Dual paraquat and glyphosate resistance in annual ryegrass

For the first time in WA, there’s been a confirmed case of glyphosate and paraquat resistance in annual ryegrass.

The discovery has prompted University of Western Australia weed researcher, Dr Roberto Busi, to research alternative double knock solutions. As Roberto explains, the findings have been a quantum leap forward in understanding how these resistant ryegrass populations can be effectively controlled with paraquat and pre-emergent herbicide combinations.
