Abstract
The invention relates to a pine needle extract preparation for controlling aphids and an application method thereof. A preparation method of the pine needle extract preparation comprises the steps of: A, smashing pine needles dried in shadow and screening through a 60-mesh sieve, or grinding fresh pine needles into thick liquid and screening the thick liquid through a 60-mesh sieve; B, lixiviating the pine needle powder or pine needle thick liquid in the step A with acetone for 3 hours; C, filtering extractives obtained in the step B through a 100-mesh sieve to obtain filtrate, and distilling the filtrate for recovering the acetone to obtain a cream pine needle extract; and D, adding the cream pine needle extract into a 0.1mol/L sodium hydroxide solution according to a volume ratio of 1:2 to prepare a basic solution of the pine needle extract preparation for controlling the aphids; and when in use, diluting the basic solution with 300-500 times of water, and spraying the diluted solution to the surfaces of plants damaged by the aphids. The preparation method is simple and safe and has low production cost, and the pine needle extract preparation has a controlling effect of 85% and belongs to new-generation plant-sourced nuisanceless bio-pesticides.
Description
Technical field
Patent of the present invention relates to a kind of anti-extract from pine needles preparation that eliminates aphis, and belongs to the botanical pesticide manufacture field.
Background technology
Rosin mixture is the pitchy liquid of being made by rosin and caustic soda or soda ash, and main component is a rosin soap, and insect is had strong action of contace poison.Because of its adhesivity and permeability are very strong, can corrode the insect body wall; Paraffin paper layer to scale insect has very strong corrosiveness.Be used to prevent and treat multiple scale insect, aleyrodid, two spotted spider mite etc.Using method.With 20-25 times of liquid even spraying.Proportion of raw materials, rosin: caustic soda: water is 1: 0.6-0.8: 5-6.Water adds in the pot, adds alkali, and heating is boiled, and alkali is dissolved.The rosin that will grind into fine powder evenly being sprinkled into slowly, boil altogether, stir while boiling, and note replenishing, to keep the original water yield with hot water.After half an hour, the rosin off-bottom becomes pitchy liquid, is rosin mixture stoste approximately, and its proportion is about 1.2g/cm3, and rosin soap content is about 14%, contains free alkali about 10%.
The rosin acid sodium formulation is 30% rosin acid sodium emulsion, and meta-alkalescence to tag, can also corrode the polypide epidermis, sticks together, wraps up insect, makes its death.Be diluted to 300～500 times of liquid and use, can effectively prevent and treat vegetable aphid, aleyrodid, two spotted spider mite etc.Strong, pollution-free, the noresidue of good film-forming property, the plate-out ability of this agent is to natural enemy, people and animals' basic security.Sometimes with other combined use of pesticides, influence its stability probably, cause drug effect to reduce.Therefore, should try one's best and use separately.
Do not see to have and be exclusively used in the anti-pine needle that eliminates aphis and carry thing preparation or rosin preparation.
The content of invention
The purpose of this invention is to provide a kind of pine needle (needle that comprises pine trees such as masson pine, black pine) extract that utilizes, make biological killing aphids preparation, require method easy, practical, cost is low effective.
A kind of anti-extract from pine needles preparation that eliminates aphis, compound method is:
A, get and clean the pine needle that dries in the shade, pulverized 60 orders, or get fresh pine needle, defibrination, acetone pulp washing and cross 60 orders, pine needle meal or pine needle slurry;
B, at the pine needle meal of A, add acetone to submergence, left standstill lixiviate 3 hours; Or pine needle slurry left standstill lixiviate 3 hours; Filter to get filtrate through 100 orders;
C, acetone is reclaimed in the distillation of the filtrate of B, the paste extract from pine needles;
D, get the paste extract from pine needles of C, added the sodium hydroxide solution of 0.1mol/L in 1: 2 by volume, be made into a kind of anti-extract from pine needles preparation stoste that eliminates aphis.
A kind of application method of the anti-extract from pine needles preparation that eliminates aphis: get the above-mentioned a kind of anti-extract from pine needles preparation stoste that eliminates aphis, dilute with water 300-500 doubly is sprayed onto and got final product by the surface of aphid damage plant.
Utilize method technology of the present invention simple, safety, production cost is low; A kind of anti-extract from pine needles preparation of being produced that eliminates aphis, control efficiency are the non-harmful biopesticides of plant resource of a new generation 85%.
