The pepper plant growing in Kuala Terengganu has shown anthracnose disease. It
was before cultivated with pitaya and was severely infected with anthracnose caused
by Colletotrichum species. Therefore, this study was to confirm Colletotrichum species
isolated from pepper plant that may give similar severity on different hosts. We also
had applied sodium hypochlorite solution (250 ppm) for 1 or 3 minutes (dipping
technique) as an alternative treatment in controlling anthracnose. Identified
Colletotrichum gloesporioides was inoculated on pitaya stems and banana fruits (soft
fruit as pitaya). Result showed that there was no significant difference (p>0.05) for
all sodium hypochlorite treatment on bananas including postharvest parameters
(disease severity, colour, total soluble solid, pH, titratable acidity). However,
inoculated pitaya stems showed symptom of anthracnose where confirmed that
inoculum of previous pitaya plantation may affect the pepper plants. Therefore, control
measurement is important to reduce inoculum of Colletotrichum especially removing
any debris of pitaya.
