In recent years, due to the requirements of environmental protection and food safety, traditional dosage forms such as emulsifiable concentrate and powder are being phased out, and environmental protection agents represented by suspension agents and water dispersible granules have become the focus of research and development in the industry. Experts suggested that enterprises should increase scientific and technological innovation in this field, fully exchange and study, and jointly promote the level of pesticide preparations in China. This is the information obtained by the reporter from the 14th Shandong Provincial Pesticide Information Exchange Conference and the 7th Pesticide Processing Technology Training Course held in Qingdao on August 25.

It is understood that the suspension agent has the characteristics of avoiding the use of any solvent, high biological activity, safety and environmental protection, and will lead the development of pesticides in the future. At present, it is also a rapidly developing agent in China. As of January 16, this year, the total number of suspended agent registrations was 1922, accounting for about 7.3%, making it the third largest pesticide dosage form in China.

Li Zhonghua, vice president of the China Pesticide Industry Association, said that China's pesticide processing technology has made great progress in recent years, and the formulation is becoming more and more scientific. However, it is undeniable that the pesticide industry is still facing many challenges, and traditional formulations such as emulsifiable concentrates will be phased out. In the future, China's pesticide industry should increase scientific and technological innovation and strengthen the research, development and industrialization of green ecological pesticides. Enterprises should strengthen cooperation, share resources and jointly promote the development of China's pesticide industry.

Through years of efforts, new pesticide formulations in China have achieved rapid development. By the end of 2013, the formulation structure of pesticide products had been significantly optimized, the proportion of traditional formulations had gradually declined, and suspension agents and water dispersible granules had become the main force. In the future, pesticide formulations should be developed in the direction of water-based, granulated, labor-saving, slow-release, economical and refined, and the pesticide formulations should be selected based on the physical characteristics of the original drug, the biological activity and mode of action of the active substances, the biological characteristics of the control object, the requirements of the use technology, the impact of the climatic and environmental conditions during use, processing costs and market competitiveness.

At present, the quality of suspension agent products in the domestic market is uneven, and some products still have poor physical stability. Long-term storage is prone to serious water separation, stratification and precipitation, and some even agglomeration, which seriously affects and restricts the production, sales and use of suspension agent in China. In the future, long-term storage stability and synergistic effect will be the focus of research and development of suspension agent. Through the analysis of suspension agent formula design, high-quality and stable suspension agent products can be processed by selecting high-quality technical drugs, suitable surfactants and effective additives.
