Intervention effect Formaldehyde treatment greatly decreased PMTV establishment.
Intervention effect Organo-mercurial fungicide greatly decreased PMTV establishment.
Intervention effect Fumigation with 2-aminobutane was ineffective.
Intervention effect Sulphur acidification greatly decreased infection by PMTV and S. subterranea.
Observation PMTV transmission resumed when treated soil pH rose.
Intervention effect Fungicides decreased infection of Nicotiana debneyi bait seedlings.
Intervention effect Calomel at 75 kg/ha controlled field spread of PMTV and S. subterranea to potato.
Intervention effect Zinc frit greatly decreased spread of both pathogens to potato.
Intervention effect Zinc sulphate greatly decreased spread of both pathogens to potato.
Intervention effect Zinc oxide greatly decreased spread of both pathogens to potato.
Association The zinc amount required rose with soil clay content.
Intervention effect Zinc treatment did not eliminate virus-carrying vectors from soil.
Intervention effect Zinc frit was phytotoxic due to boron content.
Intervention effect Potato tuber zinc content increased in treated plots but did not double.
Recommendation The authors recommended sulphur, zinc oxide or calomel for small early propagation plots.
