Beyond the Bale : February 2010
February 2010 BEYOND THE BALE The LiceSense manual and calendar LiceSense AWI is helping growers make sense of the increasing problem of lice infestations with a new extension program known as LiceSense. With the spread of resistance to some backliners and the removal of diazinon as a sheep dipping agent, AWI is offering support to growers. After discussions with various state farm organisations, AWI is assisting with the cost of training growers, farm supply merchandisers and woolbrokers in the full range of options available for controlling lice, including the new test that uses shearing combs and cutters. Training can also be provided via farmer groups, through state departments of primary industries or in-store events. As part of the LiceSense program, staff at farm- supply outlets can be trained in problem solving, and to tailor information according to a woolgrower's individual situation. The chemical treatment of stock is just one of the suite of solutions a reseller can supply. The LiceSense program includes a handy guide for woolgrowers on managing sheep lice. As well as useful information, it contains a LiceSense cartoon calendar, illustrated by South Australian shearer Jed Dunstan. More information: www.wool.com; for a copy of the manual, call the AWI Helpline, 1800 070 099 Flip to the back for Jed Dunstan's 2010 calendar Jed Dunstan is a year-round shearer and established cartoonist from the Mid North of South Australia. Jed also works on the family farm at Ngapala, where he can be contacted on (08) 8581 1505 and email@example.com Has the efficacy of lice control diminished now that diazinon has been suspended? Recently a sheep farmer contacted us unhappy with his cur- rent level of lice control. Interestingly, he commented that his control seemed to be much better 20 years ago when he was plunge dipping and went on to lament the suspen- sion of diazinon for dipping or jetting sheep. While some may see this as viewing the past through rose tinted glasses, plunge dipping to control lice is still regard- ed by experts as the "gold standard" in lice control. The introduction in the early 1980's of pour-on treatments and their wide spread adoption came about primarily due to their ease of use and the time and labour savings they brought. Sadly, in some ways, pour-on treatments have become a victim of their popularity. In many cases familiarity has bred contempt and the attention to proper application methods has slipped causing control breakdowns. Add to this a fail- ure to rotate away from a product that is working and you have the potential for resistance developing. Our advice to this farmer was that plunge dipping was still a very viable control option and one of the best methods of ensuring correct application. We were able to inform him that Coopers Assassin (containing Temephos) was an ideal replacement for diazinon when used as a dip. We discussed with him the status of his on farm dip and de- cided that given the current condition of his equipment that it was more economical at this stage to recommend a lo- cal dipping contractor to treat his mob. Over the next 12 months he is planning to recommission his old dip and to return to dipping for a couple of years to give the pour-on backliners a break.
