Harrington Seed Destructors are widely used in Australia.

Destructor’s weed escapes still fail to germinate

Microscopic abrasions allow microbes to infect embryonic weeds

Many weed seeds that appear undamaged after passing through a Harrington Seed Destructor still fail to germinate, say researchers at the University of Illinois. Developed and widely used in Australia, the HSD is mounted on the back of a combine and crushes weed seeds to prevent them from germinating. A University of Illinois release says

Losing the war on weeds

Tammy Jones has been doing the math on where herbicide resistance is taking Manitoba farmers and the numbers are grim
