Proliferation of herbicide-resistant weeds demands re-evaluation of fundamental weed control objectives. Yield loss mitigation remains a priority, but limiting weed seed return (WSR) to the soil seedbank is key to preventing herbicide-resistant annual weeds from multiplying. The critical period for weed seed control (CPWSC) is the period of the growing season during which weed control can minimise weed seed production. The CPWSC provides a framework to limit WSR by targeting weeds during phenological stages critical for seed development. We aim to (a) introduce the CPWSC concept, (b) provide an example using Bassia scoparia as a model species and (c) offer a framework for future research.

杂草种子控制的关键时期：限制杂草种子回报的拟议框架

抗除草剂杂草的繁殖需要重新评估基本的杂草控制目标。减少产量损失仍然是一个优先事项，但限制杂草种子返回土壤种子库 (WSR) 是防止抗除草剂一年生杂草繁殖的关键。杂草种子控制的关键期 (CPWSC) 是杂草控制可以最大限度地减少杂草种子产量的生长季节时期。CPWSC 提供了一个框架，通过在对种子发育至关重要的物候阶段针对杂草来限制 WSR。我们的目标是 (a) 介绍 CPWSC 概念，(b) 提供一个使用Bassia scoparia作为模型物种的例子，以及 (c) 为未来的研究提供一个框架。
