Mixing herbicides wins again

What sort of person goes to a cocktail party and sticks strictly to beer?

A smart one! We all know that mixing drinks can hurt the next day.

We can’t say the same for herbicide mixing though. The smart farmers and agronomists are mixing two or more herbicides targeting the same resistant weed to delay resistance and maximise weed control, and the science is supporting this approach.

AHRI researcher Roberto Busi is a long-term advocate of herbicide mixing and in his recent paper which describes some computer modelling that he undertook with the help of Michael Renton.

Revealing canola’s super-powers

This AHRI Insight is a follow-up on an earlier article ‘Crops are doin’ it for themselves’ to where we investigated the complex interactions of competitive crops and their weed suppression powers.

While that paper focused on cereals, in this one we will consider the mechanisms at play in canola, a crop from the mustard family, long known for its allelopathic ability and yet the exact mechanisms are still shrouded in mystery.

Keep mixing herbicides

Roberto recently completed a project with GRDC investment where he sampled ryegrass from 17 paddocks across eight farms in Western Australia to see if there are benefits of proactively testing for herbicide resistance.  Across these tests, he found ryegrass that was resistant to Clethodim (Select) or Butroxydim (Factor) but no ryegrass that was resistant to the mix of the two. The same went for the pre-emergent herbicides as well, no resistance to mixes.

AHRI insight – the 100 is up!

We’re undecided whether we should picture the AHRI communication team cutting through a massive banner as we run onto the ground or raising our bats in the air at the MCG after a long day in the middle. It’s been a long innings and is one that we have enjoyed immensely.

To celebrate the 100th AHRI insight we’re reflecting on what have been the big stories that got you excited and made the biggest impact.
