Field trials of the Harrington Seed Destructor (HSD) in South Australia, New South Wales and Victoria have shown the weed-management device is as effective at managing annual ryegrass in the east as it is in the west... Results from the counts show the HSD had the same affect on annual ryegrass populations as in WA trials in 2010... The HSD was invented by WA farmer Ray Harrington as an alternative to windrow burning and chaff carts...

Weed seed destructor on course for commercial launch One of the most anticipated technologies in Australian agriculture - the Harrington Seed Destructor - has progressed to commercial production... The first unit is now in the advanced planning stage, and de Bruin's in-house engineers have already made a number of improvements based on feedback from growers and researchers who observed and inspected the HSD during trials conducted during last harvest... Trials, demonstrations and evaluations over the past couple of years have been overseen by AHRI researcher Dr Michael Walsh, who is based at the University of WA. Dr Walsh is continuing to assess the efficacy of the unit in reducing weed emergence and he will also be involved in working with grain grower groups across Australia to train potential users of the HSD. Dr Walsh's research over the past five years has shown that during a grain crop harvest a significant proportion of the seed produced by weed populations (between 73-99% depending on the species) is collected by harvesters and then redistributed back across the field...

Seed Destructor on course for commercial production The Harrington Seed Destructor is edging closer towards commercial production, offering an additional strategy in the grains industry's battle against herbicide resistance in weeds... The trials and evaluations are being overseen by Australian Herbicide Resistance Initiative (AHRI) researcher, Dr Michael Walsh, who says the trial sites will be revisited as soon as the break in the season occurs to assess the efficacy of the unit in reducing annual ryegrass emergence. ".. Dr Walsh said the trials and demonstrations in the southern cropping region during December involved 15 sites over 16 days and a travelling distance of 4000 kilometres during that time. "..

The members, including an agronomist, heard first-hand about the research and developments that have been taking place in the fight against herbicide resistance... Local growers need to look at the experiences of other growers from further afield, including those internationally, in order to employ the best herbicide and mechanical strategies possible to manage their own herbicide resistance problems... Learn how herbicide resistance is being dealt with internationally and in other parts of Western Australia (WA) and understand how growers can adopt relevant strategies into their farming systems...

The comparison of chaff carts, windrow burning and HSD systems at 12 WA wheat belt sites during the 2010 harvest found that all three systems resulted in 50% reductions in the autumn emergence of annual ryegrass populations... To evaluate and demonstrate the HSD system across a range of crop production environments, the HSD and accompanying header were taken on the road across the WA wheat-belt during the 2010 harvest... To demonstrate the HSD system, local crop producers were invited along to each site where they were provided a description of the HSD system and its efficacy in previous research trials...

Destructor technology ready to roll in Hyden.. Losing valuable time monitoring fires for days on end has been a major factor prompting North Hyden brothers Paul and Colin Green to switch from a chaff cart system to the Harrington Seed Destructor (HSD) for weed seed removal at harvest... "The risk of fire in unwanted places is just too great to continue with this form of weed control and using labour to watch chaff fires for such a long period is a luxury," Paul says...

Peter Sadler says the best features of the Harrington Seed Destructor (HSD) include: the ability to mechanically deal with ryegrass; the capacity to retain organic matter and keep nutrients rather than burn and destroy them; and being able to complete other jobs instead of windrow burning... "Chaff carts are OK, but you're burning nutrient, so when this HSD came up and we did some research, we decided to buy it," Peter says... "The previous model was belt driven and we believe they were a bit of a pain."..

Three versions of the Harrington Seed Destructor (HSD) underwent extensive tests in Western Australia during harvest 2010-11 to improve the machine's performance in crushing weed seeds... The size of the transfer duct has been reduced to make the material flow faster towards the mill, which Dr Saunders says should reduce the chance of blockages... Michael Walsh hopes to trial the HSD in Queensland, NSW, Victoria and SA during harvest 2011 to give growers outside WA an opportunity to see the device working in the paddock...

Losing valuable time monitoring fires for days on end has been a major factor prompting North Hyden brothers Paul and Colin Green to switch from a chaff cart system to the Harrington Seed Destructor (HSD) for weed seed removal at harvest... "The risk of fire in unwanted places is just too great to continue with this form of weed control and using labour to watch chaff fires for such a long period is a luxury," Paul says... Paul says he expects the machine will destroy a similar number of weed seeds to the chaff cart and burning system, but with the extra benefits of: not having to deal with chaff dumps; better use of labour; and retaining organic matter in the paddock, rather than burning it...
