Control of Soilborne Fungal Diseases on Muskmelon by Soil Disinfestation in Consecutively Cultivated Fields
Jung Sup Lee, Jang Jeon Choi, Jin Ho Choi, Yun Chan Huh
This study was carried out to determine the causal agents of soil-borne fungal diseases that pose a threat to the muskmelon production in Cheong Yang, Korea and to investigate the potential effects of hot water drenching and three fumigant (metam sodium, dazomet and methyl bromide) on these diseases. As the agents of the diseases, Monosporascus cannonballus, Didymella sp., Fusarium sp., Phytophthora sp., were detected. Hot water and the fumigants were treated on two successive cropping seasons of melon. Soil temperature was measured at 0, 10, 20 and 30 cm soil depth. In 2005, soil sterilization by hot-water was more effective significantly to control of the diseases than by fumigant. yield was the highest in hot-water sterilized plot as 39 ton·ha-1. Dazomet (50 g/m2) treated plot was followed as 23 ton·ha-1. In 2006, hot water sterilized plot showed higher yields than non-treated plots (14.8 ton·ha-1). But the other three fumigant contained Dazomet (50 g/m2) were no difference (P<0.05) in yield.
Key Words: Didymella sp., Fusarium sp., Hot water, Monosporascus cannonballus, Phytophthora sp.
