Sixteen mungbean germplasms viz. Gk – 22, SMZ – 134, VC – 3669, VC – 3960 A – 88, VC – 3960 A – 89, VC – 6144, VC – 6144 (47 – 28 – 2), VC – 6148 (50 – 12), VC – 6153 –B – 20, VC – 6153 – 20P, VC – 6173, VC – 6173 B – 33, VC – 6372 – (45 – 8), VC – 6773 – B – 6, VC – 6897 and BARI Mung – 4 were screened against Cercospora leaf spot at Pulses Research Sub-Station (PRSS), Bangladesh Agricultural Research Institute, Joydevpur, Gazipur and Regional Agricultural Research Station (RARS), Jessore, Bangladesh during 2014 under the rainfed condition. The genotypes were categorized into 0 – 8 scale to determine the differential response of Mungbean accessions to Cercospora leaf spot. On the other hand, another experiment also conducts in the same time. In another field study efficacy of three chemicals namely Score (0.2%), Secure 600WG (0.2%), Bavistin 50WP (0.15 %) and one botanical Neem leaf extract (1:1), were evaluated to find out the effective management practices for Cercospora leaf spot of Mungbean at Golapgonj, Sylhet and PRSS, Joydevpur. The plot size was 3m × 4m and the experiment was laid out in a Randomized Complete Block design (RCBD) with three replications. Considerable variations among the genotypes were observed with respect to disease reactions, none of the genotypes were found to be highly resistant to the disease. Among the genotypes VC – 6153 – B – 20 showed the lowest disease incidence with the highest yield in both locations suggested that VC – 6153 – B – 20 may be a wonderful source of Cercospora leaf spot of Mungbean tolerance. Among all the treatments, Secure 660WG treated plots showed the lowest disease incidence with the highest yield. Hence, Secure 660WG (0.2%) may be recommended for controlling the disease of Mungbean
