In Australia, the adoption of no-till farming systems is increasing; however, weeds have become one of the major biotic constraints to crop production. Weeds cost the Australian grains industry a staggering $3.3 billion annually in control measures and lost production. The adoption of conservation tillage has increased reliance on herbicides for weed management. Annual ryegrass, wild radish, wild oats, feathertop Rhodes grass, windmill grass, fleabane, barnyard grass, and sowthistle are some of the major weeds that dominate the crop growing regions in Australia. The introduction of herbicide-tolerant crops have further reduced herbicide options, leading to the evolution of many herbicide-resistant weeds. Therefore, a strategy following the principles of integrated weed management would help to preserve the available herbicide options. In addition to different weed management options, different weed research topics will be discussed during the presentation.
