The sustainability of the Australin grains industry is threatened by the continuing evolution and widespread expansion of herbicide resistant weed populations across the crop production regions. The resulting loss in herbicide efficacy is forcing producers away from the environmentally friendly practices of stubble retention and reduced tillage in an effort to control herbicide resistant weed populations. This research is aimed at conserving a novel mode of action herbicide with efficacy on resistant Lolium rigidum populations. The success of this project will inevitably lead the pesticide industry to adopt this approach for future product development.

澳大利亚谷物行业的可持续性受到作物生产地区抗除草剂杂草种群的持续进化和广泛扩张的威胁。由此造成的除草剂效力的损失迫使生产者放弃残茬保留和减少耕作的环境友好做法，以控制耐除草剂的杂草种群。本研究的目的是保护一种新的作用模式的除草剂的效果，对抗性硬直黑麦草种群。该项目的成功将不可避免地导致农药行业在未来的产品开发中采用这种方法。
