Role of biocontrol agent for the management of foot and root rot disease of cauliflower

Abstract

The experiment was conducted at Regional Agricultural Research Station, Ishurdi, Pabna in Bangladesh during 2009-10 to find out the effect of bio control agent against foot and root rot of cauliflower. Five different forms of two biocontrol agents were tested for their performance against the causal pathogen. All the bio control agents showed significantly better performance over control. The lowest foot and root rot incidence (6.25 %) was recorded in soil amendment with Trichoderma harzianum compost (1.0 t/ha) treated plots and the highest (18.75 %) was recorded in control. The yield ranged from 17.91 to 23.05 t/ha, the highest and lowest yields were recorded in soil amendment with Trichoderma harzianum compost (1.0 t/ha) and untreated control, respectively.
