Description
Technical field
The present invention relates to pesticide sterilizing composite and its application fields, specifically with β-conglutin polypeptide and
Er Lv Evil bacterium azoles is the binary complex of effective active composition compounding, is mainly used in the prevention of disease on crops.
Background technology
β-conglutin polypeptide (Banda de Lupinus albusdoce, BLAD) is one kind in Lupinus albus kind
[i.e. (β-conglutin, belongs to 7S globulin to β-Conglutin to the storage protein that the specific period generates in sub- germination process
Family)] hydrolysis generate 20kDa polypeptide.β-conglutin polypeptide is easily dropped by common proteases quick bio in environment
Solution, therefore be difficult to remain in the environment, the safety of agricultural product can be improved.It is with completely new mechanism of action, with fungal cell membrane
On glycoprotein have high affinity, non-specific binding, high-affinity and non-can be carried out with the glycation product of glycoprotein
After specific binding, by with fungi reciprocation, cause fungal cell because of air-hole blockage/closing on many cell membranes, and
It is dead in a few houres；Also some other mechanisms of action have defined or have confirmed, such as observe it to powdery mildew germ
It may lead to Powdery Mildew cell disruption when effect because opening channel on cell wall and dead, have to some metal ions
There is sequestering activity, interferes microbial cell homeostasis.
Er Lv Evil bacterium azoles is Yi Zhong oxazole sulfone series bactericidal agents, and chemical name is：2- methyl sulfuryl -5- (2,4 dichloro benzenes
Base) -1,3,4- oxadiazoles are the fungicide of a kind of novel low-toxicity, safety.
The resistance problem of disease is a global problem in agricultural production, is always what agricultural science and technology worker paid close attention to
Key issues.With the increase for using the continuity year in year out of pesticide control disease, Pesticide use amount and not scientifical use
The factors such as pesticide cause the resistance getting worse of pathogen, the Species of Pathogens for generating resistance to be on the increase.Meanwhile high intensity
Use pesticide, result in Practice for Pesticide Residue in Agricultural Products it is exceeded, pollution environment and peasant's drug cost increase a series of problems, such as, no
Conducive to the sustainable development of agricultural.
The present inventor makes us during furtheing investigate β-conglutin polypeptide and Er Lv Evil bacterium azoles compounded formulas
It is surprised to find that β-conglutin polypeptide and Er Lv Evil bacterium azoles are compounded, to farming within the scope of certain compound proportion
Multiple diseases on object especially have significant synergies to diseases such as gray mold, powdery mildews, after further study, complete
At the present invention.
Invention content
The purpose of the present invention is to provide a kind of component is reasonable, the disease effect of synergistic effect significantly, on prevention crops
It is outstanding, the lasting period is long, drug cost is low, pathogen can be delayed to develop immunity to drugs, and to the bactericidal composition of Crop securify.
The sterilization containing β-conglutin polypeptide and Er Lv Evil bacterium azoles that another object of the present invention is to provide a kind of
Composite preparation dosage form.
Gray mold, the powdery mildew etc. that it is still another object of the present invention to provide above-mentioned bactericidal compositions on prevention crops
Purposes in disease.
Technical scheme of the present invention：To achieve the above object, present invention offer is a kind of containing β-conglutin polypeptide
With the bactericidal composition of Er Lv Evil bacterium azoles, effective active composition is made of β-conglutin polypeptide and Er Lv Evil bacterium azoles, β-
The weight ratio of conglutin polypeptide and Er Lv Evil bacterium azoles is 20:1~1:1, preferably β-conglutin polypeptide and dichloro
The weight ratio of Evil bacterium azoles is 15:1~1:1.
Further, in some embodiments, the weight ratio of preferably β-conglutin polypeptide and Er Lv Evil bacterium azoles is
8:1。
Further, in some embodiments, the weight ratio of preferably β-conglutin polypeptide and Er Lv Evil bacterium azoles is
6:1。
In bactericidal composition provided by the invention, the total weight percentage of β-conglutin polypeptide and Er Lv Evil bacterium azoles contains
Amount is 1%~85%, and the total weight percentage composition of preferably β-conglutin polypeptide and Er Lv Evil bacterium azoles is 10%~70%.
Bactericidal composition of the present invention can be prepared into the arbitrary dosage form used in suitable agricultural production, relatively good
Dosage form has aqua, wettable powder etc..
In various application forms prepared by bactericidal composition of the present invention, other than effective active composition, further include
Allow to use and the various auxiliary elements of acceptable in pesticide.
The auxiliary element includes but not limited to emulsifier, wetting agent, dispersant, bleeding agent, filler etc., is all pesticide
It commonly uses in preparation or allows the ingredient used, be not particularly limited, specific ingredient and dosage are true by testing according to recipe requirements
It is fixed.
The production technology of the various preparation formulations of bactericidal composition of the present invention belongs to existing known technology, herein no longer
It repeats.
Compared with the prior art, the advantages of the present invention are as follows：
1, β-conglutin polypeptide and Er Lv Evil bacterium azoles compounding have significant synergies, and individually make compared with single dose
With the control effect significantly improved to disease on crops.
2, β-conglutin polypeptide and Er Lv Evil bacterium azoles two kinds of active components compounding, reduce Pesticide use amount, drop
Low use cost, alleviates the pollution to environment.
3, β-conglutin polypeptide and Er Lv Evil bacterium azoles two kinds of active components compounding, the mechanism of action is different, makees
Increased with site, delayed the generation of pathogen drug resistance, increases the service life of pesticide.
Specific implementation mode
