Inhibitory effect of plant extracts on Colletotrichum gloeosporioides - the causal agent of postharvest rot in papaya fruits.

To evaluate the effect of plant extracts on the growth and sporulation of Colletotrichum gloeosporioides [Glomerella cingulata], aqueous extracts from garlic, peppermint (Mentha piperita), castor bean (Ricinus communis) and peppers (Capsicum spp.) were incorporated into potato-dextrose-agar (PDA) at concentrations of 100, 200, 500, 1000, 5000 and 10000 mg/g. Mycelial growth and conidium production were evaluated in these media. All extracts exhibited inhibitory effects at 200 mg/g and above. Garlic extract inhibited mycelial growth by 5.3-67.6%; however, it had no effect on sporulation. Peppermint, castor bean and pepper extracts promoted mycelium inhibition and reduced conidium production by 41-84%, depending on the extract concentration.
