Description
Technical field
That the present invention relates to is a kind of preparation method of technical field of pesticide, specifically is a kind of control Tetranychus cinnabarinus preparation and preparation and application based on albizzia julibrissin extract.
Background technology
Tetranychus cinnabarinus (Tetranychus cinnabarinus) is a kind of important phytophagy tetranychid.This mite individuality is little, the breeding fast, population density is big, harm is serious, is a kind of important economic evil mite, and its host plant is kind more than 100 nearly, and diversified economy crop and ornamental plants and weeds such as cotton, various vegetables, melon, beans, willow, Chinese rose, jujube are arranged.Tetranychus cinnabarinus mainly in the harm of the plant leaf blade back side, is weaved silk and is knotted.The blade of being injured manifests the floral white fleck at first, along with the increase spot of the extent of injury increases gradually.Intermediary and later stages seriously are injured, and cause plant short and small, even cause fallen leaves, fallen flowers.For many years, control to the mite class mainly relies on chemical pesticide, but the frequent a large amount of chemical pesticides that use can produce the ferocious again problem such as stick up of resistance, residual and harmful mite inevitably, therefore, the miticide of seeking highly effective and safe is imperative, and greatly developing the plant resource miticide is a developing direction of current pesticide industry, and the requirement that the plant resource miticide meets the agricultural sustainable development of 21 century has wide application development prospect.Believe that in the near future the plant resource miticide will be made bigger contribution for safeguarding environmental health and human security.
Albizzia (Albizzia julibrissin Durazz) plant is a pulse family Mimosoideae plant, and about 100 kinds of the whole world is distributed widely in all over the world.China has 16 kinds, and major part originates in the south and the west and south, has found that at present it has the Xie Yu of calming the nerves, the effect of activating blood circulation and reducing swelling, and multiple fungi all had inhibitory action.
Through the prior art literature search is found, Yang Xiujuan etc. are at " Fujian agriculture journal " (the 19th volume, the 2nd phase) is entitled as in the article of " plant extraction liquid is to the inhibitory or killing effect of Meloidogyne incognita " and reported that albizzia julibrissin extract has certain inhibitory or killing effect to Meloidogyne incognita, this extract is to be raw material with the silk tree leaf, after will pulverizing 20 mesh sieves, take by weighing quantitative silk tree powder and be dissolved in (plant powder and water weight ratio are 1: 20) in the quantitative sterile water, vibration is soaked and is extracted the extract that obtained in 24 hours; In retrieving further again, do not find that albizzia julibrissin extract is used to prevent and treat the research report of Tetranychus cinnabarinus.
Summary of the invention
The present invention is directed to the prior art above shortcomings, a kind of control Tetranychus cinnabarinus preparation and preparation and application based on albizzia julibrissin extract is provided, have effective noresidue, kill characteristics such as the mite scope is wide, production cost is low, economical and practical, environmentally friendly.
The present invention is achieved by the following technical solutions:
The present invention relates to a kind of control Tetranychus cinnabarinus preparation based on albizzia julibrissin extract, its component and weight percent are: silktree albizia bark extract 10～40%, silk tree stem extraction 10～40%, silk tree leaf extract 5～35%, Flos Albiziae extract 5～35% and distilled water 20～60%.
The present invention relates to the preparation method of above-mentioned control Tetranychus cinnabarinus preparation based on albizzia julibrissin extract, by respectively skin, stem, leaf, the flower of silk tree being clayed into power after drying, adopt the method for concentrating under reduced pressure to obtain medicinal extract respectively with ethanol as extraction solvent again, medicinal extract is scattered in the distilled water makes miticide at last by above-mentioned prescription.
The temperature of described oven dry is 10-50 ℃;
The granularity of described powder is the 10-60 order;
Described ethanol is meant: the ethanolic solution of 25%-70%v/v or absolute ethyl alcohol, its consumption are 10-20 times of powder quality.
Described concentrating under reduced pressure is meant: the crude extract that obtains after the lixiviate is vacuumized reduce pressure-0.1 atmospheric pressure and place 40-80 ℃ of following water-bath, make crude extract simmer down to medicinal extract.
Described dispersion is meant: adopt the mode of ultrasonic dispersion that medicinal extract is scattered in the distilled water.
The present invention relates to the application method of above-mentioned control Tetranychus cinnabarinus preparation based on albizzia julibrissin extract, by under 30-50 ℃ the stirring environment water added wherein and be diluted to the concentration of 1-3wt% after be cooled to normal temperature, form aqua and spray and be applied on the crops.
The present invention has following advantage compared with the prior art:
(1) synergy can strengthen miticidal 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.
(2) raw material is easy to get, processes solvent simple, low for equipment requirements, after reclaiming and also can reuse.
(3) this miticide derives from the natural traditional Chinese medicine plant extracts, and utilizes its water-soluble characteristics, and it is made into aqua, so its environmentally safe to people, animal safety, is the biological miticide of a kind of pollution-free plant source.
