Abstract
The invention provides a tree trunk injection liquid containing emamectin benzoate and thiacloprid, and a preparation method thereof. The tree trunk injection liquid comprises, by mass, 2-10% of emamectin benzoate, 2-10% of thiacloprid, 3-15% of a surfactant, 2-6% of glacial acetic acid and 59-90% of an alcoholic solvent. The trunk injection liquid has the characteristics of small dosage, low cost, high control effect, only taking effect on target pests of trees, no damage to natural enemy insects, environmental protection, wide application range, simple and convenient operation, and high work efficiency, is unlimited by geographical conditions and climate change, can be applied in an anhydrous non-contact manner, is safe to human and environment, and can pertinently control pests in forests, urban landscapes, scenic area greening trees, street trees, shelter belts and fruit trees.
Description
Technical field
The present invention relates to trees control of insect technical field, refer to especially a kind of trunk injection liquor containing first dimension salt and thiacloprid and preparation method thereof.
Background technology
By note dry method, carry out dispenser, rely on the autonomous conduction of medicament in several wooden bodies with control trees damage by disease and insect method as far back as nineteen twenty-six the U.S. carried out practical application and developed tree chemical injection machinery.As a kind of using method of agricultural chemicals, due to its have that formulation rate is few, preventive effect is high, environmentally friendly, to the people, animal feature such as safely, be subject to people's attention always.Trees damage by disease and insect, particularly borer pest and limb venereal disease evil is atomic by conventional application method control efficiency, the generation of uncontrollable this class damage by disease and insect and spreading.
In recent years, trees damage by disease and insect is on the rise, and particularly borer pest is as longicorn, moth-eaten moth, a few Tintinnid.The generation of Monochamus alternatus, when itself causing pine tree harm, also causes a large amount of propagation of pine wood nematode, and southern pine forest is caused to destructive strike especially.The harm of urban green-making tree longicorn is also on the rise, and is endangered trees to be easily blown over by the wind, and causes security incident.Trunk cadre insect adopts conventional spray pesticide method cannot prevent and treat it, so research and the application of the dispenser of note dry method are just seemed to very urgent.At present, on producing, the dry pesticide application technology of applied note has a variety ofly, according to its injection mode difference, can be divided into malicious label method, stem brush bandaging strapping, high pressure medicine-injecting method and gravity medicine-injecting method.Because these dispenser methods all exist different shortcomings, seriously restrict the application of spread.
Summary of the invention
The present invention proposes a kind of trunk injection liquor containing first dimension salt and thiacloprid and preparation method thereof, has solved that in prior art, medication is many, preventive effect is low, technical problem that cannot target removal pest.
Technical scheme of the present invention is achieved in that
Containing a trunk injection liquor for first dimension salt and thiacloprid, its component comprises: first dimension salt, thiacloprid, surfactant, glacial acetic acid and alcohols solvent; Its mass percent is: 2-10%, 2-10%, 3-15%, 2-6%, 59-90%.
As preferred technical scheme, described first dimension salt, thiacloprid, surfactant, glacial acetic acid and alcohols solvent; Its mass percent is: 2-5%, 2-5%, 6-10%, 3-5%, 75-87%.
As preferred technical scheme, described surfactant is fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, polyoxyethylene nonylphenol ether, one or both mixtures of diglycollic amide.
As preferred technical scheme, described surfactant is the mixture of fatty alcohol-polyoxyethylene ether and polyoxyethylene nonylphenol ether.
As preferred technical scheme, described alcohols solvent is one or both mixture of methyl alcohol, ethanol, isopropyl alcohol, n-butanol, diethylene glycol butyl ether.
A preparation method who ties up the trunk injection liquor of salt and thiacloprid containing first, comprising:
Use glacial acetic acid to dissolve thiacloprid, obtain the first mixed liquor;
Use alcohols solvent to dissolve first dimension salt, obtain the second mixed liquor;
Mix described the first mixed liquor and the second mixed liquor, add afterwards surfactant, be uniformly mixed, obtain the trunk injection liquor containing first dimension salt and thiacloprid.
A kind of trunk injection liquor containing first dimension salt and thiacloprid of the present invention, adopts the various insects that can effectively prevent and treat trees after note dry application medicine, as the cause harm insect of mode of the multiple differences such as aphid, ceroplastes rubens, longicorn, pine wood nematode, bark beetle moth, two spotted spider mite.Medicament of the same race is as adopted traditional spray method dispenser control, and using dosage is identical, and to moth dryness insect, the control efficiency of leaf mining insect is poor.When control pierce-suck type and To Leaf-feeding Insects, in the situation that strengthening spray amount and concentration, can reach certain control efficiency, also bring the harm of the beneficial organisms such as killed natural enemies of environmental pollution simultaneously thereupon, while particularly preventing and treating arbor and city trees and shrubs, scenic area landscape tree, endanger more obviously, not only cause medicament waste, contaminated environment also may cause poisoning simultaneously.
Liquid formulation for trunk injection of the present invention, have that medication is few, cost is low, preventive effect high, only the target pest of trees is worked, do not injure natural enemy insect, environmentally friendly, applied widely, simple to operation, work efficiency is high, is not subject to the restriction of geographical conditions and the impact of climatic variation, the dispenser of anhydrous contactless property, to human and environment safety, the insect on forest, city trees and shrubs, scenic area landscape tree, street tree, shelter belt and fruit tree is carried out to specific aim control.
