Epic WA focus paddock project shows we’re having a win

Every parent knows that we simply can’t have favourites. We must love each of our children equally.

We at AHRI shouldn’t have favourites. We love all weeds research papers equally, but this paper is perhaps a little more equal!

It is the work of Martin Harries from DPIRD involving a six-year focus paddock survey with data from 184 paddocks spanning 14 million hectares of cropping land in Western Australia, made possible with GRDC investment.

Martin has recently published the weeds aspect of this research as part of his PhD and reported that we’re having a win with weed control in WA.

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.

Don’t delay sowing to beat ryegrass

Work up, work back, seed. That was the system.

And now we have seed early at all costs, dry if necessary, and get the crop up and away on the first rain.

But what does this do for weeds? Should we delay sowing and wait for a knockdown, or have we got it right?
