Other claims from this paper (11)
- Observation The sugar beet virus causes symptoms similar to the Californian virus.
- Observation The minimum feeding time for aphids to acquire the virus from infected sugar beet leaves was 6 hours.
- Observation The minimum time for aphids to acquire and transmit the virus was 12 hours.
- Intervention effect Increasing feeding time on infected plants up to 2 days greatly increased the ability to transmit the virus.
- Mechanism Susceptibility of sugar beet to infection may account for part of the delay in infecting healthy plants.
- Observation The virus was accompanied in beet by a second virus.
- Observation The second virus YNMYV did not infect Nicotiana clevelandi Gray.
- Observation Yellow-net virus could not be recovered from Nicotiana clevelandi Gray by aphids.
- Observation The virus is not transmissible by inoculation with sap from infected plants.
- Mechanism YNMYV may be a carrier virus without which YNV cannot be transmitted.
- Association YNMYV causes symptoms similar to other sugar beet mild yellowing viruses.
