| Abstract;On the acute wilt of melon in Kagoshima Prefecture, the causal organisms were studied in 1985-1991. Summary of the results are as follows: 1. Symptoms of the acute wilt appeared firstly as yellowing of lower leaves and wilting on daytime in fruit enlarging period. And then the disease developed rapidly to withering stocks in harvesting period. 2. The roots of diseased plants of melon acute wilt were discolored water-soaked brownish. 3. Pathogenic Pythium spp.(mainly P. splendens), Monosporascus cannonballus and Rhizoctonia solani on melon plant were isolated from the diseased roots of melon acute wilt. 4. The acute wilt symptoms were reappeared by cultivating melon in the soil inoculated P. splendens or M. cannonballus. Therefore, it was considered that both fungi are related to the occurence of melon acute wilt. 5. Damage of melon roots caused by pathogens were influenced by fruiting number of melon, and also by the parasitism of root-knot nematodes were the same. 6. The outbreak of melon acute wilt was perfectly controlled by the soil disinfection with chloropicrin. (author abst.) |
