Abstract

Field pests

Damage from invertebrate pests is generally not a major factor for oat crops, however there is a zero tolerance to live pests in export hay.

Significant damage can occur if pest populations build up. Planning rotations to minimise pest carryover, timely sowing, adequate crop nutrition, and good control of weed and root diseases will assist in reducing the likelihood of crop damage by insect pests. Check crops regularly throughout their growth for field insects.

• Control redlegged earth mite and lucerne flea during the seedling stage if necessary.

• Aphids should be checked for and controlled from flag leaf stage and later in crops considered to be high yielding.

• Aphids can also transmit barley yellow dwarf virus (BYDV). If growing susceptible varieties in areas with moderate to high BYDV risk, consider using insecticide seed treatments.

• Unnecessary spray applications have been linked to resistance developing in non-target pests, such as redlegged earth mite.

Correct identification of the pests is critical for their successful management.
