Long-Acting Sustained-Release Hydrogel for Soil-Borne Pathogen Control in Chinese Herbal Medicine
The Chinese herbal medicine industry plays a crucial role globally, providing traditional remedies and significantly contributing to healthcare. Disease prevention and control in Chinese herbal medicine face unique challenges distinct from conventional plant protection methods. The distinctive requirements for disease control add complexity to disease management, necessitating specialized approaches. In this study, we developed a bio-based hydrogel (CSA-gel) using a straightforward procedure designed for the sustained release of azoxystrobin for soil disinfection with the aim of preventing fungal diseases in Chinese herbal medicine. The synthesized hydrogel was characterized using FTIR, zeta potential measurement, cryo-TEM, SEM, and elemental analysis. CSA-gel demonstrated a release duration of azoxystrobin for over 14 days, maintaining high antifungal activity throughout the entire release period. Additionally, CSA-gel exhibited the ability to release a significant quantity of calcium ions during pesticide release, fostering plant growth and enhancing plant disease resistance. The use of CSA-gel is anticipated to decrease both how often and how much pesticide is needed, highlighting the significance of our research in improving sustainable disease control in traditional Chinese herbal medicine farming.
期刊介绍:
The Journal of Polymers and the Environment fills the need for an international forum in this diverse and rapidly expanding field. The journal serves a crucial role for the publication of information from a wide range of disciplines and is a central outlet for the publication of high-quality peer-reviewed original papers, review articles and short communications. The journal is intentionally interdisciplinary in regard to contributions and covers the following subjects - polymers, environmentally degradable polymers, and degradation pathways: biological, photochemical, oxidative and hydrolytic; new environmental materials: derived by chemical and biosynthetic routes; environmental blends and composites; developments in processing and reactive processing of environmental polymers; characterization of environmental materials: mechanical, physical, thermal, rheological, morphological, and others; recyclable polymers and plastics recycling environmental testing: in-laboratory simulations, outdoor exposures, and standardization of methodologies; environmental fate: end products and intermediates of biodegradation; microbiology and enzymology of polymer biodegradation; solid-waste management and public legislation specific to environmental polymers; and other related topics.
