摘要

中草药产业在全球发挥着至关重要的作用,它提供传统疗法,为医疗保健做出了巨大贡献。与传统的植物保护方法不同,中草药的病害防控面临着独特的挑战。对病害控制的独特要求增加了病害管理的复杂性,需要采用专门的方法。在本研究中,我们采用一种简单的方法开发了一种生物基水凝胶(CSA-凝胶),用于持续释放唑啉草酯进行土壤消毒,目的是预防中药材中的真菌疾病。傅立叶变换红外光谱、ZETA 电位测量、冷冻-TEM、扫描电镜和元素分析对合成的水凝胶进行了表征。CSA 凝胶的唑螨酯释放时间超过 14 天,并在整个释放期间保持较高的抗真菌活性。此外,CSA-凝胶还能在农药释放过程中释放大量钙离子,促进植物生长,增强植物抗病能力。预计 CSA-凝胶的使用将减少农药的使用频率和用量,这凸显了我们的研究在改善传统中药材种植的可持续病害控制方面的重要意义。

Long-Acting Sustained-Release Hydrogel for Soil-Borne Pathogen Control in Chinese Herbal Medicine

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.
