Abstract

Sixty-five mungbean genotypes were screened for resistance against Cercospora leaf spot under disease epiphytotic condition. The disease symptoms initiated on the lower side of the old leaves of susceptible genotypes and progressively spread all over the plant. Considerable variations among the genotypes were observed with respect to disease reactions. Among the sixty-five genotypes, one genotype LGG-460 was found highly resistant while GM-02-08, GM-02-13 and GM-03-03 were categorized into resistant. However, fifty-two genotypes were found moderately resistant, while the rests of the genotypes were grouped into susceptible to highly susceptible. Minimum disease index (0.9) and Maximum disease control (70.1%) was recorded in the foliar application of Carbendazim (12%) + Mancozeb (63%) 75% WP at 0.2% concentration. However, Hexaconazole (5%) + Captan (70%) 75% WP and Mancozeb75%WP were also found statistically at par with 1.0 and 1.2 disease index and percent disease control were 61.3 and 62.7, respectively.
