Determining the economic impact of Native Budworm (Helicoverpa punctigera) in cereal crops in the Western Region

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.

Geometric uniformity improves yield of canola and lupin

To determine if spacing lupin (Lupinus angustifolius L) and canola (Brassica napus) plants in more uniform geometric patterns can improve yield of these species in the Northern Agricultural Region of Western Australia.
