As the temperature gradually rises, farmers who use pesticides should pay close attention to several key points. According to Tracy from China Pesticide Network, here are some important tips for more effective and safe pesticide application:
1. **Improve Pesticide Utilization and Adhesion**
When applying pesticides in open fields, it's essential to choose formulations that are resistant to rain, such as emulsifiable concentrates. These types of pesticides remain on plant surfaces for a longer time, making them more effective compared to powders or liquids. Crops like corn, green onions, ginger, and taro have waxy or hairy leaves, which can cause liquid sprays to form droplets and not fully adhere. To enhance effectiveness, consider adding adjuvants like silicone to improve coverage and absorption.
2. **Adjust Pesticide Concentration Based on Temperature**
Most pesticides become more effective at higher temperatures. Therefore, during hot seasons, it’s advisable to reduce the concentration of the pesticide solution. This is especially important for hormone-based pesticides, as high concentrations may lead to phytotoxicity. Always adjust the concentration according to the weather conditions to ensure safety and efficiency.
3. **Focus on Spray Quality and Coverage**
The quality of the spray plays a crucial role in the effectiveness of pesticide application. When spraying, the amount of pesticide that adheres to the leaf surface is limited. If the spray volume is too high, fine droplets may merge into larger drops and run off, reducing the actual amount of pesticide that remains on the plant. The ideal approach is to achieve uniform droplet distribution and full coverage without over-saturating the leaves. A good atomization system is essential to minimize waste and maximize efficiency. Additionally, make sure to spray thoroughly, especially on the underside of leaves where pests often lay eggs.
4. **Spray Safely and Avoid Toxic Exposure**
Pesticide application should always be done with proper safety measures. Wear protective clothing to avoid skin contact, and use a mask when handling volatile pesticides. Avoid spraying during the hottest parts of the day in summer—opt for early morning (before 9 am) or late afternoon (after 4 pm) instead. Continuous and prolonged spraying should be avoided to prevent both environmental harm and potential health risks. By following these guidelines, farmers can ensure safer and more effective pesticide use.
