Australian Herbicide Resistance Initiative (AHRI)

Hoe, hoe, hoe and away weeds go!

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.

Thermal weed control – just hot air, or site-specific reality?

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.

Narrow row spacing – more crop, fewer weeds

It would be really nice if research told us that fast food, chocolate and lollies were better for us than a balanced diet. We could eat what we want without a care in the world. There are those who believe that junk food is good for you, but the science doesn’t support this belief. It would also be nice if research told us that wide row spacing increased grain yield while improving weed control. Wide row spacing is cheap and convenient. Fewer tines or discs to pull, easier stubble handling, good herbicide safety, less fuel and horsepower required, cheaper machinery,…
