Description
Technical field
The present invention relates to garden tree pest Prevention Technique field, refer to the ornamental plant insect pest liquid formulation for trunk injection containing periploca spium root extract and Application and preparation thereof especially.
Background technology
Environment and development is the significant problem of global concern, preserves the ecological environment, realizes sustainable development, is directly connected to and man'ss lot and future.At present, the greening work in city is more and more paid attention in the small towns of big and medium-sized cities and urbanization, and per capita green area is significantly improved.Afforestation while bringing resident's high-quality life space, on maintenance management in order to anti-cure the disease, worm, crop smothering and the chemical pesticide used also brings negative effect to urban environment.As long as afforestation area is larger, pesticide pollution is more serious; Afforested areas is more close to resident living place, and pesticide pollution is then just serious on the direct impact of resident.At present, use Stem injection to carry out medicament enforcement, rely on the autonomous conduction principle control trees damage by disease and insect method simple practical of medicament in several wooden body, safe and effective, and environmentally friendly, start the attention causing people.Meanwhile, many scholars also start to notice that a large amount of use thing followeds of chemical agent are the resistance problems of insect, therefore, and how security implementation medicament and to solve pest resistance to insecticide be one of thorny problem of facing at present of national governments.
Bar willow is ricinus communis section bar willow, a tendril naturally shrubs of the genus is a widely distributed in north China's jilin, liaoning, hebei, shanxi and other areas of plant, its root extract contains a series of cardiac glycosides material (see below 1, 2, 3) (lee Gong etc., 2012).
The physical mechanism is unique, mainly ACTS on the pests of the digestive system, the activity of digestive enzymes that affect the pests in the digestive system (li gong, etc., 2010; patent publicly - 103130903/102675394), is a low toxicity, low residue, safe, no pollution of the environment for human natural botanical pesticides.Research shows, the periploca spium root extract obtained by the organic solvent extraction such as methyl alcohol, ethanol or chloroform can reach more than 82% and 90% (Zhu Jiusheng etc., 2004) respectively to the anti-food rate of diamond-back moth and cabbage caterpillar larva and lethality; He Ling etc. (2010) infer that periploca spium insecticidal active ingredient can activate the trypsinlike enzyme of oriental armyworm and black cutworm larvae, and highly active trypsinlike enzyme may destroy the intestines parietal cell of examination worm, in responsive examination worm, intestines are disintegrated, and intestinal contents is excessive, and finally cause it dead.LiGong et al. (2013) further studied the poles of active substances for the invasion of red imported fire ants in intestinal tissue pathological changes, it is found that deal with 24 h after fire ants intestinal wall with blurred between content, content distribution of scattered, irritable bowel wall in muscle tissue begin to fall off;And the material can significantly inhibit intestinal of amylase activity in the red imported fire ants, try again confirmed the role of bowel for poles of active material in the insect one of targets, is a kind of digestive poison.At present, periploca spium root extract is mainly used in preventing and treating pest, also assists for agricultural fertilizer (patent publication No. CN104311350/104262027; ) and medical science medicament (patent publication No. CN101502530) etc., but yet there are no the control of its insect on the tall and big trees in gardens.
Summary of the invention
The invention provides a kind of ornamental plant insect pest liquid formulation for trunk injection containing periploca spium root extract and Application and preparation thereof, the mode can injected by self-flowing type, make periploca spium insecticidal constituent import plant parts, solve the technical problems such as preventive effect in prior art is low, pest resistance to insecticide, injury natural enemy and non-target organism.
Technical scheme of the present invention is as follows:
A kind of ornamental plant insect pest liquid formulation for trunk injection containing periploca spium root extract, comprise: periploca spium root extract, emamectin benzoate, surfactant, anti-distintegrant and cosolvent, mass percent is followed successively by 4 ~ 20%, 0.75 ~ 1.5%, 1 ~ 10%, 0.35 ~ 0.5%, 10 ~ 20%, and surplus is water.
Described surfactant is the mixture of one or more in Tween-80, fatty alcohol-polyoxyethylene ether, diglycollic amide, organosilicon.
Described cosolvent is one or both the mixture in methyl-sulfoxide, methyl alcohol, acetone.
Described anti-distintegrant is wgwinD902.
Each component is respectively by mass percentage: periploca spium root extract 20%, emamectin benzoate 1.5%, surfactant 10%, wgwinD902 be 0.35%, methyl-sulfoxide 15%, surplus is water.
Described insect comprises Semiptera, coleoptera, Homoptera, diptera and lepidoptera pest.
The preparation method of the ornamental plant liquid formulation for trunk injection described in a kind of basis, step is as follows: use cosolvent to dissolve emamectin benzoate, obtain the first mixed liquor, then in the first mixed liquor, periploca spium root extract and surfactant is added, be uniformly mixed to obtain the second mixed liquor, being stirred by second mixed liquor adds in suitable quantity of water, obtains the dry control liquor of a kind of ornamental plant insect pest containing periploca spium root extract note.
An application for ornamental plant insect pest liquid formulation for trunk injection described in basis, be applied to the insect in control city trees and shrubs, scenic area landscape tree, street tree, shelter belt, described insect comprises Semiptera, coleoptera, Homoptera, diptera and lepidoptera pest.
At butt, from 10-15cm place, earth's surface obliquely 45 ° beat the hole always reaching xylem through 4mm, the degree of depth, cut off injection bottle pipe front end, be whittled into inclined plane shape, by most advanced and sophisticated or needle-penetration medicine injector blind hole, then medicine-pouring pipe is inserted in the tree hole accomplished fluently, self-flowing type tree trunk injection can be utilized; After treating that liquid imports completely, pull out medicine bottle, and use soil plug aperture.
Beneficial effect of the present invention: this injection drying agent preparation method is simple, good with environment compatibility, good penetrability, dispenser are easy; Adopt self-flowing type inject after effectively can prevent and treat each class pest of ornamental trees and shrubs, the aphid of such as pierce-suck type and ceroplastes rubens, the longicorn beetle of moth dryness and lucky fourth, phytophagous slug moth, and the not non-target mark beneficial organism such as killed natural enemies; Have that medication is few, cost is low, preventive effect is high, operation by the feature such as the restriction of geographical conditions and the impact of climatic variation, be specially adapted to the insect preventing and treating arbor and city trees and shrubs, scenic area landscape tree etc.
