Abstract
The invention provides an antibacterial composite adopting matrine and triazole fungicide, which includes an effective active component, a synergist, metal salt and a solvent, wherein the effective active component is a mixture of two effective active components A and B; the ratio of mass fractions of the two effective active components A and B is 60:1 to 1:60; A is matrine, and B is one selected from diniconazole, triadimenol and biphenyl triadimenol as triazole fungicide. The method for preparing the antibacterial composite includes the following steps: adding the matrine, triazole fungicide, synergist and metal salt in parts by mass in the solvent sequentially, and uniformly stirring. Compared with the prior art, the antibacterial composite adopting matrine and triazole fungicide can effectively eliminate diseases, and remarkably postpones the resistance to drugs of diseases, solves the problem of poor fast-acting performance of natural pesticides in virtue of the combination of natural pesticides and chemical pesticides, alleviates pollution to the environment and remarkably reduces the preparation cost.
Description
Technical field
The present invention relates to pesticide field, relate in particular to the bactericidal composition of a kind of matrine and triazole bactericidal agent.
Background technology
Matrine, is a kind of botanical pesticide, and molecular formula is C
15h
24n
2o, structural formula is as follows:
Matrine has the feature of specificity, natural sex, only to specific biological generation effect, in the Nature, can decompose rapidly, and end product is carbonic acid gas and water.Main by inhibitions, regulate and control bacterial growth, divide synthesizing of associated protein, block its division and growth, and with intracellular combined with protein, cause cytoplasm pyknosis, disintegration and make thalline death.But as botanical pesticide, matrine drug effect is slow, and due to extraction process complexity, preparation research is also in reduced levels, and therefore the relative chemical pesticide of price is higher, and it is larger that it applies difficulty.
Triazole bactericidal agent is organic heterocyclic compounds, is the class efficient germicide having developed since the seventies, and in its chemical constitution, common feature is on main chain, to contain hydroxyl (ketone group), substituted-phenyl and 1,2,4-triazole group.This class medicament, except to oomycetes non-activity in Mastigomycotina, all has activity to the pathogen of Ascomycotina, Basidiomycotina and Deuteromycotina, and its mechanism of action, for to affect sterols biosynthesis, is damaged somatic cells film function.Triazole pesticide except bacteriostasis, also to plant there is the physiological potency of adjusting, change conjugated group, the desinsection of getting back, activity of weeding.This series bactericidal agent is widely used, mode of action bactericide different from the past, and its biologically active is very potential.Alkene azoles alcohol (formula I), Triadimenol (formula II) and Bitertanol (formula III) etc. are the new bactericide kind of triazole type that recent year is produced and applied.
In actual application, the long-term single dose of triazole bactericidal agent is used, and the problem easily producing is that bacterium develops immunity to drugs, and dosage increasing then, preventive effect reduction, lasting period shorten, and are unfavorable for ecological protection.Usual way is exactly the kind composition of the different mechanisms of action to be carried out to the composite germ pesticide resistance of preventing and treating produce.According to practical application effect, judge this composite be synergy, add and or antagonism.Two kinds of active component mechanism of action differences in the present composition, mutually composite have good synergistic effect within the specific limits, and composite about matrine and triazole bactericidal agent, there is not yet at present relevant report at home and abroad.
Summary of the invention
In view of above-mentioned information, the object of the present invention is to provide the bactericidal composition of a kind of matrine and triazole bactericidal agent, can prevent the generation of disease drug resistance or delay the speed that pesticide resistance produces, and reduce use cost.
One of the object of the invention is to provide the bactericidal composition of a kind of matrine and triazole bactericidal agent, comprise effective active component, synergist, slaine and solvent, wherein effective active component is the mixture of A, two kinds of effective active components of B, the ratio of quality and the number of copies of A, two kinds of effective active components of B is 60:1～1:60, described A is selected from matrine, and B is selected from triazole bactericidal agent alkene azoles alcohol, Triadimenol, bitertanol a kind of.
Preferably, A, two kinds of effective active constituent mass portion rates of B are 30:1～1:30.
Preferably, A, two kinds of effective active constituent mass portion rates of B are 11:1～1:11.
Preferably, the content of A, two kinds of effective active components of B accounts for 1～80wt% of gross mass.
Preferably, the content of A, two kinds of effective active components of B accounts for 20～60wt% of gross mass.
Described synergist is glycerine, and glycerine has strong water sorption, can extend effective absorption phase of antibiotic, and can promote the cuticular hydration of leaf surface of plant, strengthens the water permeability of leaf table.
The content of described glycerine accounts for 2～10wt% of gross mass.
Described slaine is CuSO
4, metal ion can make antibiotic generate complex compound, and drug effect is significantly improved.
Described CuSO
4content account for 1wt% or the 2wt% of gross mass.
Two of the object of the invention is the preparation method of the bactericidal composition that matrine and triazole bactericidal agent are provided, and comprising: by described mass fraction, successively matrine, triazole bactericidal agent, synergist and slaine are joined in solvent, stir.
The bactericidal composition of matrine provided by the invention and triazole bactericidal agent compared with prior art, when effectively eliminating disease, can significantly delay the generation of disease drug resistance, and natural agricultural chemicals combines with chemical pesticide, solved the poor problem of natural agricultural chemicals quick-acting, alleviated the pollution to environment, preparation cost also significantly reduces.
