TAS Country : September 22nd 2011
8 Tasmanian Country Friday, September 23, 2011 Your Say HARVEY GEE: Our hawthorn hedges could be under threat. Picture: ROSS MARSDEN Time to protect heritage hedge I AM writing in regard to fire blight extinction of heritage-listed hawthorn hedges -- the crataegus species of the rosaceae, or apple, family. As owner of a farm comprising some 30km of such hedging, I draw at- tention to the threatened extinction of a district icon, from Hagley to Mole Creek and the lower White Hills area. A major feature of fire blight spread in England has been the movement among hawthorn, or crataegus, hedges along roads and railways. These hundreds of kilometres of attractive and valuable shelter are the perfect host for the disease and face extinc- tion themselves if fire blight establishes in Tas- mania. They were planted by the early settlers in Tas- mania, before fencing wire, from the 1820s on, and fire blight is their only serious threat. They have withstood the test of time.

Negative interactions between Oster tagia oster tagi and Cooperia oncophora in calves. Vet Parasitol 1984; 15: 135--150. From over 43,000 dung tests conducted across Australia, we know the worms that count in your area are Cooperia spp. and Ostertagia ostertagi1. In fact, they make up to 91%† of the worm infestation in Tasmania. Individually these worms harm your cattle s performance. But when they join forces they can seriously damage your operation, with studies showing that Cooperia increases the effects of Ostertagia, which can result in reduced weight gain and ill-thrift.2 Are you using the right drench?
