United KingdomResearchers from La Trobe University have discovered that annual ryegrass, the most damaging weed in Australian grain systems, can adapt to drought stress by adjusting its growth and reproductive patterns. This adaptation makes the weed more resilient and challenging to manage, especially as climate conditions become more variable. Published in Scientific Reports, the study found that herbicide-resistant populations of ryegrass can thrive under moderate drought conditions, producing significantly more leaves and tillers. Even under severe drought, these plants can survive and reproduce, maintaining higher leaf water content and flexible flowering times. The findings suggest that annual ryegrass may pose an ongoing threat in drier seasons, particularly where herbicide-resistant populations are present. Lead researcher Dr. Ali Bajwa emphasized the need for localized management strategies, noting that resistant populations do not suffer significant fitness costs under stress and may perform better than non-resistant ones.
