Australia's resource for control of worms, flies and lice in sheep,
and worms in goats

From the Editor

Do parasites take a break during a drought? While they are quieter, don't be complacent. Pastures still hold larvae that developed over previous months. Lice introduction risk could be higher with more sheep movements. Flies will still be attracted by urine stain and dag.

LiceBoss training is now online. Get a handle on lice control. Follow your preferred learning method: structured reading or questions and answers. >>LiceBoss Online Learning

Strategic versus tactical drenching

from the WormBoss web site

Drenches are useful not just when sheep are suffering from worms, but also as a way to strategically benefit the whole flock, not just the treated sheep. >> Read more.

Dogs sniff out flystrike-resistant sheep

from the DAWFA Mt Barker Breech Strike Resistance Newsletter Issue 6

Sniffer dogs are being used to identify sheep that are inherently more resistant to flystrike, regardless of how plain or wrinkly they are. This will be used to identify how resistant sheep differ from susceptible sheep. >> Read more.

Long wool lice treatments—when are they justified?

by Deb Maxwell, ParaBoss Operations Manager

If lice have been introduced to your previously lice-free flock, should you immediately treat, or simply wait until next shearing? The Long Wool Tool at LiceBoss.com.au provides a simple way to help you answer this question. >> Read more.

State outlooks for November 2014

New South Wales
>> full report

Seasonal conditions vary from drought to patchy.  Despite many regions being dry, some high barber's pole WECs continue to turn up.  Where there has been useful rainfalls, be wary of sheep congregating on short green pick—barber's pole can explode under such conditions.

Many districts are dry.  This can be good news —it makes it easier to prepare low worm paddocks for the future; or it can be bad news —drenching at these times really selects for drench resistance.  Don't drench without a WEC!  Avoid long acting drenches at this time.  It's better to use highly effective multi-active constituent products.

Queensland
>> full report

A strain of Barber's Pole worm highly resistant to Monepantel (the active in Zolvix®) has been isolated from a property in SW Queensland.  While Monepantel is still theoretically effective (>95%), resistant worms, particularly Barbers pole, have demonstrated a propensity to rapidly increase. 

It is a warning to be very careful when choosing an appropriate drench and the need to regularly do WECs and Resistance Tests.

Summer drenching is the main activity where necessary.  The key decisions—which sheep, when and what with.

Get it right to prevent losses and increase resistance!

Tasmania
>> full report

Worm activity is largely reflecting a mixed bag of seasonal conditions.  At this time of the year and in such conditions, it is critical to get management right and based on fact—not guesses.

Choosing an appropriate fly treatment will also be important where it is needed—be mindful of ESI's and WHS before treatment.
