Abstract:

Bakanae disease is becoming a serious threat to basmati production and had been reported to cause 20-50% loss in total production. Bakanae disease caused by Fusarium moniliforme is an emerging and very serious problem of basmati rice. It occurs in both upland and low land rice field. The typical symptoms of the disease are abnormal elongation of seedlings, foot rot and seedling rot of rice. The pathogen survives mainly in seed and in soil also. Therefore seed treatment for the management of seed borne pathogen is most effective method of disease management. Seed treatment with bio-agent for the management of diseases is an eco- friendly method of disease management. Keeping this in view in present investigation different isolates of Trichoderma were tested in the management of bakanae disease of basmati rice as seed treatment. Trichoderma powder was applied for seed treatment @ 6 g/kg seed alone and in combination with different fungicides 2 g/kg seed. Experiments were conducted in pot condition. The observations were recorded on seed germination, number of tillers and disease incidence after 30 days `of seed sowing. Two fungicides (nativo, saaf) and two isolates of Trichoderma (S1, and S7) were tested in pot condition against Fusarium moniliforme. Maximum (90%) germination was recorded in case of seed treatment with Trichoderma-S7 followed by 83.33% in Trichoderma S7+nativo. Minimum (22.85%) disease incidence was recorded in case of the seed treated with Trichoderma-S7. Maximum disease incidence (76.6%) was recorded in case of control. Among the fungicides and bio-agent, seed treatment with Trichoderma-S7 was most effective for the management of bakanae disease of rice. The selected fungicides and bio-control agents were evaluated as seed and seedling treatment for controlling bakanae disease under field conditions. Among three fungicides evaluated as seed treatment, minimum disease incidence (0.0%) was observed in seed treatment with Tricoderma-S1 followed by seed treatment with Tricoderma-S1+saaf (0.1%). Maximum disease incidence was observed in the case of control (0.75%) followed by seed treatment with Trichoderma (0.49 %). Maximum yield (40 q/ ha) was recorded in case of treatment of Trichoderma-S1 which was found most effective for the management of bakanae disease of rice.
