Description

A kind of bactericidal composition containing orysastrobin and its application
Technical field
The present invention relates to a kind of composition pesticide, more particularly to a kind of bactericidal composition containing orysastrobin and its preventing and treating The application of disease, belongs to technical field of pesticide on crops.
Background technology
Rice blast and banded sclerotial blight are the diseases generally occurred on paddy rice, and each rice region of China has generation, blade of mainly causing harm, Stalk, fringe portion.Constantly substitute with China's rice varieties, hybrid paddy rice cultivated area expand and planting type change, the disease Harmful generation is presented and aggravates trend year by year.
Both at home and abroad for rice blast and banded sclerotial blight disease control, chemical pesticide control is mainly used in production, at present Rely primarily on the medicaments such as carbendazim, tricyclazole, jinggangmeisu, triazole type.These medicaments different journeys because long-term use has been generated The resistance of degree, prevention effect reduction, use cost rises.Therefore the new effective pesticide control of research and development is needed badly.
Orysastrobin, english common name：Orysastrobin, molecular formula：C18H25N5O5；It is a kind of methoxy acrylic acid Esters bactericide, mainly by suppressing the cytochrome b c1 in pathogen cell mitochondrial in respiratory pathways electron transport system Effect and and suppress the growth of pathogen, be currently used primarily in preventing and treating rice blast and banded sclerotial blight.The compound individually makes Opportunistic pathogen of causing a disease with high cost and easily produces resistance risk.
Tolprocarb, test code number:MTF-0301, is the carbamate sterilization of Mitsui chemical company exploitation Agent, mainly suppresses the growth of pathogen by suppressing the biosynthesis of pathogen ergosterol, especially has to rice blast excellent Different preventive effect.Mechanism of action is different from orysastrobin.
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, the relevant report of orysastrobin and tolprocarb is had no.
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 orysastrobin 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 orysastrobin, its active ingredient be orysastrobin and tolprocarb, both Mass ratio is 1:80~80:1, preferred mass ratio is 1:40~40:1, more preferably mass ratio is 1:10~10:1.
In the bactericidal composition gross mass percentage composition of active ingredient be 5%~85%, remaining be auxiliary agent, carrier and Other are 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, granule, missible oil, outstanding Floating agent, microemulsion, 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, leaf spot, the application of brown spot, are particularly well-suited to prevent and treat paddy rice rice blast The application of disease and banded sclerotial blight.
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 obvious Synergy 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.
Assays Example 1：Orysastrobin compounds the Toxicity Determination to rice blast fungus with tolprocarb Experiment
Subjects：Pyricularia oryzae (Phyricularia grisea)
Test method：
Experiment uses mycelial growth rate method.Orysastrobin active compound and tolprocarb active compounds are used into dimethyl formyl respectively Amine and acetone solution, then diluted with 0.1% Tween-80 aqueous surfactant solution.Told with containing appropriate acetone and 0.1% The aqua sterilisa of warm -80 surfactants is used as blank.4mL liquids are taken to be added to equipped with (the PDA cultures of the hot culture mediums of 36mL Base, 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 training Support base 10mL, each 4 repetition for the treatment of, horizontal rest, after cooling flat board.With diameter 5mm card punch from the confession for cultivating 5d Examination colony edge 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 ultra-clean work Sterile working is carried out as platform.Camera bellows culture in 25 ± 1 DEG C of constant temperature sterile culture case is placed on after treatment, right-angled intersection is used after 5d Method measures the colony diameter of each treatment respectively, 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 With when CTC >=120, then composition shows as synergistic effect.Toxicity Determination is the results detailed in Table 1.
