DownloadRice growers in New South Wales face growing pest management challenges. Older insecticides are becoming less effective, and some are no longer available. This project explored practical ways to manage pests while maintaining rice production.
The research focused on major rice pests in the Riverina. These included native armyworms, rice bloodworms and rice snails. The project also investigated whether Russian wheat aphid could damage rice crops.
Researchers improved understanding of how pests affect crop yields. They identified natural enemies that help keep armyworm numbers low. The project also developed better treatment thresholds to support pest management decisions.
The study generated data on selective insecticides. These products can control pests while reducing harm to beneficial insects. They can also help lower the risk of pesticide resistance. Researchers found resistance in some bloodworm populations and tested alternative treatment options.
The project confirmed that rice is not a suitable host for Russian wheat aphid. This result removes a key concern for growers and reduces the need for unnecessary pesticide use.
The findings show that effective pest management requires a mix of biological control, selective pesticides and resistance management. Ongoing research will remain important. Together, these approaches can protect yields, reduce pesticide use and support a more sustainable future for rice production in NSW.
