Description
Technical field
The present invention relates to composition pesticide, preparation and its application, the present invention is more particularly directed to a kind of containing 2-cyano-3-amino-3-phenylancryic acetate-containing
Ternary composition, seed treatment suspending agent and its application.
Background technique
In modern agricultural production, carrying out processing to seed using seed treatment is prevention and treatment subterranean pest-insect and crops soil
One of biography, method of economical and convenient of seed-borne disease.Compared to it is conventional it is spraying, dust and soil treatment, seed processing technology are
Most economical in plant pest management, most efficient method.Seed treatment can not only reduce Pesticide use amount, while can also subtract
Few crop growth period Pesticide use number.In China, pesticide reduction must be by selecting using have become pest and disease damage Sustainable Treatment.
2 months 2015 Ministry of Agriculture print and distribute " to the year two thousand twenty Pesticide use amount zero growth rate action scheme ", and the agriculture of the year two thousand twenty China is striven in proposition
Medicine realizes the ambitious goal of zero growth rate using total amount, therefore is increasingly valued by people.
It is well known that rice growing season pest and disease damage is the chief threat in rice safety production, and bakanae disease of rice, rice
Banded sclerotial blight and rice leaf roller are exactly main several in many pest and disease damages of rice.In normal year, in order to reduce rice disease
Pest injurious loss will often carry out 5-6 spraying prevention and treatment, and in outbreak year part, times for spraying is more up to 8-10 times.Traditional stem
Foliar spray mist prevention and treatment spraying times are more, and medicament utilization rate is low, easily causes the drug resistance of rice pest, while causing dirt to environment
Dye, and then cause other a series of social concerns.Therefore applications of pesticide amount how is reduced, access times is reduced, is current rice
Urgent problem to be solved in production.And the easy-to-use operation scheme of rice paddy seed processing technique then becomes necessarily choosing instantly
It selects, which can not only reduce Pesticide use amount, while also can be reduced crop growth period Pesticide use number, for rice master
The prevention and treatment of pest and disease damage is wanted to can reach the effect got twice the result with half the effort.
Therefore it develops one kind to save labor and reduce Pesticide use amount or number, and can the effective simultaneous Bakanae disease of rice of harnessing the river, water
The sheath and culm blight of rice and the rice paddy seed of rice leaf roller processing suspending agent and its application method have emphatically the production of China's rice safety
Big meaning.
2-cyano-3-amino-3-phenylancryic acetate (Phenamacril, 2- cyano -3- amino -3- ethyl phenylacrylate) is that applicant researches and develops initiative
A kind of disinfectant use in agriculture kind.Belong to 2- cyanoacrylate fungicide, to all kinds of phytopathies as caused by sickle-like bacteria
Evil has protection and therapeutic effect, there is uptake and transmission, has higher biocidal property to the growth of bakanae disease of rice germ mycelia, passes through
It can be endangered with medicine seed soaking with whole-process control bakanae disease of rice.
Thifluzamide (the bromo- 2- methyl -4'- trifluoromethoxy -4- Trifluoromethyl-1 of Thirluzamide, 2', 6'- bis-, 3-
Thiadiazoles -5- hydroxyl anilide) belong to thiazole amide fungicide, it is succinate dehydrogenase inhibitor, inhibits germ tricarboxylic acids
Succinic acid dehydrogenase in circulation causes thallus dead.It has very strong Uptake and translocation performance, can be with foliar spray, seed at
The modes such as reason, soil treatment are applied.Thifluzamide is to Rhizoctonia, Puccinia, Ustilago, Tilletia, photovoltaicing leather bacteria
The pathomycetes such as category, Pyrenophora are active, especially have to Basidiomycetes fungus-caused disease such as banded sclerotial blight, damping-off etc.
Special efficacy.
