Description
Technical field
The present invention relates to a kind of bactericidal compositions, and in particular to be a kind of killing containing benzo alkene fluorine bacterium azoles and matrine
Bacteria composition.
Background technology
Powdery mildew is a kind of worldwide disease occurred extensively, and chemical pesticide control powdery mildew, mesh are mainly used 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 effect reduces.
Benzo alkene fluorine bacterium azoles are a kind of pyrazole amide series bactericidal agents, by inhibiting on mitochondrial inner membrane in electron transport chain
Succinate dehydrogenase so that disease fungus can not generate energy via breathing, and then disintegrate 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.
Matrine is to fall noise made in coughing or vomiting leaf shrub kuh-seng by pulse family Sophora（Sophora flavescens Ait) root, stem and fruit
A kind of water-soluble alkaloid extracted through stringent technique, appearance are brown homogeneous liquid.Generally Banlangen,
Main component has matrine, oxymatrine, sophocarpine, N-Oxysophocarpine, Sophoridine etc..Platymiscium never poison, to tag
Based on have both stomach poison function, this product belongs to broad spectrum activity botanical pesticide to people and animals' low toxicity, true to downy mildew, powdery mildew, anthracnose etc.
Fungal disease has greater activity.
Present inventor has made intensive studies the recipe determination of benzo alkene fluorine bacterium azoles and matrine, finds benzo
Alkene fluorine bacterium azoles and matrine carry out mixture and are had obvious synergistic function in a certain range to powdery mildew, 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 matrine at present.
Invention content
The purpose of the present invention is to provide a kind of composition pesticides to powdery mildew with synergistic function, help to subtract
Few pesticide usage amount, the generation for delaying drug resistance, environmentally friendly safety.
Unresolved above-mentioned technical problem, the present invention adopt the following technical scheme that：A kind of synergetic pesticide composition, feature exist
In, active constituent include benzo alkene fluorine bacterium azoles and matrine, wherein benzo alkene fluorine bacterium azoles and the weight ratio of matrine are 1:60-
60:1, preferably 20:1-1：1.
Further, the weight ratio of active constituent is 0.5-80%, preferably 1-50% in the composition pesticide.
Further, the composition pesticide can be aided with suitable auxiliary element in formulations of pesticide processing and be processed into arbitrarily
A kind of formulations of pesticide, such as can be wettable powder, water dispersible granules, aqueous emulsion, microemulsion, suspending agent.
It is that each substance has mixed in composition that the composition of the present invention can be provided in the form of finished product preparation, can also be with
Unit dose form provides, and is directly mixed in proportion in bucket or tank 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.
The bactericidal composition of the present 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）After the composition compounding of the present invention, have 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 the composition of the present invention, while effectively prevention crop disease,
The generation that can delay pathogen drug resistance is conducive to the service life for delaying pesticide activity component；
（3）The composition preparation process of the present invention is simple, is suitble to promote and apply in actual production.

Two, Toxicity Determination
Subjects：Cucumber powdery mildew's pathogen
Test method：Experiment refers to People's Republic of China (PRC) professional standard NY/T 1156.11-2008《Pesticide indoor biological
Measure the 11st part of test rule fungicide：It prevents cucurbits powdery mildew and tests pot-culture method》, measured using pot-culture method.
Susceptible cucumber variety is sowed, it is spare that potting grows to 2 leaf periods.By prepared benzo alkene fluorine bacterium azoles and kuh-seng
Alkali liquor is dissolved with 0.1% Tween-80 aqueous surfactant solution and prepares concentration gradient.And it sets containing only solvent and surface-active
Agent and without containing effect ingredient processing make blank control.24 h after chemicals treatment, spray inoculation cucumber powdery mildew's pathogen spore suspension
Liquid.The process for preparation of spore suspension is as follows：It takes and covers with Powdery Mildew blade, with a small amount of Tween-80 surfactant that refuels
Sterile water washes down spore, double gauze filtering, and 1X10 is modulated into after microscopy5The suspension of a/mL.Inoculation is placed on thermostatic chamber
In, it is cultivated 7 days under the conditions of 24 DEG C of temperature.When blank control disease liquid rate reaches 80% or more, the state of an illness of getting a haircut everywhere is investigated in classification
Condition calculates the disease index and control effect of each processing.
Control effect is converted into probit value（y）, liquor strength（ug/mL）It 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 of medicament are calculated according to Sun Yunpei's Method（CTC）.Experiment knot
Fruit is shown in Table 1.
Indoor virulence test the result shows that, benzo alkene fluorine bacterium azoles and matrine are 1:60-60:It is white to cucumber in the range of 1
The prevention of powder disease shows as synergistic effect.Wherein, when benzo alkene fluorine bacterium azoles and matrine weight ratio are 20:1-1:It is malicious altogether when 1
140 or more, synergistic function becomes apparent from coefficient.
Three, field control effectiveness test
In order to further verify the practical application effect of the present invention, prevention cucumber is carried out using the medicament of the embodiment of the present invention
Powdery mildew field control effectiveness test.
Reagent agent：（1）11% benzo alkene fluorine bacterium azoles aqueous matrine solution；（2）10.5% benzo alkene fluorine bacterium azoles
Matrine water dispersible granule；（3）31% benzo alkene fluorine bacterium azoles matrine suspending agent；（4）2% benzo alkene fluorine bacterium azoles matrine is micro-
Emulsion；（5）Comparative example 1:10% benzo alkene fluorine bacterium azoles suspending agent；（6）Comparative example 2:0.5% aqueous matrine solution.
It 5 days after medicine, investigates within 10 days disease indexs and calculates preventive effect, test result is shown in Table 2.
From the above data, it can be seen that the preparation of embodiment 1-4 is apparent high to the field control effect of powdery mildew of cucumber
In the control effect of 10% benzo alkene fluorine bacterium azoles and 0.5% aqueous matrine solution, meanwhile, matrine due to having both, diseases prevention multi-effect,
Such as aphid, downy mildew, effectively preventing can also be obtained, composition of the invention can prevent or delay benzo alkene fluorine bacterium azoles
With the generation of the single active constituent drug resistance of matrine, moreover it is possible to reduce pesticide cost, can overcome single-activity after the two compounding
The undesirable problem of ingredient preventive effect can also reduce the usage amount of pesticide, reduce drug cost, and composition of the invention is into one
The development and application that step accelerates novel pesticide provide foundation, have important dissemination.
