Anthracnose is a common disease of tomato that causes post-harvest losses usually<br />

during storage and ripening. This study was carried to observe the effect of different<br />

concentration of kelampayan leaf extract (T1 0.5%, T2 1.25% and T3 2.5%) on the<br />

growth of Colletotrichum gloesporioides for in vitro. The extracts were also tested on<br />

tomato inoculated with this plant pathogen to assess effectiveness in retain<br />

postharvest quality. We observed an inhibition of mycelium growth with an increased<br />

concentration of the extract. Extracts at 1.25% and 2.5% concentration lowered the<br />

rate of weight loss, reduce the accumulation of lycopene and the percentage of<br />

disease severity (p
