Field experiments were conducted at crop research center (Gaja) of College of Forestry and Hill Agriculture, GBPUA&T, Ranichauri during the year 2006-2009 to test the effectiveness of entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae in comparison with an chlorpyriphos against cutworm, Agrotis ipsilon on potato. Lowest tuber damage (15.6%) was recorded in treatment of M. anisopliae (5.0x1011 spores/g) followed by B. bassiana (5.0x109 spores/g) with tuber damage of 17.82% as compared to control (31.82%). Highest yield of 126.97 q ha-1 was recorded in M. anisopliae treatment. However, among all the treatments, chlorpyriphos was found to be the most effective at lowest tuber damage (8.80%) with 142.01 q ha-1 yield while in control it was 65.78 q ha-1. Cost benefit ratio also revealed that application of higher dosage of M. anisopliae proved most effective followed by B. bassiana.Downloads
