NSW DPI state worm control co-ordinator Stephen Love said above-average summer rain will make worm control very challenging, especially on the North Coast.

C[pounds sterling]Although the weather system isn't as strong as last year, two La Ninas back to back combined with worms carried over from last autumn have increased the worm risk.
C[pounds sterling]In wetter areas, we recommend producers monitor sheep every four weeks for the next few months Co they can do this by monitoring sentinel mobs, those similar to other mobs in age, class, drenching and paddock history.C[yen] WormTest kits with full WEC instructions are available from NSW DPI offices.
To get the best value for money, Dr Love advised producers to use the most effective drenches.
