Description
Technical field
The present invention relates to a kind of composition pesticide, more particularly to a kind of bactericidal composition containing biphenyl pyrrole bacterium amine and its anti-
The application of disease on crops is controlled, belongs to technical field of pesticide.
Background technology
Rice blast and gray mold are a kind of worldwide diseases of extensive generation, respectively by the Magnaporthe grisea in fungi and grey grape
Spore causes.
It is main in production to use chemical pesticide control rice blast and gray mold, benzimidazole, hydroxyl are relied primarily at present
Miazines, phenoxyquinolines class, triazole type and methoxy acrylic bactericide.These medicaments have been generated because of long-term use
Different degrees of resistance, prevention effect reduction.In addition, triazole type medicament has suppression to make the growth of crop when dosage is big
With easily triggering poisoning.Therefore the new effective pesticide control of research and development is needed badly.
Biphenyl pyrrole bacterium amine, english common name：Bixafen, molecular formula：C18H12Cl2F3N3O, is a kind of new SDHI
Pyrazoles series bactericidal agent, is developed by Beyer Co., Ltd, belongs to succinate dehydrogenase inhibitors.The compound has well to various germs
Activity, such as powdery mildew, rust, leaf spot and gray mold.It is reported that the compound was listed in 2011, it is big in Australia at present
Leah, Chile, Estonia, Germany, Ireland, Lithuania, Ukraine and Britain obtain registration.The compound is used alone into
This is high and easily pathogenic opportunistic pathogen produces resistance risk.
Tolprocarb, molecular formula is C16H21F3N2O3, it is that the carbamates of Mitsui chemical company exploitation is killed
Microbial inoculum, there is excellent preventive effect to rice blast.Meanwhile, to pear scab, anthracnose of peach, peach grey scab and numerous fruit trees, vegetable
The crop such as dish gray mold, sclerotiniose are effective.
Different pesticide active ingredients is combined, synergistic effect significantly formula can greatly improve preventive effect, reduce medication
Amount and use cost, reduce residues of pesticides and environmental pollution.At present, biphenyl pyrrole bacterium amine report related to tolprocarb is had no
Road.
The content of the invention
It is an object of the invention to provide a kind of synergistic effect it is obvious, dosage is low, security good, be adapted to agriculturally produce
A kind of bactericidal composition containing biphenyl pyrrole bacterium amine for using.
To achieve the above object of the invention, the technical solution adopted by the present invention is：
A kind of bactericidal composition containing biphenyl pyrrole bacterium amine, its active ingredient is biphenyl pyrrole bacterium amine and tolprocarb, two
The mass ratio of person is 1:80~80:1, preferred mass ratio is 1:40~40:1, more preferably mass ratio is 1:10~10:1.
The gross mass percentage composition of the bactericidal composition active ingredient be 5%~85%, remaining be auxiliary agent, carrier and its
He is beneficial to the effective ingredient known substance that stabilization and drug effect are played in storage and use.
The bactericidal composition can be prepared with conventional method, i.e. the active compound containing effective ingredient and suitable auxiliary agent, can
To be processed into any formulation for agriculturally allowing, preferable formulation has wettable powder, water dispersible granules, missible oil, suspending agent, micro-
Emulsion, microcapsule suspending agent or suspension seed-coating agent.
The bactericidal composition preventing and treating crops on rice blast, gray mold, powdery mildew, rust, full rot, banded sclerotial blight,
Head blight, smut, root rot, scab, anthracnose, early blight, leaf spot, the application of brown spot, are particularly well-suited to preventing and treating
Rice blast and fruit tree, the application of eliminating vegetable botrytis.
Bactericidal composition of the present invention compared with prior art, can at least produce following beneficial effect：
(1) after two kinds of active ingredients are compounded according to the above ratio in the present composition, action site increases, with substantially increasing
Effect and lasting effect；
(2) production Pesticides usage amount and access times are effectively reduced, production and use cost is reduced, can be further effective
Reduce environmental pollution and residues of pesticides.
Specific embodiment
To make the object, technical solutions and advantages of the present invention become more apparent, with reference to embodiment in the present invention
Appearance is described further, but the present invention is limited to absolutely not these examples.
After the pesticide active ingredient mixing of different types of structure, typically exhibit three kinds of type of action, i.e. summation action, increase
Effect is acted on and antagonism, but is specially which kind of effect, it is impossible to predicted, only just be can know that by substantial amounts of experiment.

The aqua sterilisa of surfactant is used as control (CK).Take 4mL liquids be added to equipped with the hot culture mediums of 36mL (PDA culture medium, 45~
50 DEG C) conical flask in, after shaking up, pour into diameter 90mm glass culture dish rapidly, each culture dish pours into band medicine culture medium
10mL, each treatment 4 repetitions, horizontal rest, after cooling flat board.With diameter 5mm card punch from culture 5d for examination bacterium
The edge that falls cuts bacteria cake, and the one side with mycelia is connected on the malicious culture medium of band with pin is chosen, and all operations are in superclean bench
Carry out sterile working.Camera bellows culture in 25 ± 1 DEG C of constant temperature sterile culture case is placed on after treatment, using crossing method point after 5d
The colony diameter of each treatment is not measured, calculates average value, the mycelial growth inhibition rate of colony diameter.
Mode of application judges to use co-toxicity coefficient (CTC) method.The computing formula of co-toxicity coefficient is as follows：
Actual measurement toxicity index (ATI)=(standard agent EC50/ reagent agent EC50)×100
In theoretical toxicity index (TTI)=A medicaments ATI × mixture in the percentage composition+B medicaments ATI × mixture of A B hundred
Divide content
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100
When CTC≤80, then composition shows as antagonism, and as 80 ＜ CTC ＜ 120, then composition shows as being added and makees
