1.Place ：Dongzhuangtou Village, Anqiu, Weifang City, Shandong Province,China

2.Medication time：August 15, 2019

3.Test crop：Strawberry

4. Strawberry experimental data

Data from experiments on strawberries (period: March 7th, 2021 to March 12th, 2021)

5. The number of experimental farms is a total of 128 farms, of which 32 farms have the second time.

6. After 24 hours of prevention and control, observe 30 parts (arbitrarily selected) in each 300 (991m2) greenhouse, and each farmer has experimented with an average of more than 3 large sheds. According to the precise results obtained under this condition.

7. Control time: between 9 am and 5 pm.

8. The proportioning concentration is 500 times, and the consumption is 150 liters for each greenhouse.

9. Most of the control methods are high-pressure spraying, and the results are obtained from the back of the leaves.

10. The density of mites is higher in seasonal characteristics, so no additional medicines are used

11. Implications for experimental results

12. The first control capacity is about 80-85% on average, and the control capacity of farmers who complete the second control after 4-5 days is increased to more than 90%

13. In order to evaluate the continuity, the 30 farmers who only received the first control and the 30 farmers who completed the second control are the targets. The density of mites is being compared and evaluated, and only one shot will be taken. The continuity of the farmer’s family after taking the medicine twice is divided into 10 days and 15 days. Continue to observe and confirm the density of mites.

14. In the high-pressure nozzle mode, due to the performance difference of the nozzles, there is a difference in the ability to prevent the agent. In order to select the nozzle suitable for the drug, the appropriate nozzle is being tested.

15. In the above experiment, the farmers whose control ability is less than 50% were analyzed, and it was found that there were a few cases where the control ability was reduced in this way:

(1) Do not clean the dilution barrel, but dispense the previously used medicine in the residual state

(2) Timing with amino acids and the like

(3) Excessive use of mineral powder during preparation

(4) In accordance with the above conditions, when using Chinese medicine to kill mites, it is best to prohibit other products

16.Impact on the sub-house

Until the previous day, no effect was found on fertilization and fruit setting when the flowers were in full bloom.

17.Impact on bees

After the medicine was given, when the bees were put in again, the behavior of the bees did not have any special problems, and the death problem was also at a normal level.
