Abstract
The invention discloses a kind of plant source aphicide for lettuce, it is made up of following raw material：20 30 parts of orange peel, 10 30 parts of gold argy wormwood, 10 30 parts of pale reddish brown mother chrysanthemum, 15 25 parts of tripterygium wilfordii, 15 25 parts of black false hellebore, 15 25 parts of Golden Larch Bark, 58 parts of synergist.Plant source aphicide of the present invention has nontoxic, low-residual, pollution-free, extensive without the resistance to the action of a drug, high selectivity, raw material sources, can kill the pest and disease damages such as aphid, and the method for the present invention has the advantages of technique is simple, cost is low.
Description
Technical field
The present invention relates to technical field of pesticide, and in particular to a kind of for the plant source aphicide of lettuce and its preparation side
Method.
Background technology
Lettuce, composite family, Lactuca, one, biennial herb plant.Lettuce can be divided into leaf and use and two classes of stem.The name of lettuce
Claim a lot, to be referred to as " garden lettuce " in herbal medicine, " lettuce " and " stone lettuce ".Leaf lettuce is also known as spring vegetable, romaine lettuce, and lettuce sativa is again
Claim asparagus lettuce, fragrant bamboo shoot.China various regions cultivated area asparagus lettuce is more than romaine lettuce.The meat of asparagus lettuce is tender, and stem can be eaten raw, be cold and dressed with sauce, stir-frying and eating, be drying
Or pickling.Romaine lettuce mainly eats blade or leaf-head, has been sent out in recent years in the big city of the especially southern coastal provinces in each big city
Exhibition, turn into the staple vegetable of current increase pattern variety.But will influence its quality after lettuce insect infestation, mainly with
Adult aphid, larvae aphid are clustered in lobus cardiacus, blade back thorn draws food, cause leaf malformation to distort.
Botanical pesticide is the agricultural chemicals using plant resource explorationses, is a kind of some portions of plant for utilizing and having insecticidal activity
Insecticide made of its active ingredient is extracted in position.Due to nature the various chemical compositions in plant have been formd it is perfect
Degradation mechanism, botanical pesticide easily decomposes, and residual quantity is low, safer to people and animals, environment, and medicine is not also produced to crop
Evil, the crop being consumed directly by humans especially suitable for veterinary antibiotics and tealeaves etc., thus botanical pesticide is also referred to as green agriculture
Medicine.Therefore, environmental protection is met, health, the efficient, less toxic of sustainable development theory, low-residual, the botanical pesticide that is compatible with the environment are opened
Hair just turns into the theme of current pesticide research.
The content of the invention
For above-mentioned, it is an object of the invention to provide a kind of plant source aphicide for lettuce and preparation method thereof.
The present invention adopts the technical scheme that：
A kind of plant source aphicide for lettuce, it is made up of following raw material：Orange peel 20-30 parts, gold argy wormwood
10-30 parts, pale reddish brown mother chrysanthemum 10-30 parts, tripterygium wilfordii 15-25 parts, black false hellebore 15-25 parts, Golden Larch Bark 15-25 parts, synergist 5-8 parts.

Preferably, described synergist is urea.
The preparation method of the plant source aphicide, comprises the following steps：（1）Each component raw material is weighed according to proportioning,
Pulverization process is carried out after mixing, obtains mixed powder；（2）Mixed powder is soaked with organic solvent and extracted, extraction time is 28 hours, leaching
Temperature raising degree is 75 DEG C, filters, is concentrated to give extract medicinal extract, then extract medicinal extract is diluted with distilled water into concentration 0.5-1g/mL
Extract solution；（3）Urea is added, stirs and obtains plant source aphicide.
Described organic solvent is the ethanol solution or ethyl acetate solution that mass fraction is 70-80%.
It is an advantage of the invention that：Plant source aphicide of the present invention have nontoxic, low-residual, it is pollution-free, without the resistance to the action of a drug, height
Selectivity, raw material sources are extensive, can kill the pest and disease damages such as aphid, and that the method for the present invention has that technique is simple, cost is low is excellent
Point.
