Background
Bursaphelenchus xylophilus is a devastating disease of pine trees, known as cancer of pine trees. Once the pine tree is infected with the disease, the pine tree can die in about 40 days at the fastest, and if manual intervention is not carried out, the pine tree can be destroyed into pine forest in 3-5 years.
In order to control the spread of the disease, China invests a large amount of financial resources, firstly, the longhorn beetles serving as the spread media are prevented and killed, secondly, the pine trees died of the disease are eliminated, and the application range of the pine trees is strictly controlled. Many domestic institutions also develop researches for preventing and treating the disease, and the main research direction is to screen and prepare high-efficiency medicament varieties and dosage forms for punching and injecting medicaments. However, the existing injection medicine has a fatal weakness, and must be used at the temperature below 10 ℃ in winter, because the dosage of the current common low-content emamectin benzoate preparations such as 1-5.7% emamectin benzoate microemulsion and other products is large, generally about 30-50 ml, the dosage must be that after the medicine bottle is inserted after drilling and is injected with water, the medicine bottle is manually pulled out at least about 7 days, and the medicine injection hole is plugged by a wooden plug, vaseline or a healing agent.
Aiming at the defects of the existing injection agent in practical application, the inventor carries out improvement research, utilizes a high-content emamectin benzoate preparation and fully utilizes the characteristics of high activity and systemic property of emamectin benzoate to develop a 22.75% emamectin benzoate soluble solution, can effectively prevent and treat the pine wilt disease, simultaneously, the injection agent only needs 5-8 ml, a wooden plug is used for plugging a medicine injection hole after the medicine injection is finished, the prevention and treatment can be completed at one time, and the complicated steps that the medicine bottle is manually pulled out after the medicine injection is injected for at least 7 days at the temperature below 10 ℃ in winter according to the existing injection technology, and the medicine injection hole is plugged by the wooden plug, vaseline or a consolidant are avoided.

Test example:
first, example 1 forest dry injection test
The test method comprises the following steps: through batch drilling, the injection dry dosage is 5-8 ml, the absorption conditions of emamectin benzoate with different contents are measured after 24 hours, data are counted, and a curve graph of the content and the absorption conditions is drawn.
The test results are shown in figure 1, and it can be seen from figure 1 that the absorption is higher than 80% at a concentration of 21% to 30%, and the absorption forms a peak at a concentration of about 22.75%.
When the concentration is lower than 21%, due to the fact that the content of active substances is low, partial operation is not in place possibly during batch drilling, sawdust in partial holes is remained, the actual injection dry dose is not 5-8 ml, and after the concentration is higher than 30%, due to the fact that the viscosity of materials is gradually increased, absorption is gradually difficult.
Test of absorption condition of two, 22.75% emamectin benzoate soluble solution
The test method comprises the following steps: in Fuling white Crane forest park, the absorption of 22.75% methylamino abamectin benzoate soluble solution at different time points was examined, and the results are shown in Table 1.
TABLE 122.75% Emamectin benzoate soluble solution punch injection absorption (%)
As can be seen from Table 1, after 1 hour, the emamectin benzoate soluble solution has an average absorption rate of more than 65 percent, a maximum absorption rate of 90 percent and a fast absorption rate, and after 24 hours, most of the emamectin benzoate soluble solution can be absorbed by 98 percent and almost completely absorbed, so that the absorption rate is fast and the permeability is good.
Test for residual quantity of methylamino abamectin benzoate solution of three, 22.75%
The test method comprises the following steps: in Fuling white Crane forest park, the residual quantity of the effective components of the 22.75 percent methylamino abamectin benzoate soluble solution at different time points is examined, and the results are shown in Table 2.
TABLE 222.75 analysis table for residual quantity of effective components in emamectin benzoate soluble solution
From the results of actual measurement data in table 2, it is found that the residual amount of the 22.75% emamectin benzoate soluble solution in the tree body after punching and injection presents a parabola, the peak point is at 3 months to 8 months after punching and injection, then the residual amount gradually decreases, and the residual amount decreases to about 5% of the peak value after two years, but still is far more than the LC95 value of 0.75mg/kg, which indicates that the effective period is more than 2 years.
Test of control effect of emamectin benzoate 22.75% solution
The test conditions are as follows: at Fuling white Crane forest park, the annual inspection is 1 time, and the annual mortality rate of pine trees in perforated injection fields is recorded in detail. The control area was obtained from 2000 pine trees (labeled at the same time) in the same park near the forest. Remarking: the test area carries out the elimination of the epidemic trees every year in autumn.
The control effect in different years is counted by punching 2000 plants of the plant tree with the pesticide and contrasting 2000 plants of the plant tree with the pesticide, and the result is shown in table 3.
TABLE 322.75 statistics table for preventing and treating emamectin benzoate soluble solution in different years
As can be seen from the results in Table 3, the control effect of the 22.75% emamectin benzoate soluble solution is significantly higher than that of the control area.
According to the LC95 value of the effective components of the emamectin benzoate to the pine wood nematodes, the LC95 value is 0.75mg/L, and the water content of pine branches is about 50%. According to the calculation, when the dry weight of the emamectin benzoate in the pine branches contains the effective component amount of the emamectin benzoate more than 0.75mg/kg, the pine has immunity to the pine wilt disease. According to the measured data, after a 22.75% emamectin benzoate soluble solution is used for punching and injecting the pesticide into the pine tree (5 ml of pesticide is injected according to the diameter of 10-20 cm at breast height, 5ml is increased every 10cm at breast height), the concentration of the emamectin benzoate in the branches reaches 5-10 times of the LC95 value of the pine wood nematode 10 days after the pesticide injection, then the concentration of the emamectin benzoate continues to rise, the residual emamectin benzoate reaches the peak value 3-8 months after the pesticide injection, then the residual emamectin benzoate gradually falls, the average value after two years is 10% -20% of the peak value, but still reaches about 7-10 times of the LC 95. According to the analysis of the degradation rule of emamectin benzoate in pine trees, the residue is still more than 0.75mg/kg LC95 after 3 years, so the effective protection can reach three years.
The above embodiments are only preferred embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also within the scope of the present invention.
