Abstract: The effect of fertilizers activators on microbial growth and capability in degrading IX and p-endosulfan was studied by incubating, two groups of microorganism in the presence and absence of four fertilizers (urea, triple super phosphate, urea + triple super phosphate and cow manure) for 45 days with sample drown every 15 days. Drawn sample were examined for microbial growth, concentration of starting material remained and a mount of sulphate generated. Results indicated that all activators caused significant increase in microbial counts especially the triple super phosphate followed by urea + triple super phosphate, cow manure and urea. Significant reduction in halflives of IX and p-endosulfan accompanied with various level of sulphate generation was noticed. Since, the microorganism studied have shown great potential in degrading endosulfan therefore any enhancement in their numbers and activity (caused by activator) will no doubt promote their capability in degrading endosulfan in soil.
