iHSD is installed neatly into a combine harvester, rear of the seives, and processes the chaff fraction of harvest waste.
Using patented technology, iHSD mills 'destruct' weed seeds without the use of chemicals or burning.
Superior Weed Management
iHSD is not genetically selective to herbicide resistant weeds, meaning, herbicide resistant weeds can be controlled effectively at harvest time.
'Destucting' resistant weed seeds makes conventional herbicide control more effective in following seasons.
No carting. No burning. No handling.
iHSD is a single-pass HWSC solution, it requires no additional labour compared to regular harvesting.
Persistent iHSD use depletes the soil seed bank and targets herbicide resistant weed populations, this results in fewer herbicide treatments.
Improved Soil Health
Processed chaff is returned to the soil as readily broken down organic residue, retaining moisture and promoting a healthy microbiology, with fewer organic supplement treatments.
Improved soil health and fewer weeds equals increased crop yeilds.

Destroy your competition!
iHSD - Integrated Harrington Seed Destructor is a revolution in Harvest Weed Seed Control, which is highly effective against herbicide resistant weed populations. Integrated at the rear of a combine harvester, iHSD kills weed seeds contained in harvest trash and returns inert organic matter to the field, all in a single pass without changing harvesting practices.
Harvest Weed Seed Control (HWSC) has become a pillar of no-till farming practice in Australian cropping operations and is gaining momentum quickly across the world. Farming practices that rely heavily on broadscale herbicides to control weeds has led to the emergence of genetic herbicide resistant weed populations.
In the fight against weeds take a zero tolerance stand: kill every weed at every opportunity and ensure a sustainable farming operation.
To win the war on weeds it makes sense to kill weeds at every opportunity and with every tool available. This will delay or possibly prevent genetic resistance manifesting to any particular control method. Common weed control variation is achieved by mixing and rotating chemicals, reducing row spacing to increase competition against weeds, and removing weed seeds at harvest time.
When iHSD is used as part of a holistic weed management strategy weeds are controlled effectively. Operational control, flexibility and opportunity is returned to the farmer. Herbicide treatements are more effective on sparsely populated weeds and multiple treatments may even be eliminated. Fertiliser supplements may be reduced as chaff is returned to the field and material is not removed or burned.
Developed, tested and refined from an idea conceived over 20 years ago by West Australian farmer/inventor Ray Harrington, the iHSD is the culmination of inspired efforts by Grains Research Development Corporation (GRDC), Australian Herbicide Resistance Initiative (AHRI), Agricultural Machinery Research & Design Centre at the University of South Australia (UniSA) and De Bruin Engineering Pty Ltd who are exclusively licensed to manufacture the patented HSD and iHSD technologies.
