Description
Technical Field
The invention relates to an injection for pine trees, and belongs to the technical field of pesticides.
Background
Pine wood nematodes are a particularly dangerous quarantine pest that harm pine trees. In pine trees infested by pine wood nematodes, the vascular bundle system quickly loses its water transport function and causes wilting or even death. The natural spread of bursaphelenchus xylophilus is mainly transmitted by means of the vector insect monochamus alternatus. The prevention and control measures for the pine wood nematode are various, and chemical prevention and control is an important means for rapidness and effectiveness. Chemical control includes two: firstly, the prevention and cure to the vector insect monochamus alternatus hope is realized through the mode that the aircraft sprays the insecticide in many ways. Secondly, the trunk medicine injection technology. The trunk pesticide injection technology for preventing and treating the pine wood nematodes has the advantages of precise pesticide application, no target organism and environmental friendliness, and becomes an important means for forestry technicians. The trunk medicine injection technology can be divided into two types according to the medicine liquid input mode: pressurized and gravity flow. The pressurized injection means that the liquid medicine enters and is stored in the xylem of the forest rapidly under the action of external force and then is transmitted to each part of the tree body along with transpiration flow. The gravity injection is invented according to the fluid mechanics and transpiration principle in trees. When the pesticide is injected, the pesticide injector filled with pesticide liquid is opened, the pesticide liquid is inserted into the small hole drilled on the trunk after the needle point pierces the vent hole, the pesticide liquid and the transpiration liquid flow in the tree maintain a certain pressure difference, and the pesticide liquid flows into the tree body under the action of the pressure difference and is distributed on each part of the tree body along with the transpiration liquid flow of the tree, so that the purpose of preventing and treating the plant diseases and insect pests of the tree is achieved. The gravity flow injection is a general use method in the market due to convenient use and low requirement on equipment. However, problems such as too slow flow rate of the liquid medicine and crystallization of the liquid medicine during the injection drying process have been found in the use process. The slow flow rate of the liquid medicine leads to the fact that the effective components can not enter the tree body more quickly, and the effect of the liquid medicine can not be exerted better. The liquid medicine is crystallized and separated out, resulting in the waste of effective components. Meanwhile, the existing pesticide injection generally adopts a solvent with high toxicity, which is not beneficial to health.
Disclosure of Invention
The invention aims to provide an injection for pine trees, aiming at the defects of easy crystallization and high toxicity of liquid medicine in the prior art and improving the drug effect.
The invention solves the technical problem by the following technical scheme: an injection for pine trees comprises the following components in percentage by mass: 0.1-10% of abamectin or emamectin benzoate, 5-25% of wetting penetrant, 10-50% of crystallization inhibitor and the balance of solvent.
The wetting penetrating agent is at least one of fatty alcohol polyoxyethylene ether, fatty alcohol block polyether, alkylphenol polyoxyethylene ether, castor oil polyoxyethylene ether and sodium diisooctyl sulfosuccinate.
The crystallization inhibitor is diethylene glycol, triethylene glycol, tetraethylene glycol, dipropylene glycol or tripropylene glycol.
The crystallization inhibitor is diethylene glycol.
The content of the crystallization inhibitor is 20-40%.
The solvent is dimethylformamide, dimethylacetamide, nitrogen methyl pyrrolidone, dimethyl sulfoxide and cyclohexanone.
The dosage form is soluble solution.
When in use, the components are prepared according to the proportion and then are filled in a special injection bottle for trunk injection.
The invention finds that the diethylene glycol has the functions of inhibiting crystallization and promoting absorption and conduction, and the formula can effectively solve the problems of slow flow rate and crystallization precipitation of liquid medicine through continuous search. Compared with the prior art, the invention has more reasonable compatibility and composition and has the beneficial effects that: solves the problem of too low speed of the liquid medicine entering the tree body in the application process, so that the liquid medicine can enter the tree body at a higher speed and quickly take effect on the pine wood nematode in the tree body. Solves the problems of liquid medicine precipitation and crystallization in the application process. The waste of the medicine in the using process is avoided.

From the data results in table 4, it can be found that the addition of the crystallization inhibitor significantly inhibits the crystallization of the drug solution during the injection drying process, as compared with example 28; compared with the example 29, the addition of the wetting penetrant obviously improves the liquid absorption speed of the liquid medicine in the injection drying process. Compared with examples 30 and 31 containing diethylene glycol butyl ether, diethylene glycol in example 1 containing diethylene glycol can well inhibit the crystallization phenomenon during the injection drying process of the liquid medicine. Example 1 compared with example 3/4/5/6, the liquid medicine of example 1 was absorbed quickly within 2 hours, and the liquid medicine of example 3/4/5/6 was absorbed within 3 hours, indicating that the liquid medicine was absorbed quickly during the injection drying process when the wetting penetrant was fatty alcohol-polyoxyethylene ether.
From the data results in table 5, it can be found that, except for example 15 (containing 0.1% of abamectin) and example 16 (containing 1% of abamectin) in which the abamectin content is low, other examples have a good effect of preventing the pine wood nematodes.
In conclusion, when the crystallization inhibitor is diethylene glycol, the crystallization phenomenon of the liquid medicine in the injection drying process can be effectively inhibited, and the optimal effect is achieved when the content is preferably 20-30%. The addition of the wetting penetrating agent can effectively improve the absorption speed of the liquid medicine, and when the wetting penetrating agent is fatty alcohol-polyoxyethylene ether, the liquid medicine can be absorbed by the trunk within 2 hours, so that the absorption effect is good. The embodiment 1 can effectively inhibit the crystallization phenomenon in the trunk injecting process of the liquid medicine, can be quickly absorbed by the trunk, has good control effect on the pine wood nematode, and is a good injection for the pine wood nematode.
The invention has been described with reference to specific examples, and it will be understood by those skilled in the art that various changes in the materials, process conditions, and combinations or proportions of the active ingredients and other elements may be made without departing from the scope of the invention.
