Description
Technical field
The present invention relates to a kind of anti-plant virus agent of technical field of pesticide, preparation and the application of the concrete a kind of compound that relates to a kind of plant extracts for the anti-gourd vegetables viroses of plant and agriculture chemical compounding.
Background technology
The viroses of plant are the important diseases of a class that harm the crops, and, control difficulty great because of its harm has the title of plant cancer.Bring about great losses to agricultural, the loss of global annual crops is up to multi-million dollar throughout the year.In recent years, the viroses of plant endanger seriously day by day, especially to economic crops.Picture is such as the gourd, fruit and vegetable class plant such as pumpkin, custard squash, fragrant sponge gourd and flowers etc.The gourd vegetables plant can present more typical virus disease symptom after dying virus disease being arranged, shrinkage, deformity in various degree appears in incidence of leaf, the blade variable color, produce floral leaf, spot, arteries and veins band and yellow, and on blade, also present necrotic plaque and arteries and veins necrosis, at the downright bad bar of the normal appearance in the surface of stem and root, in addition, sugar-preserved gourd presents dark green and light green alternate pattern, surface irregularity, sugar-preserved gourd deformity.Picture is such as main gourd vegetables planting base-Qingpu District, Shanghai, plant and be implanted with a large amount of gourd vegetables such as fragrant sponge gourd, pumpkin and custard squash, cultivated area is up to 550 mu, and serious virus disease occured in this planting base in 2010, caused a large amount of gourd vegetables leaf-shrinkages, the melon and fruit deformity, in addition, this viroid disease spread speed is very fast, and the incidence of disease is almost up to 100%, greatly reduce like this Quality and yield of gourd vegetables, make plantation peasant household suffer tremendous economic loss.
In order effectively to control the gourd vegetables viroses of plant; researchers have adopted various prophylactico-therapeutic measuress such as shift of crops, breeding for disease resistance, prevention and control to pass virus mediator, attenuated strain cross protection etc.; also carried out the development of chemical agent and natural, synthetic anti-gourd vegetables plant virus agent; but up to the present; the medicament kind that is applied to gourd vegetables phytopathy murder by poisoning control is also few; mainly be morpholine biguanidine hydrochloride, crystal aerugo, octicin solution and mixed agent thereof; and effect is all undesirable, and dosage and cost constantly increase.In addition, chemical pesticide uses the problem such as caused a series of environment to cause people's great attention in a large number, for this reason, develops a kind of novel gourd vegetables Control of Plant Virus Disease medicament combination and seems very urgent.Wherein, from plant, seek the material with antiviral activity, become an important channel of current novel anti-gourd vegetables plant virus agent initiative.In addition, arbitrarily abandoning of current a large amount of agricultural wastes, not only caused the idle and waste of ample resources, but also caused certain burden to environment, therefore, the present invention utilizes agricultural wastes and chemical pesticide composite, when guaranteeing drug effect, greatly reduce the use of chemical pesticide, and realized the recycling of agriculture waste resource, fully idle resource is brought into play its due society and economy and be worth, realized agriculture sustainable development.
Summary of the invention
For the prior art above shortcomings, the object of the invention is to provide agricultural wastes have the anti-gourd vegetables viroses of plant at interior plant extracts and agriculture chemical compounding compound preparation and preparation and the application that include that a kind of efficient, low-residual, production cost are low, can greatly reduce the chemical pesticide usage amount.
According to an aspect of the present invention, a kind of compound preparation of the anti-gourd vegetables viroses of plant is provided, be active ingredient (40%～90%) by plant extracts and chemical pesticide, all the other are to allow in the agricultural chemicals to use and the conventional auxiliary material of acceptable (10%～60%) composition, and the weight percentage of described active ingredient component and shared active ingredient total amount is: the blue extract 5～50% of Song, garlic P.E 5～50%, albizzia julibrissin extract 2～40%, Imidacloprid 0.01～10%, antitoxin rich 0.01～5%.
Described Song blue (Isatis tinctoria L.) takes from the blue stem of Song, leaf, flower or its mixture.The blue extract of described Song is to clay into power after the blue oven dry of Song, again through lixiviate, to filter, and reduced pressure concentration obtains.
Described garlic (Allium sativum L.) is taken from stem, the leaf of discarding after garlic is pruned or gathers in the crops; Described garlic P.E is with claying into power after the garlic oven dry, again through lixiviate, filters, and reduced pressure concentration obtains.
Described silk tree (Albizia julibrissin D.) is taken from discarded branch, leaf or the root that silk tree is pruned or naturally comes off; Described albizzia julibrissin extract is with claying into power after the silk tree oven dry, again through lixiviate, filters, and reduced pressure concentration obtains.
Described Imidacloprid and the antitoxin rich commercial product that is.Wherein Imidacloprid generalization formal name used at school is called 1-(6-chloropyridine-3-pyridylmethyl)-N-Nitroimidazoline-2-base amine, antitoxin rich be 0.5% mushroom derived protein amylase.
Described conventional auxiliary material refers to promote extract dissolving or the solubilizer (tween, polyethylene glycol, neopelex, Potassium dodecylbenzenesulfonate etc.), emulsifier (odium stearate, lauryl sodium sulfate, APEO etc.) and/or the suspending agent that suspend, synergist (Tea Saponin etc.), bleeding agent (emulsifier BP etc.) etc.
According to another aspect of the present invention, the preparation method of the compound preparation of the above-mentioned anti-gourd vegetables viroses of plant is provided, be specially: respectively with the blue stem of Song, leaf, flower or its mixture and garlic are pruned or the rear discarded stem of results, leaf, the discarded branch that silk tree is pruned or naturally comes off, leaf, flower or its mixture, clay into power after the oven dry, with ethanolic solution as extraction solvent, lixiviate, filter, filtrate adopts the method for reduced pressure concentration to obtain respectively medicinal extract, and then add Imidacloprid and antitoxin rich, and add at last conventional auxiliary material, make the compound preparation of the anti-gourd vegetables viroses of plant of the present invention.
Preferably, described oven dry refers to: 30-50 ℃ of lower oven dry.
Preferably, described powder refers to: 20-40 purpose granulated powders.
Preferably, described ethanol refers to ethanolic solution or the absolute ethyl alcohol of 10%-95%v/v, and its consumption is 10-20 times of powder quality.
Preferably, described lixiviate, its time is 1-7 days.
Preferably, described reduced pressure concentration refers to: the crude extract that obtains after the lixiviate is vacuumized decompression to-0.1 atmospheric pressure and places 30-80 ℃ of lower water-bath, make crude extract simmer down to medicinal extract.
According to a further aspect of the invention, provide the application of the compound preparation of the above-mentioned anti-gourd vegetables viroses of plant, refer to: under stirring at normal temperature, water is added in the compound preparation, its active ingredient that is diluted to preparation is accounted for spray after the concentration of 0.5-5wt% and use.
It is sick that the compound preparation of the anti-gourd vegetables viroses of plant of the present invention can be applied in the fragrant sponge gourd of control, pumpkin, custard squash etc. gourd vegetables Plant virus.
Compared with prior art, the present invention has following beneficial effect:
(1) synergy can strengthen the Antiphytoviral effect on the one hand between the primary raw material of composition product of the present invention, on the other hand because the acting in conjunction of the active ingredient of the different mechanisms of action can delay the pesticide resistance generation of medicament; In addition, can also greatly reduce the use of chemical pesticide.
