Description
Technical field
The present invention relates to garden tree pest Prevention Technique field, the ornamental plant of the root extract containing periploca spium is particularly related to
Insect pest liquid formulation for trunk injection and its application and preparation.
Background technology
Environment and development is the significant problem of global concern, preserves the ecological environment, realizes sustainable development, is directly connected to
Man's lot and future.At present, the greening work in city, the green areas of average per-person share are more and more paid attention in big and medium-sized cities and the small towns of urbanization
Area is significantly improved.Afforestation is while resident high-quality life space is brought, in order to prevent and treat on maintenance management
Disease, worm, crop smothering and the chemical pesticide applied also brings negative effect to urban environment.As long as afforestation area is bigger,
Pollution by pesticides is more serious；Afforested areas are then just more serious to directly affecting for resident closer to resident living place, pollution by pesticides.
At present, medicament implementation is carried out using Stem injection, trees pest and disease damage side is prevented and treated in the internal autonomous conduction principle of number wood by medicament
Method is simple and practical, safely and effectively, and it is environmentally friendly, start to attract people's attention.Meanwhile many scholars also begin to notice
The a large amount of of chemical agent use the resistance problems that the thing followed is insect, and therefore, how security implementation medicament does harm to solution
The worm resistance to the action of a drug is one of thorny problem that national governments face at present.
Periploca spium is one kind overgrowing property shrub of Asclepiadaceae Periploca, is that one kind is distributed widely in China Jilin, Liaoning, river
The plant of the northern areas such as north, Shanxi, serial cardiac glycosides material (seeing below formula 1,2,3) (Lee contained in its root extract
yan etc., 2012).
Such material mechanism of action is unique, mainly acts on the digestive system of insect, influences each in insect digestive system
Kind of digestive ferment activity (Lee yan etc., 2010；Patent publication No. -103130903/102675394), it is low toxicity, low-residual, right
Person poultry safety, the environment-friendly type natural plants source pesticide of non-environmental-pollution.Research shows, organic by methanol, ethanol or chloroform etc.
The periploca spium root extract that solvent extraction obtains respectively can be up to 82% to the anti-food rate and the death rate of diamondback moth and cabbage caterpillar larva
With more than 90% (Zhu Jiusheng etc., 2004)；He Ling etc. (2010) speculates that periploca spium insecticidal active ingredient can activate oriental armyworm and small
The trypsinlike enzyme of cutworm larva, and the trypsinlike enzyme of high activity may destroy the intestinal wall cell of test worm, sensitive test worm
Middle intestines are disintegrated, and intestinal contents are excessive, and it is dead to ultimately result in it.Lee yan etc. (2013) further study periploca spium active material
Pathological change to S.invicta Buren midgut tissue, as a result find boundary line mould between red fire ant intestinal wall and content after processing 24h
Paste, content distribution is at random, and middle intestines intestinal wall musculature starts shedding off；And the material can significantly inhibit intestines starch in red fire ant
The vigor of enzyme, reconfirm that intestines are one of action target of periploca spium active material in test worm, be a kind of digestion toxic agent.At present, thick stick
Willow root extract is mainly used in preventing and treating agricultural pests, also has auxiliary to be used for agricultural fertilizer (patent publication No. CN104311350/
104262027；) and medical science medicament (patent publication No. CN101502530) etc., but yet there are no it and be used for the tall and big trees in gardens
The preventing and treating of upper insect.
The content of the invention
, can the invention provides the ornamental plant insect pest liquid formulation for trunk injection and its application and preparation of a kind of root extract containing periploca spium
In a manner of being injected by gravity flow so that periploca spium insecticidal constituent imports plant parts, and it is low, harmful to solve preventive effect in the prior art
The worm resistance to the action of a drug, the injury technical problem such as natural enemy and non-target organism.
Technical scheme is as follows：
A kind of ornamental plant insect pest liquid formulation for trunk injection of the root extract containing periploca spium, including：Periploca spium root extract, first dimension
Salt, surfactant, antidecomposition agent and cosolvent, mass percent is followed successively by 4~20%, 0.75~1.5%, 1~10%,
0.35~0.5%, 10~20%, surplus is water.
The surfactant be Tween-80, AEO, diglycollic amide, one kind in organosilicon or
Several mixtures.
The cosolvent is the mixture of one or both of dimethyl sulfoxide, methanol, acetone.
Described antidecomposition agent is wgwinD902.
Each component is respectively by mass percentage：Periploca spium root extract 20%, emamectin benzoate 1.5%, surfactant
10%th, wgwinD902 0.35%, dimethyl sulfoxide 15%, surplus are water.
Described insect includes Semiptera, coleoptera, Homoptera, Diptera and lepidoptera pest.
A kind of preparation method of ornamental plant liquid formulation for trunk injection described in basis, step are as follows：Tieed up using cosolvent dissolving first
Salt, the first mixed liquor is obtained, periploca spium root extract and surfactant are then added in the first mixed liquor, is uniformly mixed
The second mixed liquor is obtained, the second mixed liquor is stirred and added in suitable quantity of water, produces a kind of gardens of root extract containing periploca spium
The dry preventing and treating liquor of insect pest of the plant note.
A kind of application of ornamental plant insect pest liquid formulation for trunk injection described in basis, it is green applied to preventing and treating city trees and shrubs, scenic spot
Change trees, shade tree, the insect in shelter belt, the insect includes Semiptera, coleoptera, Homoptera, Diptera and Lepidoptera
Insect.
In butt, from earth's surface 10-15cm obliquely 45 ° beat and reach the hole of xylem through 4mm, depth always, cut off
Injection bottle pipe front end, is whittled into inclined plane shape, with tip or needle-penetration medicine injecting device blind hole, the tree hole for then having accomplished fluently medicine-pouring pipe insertion
In, you can utilize gravity flow tree trunk injection；After treating that decoction imports completely, medicine bottle is pulled out, and with soil plug aperture.
Beneficial effects of the present invention：The injection drying agent preparation method is simple, with environment compatibility is good, good penetrability, dispenser letter
Just；Each class pest of ornamental trees and shrubs, such as the aphid of pierce-suck type and ceroplastes rubens can be effectively prevented and treated after being injected using gravity flow, is eaten into
The longicorn beetle of dryness and lucky fourth, phytophagous slug moth, and the non-target beneficial organism such as natural enemy is not killed；With medication is few, cost
It is low, preventive effect is high, operation the features such as not influenceed by the limitation and climate change of geographical conditions, especially suitable for preventing and treating arbor and city
The insect of city gardens, scenic spot landscape tree etc..
