State Outlooks for February 2021

Flies and barber's pole worms are on the radar this month. Conduct a WormTest with larval culture to see just how big a problem barber's pole is on your property.

Our correspondents report that barber’s pole worms and scour worms are taking advantage of the mild and wet weather across the state. Requesting larval cultures while conducting a WormTest is highly recommended to get a clearer picture of the breakdown of worms.

 

Victoria

Producers should be monitoring all sheep regularly for worm burdens, as the number of sheep requiring drenching remains high. This is especially true for weaners, as they will have lower immunity to worms. Flystrike is also on the increase; think about how you can reduce populations before sheep are struck.

Conditions are right for both flies and barber’s pole worms. Test for worm burdens regularly, with an emphasis on taking the best possible samples. Follow up 10–14 days later to see what impact any drenches had, and to make sure you’re using an effective product.

 

Western Australia
>> full report

If sheep have been drenched effectively onto low-risk pastures or stubbles, the worm risk should be low. However, this will vary depending on rainfall and temperature — hot and dry weather should kill larvae on pasture. Either way, a WormTest will give a clearer picture.

Tasmania

Now is the time for a second ‘summer’ drench, and consideration should be given to a third if worm egg counts remain high, especially when seeing cooler temperatures and green pastures. Paul also has some advice for assessing lice risks to decide on a treatment.

 

South Australia
>> full report

Significant worm burdens have been seen, likely as a result of January’s rainfall. Regular monitoring is the only way to catch increasing burdens before production loss occurs. It’s also time to be thinking about preparing low-risk paddocks for weaners.
