iHSD tackles weeds at source by pulverising seeds in the chaff at harvest

Australian grain growers tackle weeds at source, with a combine harvester add-on that destroys the weed seeds.

The American Society of Agricultural and Biological Engineers (ASABE) thinks it is a good idea.

They have included the Integrated Harrington Seed Destructor (the iHSD) in their 2017 AE50 awards for the most innovative designs in engineering products or systems for the food and agriculture industries.
