Abstract:

Grain mold is the major disease of kharif sorghum affecting grain yield as well as the quality of the produce. Study consisted of eleven different treatments including control on mold susceptible genotype, AKMS 14B of sorghum and was carried out at Sorghum Research Unit, Dr. Panjabrao Deshmukh Krishi Vidhyapeeth, Akola during kharif 2013. These treatments were T1 - Neem seed extract 10%, T2- Neem leaves extract 10% ,T3 - Eucalyptus leaves extract 10% , T4 - Ginger (rhizome) extract 10%, T5 - Garlic (cloves) extract 10%, T6 -Pyraclostrobin 0.1% (1 g/lit), T7- Propiconazole 0.1% + Mancozeb 0.3% (Propiconazole 1 ml/lit + Mencozeb 3 g/lit.), T8 - Thiram 0.2% + Carbendazim 0.1% (Thiram 2 g/lit + Carbendazim 1 g/ lit.), T9 - Propiconazole 0.1% + Thiram 0.3% (Propiconazole 1 ml/lit + Thiram 3 g/lit), T10 - Water spray, T11 - Control (No any spray). Two sprayings of the botanicals and fungicides were taken on sorghum genotype AKMS 14 B of which first spray was taken at complete anthesis stage and second at 15 days after first spray. To invite sufficient fungal load, regular water sprays were done. The observation was recorded on the association of the Fusarium moniliforme on sorghum cob at maturity stage. Association of Fusarium moniliforme at maturity stage in susceptible genotype AKMS 14B was in the range of 16.25 to 42.36 per cent. The minimum infection of F. moniliforme was recorded in the fungicidal treatment of Pyraclostrobin @ 0.1% (16.25%) followed by combination of Propiconazole @ 0.1% + Mancozeb @ 0.3% and Thiram @ 0.2% + Carbendazim @ 0.1% (20.00%), whereas in case of the botanicals, Garlic extract @10% (28.00%) and Ginger extract @10% (28.66%) were the best. Maximum association of the Fusarium moniliforme was observed in water spray (42.36%) and Neem leaves extracts @ 10% (41.40%) as against control (39.66%).Thus it was concluded form the present study that the fungicidal treatment of Pyraclostrobin @ 0.1% and botanical treatment of Garlic extract @ 10% were the best in reducing the association of Fusarium moniliforme at maturity stage in sorghum.
