If you do decide to worm egg count before you drench, also, if fluke is in your region, request a liver fluke test. Moisture conditions in some regions are becoming increasingly favourable for increases in Haemonchus burdens and fly populations—lice may also be a worry.

Patchy rains could lead to a risk of barber’s pole infections, especially in the south-east. Burdens of immature thin-necked intestinal worms have already caused production losses.

Monitor all stock, especially weaners grazing green pick. Larval pick-up now could lead to spikes in worm egg counts in 2–3 weeks.

It is still essential to WormTest sheep grazing patches of green pick.

Worm egg counts should be low coming into autumn to avoid worm burdens later in the year.

Merinos on perennial pastures are due for a second summer drench. Haemonchus and liver fluke infections are present on irrigated farms, and unprotected sheep may need a fly treatment.

Worm egg counts in some mobs are quite high despite poor seasonal conditions. Monitoring in individual mobs is essential for effective worm control.
