15 days does not have influence to emergence rate after the wheat sowing, and seedling-growing time late 1 day than blank does not have influence to late growing stage.
In sum, the present invention has supplied the new purposes of 2-cyano-3-amino-3-phenylancryic acetate bactericide, take-all is had treatment add protective effect, shows very high activity, and bactericidal effect is good, and drug cost is low, and is good to crop safety, meets efficient, the safety requirements of pesticidal preparations.
