Abstract
The invention discloses a bactericidal composition for crops. The bactericidal composition comprises the following components in percentage by weight: 0.5-25% of metalaxyl-M, 5-30% of copper rosinate, 5-20% of an emulsifier, and 30-50% an organic solvent, wherein the emulsifier is one or more of calcium alkyl benzene sulfonate, castor oil polyoxyethylene ether, fatty alcohol polyoxyethylene ether and Tween-60; and the organic solvent is one or more of xylene, super turpentine and heavy oil. 0.1-5wt% of azone may be also added into the components. The bactericidal composition disclosed by the invention comprises a chemical bactericide with double effects of prevention and treatment, and is a novel bactericidal composition prepared by compounding the chemical bactericide and a broad-spectrum and protective organic copper preparation, so that the drug effect is improved, the prevention and treatment objects are expanded, the generation of drug resistance is delayed, and the safety to environments and users is greatly improved.
Description
Technical field
The present invention is a kind of bactericidal composition for crops.
Background technology
Metalaxyl-M has significantly protection, treatment and the antibacterial of eradicant action as a kind of, is widely used
Preventing and treating in corps diseases.Copper rosinate, as a kind of wide spectrum, the antibacterial of protectiveness, is also widely used
Preventing and treating in corps diseases.Drug resistance is result in due to the most universal a certain antibacterial of single use
Generation, pharmacy control efficacy decline.Therefore develop a kind of efficient, wide spectrum, the pesticide that Drug resistance produces can be delayed
Preparation is current urgent problem.
Summary of the invention
The technical problem to be solved in the present invention is, the defect existed for prior art, proposes one for farming
The bactericidal composition of thing, it has potentiation, wide spectrum, can delay the feature that Drug resistance produces.
The technical solution of the present invention is, the percentage by weight composition of the described bactericidal composition for crops
For:
Wherein, described emulsifying agent refers to alkyl benzene calcium sulfonate, castor oil polyoxyethylene ether, aliphatic alcohol polyethenoxy base
One of ether, polysorbate60 are all kinds of or more than one, and organic solvent refers to the one of all kinds of of dimethylbenzene, excellent oil and heavy oil
Or more than one.
Also can add the azone (as synergist) that components by weight percent is 0.1%-5% in said components.
The chemical formula of described Metalaxyl-M is: N-(2,6-3,5-dimethylphenyl)-N-(Methoxyacetyl)-D-third
Amino acid methyl ester.
Metalaxyl-M is in two isomers of metalaxyl, is that having of first commercialization in the world is vertical
The antibacterial of body optically active, can be used for seed, soil treatment and stem and leaf and processes.Metalaxyl-M is a kind of high
Effect systemic fungicide, has significantly protection, treatment and eradicant action, downy mildew and the epidemic disease to multiple kinds of crops
Mildew has specially good effect, to the late blight of potato, downy mildew of garpe, Radix Betae epidemic disease, white rust of colza, the black shin of Nicotiana tabacum L.
Disease, Citrus foot rot, cucumber downy mildew, tomato blight, capsicum epidemic disease etc. and by phytophthora root rot cause various
20 plurality of plant diseases such as damping off and melon and fruit canker all have the prevention effect of brilliance.Its drug effect is than first frost
Spirit is high 2-10 times, greatly reduces dose；Fast 2 times of degraded in soil.
Described copper rosinate chemical formula is: 1,2,3,4,4a, 9,10,10a ,-octahydro-Isosorbide-5-Nitrae a, two
Methyl-7-(1-Methylethyl)-1 phenanthrene carboxylic acid copper.
Copper rosinate is the copper fungicide of a kind of wide spectrum, in recent years Citrus, Cotton Gossypii, Oryza sativa L., Fructus Mali pumilae, pears,
Large-scale promotion and application have been obtained on the multiple fungus of the various crop such as Fructus Vitis viniferae and the preventing and treating of some bacteriosis,
Citrus anthracnose, Cotton Gossypii angular leaf spot, bacterial leaf streak of rice, vegetable pythium rot, soft rot etc. there is specially good effect.
The present composition determines have broad-spectrum sterilization first-class and imitate through for a long time selecting excellent with repetition test
Really.It is listed in Tables 1 and 2 with the Experimental Comparison result of several antibacterial.
Table 1: several antibacterial virulence test result synopsis to phytophthora capsici
Bactericidal composition EC the most of the present invention contains 16% copper rosinate, 3% Metalaxyl-M, 2% azone
Table 1 illustrates that the co-toxicity coefficient of the disinfecting compositions of the present invention is significantly greater than 100, the virulence to pathogenic bacteria
The virulence summation used with Metalaxyl-M one pack system more than copper rosinate, has significant synergies.
Table 2: several antibacterial controlling experiment result synopsis to cucumber downy mildew
Bactericidal composition EC the most of the present invention contains 16% copper rosinate, 3% Metalaxyl-M, 2% azone
Table 2 illustrate the present invention by have prevention and chemical bactericide Metalaxyl-M and the wide spectrum for the treatment of double effects,
A kind of disinfecting compositions that protectiveness organic copper preparation copper rosinate prepares, two kinds of active component therein
Being mutually improved between effect, the Drug resistance of pathogenic bacteria reduces, and the bactericidal effect of compositions is apparently higher than each one pack system
Bactericidal effect during use, and fungicidal spectrum is wider；Not only reduce the usage amount of medicament, reduce the life of peasant
Produce cost, and substantially increase the safety to environment and user.
As known from the above, the present invention is a kind of bactericidal composition for crops, and it is will to have prevention and control
Treat chemical bactericide and wide spectrum, the compounding prepared a kind of disinfecting combination of protectiveness organic copper preparation of double effects
Thing, not only increases drug effect, expands controlling object, has also delayed drug-fast generation, and has been greatly improved
To environment and the safety of user.
Detailed description of the invention
Embodiment 1: first by disproportionated rosin potassium soap and copper sulfate, organic solvent, water, 60-80 DEG C of temperature
Under the conditions of carry out reacting prepared copper rosinate solution；About 60kg is added in 860kg copper rosinate solution
Metalaxyl-M crude oil (content is more than 90%), adds the emulsifying agent (alkyl benzene sulphonate of 80kg after mix homogeneously
One of calcium, castor oil polyoxyethylene ether, aliphatic alcohol polyethenoxy base ether, polysorbate60 are all kinds of or more than one),
After stirring, i.e. prepare the Bactericidal composite of 1000kg Metalaxyl-M of the present invention and copper rosinate
Thing.
Embodiment 2: first by disproportionated rosin potassium soap and copper sulfate, organic solvent, water, 60-80 DEG C of temperature
