Abstract: Gladiolus is an important commercial bulbous crop. The major concern in commercial production is the Fusarium yellows or Fusarium wilt or corm rot caused by Fusarium oxysporum f. sp. gladioli. The fungus can survive for a very long period as mycelium, chlamydospores, microconidia and macroconidia in infected corms and soil. Fusarium invades the vascular system of the plant. Therefore, chemical treatment with contact fungicides is not very effective against pathogen which is inside deep lesion and express in next season resulting in huge losses. Therefore, to manage the disease integrated approach should be followed by combining sanitation, systemic fungicides, physical and bio-control methods for corm and soil treatment. The carbendazim, hot water and Trichoderma harzianum were reported effective to control the soil-borne pathogen under chemical, physical and biological class respectively. Therefore, these treatments and their combinations were tested for management of Fusarium corm rot in gladiolus cv. ‘Arka Amar’ under Bengaluru conditions. The corm treatments significantly reduced the disease during storage. The integrated corm treatments were found effective against corm rot without adverse effect on plant growth and flowering. It also significantly increased the number of daughter corms.
