Fusarium wilt caused by Fusarium oxysporum and crown and foot rot caused by F. solani can result in serious economic losses on several cucurbitaceous crops, such as watermelon and cucumber in Korea. These diseases associated with soil-borne pathogens mainly induce wilting symptoms. They are extremely difficult to control and there are few effective management strategies to reduce damages. Information related to control efficacy of antifungal agents against Fusarium oxysporum and F. solani on inducing wilting symptoms on cucurbits is insufficient. In this study, 108 fungicides registered for controlling fungal disease occurring on watermelon and cucumber were tested to evaluate growth inhibition of Fusarium oxysporum and F. solani on potato dextrose agar medium. Two fungicides, cabendazim + kasukamycin and prochloraz manganese, forming large growth inhibition zone on medium showed against the two species of Fusarium. In the case of seedlings, the same results as mycelium inhibition test was shown. In further study, experimental trials will be carried out to investigate control efficacy of the promising fungicides against Fusarium wilt and crown and foot rot diseases on watermelon and cucumber in field conditions.
