Fact sheet: Pests

This fact sheet explains how pests affect oat crops and why effective management is essential for export hay production.

Pest infestations can reduce yield, lower nutritional value and cause contamination. They can also damage plant structure, which reduces hay quality and market value. In some cases, pests contribute to higher moisture levels, increasing the risk of mould, which is a serious concern for export hay.

Common pests in oat crops include lucerne flea, blue oat mite, redlegged earth mite, aphids and mice. These pests can spread quickly and cause widespread damage if not managed early. Therefore, regular monitoring is important to detect problems and respond before infestations become severe.

The fact sheet outlines a range of pest control methods. These include chemical, biological and cultural approaches. Chemical control should only use products registered for oats, with guidance available through the Australian Pesticides and Veterinary Medicines Authority. It is also essential to follow label instructions, including application rates and withholding periods.

Export markets have strict limits on chemical residues. As a result, growers and exporters must meet maximum residue limits set by importing countries.

By combining monitoring with targeted control methods, producers can reduce pest risks, maintain hay quality and meet export requirements.
