“To win the war you must win the battles. Harvest weed seed control is an important battle” – Ray Harrington, WA grower & inventor of the Harrington Seed Destructor
Our harvest weed seed control special edition enews was included in a recent GRDC Weed Alerts email (read past editions here). We felt that it’s a handy resource that was worth including on our Bulletin Board. Read on for more info and our “which HWSC tool is right for you” checklist!
WeedSmart enews #8
Welcome to our harvest weed seed control (HWSC) special edition (we like to get in nice and early).
We’ve included links to further info on the five main HWSC tools, plus a quick little checklist to work out which tool is right for you.
Which HWSC tool is right for you?
Follow the links below for more info on the HWSC tools relevant to your farming operation:
- Do you have sheep? Chaff cart / grazing dumps
- Are you a CTF grower? Chaff deck
- Are you a low cost, low rainfall grower? Windrow burning or chaff cart
- Are you hell bent on residue retention (are you a stubble hugger?)? HSD
- Are you CTF with a disc seeder? Chaff line / windrow rotting (early stages – stay tuned!)
- Do you have a market for straw near your farm? Bale Direct
Narrow windrow burning
By mounting a chute to your grain harvester, all of the exiting chaff and straw residues are concentrated into a narrow windrow about 500-600mm wide which is later burnt. There’s a 6 step intro vid, chute CAD drawings, plus tonnes of other handy resources over at the website.
Chaff carts are towed behind harvesters to collect the chaff fraction as it exits. The dumps are later burnt or grazed. Super quick video, handy financial factsheets and more are available for you here.
Harrington Seed Destructor (HSD)
A unique system developed by the awesome Ray Harrington that processes the chaff fraction to destroy any weeds before returning the material to the paddock. There is no need for any post-harvest operations and all harvest residues are retained (win/win!). More info? Here you go.
The Shields family in WA developed the Bale Direct System. The large square baler is attached directly to the harvester and constructs bales from the chaff and straw residues. For more info plus resources click here.
Funnel seed onto tramlines
In controlled traffic farming systems, weeds are funnelled onto an inhospitable environment – compacted by soil and run over by machinery (weeds deserve it). Find out more
