Detection and control of mild strains of potato leaf roll virus

The role of plant pathology research in the Canadian potato industry

“…An understanding of the ecology of the vector and sources of inoculum in western (Wright et al 1967) and eastern Canada (Bagnall 1988) has helped in controlling the disease by appropriately timed spraying of aphicides and vine-killing. The incidence of PVY recently has become increasingly frequent in both the Canadian and American potato industries.…”

“…Enormous progress was made in the control of tuber-borne diseases by advancement in stem cutting and tissue culture technology (Cole & Wright 1967). Not planting seed tubers for one generation breaks the continuum of passing on pathogens from one field generation to the next.…”
