When preparing pesticides, it is essential to accurately measure the dosage and concentration, ensure personal protection, use appropriate equipment, and pay attention to environmental safety. Below are specific precautions:

1.Accurate Measurement of Dosage and Concentration

Calculate the pesticide dosage and dilution concentration based on factors such as the target pest, crop type, and application area. Strictly follow the instructions on the pesticide label—do not arbitrarily increase or decrease the dosage, as this may reduce effectiveness or cause phytotoxicity.

2.Personal Protective Measures

When handling pesticides, wear protective clothing, masks, gloves, and goggles to prevent skin contact and inhalation. If pesticide comes into contact with skin, rinse immediately with plenty of water. If it splashes into the eyes, flush with clean water and seek medical attention promptly.

3.Use Suitable Equipment

Use clean, impurity-free, and corrosion-resistant measuring tools and containers, such as graduated cylinders, measuring cups, and dedicated pesticide sprayers. Avoid using beverage bottles or food containers to store pesticides to prevent accidental ingestion or misuse.

4.Follow the Correct Mixing Order

When mixing multiple pesticides, follow the proper sequence. Generally, first add wettable powders or dry formulations to water, stir thoroughly to form a stock solution, then slowly pour in liquid pesticides (e.g., emulsifiable concentrates) while stirring continuously. If foliar fertilizers are included, they are usually added last.

5.Prepare Fresh Solutions

Pesticide solutions should be used immediately after preparation and not stored for long periods. Some pesticides may undergo chemical reactions after mixing, leading to reduced efficacy or the formation of harmful substances.

6.Keep Away from Fire and Water Sources

Many pesticides are flammable, explosive, or toxic. Keep them away from open flames and heat sources to prevent fires or explosions. Additionally, avoid preparing pesticides near drinking water sources, ponds, or other water bodies to prevent contamination.

7.Prevent Environmental Pollution

Prepare pesticides in well-ventilated areas to avoid the buildup of fumes. If spills occur, clean them up immediately to prevent soil and environmental contamination. Do not discard empty pesticide containers carelessly—collect and dispose of them properly according to regulations.

8.Label Clearly

Label prepared pesticide solutions with the name, concentration, and preparation date to prevent misuse or accidental exposure.
