Recently, Wang Yapei and his research group of the Department of Chemistry, Renmin University of China (RUC) published an article entitled “A Degradable Quaternary Ammonium–Based Pesticide Safe for Humans” on CCS Chemistry, an internationally renowned academic journal founded by the Chinese Chemical Society.
Based on the needs of the pesticide field, the research team has developed a class of environmental-friendly degradable pesticides based on silaketal linkages, which is expected to solve the problem of large toxicity and difficult degradation of traditional pesticides.
Abstract
Reducing the emission of agrochemicals hazardous to the environment and human health is one of the key targets of the UN’s Sustainable Development Goal 12. Herein, we report a kind of quaternary ammonium pesticides with an acid-cleavable silaketal linkage on their backbones that enables control of hydrolysis. These pesticides possess outstanding bactericidal and insecticidal properties but become harmless to humans and other organisms after hydrolysis. Depending on the conditions of use, the hydrolytic process can be controlled over the time range of10 min to 3 months. Both laboratory simulations and agricultural field demonstrations confirm that these pesticides can effectively protect crops from bacterial diseases and pests. At the same time, single-dose intragastric administration using diisopropylsilvloxy bisquaternary ammonium salt 9 (ISBOAS-9) in mice demonstrates its safety for multiple organs. Owing to the advantages of controllable degradability, environmental friendliness, and the low financial cost of these pesticides, this well-designed strategy holds great promise for the generation of environmentally harmless pesticides and the development of green agriculture.

The research team of Professor Wang has been engaged in scientific research in the fields of photothermal conversion, controllable emulsion, and green electronics for a long time, and focuses on their application innovation in the direction of skin medical engineering and smart agricultural and forestry materials and technology.
Facing the major strategic needs of the country, the team actively promotes the cross-integration of chemistry and other disciplines, and strives to solve the problems faced by the country in the fields of energy and environment, clinical medicine, agricultural science and technology by building close cooperation between disciplines.
CCS Chemistry is the first international journal independently established by the Chinese Chemical Society, dedicated to publishing inspiring research in all areas of chemical science and important advances in chemistry-related intersections.
