Other claims from this paper (19)
- Observation Plain-region potato yield decreased 32.8~66.3% in the first cultivation year.
- Observation Virus infection in the first year was 92.9 to 95.4%.
- Observation Twenty species across three plant families were susceptible to PVX.
- Observation Salvia officinalis was a PVX carrier.
- Observation Digitalis purpurea showed masked symptoms.
- Observation Most Solanaceae plants developed necrosis and ring spot.
- Observation Ring spot occurred in Nicotiana tabacum L. var. White Burley and N. glutinosa.
- Observation The eight virus strains had a thermal inactivation point of 68-.
- Observation The dilution inactivation point exceeded 1,000,000 dilution.
- Observation Virus ageing in vitro was 240-360 days.
- Observation Virus ageing in dry plant tissue was 30 days.
- Observation Myzus persicae and Oxya spp. did not transmit the virus strain.
- Method / resource Purified virus yielded antiserum titer 1/2048.
- Intervention effect Chenopodiacae markedly inhibited potato virus infection.
- Intervention effect Earlier planting of sprouted seed tubers prolonged growth period by 10 to 12 days.
- Intervention effect Earlier harvest reduced seed-potato virus infection.
- Observation Chemical treatment effects lasted about 60-70 days.
- Intervention effect Single foliar application was ineffective for potato virus control.
- Intervention effect PSP 204, Disyston and Thimet greatly controlled potato leaf roll virus, particularly twice-applied PSP 204.