Rynaxypyr (the bromo- N- of Chlorantraniliprole, 3- [4- chloro-2-methyl -6- [(methylamino formyl
Base) benzene] -1- (3- chloropyridine -2- base) -1H- pyrazoles -5- formamide) it is to be found and developed by E.I.Du Pont Company, belong to adjacent formyl ammonia
Yl-benzamide insecticides mainly activate blue Buddhist nun's alkali receptor, discharge the calcium ion stored in smooth muscle and striated muscle cell,
Cause pest muscle adjust it is weak, paralysis and it is lethal, almost have control efficiency to all important lepidoptera pests, efficiently
Larvicidal activity and lasting effect provide outstanding crop protection effect, and application time is flexible, fool proof to crop.
In the prior art, CN 10462346A discloses a kind of efficient germicide composition containing zinc thiazole, effectively living
Property ingredient be active components A and active constituent B, the active components A be selected from zinc thiazole, active constituent B be selected from thifluzamide, rice
One of pest amide, probenazole or 2-cyano-3-amino-3-phenylancryic acetate kind.The rice evil but the component of the prior art simultaneous simultaneously can not still harness the river
Seedling diseases, rice sheath blight disease and rice leaf roller.

Two, laboratory test
Influence of 2.1 samples of the present invention to Germination Percentage of Rice
Rice paddy seed processing suspending agent research different amounts prepared by selection example 1-6, control 1-3 send out rice paddy seed
The influence of bud rate.The japonica rice variety for being selected as southern round-grained rice 9108 is subjects.Specific implementation method is that rice paddy seed is passed through two
After the seed soaking of its two night, places 12h and drain, the every 4kg seed of seed treatment suspending agent is equal according to 40g, 50g, 60g dosage respectively
Even seed dressing, each processing respectively take 100 seeds to be placed in the culture dish for being covered with blotting paper, place 35 DEG C of 1d, and temperature is 25 later
DEG C to its germination, 3 repetitions of each processing；Blank control is that the clear water processing of rice paddy seed processing suspending agent, test knot is not added
Fruit is as shown in table 1.
Influence of the sample of the present invention of table 1 to Germination Percentage of Rice
Note: data are to repeat average three times in table 1
As it can be seen from table 1 test result show the rice paddy seed processing suspending agent of different ratio in the present invention 40,
50, when the every 4kg dosage of 60g, the final germination percentage of rice is not influenced by way of being coated after seed soaking.
Indoor toxicity test of 2.2 present invention to bakanae disease of rice
Selection example 1-6, comparative example 1-3 rice seed treating agent measurement different ratio to the total poison of bakanae disease of rice
Coefficient.Separately set three 2-cyano-3-amino-3-phenylancryic acetate, thifluzamide and Rynaxypyr single dose processing.It tests medication and uses 95% 2-cyano-3-amino-3-phenylancryic acetate
Raw medicine, 97% thifluzamide raw medicine and 95% Rynaxypyr raw medicine, are dissolved raw medicine using solvent, according to embodiment 1-6
Matched proportion density, it is spare to be configured to required concentration liquid.The method of indoor biometrics: referring to People's Republic of China's agricultural industry mark
Quasi- NY/T 1156.6-2006, the 6th part of farm-chemical indoor determination test rule fungicide: mixed synergy measurement.
Data are handled with SPSS software statistics.It finds out virulence regression equation, inhibit concentration, related coefficient, co-toxicity coefficient etc. in (lethal).
Theoretical toxicity index (TTI)=Σ (percentage of the medicine effective ingredient of the toxicity index ATI of certain medicine × in mixture
Rate)
The synergy criteria for classifying: being synergistic effect when CTC is greater than 120, is antagonism when less than 80, when 80-120
For addition.
It is 0.3814 μ g/mL to concentration in the inhibition of bakanae disease that test, which determines 2-cyano-3-amino-3-phenylancryic acetate, sets 2-cyano-3-amino-3-phenylancryic acetate to water
The toxicity index of the Bakanae disease of rice is 100.Toxicity index, the co-toxicity coefficient such as the following table 2 of each processing to bakanae disease of rice.
