T/ZNX 001-2021 Technical Specifications for Unmanned Aerial Vehicle Pest Control of Tea Gardens

Scope

Main technical content: 6. Pesticide preparation 6.1 Field survey Before spraying pesticides, a field survey should be conducted to understand the growth period of tea and the occurrence of pests and diseases. 6.2 Preparation site Pesticide preparation should be carried out far from residential areas, livestock farms, and water sources. The cleaning of pesticide application equipment and drones should also be conducted away from these areas. 6.3 Scientific pesticide application 6.3.1 Strengthen pest and disease forecasting Enhance pest and disease forecasting for tea trees to timely grasp the dynamic of pest and disease occurrence. Strictly control the timing of pesticide application during the appropriate period and implement standardized prevention and control. 6.3.2 Correctly select pesticide varieties Use biological pesticides and targeted pesticides for prevention and control. Prioritize the use of microbial, plant-based, and mineral-based pesticides, which should be used outside the tea harvest season. Limit the use of highly effective, low-toxicity, and low-residue chemical pesticides; prohibit the use of highly toxic, highly dangerous, and long-residue pesticides. The selection of pesticides should comply with the provisions of NY/T 393. Control indicators are referenced in Appendix A. 6.3.3 Strictly implement spraying guidelines Follow the provisions of GB/T 8321 and pay attention to the rational rotation of pesticides. 6.3.4 Conduct destructive tests before application The dosage form, application time, concentration, and safety interval of pesticides vary in different environments. Three to seven days before operation, destructive tests should be conducted on the target tea trees to collect experimental data and ensure the safety of pesticide application and the target tea trees. 6.4 Mixing principles 6.4.1 Pesticides should be prepared and used immediately. 6.4.2 Pesticides with synergistic effects on target pests and d
