Application


  • Impact of herbicide runoff: Research compares runoff losses and toxicity between residual and knockdown herbicides, including Fluroxypyr, when applied to sugarcane fields, demonstrating significant differences relative to traditional treatments such as Diuron. This study underscores the importance of selecting appropriate herbicide treatments for effective weed management while minimizing environmental impact (Silburn et al., 2023).

  • Herbicide resistance and management: A study focused on Florasulam-resistant flixweed in North China highlights the potential role of alternative herbicides, including Fluroxypyr, for managing resistant weed populations. The research provides insights into herbicide selectivity and efficacy, aiding in the development of more effective weed management strategies (Wang et al., 2021).

  • Herbicide pollution assessment: Utilizing a multi-dimensional approach, this study assesses herbicide pollution in catchment areas, discussing the implications of Fluroxypyr among other herbicides. It focuses on the ecological consequences of herbicide use and the necessity for accurate pollution assessment techniques to ensure environmental safety (Khan et al., 2020).
