Key Points

• Mateno Complete is a new herbicide to be released for the 2022 growing season, and this trial will give growers the opportunity to see it in the field prior to release.

​

Aim

To demonstrate the weed control efficacy and crop safety of a range of herbicides in wheat when used as an IBS or EPE application.

​

Background

Mateno Complete is a new herbicide being released to the market by Bayer Crop Science in 2022. It can be applied at either the pre-sowing or early post emergent timing; and controls a number of key grass and broadleaf weeds including annual ryegrass, barley-grass, wild radish and capeweed. The site was identified in late autumn 2020 to ensure a suitable burden of annual ryegrass, and canola seed was spread pre-sowing to ensure broadleaf weed control could be demonstrated. At the early post-emergent application, 572 plants per m2 of annual ryegrass and 197 plants per m2 of volunteer canola was counted in the untreated plots.
