Abstract
The invention relates to a botanical plant-protecting agent and a preparation method thereof. The plant-protecting agent consists of salicylic acid, cinnamaldehyde or cinnamon oil, solvent, surfactant and water in a mass-volume ratio of 0.5-1.5:2.0-6.0:5.0-15.0:0.5-1.5: 80-220. The preparation method comprises: using organic solvent to dissolve salicylic acid in at room temperature or under water-bath conditions at 25 to 35 DEG C so as to obtain salicylic acid solution; adding an appropriate amount of cinnamaldehyde or cinnamon oil to the salicylic acid solution, stirring and mixing well; preparing surfactant into emulsion in a volume ratio between 0.5 and 1.0 percent by use of distilled water or tap water; and adding the obtained mixture liquid to the obtained emulsion, stirring and mixing well to obtain the plant-protecting agent. The plant-protecting agent is an environment-friendly plant-protecting agent, has the function of inducing the disease resistance of fruits and vegetables, and plays a certain role in sterilization. The agent has the advantages of simple preparation process, low cost and safety for crops, people and livestock, and ensures that pathogenic bacteria are not easy to have drug resistance after application.
Description
Technical field
The present invention relates to a kind of plant protection product, be specifically related to a kind of environmental protection, improve the fruits and vegetables disease resistance, improve plant resource plant protection product of fruits and vegetables outward appearance and quality and preparation method thereof, belong to the control of crop disease technical field.
Background technology
The weather of China's south warm moist often helps growing of pathogen, in order to reduce the generation of crop pest, the peasant uses chemical pesticide frequently, in large quantities, yet using chemical pesticide in a large number makes germ develop immunity to drugs easily, greatly reduce control efficiency, bring residue of pesticide and food-safety problem simultaneously inevitably.Fruits and vegetables is an indispensable food source in people's daily life, also is the most serious crop of residue of pesticide, and the food security incident happens occasionally.Simultaneously, fruits and vegetables is China peasant's an important source of finance, because residue of pesticide exceed standard and restricted the fruit and vegetable food outlet, stockpiling of unsold product, the peasant phenomenon that Higher output is not accompanied by a higher income is very general.Therefore, seek a kind of plant protection product of environmental protection, reduce the amount of application of the chemical pesticide of fruits and vegetables, improve the fruit and vegetable food quality, not only help guaranteeing food security, and help increasing foreign exchange earnings from exports, improving farmers' income.
Plant is the natural treasure-house of bioactive compound, and wherein many times biochemical material has desinsection or biologically active such as antibacterial, and has environmental friendliness, active characteristics such as various, in agricultural, pharmaceutically have important research and utilization to be worth.(SaLicyLicacid is a kind of phenolic compound that vegetative kingdom extensively exists SA) to salicylic acid, is the signal of interest molecule of plant disease-resistant reaction.In recent years, salicylic acid more and more is subjected to people's attention in the effect aspect the inducing plant disease resistance.With the external source salicylic acid as inducible factor, but evoking tobacco, potato, cucumber and paddy rice etc. make part and the system resistance of deposits yields to fungi, bacterium and virus disease.
Chinese cassia tree (Cinnamomum cassia PresL) is a kind of important Chinese herbal medicine, and it is fiery supporing yang to have benefit, eliminating cold to stop pain, the function of warming meridian, be used for the treatment of impotence, frequent micturition, postpartum the retention of urine, cirrhotic ascites, asthma, Bronchopneumonia, aphtha, baby diarrhea, children's hernia, rheumatism etc.China's Chinese cassia tree output accounts for more than 80% of world's Chinese cassia tree output, and Guangdong, Guangxi two province's Chinese cassia tree output account for more than 95% of China's Chinese cassia tree output, at present Researches on Cinnamomum cassia Presl are mainly concentrated on the medical science pharmacology.In the Chinese cassia tree except that containing some carbohydrate, also contain abundant cinnamon oil, its main component is a cinnamic acid, and cinnamic acid has very strong inhibition activity to pathogenic microorganism (especially fungi), has important research and using value in botanical fungicide exploitation and disease drug resistance improvement.
From the viewpoint of integrated pest management, avoid and alleviate causing harm of germ mainly containing three measures, the one, improve the resistance of crop, the 2nd, reduce pathogeny, the 3rd, create an environment that is unfavorable for that disease is popular.If in the control of disease simultaneously from the resistance that improves crop, suppress to set about considering aspect two of the growth of pathogenic bacteria, perhaps will reach the effect of getting twice the result with half the effort.Plant resource active substance salicylic acid, cinnamic acid have the effect of inducing crop resistance and suppressing pathogen respectively, but do not appear in the newspapers with the research that salicylic acid, cinnamic acid are developed plant protection product jointly.
Summary of the invention
The purpose of this invention is to provide a kind of environmental protection, have the fruits and vegetables of inducing disease resistance, and have the plant protection product of certain bactericidal action.
Another object of the present invention provides the preparation method of described plant protection product.
Above-mentioned purpose of the present invention is achieved by the following technical programs:
A kind of plant protection product of environmental protection; form by salicylic acid, cinnamic acid or cinnamon oil, solvent, surfactant and water; the mass volume ratio of each component is: salicylic acid: cinnamic acid or cinnamon oil: solvent: surfactant: water=0.5～1.5: 2.0～6.0: 5.0～15.0: 0.5～1.5: 80～220 (except that 1 part of salicylic acid is the 1g; other are volume ratio, and promptly 1 part is 1mL).
Described salicylic acid is pure for analyzing, and 1Guanghua Chemical Plant Co., Ltd., Guangdong produces.
Described solvent is ethanol, methyl alcohol, acetone, ethyl acetate.Preferred 95% ethanol (analyzing pure).
Described cinnamic aldehyde content is 98%, and Wuhan Yuancheng Technology Development Co., Ltd. produces.Cinnamon oil is raw material with the cassia, extracts the back extracted with diethyl ether with steam distillation and obtains, or with obtaining with conventional column chromatography for separation after the 95% ethanol lixiviate.
Described water is distilled water, running water or well water.
Described surfactant can be used Tween 80, agricultural newborn 600# etc.
The present invention provides the preparing process of described plant protection product simultaneously, and concrete preparation method is:
(1). with the salicylic acid organic solvent dissolution, make salicylic acid solution.(2). in salicylic acid solution, add an amount of cinnamic acid (or cinnamon oil), stirring and evenly mixing.(3). it is 0.5～1.0% emulsion that surfactant is made into volume ratio with distilled water or running water.(4). the emulsion with step (2) gained mixed liquor adding 0.5～1.0%, stir, mix.
Described preparation method all at room temperature carries out, and also can carry out under water-bath (25～35 ℃) condition.
Take into account inside and outside the plant protection product provided by the invention, have inducing anti-disease, the directly effect of sterilization simultaneously, after fruit, vegetables were used this plant protection product, disease obviously alleviated, fruit and vegetable food outward appearance, quality all be improved significantly.Said preparation also has the following advantages simultaneously:
1, this medicament process for preparation is simple, and conventional vessel is mixed and gets final product.
2, draw materials conveniently (cinnamic acid, salicylic acid be suitability for industrialized production), with low cost.
3, said preparation is to crop, people's herding safety.
4, pathogen is difficult for developing immunity to drugs.
