Pea seed-borne mosaic virus (PSbMV) causes a serious disease of field pea crops. This project (i) established the extent of PSbMV infection in commercial crops and seed stocks, (ii) increased understanding of PSbMV aphid vector relationships and epidemiology, (Iii) Improved control measures, and (iv) developed a forecasting model to predict epidemics and optimise virus management decisions. PSbMV infection was widespread, single gene resistance broken, seed fractionation for control demonstrated, wind-mediated contact transmission shown and virus manipulation of aphid behaviour found. Glasshouse experiments and six years of field data revealed the key epidemic drivers used to develop the predictive model.
