Abstract:
Attempts were made to grow seed potatoes in the Gilboa mountains and central Golan Heights both at ca 500 m altitude. The activity of winged aphids was low between May and September, the period suitable for growing seed potatoes. Potato virus X (PVX) and potato virus Y (PVY) were rare. The highest incidence of potato leaf roll (PLRV) was 17% at Gilboa and 5% at Nov (central Golan). In both areas, spindle sprout was a severe problem in progeny tubers and it was associated with a purple top syndrome, probably caused by a mycoplasma, that appeared during growth. Activity of the probable vector, the leafhopper Hyalesthes obsoletus, ceases in the Golan after June. Delaying planting until the end of May or later reduced the incidence of purple top and spindle sprout to nil. Both were reduced by Temik treatment and by covering the plots with netting but not by treatments with Rogor and Croneton. All three chemicals reduced PLRV incidence. Therefore, delayed plantings and insecticides may reduce purple top, spindle sprout and PLRV. © 1986 Kluwer Academic Publishers.
