Roving survey was conducted in major banana growing regions of Karnataka during 2011-12 and it revealed that the disease incidence ranged from zero to hundred per cent. Maximum incidence was recorded on Kadali variety in Bangalore followed by Mysore (Devarasanahalli) (51.0%), Nanjanagudu (48.0%) and Mandya (Bukanakere) (44.0%) on Rasthali and Ney Poovan cultivars. The disease was not observed in Belgaum area. Pseudostem vascular infection was maximum (6.0) in cultivars of Rasthali and Ney Poovan in Nanjanagudu, Devarasanahalli and Bukanakere.Keywords

Investigations were undertaken in pot to assess a possible interaction between Panama wilt of banana caused by Fusarium oxysporumf. sp. cubense and burrowing nematode Radopholus similis. The disease incidence was highest in inoculation of burrowing nematode (Radopholus similis) followed by Fusarium oxysporum f. sp. cubense and inoculation of Fusarium oxysporum f. sp. cubense followed burrowing nematode (Radopholus similis) and simultaneous inoculation of Fusarium oxysporum f. sp. cubense and burrowing nematode (Radopholus similis). Plant growth parameters were least in simultaneous inoculation of Fusarium oxysporum f. sp. cubense and burrowing nematode (Radopholus similis).Keywords

Effect of different temperature, light intensity and pH were tested against the growth and sporulation of Colletotrichum musae under in vitro conditions. Results indicated that the growth of Colletotrichum musae was maximum at 30 °C (72.25 mm) followed by 25 °C (68.25 mm), 20 °C (53.00 mm), 15 °C (52.75 mm) and it was lowest growth (12.00 mm) at 35 °C. Exposure of Colletotrichum musae to alternate cycles of 12 hr light and 12 hr darkness, continous light and under normal condition (room temperature) resulted in the maximum mycelial growth (90.00 mm) and heavy sporulation. The variation in growth of Colletotrichum musae at different pH were found to be significant. Result of the study revealed that at pH 7.0 fungus produced maximum growth of 977.0 mg followed by 960.0 mg at pH 8.0, 957.0 mg at pH 6.0, 948.0 mg at pH 5.0 and 922.0 mg at pH 4.0.Keywords
