conducted to study the toxicity of 2,4-D using EC50 value
in four dilutions. 2,4-D
was applied at concentration of 25, 50, 75, 100, 200 and 300 mg l-1 in the
potato Dextrose agar medium. The effect of this herbicide was evaluated as the
colony forming unit (CFU). EC50 value for 10-3 dilution of soil was 138±5.944 mg l-1. Soil physico-chemical
parameters and mycofloral properties were also
evaluated. Qualitatively 10 genera of fungi were observed in untreated soil,
whereas 4 genera were found in 2, 4-D administered dose. Key
