Description
Technical field
The invention belongs to composition pesticide fields, and in particular to be a kind of sterilization comprising captan and isopyrazam
Composition and its purposes for preventing corps diseases.
Background technology
Powdery mildew is widely distributed in China, especially prevalent to the harm of dicotyledon, and when powdery mildew occurs, host is aggrieved
Position growth is suppressed, and gradual chlorisis turns yellow, and it is dried-up to last full leaf withered spot occur, makes plant early withered when serious.After disease
In the mould layer of white powder shape be made of mycelia and conidium, often there is the granular cleistothecium of many scattered black, and with this in phase
Overwintering, secondary spring carries out First aggression with ascospore.Powdery mildew is once occur, and spread speed is very fast, one Growing season of crops
It is energy saving to be repeatedly subjected to infect.Powdery mildew makes the crop products such as China's wheat, cucumber, grape therefore, prevent by extreme loss
The generation for controlling powdery mildew is significant to agricultural production.
Captan also known as Cape Town are the protective fungicide of trichloro-methylthio class wide spectrum, have certain treatment concurrently and make
With captan is a kind of lower toxicity broad spectrum protection bactericidal pesticide, can prevent a variety of diseases of the crops such as apple, pears, strawberry, grape
Evil has the function of that control effect is good, poisoning is small, appropriate using also with stimulation plant growth.Its main function mechanism is resistance
Disconnected disease fungus respiratory can also reduce the content of atriphos in pathogen so as to prevent germ is conidial from dissipating
It puts.It is mainly used for spraying, can also makees seed treatment, infusion product after harvest carries out soil treatment before sowing or before plant.For
The ring spot of prevention fruit tree, vegetables, flowers and other industrial crops etc., scab, downy mildew, powdery mildew, anthracnose, grey mold
Disease, early blight, late blight etc..The activity of the compound is good, still, sometimes and unsatisfactory in low rate of application.Its
To a variety of fungal diseases there is preferable control effect, but when preventing bacterium and fungal disease simultaneously, seem insufficient.And
Captan applicating history is long, and resistance problem is very prominent.Therefore, select other efficient germicides compound therewith be resist it is anti-
Property, delaying drug resistance development, extend an important channel of its service life.
Isopyrazam is the pyrazole amide series bactericidal agent researched and developed by Syngenta Co., Ltd, by inhibiting in mitochondria
Succinate dehydrogenase on film in electron transport chain so that disease fungus can not generate energy, and then disintegrate germ via breathing
Growth, which is used alone of high cost and easily pathogenic opportunistic pathogen generates resistance risk.
Either captan or isopyrazam, continuous use can cause drug effect to reduce, so as to cause usage amount into one
Step increases, and is unfavorable for the sustainable development of environment.It is one of measure to solve the above problems by pesticide activity component compounding.Without
If certain synergistic effect can be shown after being compounded with pesticide activity component, it is possible to reduce the use of pesticide activity component
Amount improves control effect, if the two kinds of active components mechanism of action is different, can also delay the generation of pathogen drug resistance, favorably
In the service life for extending pesticide activity component.Therefore, when screening obtains that there is the composition pesticide of synergistic function to become
One of hot research field of lower research, since the screening of composition pesticide needs to select from a large amount of pesticide activity component
Two or more is arrived, in addition to this, it is also necessary to a large amount of toxicity be coordinated to measure and measured with field efficacy, screening obtains
Composition pesticide not a duck soup with synergistic function.
Invention content
It is an object of the invention to against the above deficiency, provide a kind of bactericidal composition, the bactericidal composition prevention effect
Fruit is good, can reach apparent synergistic function after at low cost and the two compounding.
Another object of the present invention is to provide a kind of application of the pesticide sterilizing composite, the pesticide sterilizing combination
Object is particularly suitable for the oomycetes disease of the vegetables such as prevention melon and fruit class, Cereal, fruit tree, especially powdery mildew, downy mildew etc..
In order to achieve the above object, the present invention adopts the following technical scheme that：
A kind of Synergistic bactericidal composition, its active ingredient include captan and isopyrazam, wherein, captan and pyrrole
The mass ratio of azoles naphthalene bacterium amine is 1:5-50：1, preferred mass ratio is 1:1-10：1.
Preferably, in Synergistic bactericidal composition of the invention, the weight percentage of composition shared by active ingredient is 20-
80%, preferably 30-60%, remaining is conventional auxiliary element in Pesticide formulation, for example, can be solvent, emulsifier,
One kind or one kind in synergist, wetting agent, stabilizer, dispersant, thickener, pH adjusting agent, antifoaming agent, antifreeze, filler
Above mixing.
Further, for ease of use, Synergistic bactericidal composition of the invention can also add in other in preparation process
Agricultural active ingredient including but not limited to adds in other fungicides, insecticide, nematicide, kills harmful animal preparation, kills
Injurious weed agent, synergist, safener, fertilizer etc..
Further, Synergistic bactericidal composition of the invention can be by by active constituent and auxiliary agent, solvent and/or other
Carrier is prepared by mixing into any type of preparation used in suitable agricultural production, and the type of preparation includes but not limited to, breast
