Description
Technical field
The present invention relates to a kind of bactericidal compositions, and in particular to when a kind of fluorine bacterium azoles of alkene containing benzo and pyrrole metsulfovax kill
Bacteria composition.
Background technique
Powdery mildew is a kind of worldwide disease occurred extensively, mainly uses chemical pesticide control powdery mildew, mesh in production
Before rely primarily on benzimidazole, triazole type, methoxy acrylic bactericide.However, killing for single kind is used for a long time
Microbial inoculum can make disease generate different degrees of resistance, and control efficiency reduces.
Benzo alkene fluorine bacterium azoles are a kind of pyrazol acid amide fungicide, by inhibiting on mitochondrial inner membrane in electron transport chain
Succinate dehydrogenase so that disease fungus can not generate energy via breathing, and then disintegrates the growth of germ, and the compound is independent
Higher operating costs and the generation for being easy hair resistance again, to reduce the service life of pesticide species.
Pyrrole metsulfovax is the novel acid amide fungicides of Mitsui chemical company research and development, is not only had to rust, sclerotiniose
Excellent activity also shows that preferable sterilization Mars to gray mold, powdery mildew and scab of apple, is now recommended for preventing and treating
The gray mold resistant to other fungicide and powdery mildew, but pyrrole metsulfovax is used alone for a long time, can equally generate very big
Resistance risk is unfavorable for effective control of disease.
Present inventor has made intensive studies the recipe determination of benzo alkene fluorine bacterium azoles and pyrrole metsulfovax, finds benzene
And alkene fluorine bacterium azoles and pyrrole metsulfovax carry out mixture and have obvious synergistic function in a certain range to a variety of fungies, pass through
Further research completes the present invention.
It there is no the relevant report of the complex composition of benzo alkene fluorine bacterium azoles and pyrrole metsulfovax at present.
Summary of the invention
The object of the present invention is to provide a kind of Synergistic bactericidal composition for being suitble to agriculturally use, helps to reduce and use
Dose, the generation for delaying pathogen resistance and reduction use cost.
In order to solve the above technical problems, the present invention adopts the following technical scheme: a kind of Synergistic bactericidal composition, feature exist
In active constituent contains benzo alkene fluorine bacterium azoles and pyrrole metsulfovax, wherein benzo alkene fluorine bacterium azoles and the weight ratio of pyrrole metsulfovax are 1:
50-50:1, preferably 1:10-10:1.
Further, the weight ratio of active constituent is 1-90%, preferably 10-70% in the bactericidal composition.
Further, the bactericidal composition can be processed into agricultural by preparation method conventional in Pesticide formulation
Any dosage form of upper permission, such as can be wettable powder, water dispersible granules, aqueous emulsion, microemulsion, water dispersible granules.
Composition of the invention can provide i.e. in composition that each substance has mixed in the form of finished product preparation, can also be with
Unit dose form provides, and is directly mixed in bucket or tank in proportion using preceding, is then diluted to required concentration.
Further, composition of the invention can also be added other agricultural active ingredients, for example, fungicide, insecticide,
The agricultural actives ingredient such as herbicide, fertilizer.
Bactericidal composition of the invention is suitable for preventing and kill off a variety of diseases such as powdery mildew of cucumber, tomato powdery mildew, powdery mildew of strawberry
Evil.
Compared with prior art, composition pesticide of the invention has the beneficial effect that
(1) it after composition of the invention compounding, has obvious synergistic function in a certain range, preventive effect and list
A active constituent is compared and is significantly improved；
(2) the active constituent mechanism of action is different in composition of the invention, while effectively preventing crop disease,
The generation that can delay pathogen drug resistance is conducive to the service life for delaying pesticide activity component；
(3) composition preparation process of the invention is simple, is suitble to promote and apply in actual production.

Two, indoor toxicity test
Subjects: cucumber percentage germ
Test method: test refers to People's Republic of China's professional standard NY/T 1156.11-2008 " pesticide indoor biological
Measure the 11st part of test rule fungicide: prevention and treatment cucurbits powdery mildew tests pot-culture method ", it is measured using pot-culture method.
Susceptible cucumber variety is sowed, it is spare that potting grows to 2 leaf periods.Benzo alkene fluorine bacterium azoles and pyrrole metsulfovax raw medicine point
It is not dissolved with dimethylformamide, then is dissolved with 0.1% Tween-80 aqueous surfactant solution.3 basins of every processing, 4 repetitions will
10 mL medical fluids are uniformly sprayed on blade face to whole wettings, spare to medical fluid naturally dry.And it sets containing only solvent and surfactant
And blank control is made in the processing without containing effect ingredient.24 h after chemicals treatment, spray inoculation cucumber powdery mildew's pathogen spore suspension.
The process for preparation of spore suspension is as follows: taking and covers with Powdery Mildew blade, with the sterile of a small amount of Tween-80 surfactant of refueling
Water washes down spore, double gauze filtering, is modulated into 1X10 after microscopy5The suspension of a/mL.Inoculation is placed in thermostatic chamber,
It is cultivated 7 days under the conditions of 24 DEG C of temperature.When blank control disease liquid rate reaches 80% or more, incidence is managed in classification investigation everywhere,
Calculate the disease index and control efficiency of each processing.
Control efficiency is converted into probit value (y), and liquor strength (ug/mL) is converted into logarithm (x), by minimum in terms of multiplication
Concentration EC in calculating virulence equation and inhibiting50, the toxicity index and co-toxicity coefficient (CTC) of medicament are calculated according to Sun Yunpei's Method.Test knot
Fruit is shown in Table 1.
The Toxicity Determination result show benzo alkene fluorine bacterium azoles and pyrrole metsulfovax when weight ratio is between 1:50-50:1,
Prevention and treatment powdery mildew of cucumber co-toxicity coefficient be all larger than 120, show preferable synergistic effect, especially when in 1:10-10:1, altogether
Malicious coefficient is all larger than 150, and synergistic effect becomes apparent from.
Three, field control effectiveness test
In order to further verify practical application effect of the invention, prevention and treatment cucumber is carried out using the medicament of the embodiment of the present invention
Powdery mildew field control effectiveness test.
Reagent agent: (1) 21% benzo alkene fluorine bacterium azoles pyrrole metsulfovax wettable powder；(2) 12% benzo alkene fluorine bacterium azoles
Pyrrole metsulfovax aqueous emulsion；(3) 33% benzo alkene fluorine bacterium azoles pyrrole metsulfovax water dispersible granules；(4) 30% benzo alkene fluorine bacterium azoles pyrroles
Metsulfovax suspending agent；(5) comparative example 1:10% benzo alkene fluorine bacterium azoles suspending agent；(6) comparative example 6:15% pyrrole fluorine bacterium ester suspending agent.
5 days after medicine, 10 days investigation disease indexs and preventive effect is calculated, test result is shown in Table 2.
It is preferable anti-that field control effectiveness test result shows that the composition of the embodiment of the present invention all has powdery mildew of cucumber
Effect is controlled, preferable lasting effect and quick-acting are shown.The composition is in the case where dosage reduces, 5 days, 10 after medicine
It preventive effect is significantly better than single active constituent.Meanwhile during test, reagent agent is to cucumber crop safety, no phytotoxicity hair
It is raw, to the beneficial organisms safety such as honeybee and world trichogramma, it is worth promoting and applying in production.
