Test 1
In 6-month middle ten days of 2021, the mite repellent spraying test was performed on the dyed fruit trees in the apple experimental field in the Lai mountain area of the Shandong tobacco terrace. Two adjacent insect-infected fruit trees in 5 directions in east, west, south and north of a test field are selected to carry out a spraying test, one of the two adjacent fruit trees in the 5 directions is selected to be a group in the example 1, and the other one in the 5 directions is selected to be a control group. Example 1 the group was sprayed with 2000-fold diluted mite repellent prepared in reference example 1, and the control group was sprayed with the same amount of sterile water at a rate of 250 kg/acre. And observing and counting before spraying and 5 th day after spraying respectively, observing and counting the number of live mites on 10 different layers of leaves of each plant in a way of holding a magnifier by hands, and calculating the pesticide effect.
The calculation formula of the drug effect is as follows: the oral cavity decline rate is 100% × (number of living insects before drug-number of living insects after drug)/number of living insects before drug, and the statistical data are shown in table 1.
TABLE 1 apple mite pest leaf spray test data
Analysis and statistics data show that after the product of the example 1 is sprayed on the group of the example 1, the reduction rate of the population of the apple leaves suffering from mite insect damage reaches 75.92%, and the control group does not play a role in preventing and controlling mites after being sprayed with sterile water, which indicates that the mite insect damage on the leaf surfaces of fruit trees can be effectively prevented and controlled by the application of the apple leaf mite insect control agent.
Test 2
In late 6 months in 2021, selecting a grape plantation in the Yantai Paolai area of Shandong, performing a mite control spraying test, and spraying and grouping: 6 adjacent grape plants in 5 directions in east, west, south and north of each test area are selected, 3 grape plants are randomly selected in each direction and are organized into an example 2 group, and the rest 3 grape plants are organized into a control group (sterile water) to carry out spraying tests. Wherein each plant selects 3 fruiting shoots, and each fruiting shoot selects 3 leaves for counting. The mite repellent is diluted 3000 times and applied, and the dosage is 300 kg/mu. Before and after spraying for 5 days, the total number of live mites is counted by adopting a hand-held magnifying glass observation method, and the prevention and treatment effect is represented by the insect population decline rate. The data statistics are shown in table 2.
TABLE 2 grape mite insect leaf spraying test data
Analysis and statistics data show that after the product of the example 2 is sprayed on the example 2, the population reduction rate of the grape leaves suffering from mite insect damage reaches 75.3%, and the control group does not play a role in effectively preventing and controlling mites after being sprayed with sterile water, which indicates that the mite insect damage prevention and control agent can effectively prevent and control mite insect damage on fruit tree leaf surfaces.
