Abstract
The effect of three herbicides namely Agroxone, Atranex 50SC and 2,4-Damine on Azotobacter vinelandii, Rhizobium phaseoli and Bacillus subtilis were studied. These bacteria were isolated from a bean-garden in Lagos. The results revealed that 2, 4-Damine was the most toxic of the three herbicides studied and Azotobacter vinelandii was found to be most sensitive to the herbicides. There was a reduction in LC50 of herbicides with increased number of days. The percentage survival decreased with increased concentration of herbicides and days for Rhizobium phaseoli and Azotobacter vinelandii while an initial reduction in population was followed by increased percentage survival of organisms for Bacillus subtilis.
