Abstract
The invention discloses and a kind of dislike bacterium azoles and the bactericidal composition of fluorine thiazole pyrrole ethyl ketone containing dichloro, dislike bacterium azoles and fluorine thiazole pyrrole ethyl ketone and conventional auxiliary element including active component dichloro, it is 10:1～1:2 that dichloro dislikes the weight ratio of bacterium azoles and fluorine thiazole pyrrole ethyl ketone.Great number of indoor and outdoor experiments show that after being compounded, the bactericidal composition of the present invention multiple diseases to the growth that harms the crops, especially to by the microbial disease of Oomycete cause of disease, there is significant synergistic function, decrease Pesticide use amount simultaneously, reduce pesticide residual quantity on crops, alleviate the pollution to environment, delayed the drug-fast generation of pathogen, added the Pesticide use life-span.
Description
Technical field
The present invention relates to pesticide sterilizing composite and application thereof, specifically dislike bacterium azoles and fluorine thiazole pyrrole with dichloro
Ethyl ketone is the binary complex that active component is compounding, is mainly used in the preventing and treating of disease on crops.
Background technology
Dichloro dislikes bacterium azoles, molecular formula: C9H6Cl2N2O3S, molecular weight 293.1, to by the microbial disease of Oomycete cause of disease such as
Late blight, downy mildew etc. have good prevention effect.
Fluorine thiazole pyrrole ethyl ketone (oxathiapiprolin), is piperidyl thiazole isoxazolines antibacterial, and its structure includes
Isoxazole ring, pyrazole ring and thiazole ring, mechanism of action is suppression oxygen steroid binding proteins (OSBP), to Rhizoma Solani tuber osi, Fructus Vitis viniferae, vegetable
By the microbial disease of ovum, there is remarkable preventive effect with on other Featured crops.
Pesticide individually long-time uses continuously and easily produces resistance risk and consumption increases risk, so increase cost and
Carrying capacity of environment, and the compositions with notable synergistic function is filtered out by agriculture chemical compounding, Pesticide use can not only be reduced
Amount, the use cost that reduces, minimizing resistance risk, moreover it is possible to reduce potential environmental risk.
Summary of the invention
Bacterium azoles and the bactericidal composition of fluorine thiazole pyrrole ethyl ketone, this Bactericidal composite is disliked containing dichloro it is desirable to provide a kind of
Thing has significant synergistic function, can be used for multiple diseases on crops, especially by the microbial disease of Oomycete cause of disease
The preventing and treating of evil.
Technical scheme: a kind of containing dichloro evil bacterium azoles and the bactericidal composition of fluorine thiazole pyrrole ethyl ketone, including active component two
Chlorine dislikes bacterium azoles and fluorine thiazole pyrrole ethyl ketone and conventional auxiliary element, and it is 10:1 that dichloro dislikes the weight ratio of bacterium azoles and fluorine thiazole pyrrole ethyl ketone
～1:2, dichloro dislikes bacterium azoles and fluorine thiazole pyrrole ethyl ketone gross weight percentage composition in the composition is 1%～85%, and remaining is agriculture
Medicine allows use and acceptable auxiliary element.
Preferably, dichloro dislikes bacterium azoles and fluorine thiazole pyrrole ethyl ketone weight ratio in the composition is 8:1～1:1.
Described auxiliary element is solvent, emulsifying agent, wetting agent, dispersant, stabilizer, antifreezing agent, thickening agent, disintegrate
Agent, defoamer, penetrating agent, macromolecule cyst material, synergist, preservative and filler etc. are all conventional in pesticidal preparations or permit
Being permitted the composition used, be not particularly limited, concrete composition and consumption are determined by test according to recipe requirements.
Bactericidal composition of the present invention can be prepared as the multiple application forms being suitable in plant production using, reasonable dose
Type has microcapsule suspending agent, suspending agent, aqueous emulsion, microemulsion, water dispersible granules, wettable powder and cream.
The production technology of the various application forms of described bactericidal composition all belongs to existing known technology, does not repeats them here.
Bactericidal composition of the present invention can be used for multiple diseases on crops, especially by the microbial disease of Oomycete cause of disease
Preventing and treating.
Compared with prior art, it is an advantage of the current invention that:
1, dichloro dislikes bacterium azoles and fluorine thiazole pyrrole ethyl ketone compounds and has significant synergistic function, is used alone than single dose
Significantly improve the prevention effect of disease on crops.
2, dichloro dislikes bacterium azoles and fluorine two kinds of active component of thiazole pyrrole ethyl ketone compound, and decreases Pesticide use amount, reduces and make
With cost, alleviate the pollution to environment.
3, dichloro dislikes bacterium azoles and fluorine two kinds of active component of thiazole pyrrole ethyl ketone compound, and the mechanism of action is different, action site
Increase, delayed the drug-fast generation of pathogen, added the service life of pesticide.

Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theory toxicity index (TTI)] × 100.
According to the NY/T11547.7-2006 insecticide combination effect criteria for classifying: co-toxicity coefficient (CTC) >=120 shows as increasing
Effect effect；Co-toxicity coefficient (CTC)≤80 shows as antagonism；80 ＜ co-toxicity coefficient (CTC) ＜ 120 show as summation action.
Table 2, dichloro dislike bacterium azoles and the fluorine thiazole pyrrole ethyl ketone indoor virulence to cucumber downy mildew pathogenic bacterium Cuba artificial downy mildew
Measurement result
Compound in the range of 10:1～1:2 (by weight) from table 2 it can be seen that dichloro dislikes bacterium azoles and fluorine thiazole pyrrole ethyl ketone
Time, co-toxicity coefficient (CTC) is all higher than 120, and cucumber downy mildew pathogenic bacterium Cuba artificial downy mildew is all shown synergistic function；
Dichloro evil bacterium azoles and fluorine thiazole pyrrole ethyl ketone are in the range of 8:1～1:1 (by weight), and synergistic function is the most notable, altogether poison
Coefficient (CTC) is all more than 200；Dichloro is disliked bacterium azoles and fluorine thiazole pyrrole ethyl ketone and is compounded with 4:1 (by weight), and synergistic function is
For significantly, co-toxicity coefficient (CTC) is 254.69.Visible, dichloro dislikes that bacterium azoles and fluorine thiazole pyrrole ethyl ketone are compounding has reasonability and can
Row.
In sum, what the present invention provided is a kind of containing dichloro evil bacterium azoles and the bactericidal composition of fluorine thiazole pyrrole ethyl ketone, association
Notable with potentiation, compared with existing unitary agent, on preventing and treating crops, the effect of disease significantly improves, and pacifies crops
Entirely, popularization and application in agricultural production it are worth.
