INTEGRATED APPROACH FOR MANAGEMENT OF RHIZOME ROT OF GINGER CAUSED BY Fusarium oxysporum

Abstract

An experiment was conducted at Sheree-Bangia Agricultural University on integrated approach for management of rhizome rot of ginger caused by Fusarium oxysporum during 15 March'2011 to February 2012. There were sixteen treatments used including untreated control such as Bavistin 50WP, Poultry waste + Ridiomil gold MZ 72, Poultry waste+ neem leaf extract, Saw dusts + alamanda leaf extract, Poultry waste+ Bavistin 50WP, Saw dusts+ neem leaf extract, Trichoderma harzianum, Poultry waste, Saw dusts+ Ridomil gold MZ 72, Poultry waste+ alamanda leaf extract, Saw dusts, Saw dusts+ Bavistin 50WP, Ridomil gold MZ 72, neem leaf extract, alamanda leaf extract. Rhizomes were treated with Bavistin 50WP, Ridomil gold, neem leaf extract, alamanda leaf extract and Trichoderma harzianum. Poultry waste and saw dusts were applied in the plot during land preparation. The lowest disease incidence (2.77%) and the highest reduction of disease incidence (95.66%) over untreated control were counted in Poultry waste+Bavistin 50WP followed by Poultry waste+Ridomilgold MZ 72), Poultry waste + Alamanda leaf extract, at 240 DAP. The highest disease incidence (63.88%) was recorded in untreated control. The lowest disease severity (8.23%) and the highest reduction of disease severity (84.62%) over control was recorded at 240 DAP in Poultry waste+Bavistin 50WP followed by Poultry waste+alamanda leaf extract. The highest number of tillers (60) per hill, the highest plant height (65.20 ern) per plot, the highest weight (3039 g) of the healthy rhizome per plot and the lowest weight (307.3 g) of infected rhizome per plot was recorded in case of Poultry waste+Bavistin 50WP. The highest rhizome yield (16.73 tlha) was achieved in Poultry waste+Bavistin 50WP which was 172.92% increased over the untreated control followed by Til (16.24 t/ha). Poultry waste+a1amanda leaf extract was also showed better yield (16.24t1ha) Performance,
