- Observation F. moniliforme was recovered from coca fruit in Peru, including all fruit parts in some fruit.
- Observation F. oxysporum was isolated from 33% of plated coca fruit.
- Observation The seed coat yielded the largest share, 35%, of these F. oxysporum isolates.
- Association Asymptomatic coca plants yielded slightly more isolates, 57%, than symptomatic plants at 43%.

- Observation Six pathogenic isolates originated from coca fruit pedicels.
- Observation Eight pathogenic isolates originated from coca fruit pericarps.
