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

An experiment was conducted during 2011-2012 and 2012-2013 at farmers field of Gokak taluk, Belgaum district, Karnataka state to find out the efficacy of azoxystrobin 23 per cent SC anthracnose disease of mango. Results revealed that, two sprays of azoxystrobin 23 % SC @ 0.2% effectively controlled the anthracnose disease (12.23% as against 56.88% in control) followed by azoxystrobin 23%SC @ 0.15% (13.53%) and azoxystrobin 23%SC @ 0.1% (18.50%). The intensity of the disease was highest in control (56.88%). The treatment azoxystrobin 23%SC @ 0.2% recorded the highest yield of 67.84 kg/tree followed by azoxystrobin 23%SC @ 0.1%(66.34kg/tree) and azoxystrobin 23%SC @ 0.15% (63.34kg/tree).Keywords

Two to three sprays of pyraclostrobin 13.3% + epoxyconazole 5%(Opera 18.3%)@0.15% effectively controlled the Sigatoka leaf spot disease but this treatment was as par with propiconazole 0.1 per cent. The next best treatments were pyraclostrobin 13.3% + epoxyconazole 5% (Opera 18.3%)@0.125% and epoxyconazole 7.5%EC.With regard to yield, the treatment propiconazole @ 0.1 % recorded the highest yield of 31.94 t/ha followed by pyraclostrobin 13.3% + epoxyconazole 5%@0.15% (29.95 t/ha) and it was lowest in control. Phytotoxicity symptoms like chlorosis, necrosis, wilting, scorching, hyponasty and epinasty were not noticed in any of the treatments.Keywords
