TAS Country : February 9th 2012
Friday, February 10, 2012 Tasmanian Country 19 Special Feature Tillage and planting Drought hardy perennial SOWING SUCCESS: Seventh generation Fosters, Emily and Angus, in a stand of Fosterville Phalaris at Ross. FOSTERVILLE Phalaris is a drought resistant, long- lived perennial grass which is well adapted for the drier areas of Tas- mania. It also has good toler- ance to waterlogging and grass grubs and is best suited to heavier soils. Uplands Cocksfoot is likewise very drought tol- erant and tolerant of grass grubs but is best suited to sandy soils. While both have been selected or bred for the Tasmanian environment to withstand both dry and cold conditions, in a practi- cal sense many paddocks have different soil types. These range from sandy dry banks to heavy winter waterlogged gullies. As both grass varieties are winter active and sum- mer dormant, they are slow to establish and with similar sowing rates (3-5kg/ha alone or 2kg/ha each in a mix) they com- bine well to give a very long-lived perennial pas- ture for the drier grazing areas. This is especially so in the variable climate we seem to be experiencing in Tasmania. Fosterville is an ecotype of Australian Phalaris and originally selected on Fo- sterville property at Ross, owned by the Foster fam- ily, now run by Simon and Penny Foster. Simon's father Henry started sowing phalaris in the 1960s when it wasn't common practice in the district, sourcing his seed from Victoria. Seed from this original paddock was direct har- vested to sow subsequent paddocks on the property. Livestock have been mostly set stocked on the property over the last 45 years with very little phalaris staggers occur- ring. Fosterville Phalaris was first identified as a distinct ecotype of Australian var- iety in the 1980s by Stuart Smith and Dr Jim Carpen- ter from the then Depart- ment of Agriculture. They noted the paddocks on the property were more productive and persistent than the current Aust- ralian variety. Coupled with this, seed retention was improved, giving better and more consistent yields which is a big problem in phalaris. As a result of this, good supplies of seed are avail- able. Seed of Fosterville Phalaris is marketed in Tasmania and interstate by Tasglobal Seeds. It fits in well with the company's philosophy of promoting Tasmanian- bred varieties for local con- ditions and matching plants to the environment. Fosterville Phalaris combines well with Up- lands Cocksfoot to give a true long-lived perennial pasture for dryland graz- ing.Herbicide resistance warning RESISTANCE to glyphos- ate herbicide has been dis- covered in another grass weed of grain crops inter- state. A population of Great Brome grass found in South Australia is the third grass species in 12 months to become resist- ant to glyphosate, best known as the active in- gredient in Roundup. The other two weeds are Barn- yard grass and Fleabane. Glyphosate resistance has long been documented in annual ryegrass popu- lations in Victoria and three other states. According to the Aust- ralian Glyphosate Sustain- ability Working Group chairman Chris Preston, the discovery was a ''wake- up call'' for all growers. Dr Preston said it indicated any weed might develop glyphosate resistance. ARRANGE A DEMONSTRATION TODAY!
