In the production of non-polluted fruits, the proper use of pesticides is essential to ensure high yields and prevent plant diseases. However, it's crucial to select and apply these chemicals in a scientific and responsible manner to minimize environmental impact and health risks. This approach is key to ensuring that fruits are free from pesticide contamination and residues. **1. Methods to Prevent Pesticide Pollution** To reduce reliance on chemical pesticides, integrated pest management (IPM) strategies should be adopted. This includes using a combination of biological, physical, and chemical methods. For example, selecting disease-resistant crop varieties, applying microbial pesticides, and using techniques like trapping or winter control can significantly cut down on chemical usage. Additionally, thorough safety evaluations of commonly used pesticides must be conducted. These assessments should consider acute, chronic, and long-term effects, including mutagenicity, carcinogenicity, and teratogenicity. Based on this data, acceptable residue levels and safe intervals for application should be established. Proper application of existing pesticides is also vital. Accurate forecasting of pest outbreaks allows for timely and targeted interventions. Choosing the right pesticide, improving spraying techniques, and following recommended dosages can enhance effectiveness while reducing environmental harm and the development of resistance. Finally, developing safer alternatives such as low-toxicity, biodegradable, and bio-based pesticides is essential. Third-generation products like pheromones and sterilizing agents offer effective, eco-friendly solutions to pest control. **2. Principles for Pesticide Use** When producing green food, only approved pesticides should be used when necessary. The guidelines include: - Using moderately toxic plant-based, animal-derived, or microbial pesticides. - Allowing mineral-based pesticides like sulfur and copper compounds. - Permitting limited use of low-toxicity organic pesticides, with strict limits on frequency and dosage. - Strictly prohibiting the use of highly toxic and persistent pesticides during fruit storage. **3. Banned Pesticides** To meet safety standards, certain harmful substances must be strictly avoided. This includes heavy metals and banned pesticides such as malathion, parathion, methamidophos, chlorothalonil, and many others. These chemicals pose serious health and environmental risks and must not be used in pollution-free fruit production. **4. Approved Pesticides** A variety of approved options are available, including: - Microbial pesticides such as streptomycin, polyoxin, and Bacillus thuringiensis. - Animal-derived products like insect pheromones and natural predators. - Plant-based pesticides such as pyrethrins, neem oil, and garlic extracts. - Mineral-based products like sulfur and copper compounds. - Low-toxicity synthetic pesticides developed for safe agricultural use. By following these practices, farmers can produce high-quality, safe fruits while protecting the environment and public health.
