Destroy Weed Seeds While Harvesting - Introducing the iHSD

18 March 2016

Destroy weed seeds while harvesting!

McIntosh & Son is pleased to introduce you to the exciting and revolutionary Integrated Harrington Seed Destructor (iHSD). The culmination of 20 years of research and development, the iHSD controls weed seeds by way of mechanical impact trauma to the seed. The iHSD 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 can destroy 93-99% of the weed seeds that enter them.

The iHSD has major advantages over many traditional weed control methods. iHSD is a modular package that generally requires only minor adjustments to existing harvesting operations:

Harvest time weed seed control prevent weed seeds entering the seed bank

  • Fewer weeds emerge in following seasons, enabling chemical control to be more targeted and efficient

Mechanical control is non-selective toward herbicide resistant seeds

  • Lessens critical build up of herbicide resistant weed strains
  • This will delay development, if not eliminate herbicide resistant weed strains
  • Fewer herbicide resistant weeds emerge and can be targeted with highly effective control measures, generally too expensive to consider at broad scale

Organic matter and residue is returned to the soil

  • Promoting a healthier, more stable soil profile
  • Less organic supplements are required

One pass processing at harvest

  • No chaff carts
  • No wind rows

No burning

  • Reduced fire risk to property and the environment
  • No smoke pollution created
  • Reduced seasonal fuel loads (i.e. stockpiling over fire ban season)
  • Retained soil organics and corresponding soil nutrient holding capacity

The 2016 production of the iHSD has been allocated. 2017 production is being planned now. Contact McIntosh & Son to register your interest, or place an order to avoid disappointment.
