An investigation was undertaken to explore the biocidal efficacy of fungicidal
compound(s) produced by Calothrix elenkenii against damping-off disease in
three vegetable crops-tomato, chilli and brinjal. Treatments included application
of seeds soaked in water (control), culture filtrate and ethyl acetate extract of
Calothrix elenkenii and Metalaxyl in potting mix inoculated with Pythium
aphanidermatum in plastic pots. The observations taken after a period of four
weeks revealed the superiority of seed treatment with ethyl acetate extracts, in
terms of percent mortality and plant parameters. ANOVA revealed that the
treatments, crops (tomato, chilli and brinjal) and their interactions exerted a
significant influence on the parameters analyzed. Chilli recorded the highest
percentage of survivors and responded best to the seed treatment with ethyl
acetate extract of Calothrix elenkenii. Future work is being undertaken towards
formulation of a biocontrol agent using Calothrix elenkenii and understanding the
molecular basis for the biocontrol properties.
