Some districts in NSW and Victoria are known to frequently develop Sclerotinia stem rot. The purpose of conducting the petal survey was to identify if there are significant differences in the level of petal infestation between districts where the disease develops frequently, compared with those districts where the disease develops once every few years. This information will indicate what influences disease development, background inoculum levels or environmental conditions, or both.

The aim of the experiment was to examine the effect of crown rot on yield in 12 bread wheats, one durum wheat and five barley varieties of differing tolerance levels in southern NSW (sNSW).

To better understand and quantify potential production losses incurred from foliar, crown and root diseases by developing response curves.

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?

To determine if mobile phone technology can be used to map and study snails in the field.

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.
