壬酸是广泛存在于动植物体内的脂肪酸,是一种触杀性、非传导、速效性的广谱除草剂,通过破坏细胞膜使植物细胞很快丧失生理功能。壬酸低毒,对环境影响较小,作为一种植物源除草剂具备广阔的的应用前景。近年来,北京市积极引入壬酸防除检疫性杂草——三裂叶豚草。为了实现用最低浓度、最低剂量达 Pelargonic acid is a fatty acid widely found in animals and plants. It is a broad-spectrum herbicide that is contact-killing, non-conductive and quick-acting and can quickly lose its physiological function by disrupting the cell membrane. Nonanoic acid has low toxicity and little impact on the environment. It has a broad application prospect as a plant-derived herbicide. In recent years, Beijing Municipality actively introduced nonanoic acid against quarantine weeds - Crassulaceae. In order to achieve the lowest concentration, the lowest dose of up to
