Description
Technical field
The present invention relates to a kind of technical field of pesticide, specifically, is a kind of biological insecticides its preparation method for romaine lettuce
Background technology
Insect pest mainly Tetranychus urticae and the aphid that romaine lettuce is main, the main clustering of Tetranychus urticae is at the vacuum side of blade of host, minority draws juice face of blade, rear blade of being injured presents canescence or the tiny chlorosis spot of withered yellow, and then blade is burnt cigarette shape, time serious, blade is withered comes off, and even causes plant dead.When insect density is very large, a large amount of polypide is gathered in the top of blade and the tip, and assemble worm ball rose pink one by one, large person is as peanut grain.Now plant is often closely withered dead.Because the pesticide resistance of Tetranychus urticae is high, therefore should prevent and treat in early days in generation, be improve control efficiency, can mix synergist or wash the interaction platform clothing powder etc. of village official in liquid, and adopt drip washing formula to spray medicine.Mainly adopt chemical pesticide to the control of insect pest at present, harmful, adopt biological insecticides tool to be of great significance, the research at present for the biological insecticides of romaine lettuce have not been reported.
Summary of the invention
For present situation, the technical problem that the present invention mainly solves be to provide a kind of can the biological insecticides of effectively preventing romaine lettuce Tetranychus urticae and aphid, for solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
For biological insecticides for romaine lettuce, be made up of following component and weight percent content: Ginger P.E 8 ~ 13%, garlic P.E 10 ~ 15%, tree-of-heaven bark extract 5 ~ 12%, Semen Armeniacae Amarum extract 12 ~ 15%, Fructus Gleditsiae Abnormalis extract 6 ~ 15%, Fructus Piperis extract 8 ~ 20%, nimbin extract 4 ~ 10%, barberry extract 10 ~ 20%.
Described insecticide is for the Tetranychus urticae of romaine lettuce and aphid.
The above-mentioned process for preparing bio-insecticide for romaine lettuce, its concrete preparation process is:
(1) preparation of ginger and garlic P.E: choose fresh garlic or ginger, clean, dry after take 500g, be put in the ethanol of volumetric concentration 75% and carry out surface sterilization 5min, be placed in tissue refiner 3 times with aseptic water washing, add 200mL sterile water, pasty state is made into the rotating speed homogenate 8min of 5000r/min, centrifugal 10min under the condition of then temperature 4 DEG C, rotating speed 10000r/min in centrifuges, get supernatant after 0.25 μm of bacteria filters filters, namely obtain garlic or Ginger P.E, be placed in 4 DEG C of refrigerators and save backup;
(2) various extract is prepared: tree-of-heaven skin, semen armeniacae amarae, Chinese honey locust, white pepper, nimbin, barberry are clayed into power after drying respectively, again using organic solution as extraction solvent, lixiviate, filter, obtain tree-of-heaven bark extract, Semen Armeniacae Amarum extract, Fructus Gleditsiae Abnormalis extract, Fructus Piperis extract, nimbin extract, barberry extract respectively;
(3) adopt the method for reduced pressure concentration to obtain medicinal extract respectively the various extracts obtained in above-mentioned steps, and then add customary adjuvant, conveniently technique, makes vegetable insecticide.
The preparation of above-mentioned tree-of-heaven bark extract, its concrete steps are: dried by the baking oven that tree-of-heaven bark is placed in 45 DEG C, 60 mesh sieves were pulverized with herb roller, collect flour, then by flour, adopt soxhlet extraction, in extracting bottle, add 250ml ether, utilize the water temperature of 40 DEG C to carry out heating water bath extracting, obtain tree-of-heaven bark extract.
Described reduced pressure concentration refers to: vacuumized by the crude extract obtained after lixiviate and reduce pressure to negative 1 atmospheric pressure and water-bath at being placed in 60 DEG C, make crude extract simmer down to medicinal extract.
The application of above-mentioned romaine lettuce biological insecticides, by it at the temperature of 40-45 DEG C, adds water, is cooled to normal temperature after being diluted to the concentration of 1-3wt%, forms aqua and sprays.
The invention has the beneficial effects as follows:
(1) the present invention be directed to the formula that romaine lettuce is developed specially, to romaine lettuce Tetranychus urticae and aphid, there is special efficacy, can these two kinds of diseases of effectively preventing to the harm of romaine lettuce, thus improve the quality and yield of romaine lettuce.
(2) the invention provides that a kind of efficient, noresidue, production cost are low, economical and practical, the romaine lettuce biological insecticides of environmental friendliness, high comprehensive performance, reduce chemical pesticide to the harm of human body.
(3) forming the primary raw material of product of the present invention is a kind of multicomponent mixture, can strengthen insecticidal effect on the one hand, and the pesticide resistance that can delay medicament due to the acting in conjunction of the active ingredient of the different mechanism of action on the other hand produces.
(4) this insecticide derives from natural plant extracts, is easy under field conditions (factors) decompose, and to the ecology erroneous zone of environment and surrounding, not having problem of environmental pollution, is a kind of insecticide without environmental pollution.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
For biological insecticides for romaine lettuce, be made up of following component and weight percent content: ginger 13%, garlic P.E 10%, tree-of-heaven bark extract 10%, Semen Armeniacae Amarum extract 15%, Fructus Gleditsiae Abnormalis extract 10%, Fructus Piperis extract 17%, nimbin extract 10%, barberry extract 15%.
The above-mentioned process for preparing bio-insecticide for romaine lettuce, its concrete preparation process is:
