Test cell: 2 trees per cell, around which guard rows are set, each treatment is repeated 4 times.
Time of application: the test is carried out for 1 time in 10 middle ten days, and at the moment, the positive value citrus panonychus ulmi stage is adopted, and the drug application time adopts a Tengfei brand 3WBS-16 knapsack sprayer to carry out drug application, so that the front and back sides of the leaves are uniformly dosed.
Experimental investigation: the number of live mites was recorded after each of the three days of investigation at 3d, 10d and 15d after the application treatment. Five azimuth marks in the north and south of the tree are tender in each district during investigation, 25 leaves are investigated in each tree, the number of live mites on 50 leaves is investigated in total in each district, the leaves are directly observed by using a handheld magnifying glass, and the number of mites is counted.
The drug effect calculation method comprises the following steps:
direct impact on crops: during the test period, field observations were made at irregular intervals, and no effect of the test agent on citrus growth and other non-target organisms and predatory mites was found.
The results of the field efficacy test are shown in the following table:
table 4: field efficacy test result of diafenthiuron and compound of formula I on panonychus citri
As can be seen from the field efficacy test in the table, the diafenthiuron and the compound of the formula I have better prevention and control effects on the citrus panonychus, and the prevention and control effects on the citrus panonychus after 15d and 36% of the compound of the formula I, diafenthiuron water dispersible granules (1:5) reach 96.54%.
Example 5: compound of formula I and fluazinam for field efficacy test of panonychus citri
The test is based on: GB/T17980.11-2000 "pesticide field efficacy test criterion (one) acaricide for controlling full-claw mites of orange".
Test target: panonychus citri (Panonychus cirtri).
Test site: the citrus tree planting density is consistent, the water and fertilizer management is consistent, and the local scientific agricultural practice is met.
Cell arrangement: each cell was repeated 4 times for 2 citrus trees.
And (3) test design: the trial set 5 drug treatments, 1 placebo treatment, and a total of 6 treatment groups. The experiment is carried out on 5 days of 8 months in 2019 for 1 time, the dosage of each citrus tree is 4kg, and the industrial and agricultural 16-type knapsack sprayer is used for spraying the whole plant, so that the spraying is uniform as much as possible, and the front and back surfaces of the leaves and the branches are sprayed.
The investigation method comprises the following steps: five azimuth marks in the north and south of the tree were made for each plot, and the number of active mites on 25 leaves was investigated in total. And observing leaf surfaces by using a handheld magnifier, and counting the number of mites.
Investigation time: the mite population was investigated before the test, and the number of active mites was recorded after 1d, 3d, 10d, and 15d each of the treatments.
The drug effect calculation method comprises the following steps:
results of field efficacy test investigation:
table 5: field efficacy test result of compound of formula I and fluazinam on panonychus citri in 2019
The pesticide is applied to the same land in the orange garden in the Taiping town of Nanning, guangxi province on 7 and 25 days and on 8 and 3 days 2021 in 2020, and the experimental design and experimental method are as described above, and the field pesticide effect after the pesticide is applied in 2021 is statistically investigated.
Table 6:2021 results of field efficacy test of compound of formula I and fluazinam on panonychus citri
From the field efficacy test results in 2019 (Table 5), the compound of the formula I and fluazinam has good control effect on panonychus citri. After the medicine is taken for 1d and 3d,30% of the compound shown in the formula I and fluazinam water dispersible granule (1:1), 35% of the compound shown in the formula I and fluazinam wettable powder (1:4) and 18% of the compound shown in the formula I and fluazinam suspending agent (1:8) have good quick-acting property, and the total control effect is more than 75%. After the medicine is taken, the control effect of 15d and 18% of the compound of the formula I, fluazinam suspension (1:8) reaches 97.40%, and the treatment duration of each preparation example is good.
2021 field investigation results (table 6) show that the compound of the formula I and fluazinam can effectively slow down the drug resistance development of pest mites, and after three years of continuous administration on the same land, the single dose of 25% of the compound of the formula I and 40% of the fluazinam suspension obviously reduces the control effect on citrus panonychus.
In conclusion, through an indoor biological test and a field efficacy test, the pesticide composition provided by the invention has a good control effect on pest mites, can effectively control the harm of the pest mites of crops, delay the drug resistance development of target pest mites, reduce the dosage of pesticides, and is safe to natural enemy organisms and environment-friendly.
