Abstract
The invention discloses a plant miticide and a preparation method and application thereof. The plant miticide consists of 40 to 80 percent by weight of chemical and 20 to 60 percent by weight of conventional adjuvants, wherein the components of the chemical material and the weight percentage contents of the components in the total amount of the chemical material are as follows: 5 to 40 percent of capsicum annuum linn extract, 2 to 40 percent of astragles propinquns schiscbk extract, 5 to 30 percent of photinia serrulata lindl extract and 2 to 30 percent of isatis indigotica fortune extract. The plant miticide utilizes agricultural wastes as main material resources, is completely prepared with the plant extracts, and has the advantages of high effectiveness, no residue, low production cost, economy, practicability, environment-friendliness and excellent comprehensive properties.
Description
Technical field
What the present invention relates to is a kind of plant acaricide of technical field of pesticide, and concrete a kind of utilization that relate to discarded pepper plant as plant resource miticide and preparation and the application in main material source.
Background technology
In recent years, the understanding clearly gradually of a series of environment, ecology and the human health problems of bringing for chemical pesticide along with people, development low toxicity, efficiently, becomes active demand to the biopesticide of environment, non-target organism safety.Wherein, from plant, find the material with killing pests and suppressing bacteria activity, become the Yi Tiao important channel of current novel miticide 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, realize recycling of agriculture waste resource, fully idle resource is brought into play to its due society and economy and be worth, realize the direction that sustainable development becomes Current Agricultural Development.
Tetranychus cinnabarinus (Tetranychus cinnabarinus) is a kind of important phytophagy tetranychid, there is the features such as individuality is little, breeding is fast, development duration is short, sphere of action is little, strong adaptability, mutation rate is high and easily develop immunity to drugs, be the pest communities of the most difficult control of generally acknowledging, its host plant is kind more than 100 nearly.Therefore, the miticide of finding highly effective and safe is imperative, and greatly develops the developing direction that plant resource miticide is current pesticide industry, in addition, plant resource miticide meets the requirement of current and the future of agriculture sustainable development, will have wide application development prospect.
At present to be generally that botanical pesticide and chemical pesticide carry out composite for the composite new drug development of botanical pesticide, reaches the effect of raising drug effect.The invention product that ZL200410021982.9 " agent of a kind of vegetalitas acaricide, Preparation method and use " mentioned as applied for a patent is curcumin chemical compounds, turmerone compounds, and turmeric essential oil, pyridaben is made preparation.Wherein pyridaben still accounts for significant proportion, and it belongs to moderate toxicity synthetic pesticide, although the impact of the aspects such as environment is slightly reduced when this technology ratio is used chemical pesticide separately, still can cause comparison severe contamination to environment.
Summary of the invention
Being of the object of the invention: for prior art above shortcomings, provide that a kind of efficient, noresidue, production cost are low, economical and practical, environmental friendliness, high comprehensive performance utilize agricultural wastes be main material source, completely by composite a kind of plant acaricide forming of plant extracts and its preparation method and application.
The present invention is achieved by the following technical solutions:
The invention provides a kind of plant resource miticide, bulk drug (40～80%) and conventional auxiliary material (20%～60%), consist of, the weight percent content of its bulk drug component and shared bulk drug total amount thereof is: pepper extract 5～40%, Fructus Solani melongenae extract 2～40%, Chinese photinia extract 5～30%, woaded blue extract 2～30%.
Described capsicum (Capsicum annuum Linn) is taken from rear discarded stem, leaf or the root of pepper fruit results.Described pepper extract is that discarded stem, leaf or root after pepper fruit results clayed into power, lixiviate, and filtration obtains.
Described eggplant (Astragles propinquns Schiscbk) is taken from discarded stem, leaf or root after eggplant fruit harvest; Described Fructus Solani melongenae extract is that stem discarded after eggplant fruit harvest, leaf or root are clayed into power, lixiviate, and filtration obtains.
Described Chinese photinia (Photinia serrulata Lindl) is taken from Chinese photinia and is pruned the stem or the leaf that get off; Described Chinese photinia extract is Chinese photinia to be pruned to the stem or the leaf that get off clay into power, lixiviate, and filtration obtains.
Described woaded blue (Isatis indigotica Fortune) is taken from stem, leaf or the root of woaded blue.Described woaded blue extract is that the stem of woaded blue, leaf or root are clayed into power, lixiviate, and filtration obtains.
Described conventional auxiliary material, refers to solubilizer (tween, polyethylene glycol, neopelex, Potassium dodecylbenzenesulfonate etc.), emulsifier (odium stearate, lauryl sodium sulfate, APEO etc.) and/or the suspending agent that can promote extract to dissolve or suspend, synergist (Tea Saponin etc.), bleeding agent (emulsifier BP etc.) etc.
The present invention relates to the acaricidal preparation method of above-mentioned plant resource, be specially: stem, leaf or the root of respectively discarded stem, leaf or root, Chinese photinia after stem, leaf or root discarded after capsicum results and eggplant fruit harvest being pruned to the stem that gets off or leaf and woaded blue clayed into power after drying, using ethanolic solution as extraction solvent again, lixiviate 1-7d, filter, filtrate adopts the method for reduced pressure concentration to obtain respectively medicinal extract, and then add conventional auxiliary material, according to common process, make plant acaricide of the present invention.
Described oven dry refers to: at 30-50 ℃, dry.
Described powder refers to: 20-40 object particulate powder.
Described ethanol refers to ethanolic solution or the absolute ethyl alcohol of 10%-95%v/v, and the 10-20 that its consumption is powder quality doubly.
Described reduced pressure concentration refers to: the crude extract obtaining after lixiviate is vacuumized to decompression to-0.1 atmospheric pressure and is placed in water-bath at 40-80 ℃, make crude extract simmer down to medicinal extract.
The present invention relates to the acaricidal application of above-mentioned plant resource, under stirring at normal temperature, water is added in plant acaricide, making it be diluted to plant extracts is that bulk drug accounts for after the concentration of 0.5-5wt% and sprays and use.
The present invention has the following advantages compared with the prior art:
(1) form synergy between the primary raw material of product of the present invention and can strengthen miticidal effect on the one hand, the pesticide resistance that can delay medicament due to the acting in conjunction of the active ingredient of the different mechanisms of action on the other hand produces.
(2) raw material be easy to get, process simple, low for equipment requirements, be extremely beneficial to suitability for industrialized production, and the solvent after reclaiming also can reuse.Four Plants raw material has plantation in the most of place of China, and after the stem of capsicum, Ye Hegen, eggplant fruit harvest discarded stem, leaf or root and Chinese photinia to prune the stem, the leaf that get off be all agricultural waste gurry, realized the recycling of resource, avoid secondary pollution, be conducive to agriculture sustainable development.
(3) this miticide derives from natural plant extracts, is easy under field conditions (factors) decompose, and to environment and ecosystem safety around, there is no problem of environmental pollution, is the biological miticide of a kind of pollution-free plant source.
