Field transmission of the potato spindle tuber virus and virus X by cultivating and hilling equipment

  • F. E. Manzer

Studies conducted over the past three years have shown that the spindle tuber virus and virus X can be disseminated very readily in potato fields by contact of healthy vines with contaminated cultivating and hilling equipment. Nearly 100% transmission of each virus was recorded in the Katahdin and Kennebec varieties in tests which simulated excessive contact of large vines with contaminated equipment. Under conditions of less severe vine contact a lesser amount of transmission of each virus was observed. When cultivation and hilling operations were performed before vines were large very little transmission of either virus was obtained. Greenhouse readings of indexed samples from the spindle tuber dissemination studies showed very close agreement with field readings.
