This research paper, “iHSD mill efficacy on the seeds of Australian cropping system weeds” by M Walsh, J Broster, S Powles, quantifies the efficacy of Harrington Seed Destructor (HSD) mills in destroying weed seed in the grain harvester chaff fraction.
The widespread evolution of multiple herbicide resistance in the most serious annual weeds infesting Australian cropping fields has forced the development of alternative, non-chemical weed control strategies, especially new techniques at grain harvest.
Global grain production is under threat from the escalating evolution of herbicide-resistant weed populations. Worldwide, herbicide-reliant grain crop production systems have driven the proliferation of herbicide resistant populations of major weed species.
