Weed control and high standing stubble at planting

摘要

Weed control strategies — that will ensure growers are successful when implementing a stubble-retaining strip and disc system - have been identified. A GRDC investment, led by WA-based Crop Circle Consulting, aims to provide herbicide-use advice forwheat, canola and lupin crops grown under strip and disc systems.Trials in Mullewa and Binnu compared 18 different herbicide treatments in wheat planted with a disc seeder. Trials in Yuna, Ogilvie and Mingenew compared multiple herbicide treatments in both canola and lupins. Crop Circle Consulting and Research director Grant Thompson said the first-year trial results from these sites are encouraging, with a few options to choose from.“A mix of Boxer Gold with Quadrant applied after the three-leaf stage of wheat achieved good weed control for the best yield results at both sites,” Grant said.
