Abstract—In vitro efficacy six chemical substance were evaluated against Erwinia carotovora the causal organism of potato soft rot disease. E. carotovora was isolated from diseased potato tubers by dilution plate technique and different biochemical and pathogenicity test were performed to confirm the bacterial species. Six chemicals viz. Copper Oxychloride @ 0.2%, Mancozeb @ 0.2%, Boric acid @ 0.1%, Kasugamycin @ 0.02%, Carbendazim @ 0.3% and Sodium Hypochlorite @ 0.2% were tested against E. carotovora subsp. carotovora by well diffusion method. For each treatment there were four replications and tested chemical volume was 100 µl. Data were recorded up to five days of incubation. Maximum zone of inhibition (mm) was obtained after 48 hours of incubation with Copper Oxychloride (30.35 mm), followed by Mancozeb (20.15 mm), Boric acid (19.15 mm) and Kasugamycin (16.28mm). Copper Oxychloride produced the maximum growth inhibition (33.72%) of the pathogen, on the other hand Sodium Hypochlorite (2.68%) did not efficiently inhibit the growth of E. carotovora. Copper Oxychloride proved to be the best chemical followed by Mancozeb under in-vitro management against E. carotovora subsp. carotovora.
