Herbicides for barley grass management

Barley grass continues to be a persistent grassy weed in low rainfall farming systems and current farming practices have selected for increased seed dormancy. This change in seed dormancy has resulted in Barley grass germinating later, and being much harder to control with knockdown and pre-emergent herbicides. In 2018 a range of herbicide strategies was tested for their effectiveness on a high density population of Barley grass.

大麦草始终是低降雨耕作系统中顽固存在的禾本科杂草，而现行耕作措施已促使其种子休眠特性增强。这种种子休眠性的变化使得大麦草发芽期延后，且更难以通过灭生性除草剂与芽前除草剂进行防除。2018年，研究人员针对高密度大麦草种群，对多种除草剂施用方案的防除效果开展了测试。
