TAS Country : August 19th 2010
24 Tasmanian Country Friday, August 20, 2010 2041046-100820 TO VIEW OUR BIRD NETTING AND COMPLETE RANGE OF PRODUCTS: www.pestawayaust.com.au TO ORDER A FREE CATALOGUE: Ph (02) 6493 5840 Fax: (02) 6493 5841 Email: email@example.com Pest-Away covers crops and banishes pesky birds An investment in bird proofing can mean better yields and bigger profits for farmers PEST-Away Australia specialises in supplying bird proofing products such as bird netting for protecting crops and proof- ing buildings. The company also sup- plies bird scare devices for applications that cannot be bird proofed. ''If you wish to improve your crop yield or proof your building from birds, Pest-Away Australia can help,'' company spokes- man Trevor McAndrew said. ''When it comes to crops, Pest-Away Australia is an agent for one of the sup- pliers of the best quality throwover style anti-bird netting in Australia. ''We can supply netting in either custom cut lengths or in commercial bulk quantities. ''We also specialise in 'urban netting' which uses a particular style of netting specifically design for proofing buildings. ''Or perhaps you need stainless steel bird spikes that can prevent all kinds of birds from perching, roosting or even nesting. ''If you cannot consider bird proofing then perhaps our bird scare products can help --- 'Scarey Man' automatic scarecrows or perhaps a lifelike 'Prowler Owl'. ''Back in 1999, the busi- ness identified a need for a diversified approach to minimising problems cau- sed by pest birds. ''Before deciding on a product range, the original owners travelled to many regions of rural Australia and discussed pest bird problems with grape growers, grain farmers, fruit and berry farmers, olive farmers and aquacul- turists. ''Particularly valuable background information was gathered at rural field days and wine industry exhibitions throughout eastern Australia, and from state departments of agriculture. ''In recent years, how- ever, the focus is changing, with just as much demand generated from the urban and industrial sectors.'' Trevor and Kumi McAndrew have experi- ence in broadacre farming, aviation and international bird management tech- niques. And their company uses consultants in the agricul- ture, aviation and con- struction industries. For more information go to www.pestawayaust.co- m.au or phone (02) 6493 5840. Advertising feature Pest and weed control Eternal vigilance the price of THREAT: Participants at a serrated tussock field day learn how to identify and deal with the noxious weed. SERRATED tussock is probably Tas- mania's most noxious weed. It poses a significant threat to sensitive native grasslands, conservation areas and the grazing industry. As well as being an environmental threat, estimates indicate a potential annual loss of millions of dollars to the grazing industries should it spread to all predicted available habitats. Unlike Victoria and New South Wales, Tasmania still has the ability to eliminate the threat serrated tussock poses. Serrated tussock is one of the 20 weeds of national significance due to its highly invasive nature, its negative impacts on agricultural production and its threat to biodiversity, particularly native grass. Why is it a weed? Serrated tussock is an aggressive, invasive perennial grass with the ability to survive under dry conditions. It is a weed of grazing lands with poor soil fertility and low rainfall. In these areas, competing vegetation is limited and the benefits of control are marginal. Serrated tussock is unpalatable and rarely eaten by stock. It has no nutritional value and stock given only access to serrated tussock will quickly loose condition. Worse still, due to its very low digestibility, stock forced to eat serrated tussock will starve to death despite having a full stomach. Dense infestations can completely dominate pasture. It is also a serious environmental weed that invades dry coastal vegetation, grasslands and open woodlands. Serrated tussock is a Declared Weed in Tasmania and a Weed of National Significance. How does it spread? Serrated tussock is mainly spread by wind-borne seed. Mature plants can produce more than 140,000 seeds per plant per year, and the very light seeds can be blown up to 20km. Seeds can also be spread by humans and animals. They can attach to fleeces or lodge in mud on the hooves of livestock. They can attach to cultivating and slashing implements, to tyres and even to firewood. Buried seeds can remain viable for up to 15 years, so reducing soil disturbance is a good management practice. Serrated tussock seedlings are usually out competed by other plants, but can quickly become established when other vegetation is removed, such as through overgrazing or drought conditions. What does it look like? Serrated tussock is a perennial, tussock forming grass with a deep, fibrous root system, similar in general appearance to several of our native tussocks. Young plants are erect and densely tufted with tightly in-rolled leaves; the leaves are bright green and the leaf sheaths at the base are pale, more slender and closely packed than in the native tussocks. As the plant grows to maturity, the later leaves become longer, the tips turning to brownish green or, in winter, a bleached straw colour. Leaves at all growth stages feel rough or serrated if the finger and thumb are drawn down the blade. By the time the tussock is at the flowering stage the leaves are long and drooping. How can it be controlled? For long-term control, vigorous improved pastures must be established to compete with serrated tussock to help prevent re-invasion. Ploughing or spraying alone without pasture establishment is not effective because serrated tussock will regenerate from seed reserves in the soil. All control programs should aim at reducing the amount of serrated tussock available to germinate on your property. Hilltops should be a priority for control works as they are an important source of wind borne seed spread to surrounding areas. The principles and methods of serrated tussock control are: Prevention Preventing the invasion of serrated tussock is the cheapest and most effective way of controlling it. Do not let serrated tussock establish beyond a scattered low density or else control measures become expensive and difficult. This means that each year every paddock must be searched for serrated tussock. Learn to identify serrated tussock, regularly check for it and act immediately to remove it. Place stock grazed on serrated tussock in a holding paddock to empty them out of faeces containing seed, before moving into a clean paddock. Buy certified seed and avoid purchasing hay or stock from contaminated areas. Establish tree belts or phalaris barriers along boundaries with infested properties to help reduce the amount of seed blowing into your property. Keep pastures vigorous and manage Serrated tussock targeted SERRATED tussock is found mainly in Tasmania's South East. It has been in the state since before the 1950s. Areas like South Arm, Droughty, Cambridge and Sorell have been the core area of ser- rated tussock for a number of years. It is also found on the East Coast and there are small populations on King Is and in the Midlands. There is active management of serrated tussock on the majority of sites in the state and some kind of management on all sites, said Department of Primary Indus- tries, Parks, Water and Environ- ment Southern Regional weed management officer Karen St- ewart. ''The main focus is to prevent further spread of the weed,'' Ms Stewart said. Intensive monitoring and sur- veillance of the weed has been undertaken by DPIPWE over re- cent years. Ms Stewart said the DPIPWE website had updated weed in- formation and has been re- vamped to make it more user friendly. ''If people think they have serrated tussock contact us and we will come out and check it out,'' she said. ''It is a difficult weed to identify but once you get your eye in for it you can identify it easily. ''The more people we can get aware of it, the more chance we can get outlying populations before they can get estab- lished.'' - Boom Spraying - Slashing - Mulching - Handgunning - Air Seeding - One Pass Cultivating CIRCULAR HEAD - BOAT HARBOUR Phillip Wilson - 0427 871 032 WYNYARD - DELORAINE & FORESTRY Phillip Costello - 0418 585 908 BOAT HARBOUR - SASSAFRAS Ben Chillcott - 0437 997 179 ALL OTHER ENQUIRIES - Richard Murrell - 0418 142 518 OFFICE 1800 041 184 FAX 6452 2350 www.beechworth.biz - Fertiliser - Lime - Urea - Dolomite - Seed - Row Crop 2025565-100820
