Our extension officer Kirrily Condon recently wrote an AHRI insight entitled “Thermal weed control – just hot air, or site-specific reality?” (read it here: https://ahri.uwa.edu.au/thermal-weed-control-just-hot-air-or-site-specific-reality/)which looked at work by a team from the University of Sydney. Guy Coleman and his colleagues reviewed 170 papers, which demonstrated that mechanical weed control options, like tillage, can use significantly less energy than thermal options, like heat, to kill weeds. Herbicide energy use sits somewhere in the middle. We chat with Guy to find out a bit more.
