The field efficacy of Beauveria bassiana in comparison with the commercial formulation of B. bassiana (Daman) and standard check malathion 50 EC against Hydaphis coriandri and Aphis craccivora showed significant variations among pre-treatment and post-treatment counts. H coriandri, one day after treatment (DAT) a significant reduction (70.22%) in the aphid population was observed in malathion 50 EC (0.05%) followed by Daman (15.22%). At 7 DAT, the highest population reduction was 92.81% in malathion 50 EC followed by Daman (83.41%) was recorded, whereas in A.craccivora one-DAT, a significant reduction (68.42%) in the aphid population was observed in malathion 50 EC (0.05%) followed by Daman (10.70%). At 7 DAT, the highest population reduction was 90.0% in malathion 50 EC followed by Daman 81.34% were observed. Daman showed significantly high percent of reduction (54.60%) and (47.35%) in H coriandri and A.craccivora, respectively. However, the standard check, malathion 50 EC were highly toxic and showed significantly high percentage reduction (84.85%) and (82.55%) in the both the aphids population.
