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.

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.
