Dispelling a myth: Seed Coat
Goldstrike® vs untreated seed The trial confirmed that Goldstrike® treated seed achieved a higher actual plant establishment, with less seeds per kilogram planted, than untreated seed. This demonstrated the superior technology encapsulated in the Goldstrike® process. Lucerne seed with 95% germination sown at 10kg/ ha sown under irrigation.

Benefits of a successful nodulation.
Assists with establishment vigour and plant development, essential to the overall productivity of the legume crop as a whole and more nitrogen is fixed for the next crop Pasture Genetics has had an extensive goal to extend the lifespan of the live rhizobia on Goldstrike® seed treated products.
This challenge has taken the current industry standards to further than most companies have been able to achieve within Australia. The extension of the lifespan enables the Australian farmers to take advantage of a wider window of opportunity for planting Goldstrike® products. This treatment exposes the limitations to standard farmer applied inoculation systems where, in most cases, the rhizobia die within the first 48 hours.
Pasture Genetics understands the limitations that farmers and retailers have and have seen this project as one of the most important issues for Australian Farmers.
Pasture legumes that are pre-inoculated need to be able to handle long timelines between application of rhizobia to being stored and transported, then to wait for the most accurate seeding window. These long time lines end up affecting some of the current treated lines within our industry.
These products need to be applied at separate stages of the treatment process very accurately. The rhizobia themselves can be severely affected by certain chemicals, fungicides, heat and rapid or aggressive movement at the treatment stage.
The recommended standard number of viable rhizobia per seed at time of sowing (according to ALIRU) is 1000 for large and medium sized seeds, and 500 for small seeds such as white clover.
This should achieve adequate nodulation under all conditions, though some constraints such as drought, highly acidic or sodic soils, etc., may suppress nodulation.
However, the recommended standard does represent realistic and attainable numbers of rhizobia that should ensure nodulation under most conditions of establishment and plant growth.
Goldstrike Longlife® achievement details.
Pasture Genetics is very proud that after many years of research we have achieved 1000 viable rhizobia per seed on stored lucerne, 12 months post treatment date.
And 1000 viable rhizobia per seed on stored medic and sub clover, 6 months post treatment date.
In 2009, under normal storage conditions this has been achieved by Pasture Genetics, and independently verified using third party testing (New Edge Microbials and SARDI).
This ground breaking achievement now gives Australian Agriculture extra confidence in Goldstrike® products.
The longlife rhizobia now gives a wider opportunity for the planting window. Seed is a living product and requires to be handled with care. Rhizobial treated products need to be stored in cool dry conditions out of direct sunlight.
Goldstrike® - Farmer Feedback
A paddock which contained two types of inoculated seed of the same variety demonstrated the superiority of the Gold Strike treatment to Craig Bittner, at his Curramulka property,on the Yorke Peninsula in South Australia. Mr Bittner sowed 38 hectares of Bartolo bladder clover in late June this year with five hectares of the crop treated with inoculant as part of the Gold Strike package and the remainder treated with an inoculant from another source. The gold coloured Gold Strike seed is available exclusively from Seed Distributors. It was planted on the same day as the purple coloured seed from the alternative company and performed much better from the beginning. “Full marks to the Gold Strike ,” Mr Bittner said. “It was a lot more vigorous.
The other stuff barely came up, and when it did it just sat there. The difference was daylight and darkness.” He said he had always been a bit sceptical about inoculant treatments but had changed his mind with the performance of the Gold Strike - treated seed in the paddock. The plants in the Gold Strike area also had much better root systems and were showing nitrogen nodules from quite early in the season. Mr Bittner said the germination from the purple seed was a quarter to a third of the other seed and provided very little plant density. “You could see the line between it and the Gold Strike area for weeks and months,” he said. “At one stage theGoldstrike was four to six inches high and the other was still at ground level.”
He said the key to a good pasture paddock was to get it established and thick, which is what occurred in the Goldstrike area. The Bartolo bladder clover was trialled on the property because of its ability to handle a range of pH soil types. Mr Bittner said the farm ranged from ridges and sandy hills to heavy flats, so a variety that would perform under those conditions would be handy. He was also looking for herbicide options in the rotation and sprayed the Bartolo paddock with Broadstrike early and a mix of MCPA and Affinity later in the season. The later herbicide option did check the crop going into spring, although the Gold Strike treated section responded earlier and much better than the other area. Due to the late plant and the poor result in part of the paddock the Bartolo was not utilised to its full potential. Mr Bittner said in the future he might look at planting the Bartolo earlier in the season and using it as a grazing option.
