Native budworm actively feeding on cereals has not been an issue for growers or industry in the past, and considering the recent detections, growers and western region industry networks have voiced that they would like support on this issue, especially regarding sampling techniques and spray thresholds. To achieve this, we investigated this new behavioural trend and the population numbers required to cause economic yield losses to determine if and when management is required in non-traditional cereal hosts.

Through pheromone-based moth trapping, crop inspections, glasshouse trials and a field cage trial, we investigated the behaviour of H. punctigera moths and larvae on, and potential economic damage to, wheat in the northern grainbelt of Western Australia.

To answer the quesitons:

• Does in-furrow application of fungicide using liquid banding improve control of Rhizoctonia solani compared to the untreated control or seed treatment?
• Does in-furrow application of fungicide using liquid banding improve control of Rhizoctonia solani compared to coating of granular fertiliser?
• Does an integrated approach incorporating cultivation, seed treatment and in-furrow fungicide application improve control of Rhizoctonia solani compared to the untreated control and all other individual treatments?

Individual objectives specific to the trial were:
- Monitor the effectiveness of flutriafol in furrow for early disease control in wheat.
- To evaluate whether newer germplasm or new fungicide chemistry allows a reduction in the number of fungicide applications whilst increasing profitability (note: reducing the number of fungicides is seen as a key measure for slowing down resistance development in cropping systems).
