Abstract
The spatial dynamics of many soil-borne, fungal, plant pathogens, depend on the ability of fungi to grow through a heterogeneous framework of cracks, pores and aggregates to initiate infection and to spread from host to host. This project is designed to test and quantify the effects of local changes (of the order of 0.1 - 10cm) in selected soil physical factors, that influence soil structural heterogeneity, on the local spread of fungal plant pathogens in soil. Simple mechanistic models for the effect of short-scale heterogeneity in soil physical properties on the growth and spread of pathogenic fungi in the rhizosphere and surrounding soil will be developed and tested. Two host-pathogen systems will be used, Gaeumannomyces graminis on wheat and Rhizoctonia solani on radish or lettuce.
