US00084 - Innovative crop weed control for northern region cropping systems
Herbicide resistant weeds have major impact on grower profitability. In the northern cropping zone, problematic weeds of significance include annual ryegrass, wild oat, sow thistle, African turnip weed, wild mustard and fleabane (in winter cropping) and barnyard grass, Feathertop Rhodes grass, fleabane, liverseed grass and windmill grass (in summer cropping systems).
This investment will establish the extent of herbicide resistance in these dominant weed species, characterise specific weed biology and identify the occurrence and in-crop population densities of these weed species across the GRDC Northern Region. The investment will also explore integrated weed management options including herbicide innovation, crop competition, strategic weed control and engineering weed control solutions.
