Summer Weed Survey of WA Cropping Districts

In 2018, a number of grower network meetings concluded that correct identification of summer weeds and their management was an important local issue. It was also identified that new species of summer weeds are becoming more prevalent and control is becoming problematic and costly. In response, the summer weed survey of WA cropping districts commenced. In-paddock surveys were conducted in 197 paddocks over the summers of 2019-20 and 2020-21 to identify the diversity and abundance of summer weed species present across the GRDC Western region. The surveys covered the 6 agro-ecological zones (Agzones).Aims:Conduct 197 in-paddock surveys in both 2019-20 and 2020-21 to identify the composition of summer weed species present across the GRDC Western region covering the 6 agro-ecological zonesExpand the understanding of WA’s current in-paddock summer weed floraBetter inform possible future initiatives on identification and management of summer weeds
