The growing demand for eco-friendly bio-based agrochemicals with lower health hazards and optimal pest management options boosts the production and utilization of biopesticides. This review provides a comprehensive overview of two toxic weed species Datura alba (Solanaceae family), and Calotropis gigantea (Asclepiadaceae family) with a specific focus on extraction with various solvents, phytochemistry, and biopesticidal activities. The data presented in this article shows that these two toxic weeds species have been studied and reported for biopesticidal activities like antifeedant, ovicidal, insecticidal, larvicidal, antibacterial, and repelling ability against various insects/crop pests. Phytochemical analysis shows that these two weed species have distinct biochemical profiles. However, studies lack systematic screening of the biochemical profiles. In addition, the review highlights the gaps in previous research and suggests that there is a need for well-detailed phytochemical profiling, spectrum of action and mode of action for the future use of these weed plants in the development of biological control agents.

来自曼陀罗和巨型甘油草的潜在生物农药：提取、分析和报道的化合物


对健康危害较低和最佳害虫管理选择的环保生物基农用化学品的需求不断增长，这促进了生物农药的生产和利用。本文全面概述了两种有毒杂草 Datura alba （Solanaceae 科） 和 Calotropis gigantea （Asclepiadaceae 科），特别关注各种溶剂的提取、植物化学和生物农药活性。本文提供的数据表明，已经研究和报道了这两种有毒杂草的生物农药活性，如抗喂食、杀卵、杀虫、杀幼虫、抗菌和驱除各种昆虫/农作物害虫的能力。植物化学分析表明，这两种杂草具有不同的生化特征。然而，研究缺乏对生化特征的系统筛选。此外，该综述强调了以前研究的差距，并建议需要对这些杂草植物未来在生物控制剂开发中使用这些杂草植物进行非常详细的植物化学分析、作用范围和作用方式。
