An Australian farmer's invention, which destroys weed seeds during harvest, has the potential to reduce the need for herbicides in grain farming and is gaining interest from around the world.
The Harrington Seed Destructor (HSD) can be retro-fitted into modern grain harvesters and, with cage mill technology adapted from the mining industry, pulverises weed seeds to the point where they are no longer viable.
According to the Grains Research and Development Corporation (GRDC), weeds cost Australian grain farmers around $3.5 billion a year, and there is an increasing problem with weeds that have built up a resistance to commonly used herbicides.
