Other claims from this paper (13)

- Observation All six symptomatic field samples contained at least one potyvirus.
- Intervention effect Sap from three field samples induced mosaic symptoms in watermelon.
- Intervention effect One field sample caused vein yellowing in inoculated squash.
- Intervention effect One field sample caused death of inoculated watermelon plants.
- Observation SqVYV was detected in five of six field samples and symptomatic inoculated plants.
- Observation The amplified sequence was identical to SqVYV.
- Observation PRSV-W was identified in two of five SqVYV infected field samples.
- Observation No other potyvirus infection was found.
- Observation This was the first reported SqVYV occurrence outside Florida, in Indiana.
- Recommendation Authors judged the observed SqVYV occurrence to pose little or no production threat.
- Recommendation Authors advised growers not to change growing practices because of SqVYV.
- Observation SqVYV occurrence did not appear to explain long standing mature watermelon vine decline in Indiana.
