Agent, stabilizer, antifreezing agent, thickener etc. and it is other be beneficial to active ingredient in the formulation stablize and drug effect play material, this
A little auxiliary agents are to commonly use in pesticidal preparations or allow the various composition used, are not particularly limited, specific composition and dosage can bases
Recipe requirements are determined by testing.
In one embodiment, the composition pesticide is configured to aqueous suspension agent, dispersible oil-suspending agent, water and milk
Agent, microemulsion, wettable powder, suspension seed-coating agent, water dispersible granules or missible oil.
In one embodiment, the composition pesticide is withered for the powdery mildew, rust, spot for preventing and treating cereal or beet
Disease, banded sclerotial blight, the powdery mildew of pomaceous fruits, shot hole, uncinula necator, and for method for treating seeds to prevent and treat bunt
The fungal diseases such as disease, head smut and smut.
In one embodiment, the composition pesticide has plant health effect, for increasing crop yield, carrying
High crop products quality.
The present invention has following remarkable result and advantage：
1. alkene oxime amine is methoxy acrylic bactericide, tetraconazole is triazole bactericidal agent.The two has not
With mechanism of action, without cross resistance, can Synergistic, reduce and single dose be used alone.
2. alkene oxime amine has health care yield increasing effect with tetraconazole composition, crop early ageing can be prevented, promote volume increase,
Improve product qualities.
Inventor carries out alkene oxime amine and tetraconazole mixture to rice Rhizoctonia solani co-toxicity test.Specifically
Test situation and result are as follows：
Using mycelial growth rate method.Tetraconazole and alkene oxime amine mixture and tetraconazole, the place of alkene oxime amine single dose
It is 1,0.5,0.25,0.125 and 0.06mg/l to manage concentration, separately sets the blank control of not adding medicine.Totally 54 processing, are often handled
3 repetitions.
The AEA culture mediums melted are cooled to 60-70 DEG C, by design concentration above add quantitative pharmacy, be configured to containing
The toxic culture medium of different doses, after its is sufficiently cool, a diameter of 5mm Rhizoctonia solani Kuhn bacterium piece is inoculated with, is then placed into
Cultivated in incubator, result investigation is carried out after 48 hours.
The colony diameter often handled is measured during investigation respectively, then calculates bacteriostasis rate.
According to bacteriostasis rate, virulence regression equation and EC are obtained50Value, seven are calculated by Sun-Johnson toxicity indexes calculating method
The co-toxicity coefficient of individual proportioning mixture.
The alkene oxime amine of table 1. is with tetraconazole composition to joint toxicity measuring result in rice sheath blight disease germ room
From table 1 it follows that alkene oxime amine has preferable prevention effect to rice sheath blight disease with tetraconazole mixture,
Seven for EC of the trial than mixture50Value is between 0.07mg/L-0.22mg/L；Alkene oxime amine and tetraconazole 20:1、10:1、5:
1、1:1、1:5、1:10 and 1:The co-toxicity coefficient of 20 7 proportioning mixtures is more than 120, shows obvious synergistic effect.Illustrate alkene oxime
Bacterium amine has reasonability and feasibility with tetraconazole mixture preventing and treating rice sheath blight disease.
Inventor carries out alkene oxime amine and tetraconazole mixture to wheat powdery mildew pot experiment.Specific test situation
And result is as follows：
Using seedling pot-culture method.2 leaf phase potted plant wheat seedlings of growth selection neat and consistent, are being made by designing quality concentration
Foliar spray processing is carried out on thing spraying machine, places after dispenser and is dried in fume hood.Wheat powdery mildew kind is inoculated with after 24 hours,
Wheat after inoculation is placed in phjytotron (temperature：18 DEG C of night of 22 DEG C of daytime, humidity：70%) cultivate 1 day, then move to greenhouse training
Support.
6 days investigation preventive effects after inoculation, 10 plants are investigated per basin, the 1st blade of every plant of investigation.Divide 6 grades of records, calculating is referred to disease
Preventive effect.Disease scale standard (in units of blade), with reference to pesticide field efficacy medicine test criterion bactericidal agent for preventing and treating Cereal white powder
Sick (GB/T17980.22-2000).
The alkene oxime amine of table 2. is with tetraconazole composition to joint toxicity measuring result in wheat powdery mildew room
According to bacteriostasis rate, virulence regression equation and EC are obtained50Value；According to the abundant co-toxicity coefficient methods of Sun Yun (CTC), (this is science
Upper conventional formulation) two kinds of active constituents of medicine difference mixed ratios of evaluation synergy type：If co-toxicity coefficient is more than 120,
Show there is synergistic effect；If less than 80, antagonism is shown to be；Between 80~120, summation action is shown to be.
From Table 2, it can be seen that alkene oxime amine has preferable prevention effect to wheat powdery mildew with tetraconazole mixture,
Seven for EC of the trial than mixture50Value is between 0.53mg/L-0.95mg/L；Alkene oxime amine and tetraconazole 20:1、10:1、5:
1、1:1、1:5 and 1:The co-toxicity coefficient of 10 6 proportioning mixtures is more than 120, shows obvious synergistic effect.1:20 proportioning mixtures
Co-toxicity coefficient be less than 120, show summation action.Illustrate that alkene oxime amine has with tetraconazole mixture preventing and treating rice sheath blight disease
Reasonability and feasibility.
