High levels of adoption indicate that harvest weed seed control is now an established weed control practice in Australian cropping

Not so long ago, harvest weed seed control (HWSC) was only used by a minority of early adopting grain growers. Now it has gone mainstream and pretty soon just about everyone will be doing it. This is the result from a national Australian GRDC grower survey reported in a recent scientific publication by Michael Walsh from University of Sydney. Every few years GRDC fund a large grower practices telephone survey. The most recent survey was conducted by CSIRO in 2014, and they collaborated with Michael to design the HWSC questions. The survey revealed 43% of Australian grain growers are currently…

harvest weed seed control Harvest Weed Seed Control Systems are Similarly Effective on Rigid Ryegrass

The paper, Harvest Weed Seed Control Systems are Similarly Effective on Rigid Ryegrass, was conducted as field research led by Michael Walsh. This was in itself a major logistics task. AHRI purchased, with GRDC support, a John Deere combine grain harvester, which was transported across the nation from west to east at wheat harvest time. Thousands of kilometres were traversed to conduct this research! In 24 locations on normal commercial farm fields across the vast grain belts of Western Australia, South Australia, Victoria and New South Wales at wheat harvest time, the harvest weed seed control (HWSC) techniques of narrow windrow with…
