Look out for other invertebrate pests

Redlegged Earth Mites and Blue Oat Mites hatch from summer diapause eggs in autumn, triggered by colder weather and significant rainfall. Swarms of mites can attack delicate crop seedlings and emerging pasture plants. Earth mites attack pastures and a variety of crops such as cereals, oilseeds, lupins and lucerne, as well as a variety of weeds. We have received reports of redlegged earth mites and blue oat mites in some cooler regions of Victoria, and they are likely to become widespread in the near future.

Cutworms can be a problem to a variety of germinating crops. Prolonged autumn green feed in areas can allow grubs to develop to a large size by the time crops start emerging. Check crops, especially pulses and pasture legumes, by inspecting the base of plants; damage is often patchy.

Slugs are stimulated out of their summer aestivation following autumn rains, generally in paddocks were they have previously been a problem. All seedling crops and pastures may be attacked, however canola is particularly susceptible. Slug numbers can be monitored by placing tiles or flowerpots on the soil surface and counting the number under them after a few days.
