Description
Technical field
The present invention relates to pesticide complex composition and its application field, specifically with 2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone to have
The binary complex of effect active component compounding, is mainly used in the preventing and treating of disease on crops.
Background technology
2-cyano-3-amino-3-phenylancryic acetate, belongs to cyanoacrylate bactericide, with the spy such as efficient, micro- poison, low-residual, environmentally friendly
Point, to having protection and therapeutic action by the microbial all kinds of plant diseases of reaping hook, can be applied to preventing and treating reaping hook microbial small
Wheat head blight, cotton wilt, bakanae disease of rice, watermelon blight etc..
Benziothiazolinone, belongs to isothiazole heterocyclic compound, is a kind of efficient, low toxicity, broad-spectrum germicide, and its mechanism of action is:
Reacted with bacterium, the anion binding of the surface of cell membrane of mould or with sulfydryl, the synthesis system of destruction protein and cell membrane,
So as to suppress bacterium, mould breeding, pathogen cell metabolism is disturbed, make its physiologic derangement, cause pathogen dead.The change
Compound has good preventing and treating to diseases such as the rot on crops, canker, anthracnose, scab, leaf spot, downy mildew
Effect, and it is fool proof to crops.
The long-time of agricultural chemicals single variety is continuously used, and easily produces resistance risk and consumption to increase risk, and then increase
Cost and carrying capacity of environment, and the compounded combination with notable synergistic function is gone out by the compound screening of different pesticide species
Thing, can not only reduce Pesticide use amount, reduce use cost, reduce resistance risk, moreover it is possible to reduce potential environmental risk, increase
The Pesticide use life-span.
The present inventor during research 2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone compounded formula, surprisingly 2-cyano-3-amino-3-phenylancryic acetate
Compounded with benziothiazolinone, there is significant Synergistic to make the head blight on wheat in the range of certain compound proportion
With after further study, completing the present invention.
The content of the invention
It is an object of the invention to provide a kind of component rationally, obvious synergy, bactericidal effect is outstanding, the lasting period
Long, drug cost is low, and pathogen can be delayed to develop immunity to drugs, and to the pesticide sterilizing composite of Crop securify.
Another object of the present invention is to provide a kind of bactericidal composition preparation formulation containing 2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone.
It is still another object of the present invention to provide purposes of the above-mentioned bactericidal composition in head blight on preventing and treating wheat.
Technical scheme:A kind of bactericidal composition containing 2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone, active ingredient is by cyanogen alkene
Bacterium ester and benziothiazolinone are constituted, and 2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone weight ratio in the composition are 100:1~1:1,2-cyano-3-amino-3-phenylancryic acetate and thiophene
Percentage by weight is 0.1%~85% to the weight summation of mould ketone in the composition, and remaining is that can agriculturally receive and allow to make
Insecticides adjuvant.
Further, 2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone preferred weight portion rate in the composition are 35:1.
Bactericidal composition of the present invention can be prepared into suitable agricultural production any formulation for using, and relatively good formulation has
Suspending agent, dispersible oil-suspending agent, aqueous emulsion, microemulsion, water dispersible granules, ultra low volume liquids etc..
Compared with prior art, the advantage of the invention is that:
1st, 2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone compounding have significant synergistic function, are used alone than single dose and significantly improved
To the prevention effect of disease on crops.
2nd, 2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone two kinds of active components are compounded, and reduce Pesticide use amount, reduce use cost, are subtracted
The light pollution to environment.
3rd, 2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone two kinds of active components are compounded, and the mechanism of action is different, and action site increases, and delays
Pathogen drug-fast generation, increased the service life of agricultural chemicals.

Test method:With reference to《Farm-chemical indoor determination test rule NY/T1156.2-2006》, using Plating.
Statistical analysis is carried out with DPS statistical analysis softwares, the EC of each medicament is calculated50, and mixture is calculated according to the abundant methods of Sun Yun
Co-toxicity coefficient (CTC values), co-toxicity coefficient (CTC) >=120 shows as synergistic effect;Co-toxicity coefficient (CTC)≤80 shows as short of money
Anti- effect;80 < co-toxicity coefficients (CTC) < 120 show as summation action.
Table 1,2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone compound the Toxicity Determination to wheat scab pathogen
As it can be seen from table 1 2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone are 100:1~1:It is malicious altogether when being compounded in the range of 1 (by weight)
Coefficient (CTC) is all higher than 120, illustrates to show synergistic function to wheat scab pathogen;2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone
80:1~10:When being compounded in the range of 1 (by weight), synergistic function is more notable, and co-toxicity coefficient (CTC) is 200
More than;2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone are with 35:1 (by weight) compounding, synergistic function is the most notable, and co-toxicity coefficient (CTC) reaches
It is 278.40 to maximum.It can be seen that, 2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone compounding have reasonability and feasibility.
Embodiment eight:2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone complex composition preparation prevent and treat the field test of wheat scab
In wheat scab early stage dispenser, per 7d dispensers 1 time, dispenser 2 times altogether.State of an illness radix, the 2nd are investigated before dispenser
A situation arises for 14d investigation disease after secondary dispenser, counts disease index, calculates preventive effect.
Table 2,2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone complex composition preparation prevent and treat the field test of wheat scab
From table 2 it can be seen that each 2-cyano-3-amino-3-phenylancryic acetate and benziothiazolinone complex composition preparation wheat scab is shown it is excellent
Different prevention effect, preventive effect is more than 80%, hence it is evident that be used alone higher than each single dose, especially (the 36% cyanogen alkene of embodiment one
Bacterium ester benziothiazolinone suspending agent) preventive effect of wheat scab is more protruded, preventive effect is up to more than 90%.Simultaneously in pilot survey
Do not find that each metrafenone and 2-cyano-3-amino-3-phenylancryic acetate complex composition preparation produce poisoning to wheat in journey.
In sum, the complex composition of a kind of 2-cyano-3-amino-3-phenylancryic acetate-containing of the present invention and benziothiazolinone, synergistic function
Significantly, it is used alone compared to each single dose and improves preventive effect, can effectively prevent and treat the head blight on wheat, the lasting period is long, wheat is pacified
Entirely, increase production obvious, be worth the popularization and application in agricultural production.
