Ahri Snapshots

On today’s AHRI Snapshots, we’re catching up with previous AHRI Masters student Martina Badano.Martina worked with Dr Roberto Busi back in 2019 on rapid on-farm testing.Her paper “Rapid On-Farm Testing of Resistance in Lolium rigidum to Key Pre- and Post-Emergence Herbicides” has just been published. We’re going to find out more about it.Here's some more detail on the paperOverreliance on herbicides for weed control is conducive to the evolution of herbicide resistance.Lolium rigidum (annual ryegrass) is a species that is prone to evolve resistance to a wide range of herbicide modes of action. Rapid detection of herbicide-resistant weed populations in the field can aid farmers to optimize the use of effective herbicides for their control.The feasibility and utility of a rapid 7-d agar-based assay to reliably detect L. rigidum resistant to key pre- and post-emergence herbicides including clethodim, glyphosate, pyroxasulfone and trifluralin were investigated in three phases: correlation with traditional po
