Guangxi: Nano‑pesticides effectively enhance the efficacy of aerial plant protection operations.

　　Nanomaterials that integrate the outstanding properties of “high efficiency, safety, cost-effectiveness, environmental friendliness, water-based formulation, and controlled release” Pesticide Water-based formulations, tailored to meet users’ diverse needs for pest control, disease management, and growth stimulation, deliver superior efficacy compared to conventional products. Pesticide The reduction exceeds 30%, according to information obtained by the reporter at the recent training workshop on formulating technical guidelines for using plant protection drones to apply aviation‑specific pesticides for controlling rice diseases and pests, held in Nanning, Guangxi.
　　At the conference, Guo Yongwang, Deputy Director of the Pesticide and Equipment Division at the National Agricultural Technology Center, stated that plant protection drones have experienced rapid, explosive growth over the past two years, owing to their fundamentally different spraying methods and operational efficiency compared with backpack sprayers and ground‑mounted boom sprayers. However, the lack of standards for drones, specialized formulations, and technical procedures has created numerous challenges for the industry’s development. Moreover, in the aerial application sector, the aircraft is merely the platform; the key lies in the formulation itself.
　　Guo Yongwang pointed out that the high efficiency of drone-based crop protection is beyond doubt, but the lack of compatible agrochemicals and the delayed formulation of relevant standards and regulatory provisions are hindering the rapid development of aerial crop protection in China. Based on feedback from practical applications, it is clear that not all… Pesticide All formulations are suitable for aerial crop protection. To advance the research and demonstration of specialized aerial‑application pesticides, and to evaluate the operational performance of various commercially available aerial‑spraying products, in 2017 the National Agricultural Technology Extension Center, in collaboration with the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences, South China Agricultural University, and other institutions, jointly conducted a field‑trial program titled “Evaluation of Field Performance of Plant Protection Drones” across key provinces nationwide. ShanSi Technology’s nano‑formulated, drone‑specific aerial‑protection product… Pesticide Participate in the process. According to the trial results, when applied via agricultural drones using aviation‑specific formulations, the spray droplets exhibit superior deposition density, more uniform distribution, and higher effective deposition rates on the rice canopy compared with conventional formulations. The aviation‑specific formulations developed by Shanshi Technology demonstrate characteristics and advantages that closely align with the ultra‑low‑volume application requirements of drone‑based spraying.
　　Huang Guangpeng, Director of the Guangxi Zhuang Autonomous Region Plant Protection Station, stated that in August 2017, the Guangxi Plant Protection Station, Shanshi Technology, and the International Joint Research Center for Precision Agricultural Aviation Application Technologies signed an agreement to advance the development of new aviation‑specific plant protection formulations and precision application technologies using plant protection drones. Pesticide The “Zero-Growth Action Cooperation Agreement” plans to leverage the strengths of all parties over a three-year period by selecting large-scale grain and cash‑crop producers within Guangxi, establishing demonstration bases for precision pesticide application using agricultural drones, conducting trials and demonstrations of novel aviation‑specific agrochemicals applied via drone, and developing key technical guidelines for drone‑based precision spraying tailored to different crops, pest and disease types, and drone models. The initiative aims to achieve scientific, rational, and efficient pesticide use while also exploring the formulation of corresponding technical standards.
　　Liang Bing, President of Shansi Technology, outlined the company’s product development journey. Nano Pesticide It is intended for substances that are insoluble in water. Pesticide In essence, this involves using various techniques to disperse its particles in water down to the smallest possible nanoscale, thereby achieving a greater number of… Pesticide Particles with larger surface areas facilitate better contact with the target, resulting in enhanced efficacy. Over the past two years, with strong support from the Guangxi Autonomous Region Plant Protection Station, various nano‑formulations have been tested across multiple locations in Guangxi. Pesticide Field efficacy trials of specialized aerial‑application pesticides for the control of diseases and pests have been conducted, yielding promising results.
