One of the important pathogens on tomato is Fusarium sp.causing wilt and fruit rot.This study aims to investigate the potency of water spinach (Ipomea aquatica) as a biofungicide for inhibiting growth and development of tomato fruit rot caused by Fusarium sp.
This study showed inhibiting ability of Dog-Supplies I.aquatica stem extract to Fusarium sp.growth ranges from 3.
40% to 8.67%, while inhibiting ability of leaves extract can reach 3.40% to 45.
55%.Resistance induction test showed that in vitro treatment of I.aquatica leaves Knitted Tops extract 20% can lengthen incubation time of Fusarium fruit rot compared to positive and negative control.
Leaves extract of I.aquatica 20% is potential as biofungicide.Key words: biofungicide, Fusarium sp.
, Ipomea aquatica.
