Abstract
An antimicrobial composition containing cuprous oxide and pomegranate skin extract is provided by the present invention and relates to the technical field of bactericides. The cuprous oxide and the pomegranate skin extract are contained as effective ingredients, wherein the weight ratio of the cuprous oxide to the pomegranate skin extract is 1: 9 to 9: 1. The pomegranate skin extract is obtained through the following the steps: taking pomegranate skin and performing reflux extraction by using distilled water that weighs 4-6 times heavier than the pomegranate skin at temperature of 70-80 DEG C for 6-12 hours; filtering to obtain clarified water extract and residues; the residues performing the reflux extraction by using ethyl alcohol that weighs 4-6 times heavier than the residues at the temperature of 40-50 DEG C for 2-4 hours; filtering to obtain clarified alcohol extract; combining the clarified water with the clarified alcohol and concentrating to 5-10% of original volume to obtain the antimicrobial composition. The antimicrobial composition containing the cuprous oxide and the pomegranate skin extract provided by the present invention has a significantly protective effect on rice false smut and rice panicle rot disease by compounding the cuprous oxide and the pomegranate skin extract, and the protective effect can reach more than 90%.
Description
Technical field
The invention belongs to bactericide technical field, be specifically related to a kind of bactericidal composition containing cuprous oxide and pomegranate rind extract.
Background technology
The control of crop pest accounts for very large proportion in agriculture production cost, and along with the development bulk sterilization agent of science and technology continues to bring out, and drug effect is more and more higher.In actual use procedure, a lot of bactericide selectivity is strong, and target scope is narrower, is difficult to meet the requirement in control, needs various medicaments used in combination.But combined use of pesticides technology content is higher, peasant oneself is mixed often produces drug effect decline, poisoning generation.Therefore, be necessary composite effective bactericide to make built agent, reach object that is simple, high-efficiency prevention and control disease.
Cuprous oxide (Copper (I) oxide) is copper monovalence oxidation product, is Inorganic Copper series bactericidal agent.Its mechanism of action is, under plant surface acidity environmental condition, be disproportionated into bivalent cupric ion ,-SH ,-N in the copper ion be released and fungi or bacterial body internal protein
2the groups such as H ,-COOH ,-OH work, and cause germ dead.Cuprous oxide has protection and therapeutic action concurrently, is widely used in fungoid and the bacterial disease of the crops such as fruit tree, vegetables, flowers and paddy rice.Compare with other Inorganic Copper series bactericidal agent, it is high that cuprous oxide has copper ion effective content, the advantage comparatively safe to crop.Similar with other Inorganic Copper series bactericidal agent, it is to most bacterium class disease special efficacy, but to fungus disease limited efficiency.
Summary of the invention
For prior art Problems existing, the object of the invention is to design provides a kind of technical scheme containing the bactericidal composition of cuprous oxide and pomegranate rind extract.
Described a kind of bactericidal composition containing cuprous oxide and pomegranate rind extract, it is characterized in that containing active ingredient cuprous oxide and pomegranate rind extract, the weight ratio of described cuprous oxide and pomegranate rind extract is 1:9 ~ 9:1, described pomegranate rind extract is obtained by following steps: the distilled water refluxing extraction 6-12 hour at 70-80 DEG C getting granatum 4-6 times weight, filter, obtain primary water extract and filter residue, ethanol refluxing extraction 2-4 hour at 40-50 DEG C of filter residue 4-6 times weight, filter, obtain clarifying alcohol extract, merge primary water extract and clarification alcohol extract, be concentrated into the 5-10% of original volume, obtain.
Described a kind of bactericidal composition containing cuprous oxide and pomegranate rind extract, is characterized in that the weight ratio of described cuprous oxide and pomegranate rind extract is 1:7 ~ 7:1.
Described a kind of bactericidal composition containing cuprous oxide and pomegranate rind extract, is characterized in that the weight ratio of described cuprous oxide and pomegranate rind extract is 1:5 ~ 5:1.
Described a kind of bactericidal composition containing cuprous oxide and pomegranate rind extract, is characterized in that the weight ratio of described cuprous oxide and pomegranate rind extract is 3:2 ~ 4:1.
Described a kind of bactericidal composition containing cuprous oxide and pomegranate rind extract, is characterized in that the weight ratio of described cuprous oxide and pomegranate rind extract is 1:2 ~ 2:1.
Above-mentioned a kind of bactericidal composition containing cuprous oxide and pomegranate rind extract, by pomegranate rind extract with cuprous oxide is composite has remarkable preventive effect to rice green smut and Rice Panicle maize ear rot, preventive effect all can reach more than 90%.
Embodiment
The present invention is further illustrated below in conjunction with test example.
Embodiment 1
Get the former medicine of cuprous oxide and pomegranate rind extract, join sterile water and add surfactant, after ultrasonic process, through ultrasonic process, be mixed with suspension.Arrange according to mixture object and organize dosages distribution, 1:9,1:7,1:5,3:2,1:1,2:1,4:1,7:1,9:1 more, each proportioning is the mass ratio of two kinds of medicament active ingredients.
Wherein pomegranate rind extract is obtained by following steps: the distilled water getting granatum 5 times of weight refluxing extraction 10 hours at 75 DEG C, filter, obtain primary water extract and filter residue, the filter residue ethanol of 5 times of weight refluxing extraction 3 hours at 15 DEG C, filter, obtain clarifying alcohol extract, merge primary water extract and clarification alcohol extract, be concentrated into 8% of original volume, obtain final product.
