3.1 Effect of aqueous and alcohol plant extracts on
mycelial growth and spore germination of mango fruit rot
fungi
Table 1 shows that aqueous and alcohol extracts of both
Azadirachta indica and Vernonia amygdalina significantly
reduced mycelial growth and spore germination of
Colletotrichum gloeosporioides. Alcohol extract of Vernonia
amygdalina was superior to other extracts in mycelial growth
reduction. It reduced radial growth of mycelia to 3.0
centimeters representing 62.5 per cent reduction and spore
germination to 127.33 millimeters representing 66.11 per cent
reduction when compared with the mycelial growth and spore
germination in the control. Aqueous extract of Azadirachta
indica also significantly reduced radial mycelial growth to 3.5
centimeters representing 56.25 per cent reduction and spore
germination to 134.30 milliliters representing 64.25 per cent
reduction. Benomyl was the most superior in the reduction of
mycelial growth with a record of 0.00 centimeter growth
representing 100 per cent growth reduction and spore
germination of 27.67 milliliters representing 92.63 reductions.
