Xia Jingyuan, Director of the National Agricultural Technology Extension Service Center, recently spoke to reporters at the 23rd China Plant Protection Information Exchange & Pesticides Trade Fair. He highlighted the ongoing efforts to replace highly toxic pesticides with safer alternatives. Following the initial phase of the project launched in 2007, the center plans to continue the initiative from 2008 to 2010, aiming to further reduce the use of hazardous chemicals in agriculture.
Since the start of the alternative pesticide testing and demonstration project in 2005, a total of 132 field trials and 77 large-scale demonstrations have been conducted. As a result, 29 alternative pesticide formulations and 43 corresponding application techniques have been identified. These include substitutes for five highly toxic organophosphorus pesticides, such as amiprophos-methyl. The program has not only helped reduce cases of human and animal poisoning and environmental harm but also improved farmers' knowledge of safe pesticide use. This has contributed significantly to pest control, crop quality improvement, and the safety of agricultural products.
Despite these achievements, Xia pointed out that challenges remain. Due to the short implementation period since 2005, some foundational work is still incomplete. The promotion of new technologies requires more effort. With changing climatic conditions, environmental shifts, and evolving planting structures, migratory pests and epidemic diseases have become increasingly problematic. In some cases, there are limited alternative solutions available, and the depth of research on application techniques and risk assessments is insufficient. Some technologies are not yet fully mature, and training and demonstration programs have not been widely adopted.
To address these issues, the center plans to extend the project through 2010. The 2008 plan includes six main tasks: first, identifying and screening active ingredients for various crops, including rice, cotton, wheat, corn, apple, citrus, vegetables, tea, soybeans, sugarcane, peanuts, and litchi. Second, conducting field experiments and developing supporting technologies. Third, performing risk assessments, including resistance development and non-target ecological impacts. Fourth, demonstrating optimized application techniques. Fifth, setting up large-scale demonstration areas across 12 crops. Finally, promoting awareness and providing technical training through educational materials, on-site meetings, and workshops.
This comprehensive approach aims to ensure safer, more effective pest management while protecting both the environment and public health.
