The control of sigatoka (banana leaf spot disease) by mist-blowing with Banacobre-Sandoz.

In Ecuador a special mist blower was constructed with a pipe 8 1/2 m. high, at the top of which were 6 downward-pointing outlets. A 3 % solution of Banacobre-Sandoz (a cuprous oxide with a sticker) was blown down on the upper leaf surfaces of banana rows on each side. The droplet size was 50-100 mu . Satisfactory control of banana leaf spot was obtained by using 100 1. spray per ha., in regular 3- or 4-weekly cycles from the beginning of January. Fruit washing was not necessary after using this spray. (Abstract retrieved from CAB Abstracts by CABI’s permission)
