ABSTRACT

Efficacies of different fungicides were evaluated in managing botrytis grey mould of chickpea. This field experiment was conducted in two sub-station of Bangladesh Institute of Nuclear Agriculture (BINA): Magura and Ishwardi. Fungicides increased seed germination over control in field condition both in Magura and Ishwardi. Seed germination percentage in Magura and Ishwardi was higher in Bavistin treated plots 95.25% and 93.87% respectively. Fungicides treated plots showed lower disease incidence over control. In Magura incidence of botrytis grey mould of Binachola-3 was recorded highest in control plots (5.91%) and lowest in Bavistin (2.04%). In Ishwardi lowest incidence was recorded at Bavistin (3.15%) and highest was recorded in control plots (6.54%).  Disease incidence reduction over control for Magura and Ishwardi were 65.48% and 51.77% respectively. Plant height, plant stand, number of pod per plant, number of seed per pod, unfilled pod per plant, seed weight per plant and dry plant weight was observed higher in treated plots over the control plots both in Magura and Ishwardi. Bavistin treated plots resulted the lowest botrytis grey mould incidence with higher yield components than the non-treated plots. Others treatments such as Secure, Biofungicides, Ridomil gold, Rovral, nativo, Dithane M-45 also showed significantly the better results (in reducing) for management of botrytis grey mould of chickpea than the control plots in the fields.

Key words: Fungicides, efficacy, botrytis grey mould and chickpea
