In daily farming activities, farmers often misuse pesticides due to improper handling, which not only reduces the effectiveness of the chemicals but can also lead to plant toxicity. This poses serious risks to human and animal health and causes significant losses in agricultural production. Therefore, it's essential for farmers to follow these important guidelines to ensure safe and effective pesticide use.
First and foremost, never use counterfeit, contaminated, or banned pesticides. Always use containers made of non-reactive materials such as plastic, glass, or ceramic—never metal, as it can cause chemical reactions that reduce efficacy or even create toxic byproducts. When mixing pesticides, use the "two-step dilution method": first mix a small amount of the concentrated pesticide with water, then add more water to reach the desired concentration while continuously stirring to ensure an even mixture. This helps maintain consistent potency and improves pest control.
To enhance the effectiveness of the pesticide, you can add a small amount of vinegar or a pesticide synergist before application. For better adhesion, consider adding 6501 spreader at a 3,000 times dilution or 0.1% washing powder. When controlling cockroaches, adding a small amount of alcohol can boost effectiveness and reduce resistance.
It is best to spray during sunny afternoons when humidity is low. Avoid spraying in high humidity, fog, or during dewy conditions, as this can reduce the effectiveness of the pesticide. When applying, make sure the spray is fine and uniform so that the liquid doesn’t drip from the leaves. When targeting cockroach pests, be sure to spray the underside of the leaves, and for mites, focus on the dense areas where they tend to hide.
Follow the recommendations from local agricultural protection departments. Apply safe pesticides during the growth stages when pests are most vulnerable. When using chemical pesticides, protect beneficial insects by choosing products that are less harmful to them and avoid spraying during their breeding periods. Rotate pesticide types regularly to prevent resistance. Never apply the same pesticide repeatedly for the same pest or disease.
When mixing pesticides, strictly follow the mixing instructions provided on the label. Avoid long-residual pesticides whenever possible, and do not use broad-spectrum insecticides early in the crop growth cycle. Spray only when pest populations reach the economic threshold, during the weakest phase of the pest’s life cycle, when they are hidden, and when crops are strong and natural enemies are not active.
Always carefully control the dosage, concentration, and safety interval of the pesticide. Use the lowest effective concentration within the recommended range to minimize environmental impact and cost.
Here are some effective pesticide application techniques:
1. **Localized Spraying**: If certain areas of the crop are severely damaged, target those spots. This reduces overall pesticide use, lowers costs, and protects beneficial insects.
2. **Ground Spraying**: Applying pesticides directly to the ground can effectively kill pests while minimizing harm to natural enemies.
3. **Selective Application**: Use specific insecticides that target only the pests without harming beneficial species.
4. **Microbial Preparations**: For example, *Beauveria bassiana* can be used to control cockroach infestations safely and effectively.
5. **Smart Mixing**: Combine pesticides with different modes of action to delay resistance and improve efficiency. For instance, pairing a slow-acting insecticide with a fast-acting pyrethroid can speed up pest knockdown while reducing damage to natural enemies.
6. **Integrated Pest Management (IPM)**: Combine chemical control with cultural and biological methods to reduce reliance on pesticides, lower usage, and protect the ecosystem.
Proper and skillful pesticide use is key to ensuring safety and effectiveness. By following these guidelines, farmers can significantly reduce the risk of accidents and promote sustainable agriculture.
