Summary
Spraying the growth regulator mefluidide onto potato foliage at 500 or 1000 g/ha on two dates in July after tubers had been initiated did not affect the number, size and yield of tubers or the extent of injuries after mechanical harvesting. The skin of some tubers from sprayed plants was brown and this was more common from plants sprayed on 15 July than on those sprayed two weeks earlier. Spraying at 1000 g/ha decreased the severity of black scurf but increased gangrene.
