This project will take a multi-factorial approach to the identification of edaphic factors and their collinearity for the prediction of foliar disease caused by the fungus, Phoma ligulicola in Tasmanian pyrethrum crops. This will allow implementation of a decision support system whereby disease management options may be weighed against site specific risk. Alternative management strategies to the current fungicide based system for control will also be assessed for their efficacy and role in mitigating site risk. The effect of cultural control methods such as cultivar mixtures and host resistance will be modelled on the spatio-temporal characteristics of the epidemic and compared to these in naturally occurring epidemics at specific sites.

该项目将采取多因子的方法来识别土壤因子及其共线性，以预测塔斯马尼亚除虫菊作物中由真菌（Phoma ligulicola）引起的叶面病害。 这将允许实施一个决策支持系统，从而可以权衡疾病管理方案与现场特定风险。 还将评估目前以杀真菌剂为基础的控制系统的替代管理战略在减轻现场风险方面的功效和作用。 将根据流行病的时空特征模拟栽培控制方法（如品种混合物和宿主抗性）的效果，并将其与特定地点自然发生的流行病进行比较。
