The Harrington Seed Destructor (iHSD) is a means to control weed seeds by way of mechanical impact trauma to the seed.
The Harrington Seed Destructor is integrated directly into the chaff stream of a combine harvester providing harvest time weed control and prevents the vast majority of weed seeds from entering the soil seed bank.
The Australian Herbicide Resistance Initiative (AHRI) has determined that the iHSD destroys up to 99% of targeted weed species that enter them.
The iHSD has major advantages over many traditional weed control methods.

Watch: A description of how the iHSD is built and how it works.
The Harrington Seed Destructor is the culmination of 20 years of development that started with an idea from WA farmer; Ray Harrington.
Ray knew that Australian farmers were fighting a war to eradicate weeds in their cash crops. From the 1970s the introduction of cheap, highly effective herbicides has been the farmer’s main defence against weed infestation, but over the course of time through natural selection, herbicide resistant strains of weeds have become a critical issue in many areas of Australia across all staple crop varieties.

Ray’s idea was brilliantly simple - what if there was a way to reliably destroy weed seeds mechanically during the harvest process? Enter iHSD technology: the chaff stream from a combine harvester is intercepted and fed directly into a high speed mill that pulverises the chaff, including weed seeds that would otherwise pass through the harvester and be returned to the field.
Enter the Australian Grains Research and Development Council (GRDC), who understood the importance of Ray’s idea and provided funding and UniSA provided research and development expertise to further develop iHSD technology.
In 2016 the first integrated Harrington Seed Destructor was tested on Australian soil- with great success, where up to 99% of weed seeds were pulvarised until no longer viable.
Two Hydraulically driven mills were retrofitted onto the rear of a harvester. This has since been further developed to a mechanical direct drive system.
Whether you have a horizontal iHSD impact mill or are looking to get into this technology with the newly-released vertical configuration, you can rest assured that the kill rate of both configurations has been independently proven to be 98 per cent for annual ryegrass.
Dr Michael Walsh, Director Weed Research, Faculty of Science, The University of Sydney has been testing the efficacy of impact mills on weed seeds since the early days of development of the Harrington Seed Destructors.
“The vertical configuration of the iHSD mills changes the direction of the chaff flow into and out of the mills and this can affect the processing of the chaff and potentially the efficacy of weed seed destruction,” he says.
“Having previously shown that the horizontal iHSD impact mill can achieve at least 98 per cent weed seed kill, we were keen to repeat the test for the vertical mill configuration.”
During the 2018 harvest, a wheat crop at Broomehill was used to test the vertical mill. Twelve 20 m strips were marked out in the wheat crop where there was no annual ryegrass present. These plots were used to test the efficacy of the vertical mill at three different harvester speeds – 4, 6 and 8 km/hr.
“The result of this testing was a weed seed kill rate of at least 98 per cent for the vertical iHSD impact mill, regardless of the harvester operating speed of 4, 6 or 8 km/hr,” says Dr Walsh. “This level of weed seed destruction is equivalent to that of the horizontally mounted mills that we have tested previously.”
