- Observation Late blight was absent.
- Intervention effect Copper oxychloride was the only fungicide consistently increasing yield in the wet season at Rakamanda.
- Intervention effect The extra yield benefit from seven-day rather than 14-day spraying was small.
- Intervention effect Fourteen-day copper oxychloride spraying increased Sequoia yield at Taluma from 21–8 to 26.2 t/ha.
- Intervention effect Fourteen-day copper oxychloride spraying increased Sequoia yield at Rakamanda from 26.4 to 300 t/ha as printed.
