Eisenia fetida was exposed to two selected fungicides, carbendazim and captan. Previously determined LC50 value of the two fungicides were 5.38mg/kg soil and10.41mg/kg soil respectively. The specimens were exposed to sub lethal doses of both the fungicides, i.e. 25% of LC50 (T2) value and 50% of LC50 (T3) value, along with the control set (T1). The acute toxicity test i.e. 96 hours mortality test showed the carbendazim as more toxic over captan. The enzyme activity measured on the 28th day. The acid phosphatase activity inhibition was observed in both the fungicides in both the doses but in case of alkaline phosphatase activity in both the fungicides in both the doses was increased. The inhibition in the level of acid phosphatase may occur to encounter the stress situation and the changes in the alkaline phosphatase activity may be indicative of an adaptive rise.
