Abstract

Herbicides play an important role in weed control when it comes to ensuring a high and consistent yield in agriculture, but their effectiveness is often compromised by climatic variables. Therefore, improving the climatic adaptability of pesticides is crucial to ensure sustainable agricultural development. In this study, a novel bispyribac-sodium (BIS)–zeolitic imidazolate framework-8 (ZIF-8) nanopesticide (BIS@ZIF-8) with excellent multi-stimuli-responsive properties was synthesized. The nanopesticide BIS@ZIF-8 showed intelligent and efficient weed control. In addition, the BIS@ZIF-8 nanocomposite showed strong resistance to rainwater erosion on the leaf surface with a BIS retention rate of 76.26% under simulated rainwater, which was 41.54% higher than the BIS retention rate of the pure herbicide. Under UV light and acidic conditions, a high concentration of BIS was released from the BIS@ZIF-8 nanocomposite,

用于农业中智能除草的多刺激响应金属有机框架纳米农药

除草剂在控制杂草、确保农业高产稳产方面发挥着重要作用，但其效果往往会受到气候变量的影响。因此，提高农药的气候适应性对于确保农业的可持续发展至关重要。本研究合成了一种具有优异的多刺激响应特性的新型双ribac-钠（BIS）-唑基咪唑啉框架-8（ZIF-8）纳米农药（BIS@ZIF-8）。该纳米农药 BIS@ZIF-8 具有智能、高效的除草效果。此外，BIS@ZIF-8纳米复合材料在模拟雨水条件下对叶片表面的雨水侵蚀具有很强的抗性，其BIS保留率为76.26%，比纯除草剂的BIS保留率高出41.54%。在紫外线和酸性条件下，BIS@ZIF-8 纳米复合材料释放出高浓度的 BIS、
