Environmental variables influencing the incidence of Pierce’s disease
M.J. Costello, S.J. Steinmaus, C.J. Boisseranc
Pierce’s disease (PD) of cultivated grape, Vitis vinifera, caused by the bacterium Xylella fastidiosa (Xf) and transmitted by xylem-feeding insects, can lead to vine decline and death. Infection and expression of PD among or within vineyards vary, depending on known environmental variables, such as climate and Xf vegetative reservoirs, as well as some which are little studied with respect to PD, such as soil, water and nutrition.
