Abstract
The invention relates to a preparation for preventing and controlling aphid and an application method. A preparation method comprises the following steps of: crushing pine needles dried in the shade and screening the crushed pine needles with a sieve of 60 meshes; extracting the pine needle powder or the pine needle pulp for 3 hours by using acetone; filtering the extract by using a sieve of 100 meshes to obtain filtrate, distilling the filtrate and reclaiming the acetone to obtain pasty pine needle extract; and preparing copper rosinate preparation stock solution by using the pasty pine needle extract, ethyl acetate, tween-80 and 0.5mol/L copper sulfate solution in a volume ratio of 1:2:3:3. During use, the stock solution is diluted with water by 300 to 500 times, and the diluted solution is sprayed on the surfaces of the plants harmed by the aphids. The method is simple and safe and has low production cost, the preventing and controlling effect is 85 percent, and the preparation is a new generation botanical pollution-free pesticide.
Description
Technical field
Patent of the present invention relates to a kind of anti-preparation eliminated 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 rosin soap, and insect is had to strong action of contace poison.Because of its adhesivity and permeability very strong, can corrode the insect body wall; Paraffin paper layer to scale insect has very strong corrosiveness.For preventing and treating multiple scale insect, aleyrodid, two spotted spider mite etc.Using method.By 20-25 times of liquid even spraying.The proportioning of raw material, rosin: caustic soda: water is 1:0.6-0.8:5-6.Water adds in pot, adds alkali, and heating is boiled, and alkali is dissolved.The rosin that will be ground into again fine powder evenly being sprinkled into slowly, boil altogether, stirs while boiling, and note supplementing with hot water, to maintain the original water yield.After about half an hour, rosin all dissolves, and becomes pitchy liquid, is rosin mixture stoste, and its proportion is 1.2g/cm
3left and right, rosin soap content is about 14%, containing free alkali approximately 10%.
The rosin acid sodium formulation is 30% rosin acid sodium emulsion, and meta-alkalescence be take and tagged as main, 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.Good film-forming property, the plate-out ability of this agent is strong, pollution-free, noresidue, to natural enemy, people and animals' basic security.Sometimes with other combined use of pesticides, probably affect its stability, cause drug effect to reduce.Therefore, should try one's best and use separately.
There are no being exclusively used in anti-pine needle extract preparation or the good copper rosinate preparation of rosin preparation, particularly control efficiency eliminated aphis.
The content of invention
The purpose of this invention is to provide a kind of pine needle (needle that comprises the 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-preparation eliminated 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, obtain pine needle meal or pine needle slurry;
B, get the pine needle meal of A, add acetone to submergence, standing lixiviate 3 hours; Or standing the pine needle slurry, lixiviate 3 hours; Through 100 orders, filter to get filtrate;
C, get the filtrate Distillation recovery acetone of B, obtain the paste extract from pine needles;
The copper-bath of D, the paste extract from pine needles of getting C, ethyl acetate, Tween-80,0.5mol/L, 1:2:3:3 is made into preparation stoste by volume.
A kind of application method of the anti-preparation eliminated aphis: get the above-mentioned a kind of anti-preparation stoste eliminated aphis, dilute with water 300-500 doubly, is sprayed onto and got final product by the surface of aphid damage plant.
Utilize method technique of the present invention simple, safety, production cost is low; A kind of anti-preparation eliminated aphis of producing, control efficiency, 85%, is the non-harmful biopesticide of plant resource of new generation.
Specific embodiment
Embodiment 1:
A, get and clean the pine needle 1000g dry in the shade, pulverized 60 orders, obtain the pine needle pine;

C, get the filtrate Distillation recovery acetone of B, obtain the paste extract from pine needles;
D, get the copper-bath of paste extract from pine needles, ethyl acetate, Tween-80,0.5mol/L, 1:2:3:3 is made into preparation stoste by volume.
A kind of application method of the anti-preparation eliminated aphis: get the above-mentioned a kind of anti-preparation stoste eliminated aphis, 500 times of dilute with waters, be sprayed onto the surface that is subject to the aphid damage plant, and within 24 hours, control efficiency is 85%.
Embodiment 2:
A, get and clean fresh pine needle 1000g, chopping, defibrination, cross 60 orders with the acetone pulp washing, obtains pine needle and starch;
B, the pine needle slurry of getting A are standing, lixiviate 3 hours, through 100 orders, filter to get filtrate;
C, get the filtrate Distillation recovery acetone of B, obtain the paste extract from pine needles;
D, get the paste extract from pine needles of C, 1:2 adds the sodium hydroxide solution of 0.1mol/L by volume, is made into a kind of anti-preparation stoste eliminated aphis.
A kind of application method of the anti-preparation eliminated aphis: get the above-mentioned a kind of anti-preparation stoste eliminated aphis, 300 times of dilute with waters, be sprayed onto the surface that is subject to the aphid damage plant, and within 24 hours, control efficiency is 85%.
