The present work aims at investigating and evaluating the effect of fungicide (propineb70% W.P) and bacterialcide (protecto 9.4% W.P) at different concentrations against eggs, immature stages (one, four and eight weeks) and adult stage of Eobania vermiculata and Helicella vestalis by using leaf dipping technique under laboratory conditions (20°±2c° u0026 65%±5 R.H).Results revealed that, eggs was more sensitive to propineb 70%, since H. vestalis recorded higher mortality percentage compared to E. vermiculata. The % mortalities were (27, 47, 83 and 93%), (20, 40, 80 and 90%) respectively at the concentrations (0.1, 0.2, 0.3 and 0.4 %), with LC50 values (0.17 and 0.19%), respectively. Regarding immature stages (one week) also, H. vestalis recorded higher mortality percentage than E. vermiculata (23, 40, 73 and 97%) and (20, 33, 70 and 93%) respectively at concentrations (0.2, 0.4 0.6 and 0.8%). But for four weeks age was more sensitive than eight weeks and adult. As for in case of protecto 9.4% W.P also, eggs were more susceptible than immature stages and adult. A high mortality percentage was recorded to H. vestalis compared to E. vermiculata (20, 33.30, 70 and 76.70%) and (10, 30, 60 and 70%) respectively at concentrations of (0.2, 0.4, 0.6 and 0.8%) while for immature stages (one week) also, it was more sensitive than four, eight week and adult for H. vestalis compared to E. vermiculata. Generally eggs and immature stages (one week) of H. vestalis were more sensitive to propineb 70% and protecto 9.4% compared to E. vermiculata and propineb 70% was more effective than protecto 9.4% for all stages.
