Striga hermonthica, an obligate root parasitic weed, poses a significant threat to cereal production in sub-Saharan Africa. Lowering Striga seed bank in infested soils is a promising strategy to mitigate infestation levels. The dependency of Striga seed germination on strigolactones opens up the possibility of a ‘suicidal germination’ approach, where synthetic germination stimulants induce lethal germination in the absence of a host. Implementing this approach requires active germination stimulants with a suitable formulation for field application. Here, we describe the development of slow-releasing granular formulation of two potent germination stimulants ‘Methyl Phenlactonoate 3’ and ‘Nijmegen-1’ and the assessment of their activity under Laboratory, greenhouse, mini-field, and field conditions.

颗粒配方独脚金内酯类似物对独脚金自杀萌发的评价

独脚金是一种专性根寄生杂草，对撒哈拉以南非洲的谷物生产构成重大威胁。降低受侵染土壤中的独脚金种子库是减轻侵染水平的一个有前途的策略。独脚金种子发芽对独脚金内酯的依赖性开启了“自杀性发芽”方法的可能性，其中合成发芽刺激剂在没有宿主的情况下诱导致命的发芽。实施这种方法需要活性发芽刺激剂和适合现场应用的配方。在这里，我们描述了两种强效发芽刺激剂“苯内酯甲酯 3”和“Nijmegen-1”的缓释颗粒制剂的开发，以及它们在实验室、温室、小田地和大田条件下的活性评估。
