Australian Herbicide Resistance Initiative (AHRI)

Resistance management

Harvest weed seed control (HWSC) provides an opportunity to target future weed populations. Our most problematic weed species are prolific seed producers capable of establishing a large viable seed bank in just one season. However, very high proportions of weed seed are retained on upright stems and tillers of weeds at crop maturity. This creates the potential to target these seed during grain crop harvest to restricting inputs to the weed seed bank.
