Anthracnose disease on chili is commonly caused by Colletotrichum sp. The disease
can easily spread when conducive environmental condition. Occurrence of this diseases
lead to increase of management cost and economic losses. This study is conducted to
evaluate the potential of pitaya and ginger extract to inhibit fungal activity through in
vitro and in vivo test. For in vitro test, pathogenic fungal isolates will be subculture
onto PDA ameliorated with the extract at different concentration, 5% and 20%.
Potential of microbial inhibition will be evaluated based on percentage of inhibition
zone. For in vivo, healthy chili will be dipped into different concentration of plant
extracts before inoculated with pathogenic fungal isolates. Appearance of lesion will
be calculated into disease severity scale. Less disease severity was regarded to have
a good potential in reducing anthracnose disease. Application of plant extracts in
disease management can prevent negative impact due to chemical control.
