F. oxysporum and C. capsici were sever pathogens on chilli which were caused Fusarium wilt and anthracnose disease respectively. The use of essential oils for the management of Fusarium wilt and anthracnose consider to be a non-hazardous to environment and human beings. Twenty different essential oils were tested for their antifungal activity against F. oxysporum and C. capsici in vitro by paper disc method. As results showed that among the tested essential oils, Cinnamon oil (82.00 mm), Geranium oil (85.44 mm) and Clove oil (55.00 mm) were completely inhibited the growth of spore germination in F. oxysporum while jojoba oil showed the less effective. In C. capsici the growth of spore germination was completely inhibited by Cinnammon oil (86.33 mm) and Gerenium oil (87.00 mm). Cinnammon oil, Gerenium oil and Clove oil showed the highest antifungal activity against the both pathogens.
