How many hours did you spend out in the paddock with a chipping hoe when you were a kid? Do you still carry one in every ute? Chances are you know how effective they are; but wouldn’t mind if you never had to use one again! Australia has an unfortunate habit of claiming world-firsts in new species for the herbicide resistance lists. Fortunately, we have also been leaders in the development of new tools to help combat the problem. Enter: the revolutionary new chipping hoe! The latest of these developments is the world’s first site-specific mechanical weeder.

Did you know that rotary hoeing requires less energy than steaming? Or that offset discing requires less energy than microwaving? Well, that’s the case when it comes to controlling weeds. An epic effort to review 170 papers by a team from the University of Sydney (Guy Coleman et al) has shown that mechanical weed control options (eg. tillage) can use significantly less energy than thermal options (eg. heat) to kill weeds. Herbicide energy use sits somewhere in the middle.
