How to prevent pesticides from harming humans

During the use of pesticides, due to the effect of airflow, the phenomenon that the drug mist diffuses and moves away from the wind is called droplet drift. When applying pesticides to a closed greenhouse, the drift characteristics of the droplets can be used to achieve uniform distribution throughout the shed. The wind speed and the airflow conditions around the applicator are one of the main factors that cause fog drift. The higher the wind speed, the farther the small droplets drift; even slightly larger droplets drift in the downwind conditions. Therefore, when people are outdoors, they may decide the time for spraying pesticides according to the wind speed. When the wind speed is measured, the wind speed recorder or wind anemometer can be used to operate.

In the spraying stage, the concentration of drug mist is not affected by the axial wind speed; in the stage after the spraying, the higher the velocity is, the greater the concentration of drug mist is at the same sampling time and the faster the velocity is, the faster the concentration of drug mist is decreased. This is mainly due to the influence of wind velocity on heavy fog. Drops caused by drift, with the passage of time, this phenomenon is less and less obvious.

The above output does not require much in the spraying stage, but has a greater impact on the stage after the spraying. Therefore, when this process is performed outdoors, it is necessary to understand the process of changing the wind speed, so that it is more convenient for us to control the concentration of pesticides. . The use of wind speed recorders, wind anemometers can not only measure the size of the wind speed is not a powerful data analysis and storage capabilities. Up to 60000 data can be stored (30000 for two parameters, 20,000 for three parameters, 15000 for four parameters, and so on), and data can be viewed on the host or imported into the computer. The calculation software carried at the same time can form a graph of the collected data and display it visually. The collected data can also be stored as an EXCEL spreadsheet file, allowing users to save and process data, or use specialized software for data processing, drawing bars, pies, and prints. Reducing our own waste of time in the data analysis process and facilitating us to look at the process of changes in wind direction wind speed has provided us with great help in changing wind speed and wind speed.

The concentration of pesticides will directly affect the quality of this crop. Now the country is paying attention to the inspection of pesticide residues. By using a wind direction recorder to understand the changes in wind speed, the pesticide is sprayed and the concentration of the pesticide is appropriately adjusted.
