Management of Yellow Mosaic Disease of Mungbean Against Mungbean Yellow Mosaic Virus (MYMV) in Bangladesh

Abstract

The prime aim of the study was to manage of Yellow mosaic disease of mungbean against Mungbean yellow mosaic virus (MYMV) by using one newly release botanical nutrient and through three selected insecticides. BARI (Bangladesh Agricultural Research Institute) released variety BARI mung-5, three insecticides (Imidacloprid, Acmix and Sobicron) and one botanical nutrient PPN (Peak performance nutrients) were used in the experiment. The plants were grown for pulse production and natural inoculums were relied upon for the infection of MYMV. Growth parameters, yield attributes and physiological features were significantly influenced by the application of selected insecticides and PPN combinations. Disease incidence and disease severity of MYMV were significantly varied among the treatments. Application of Imidacloprid with PPN combination gave the lowest disease incidence (3.13, 5.24 and 6.24% per plot and 14.33, 15.49 and 21.87% per plant) at 30, 40 and 50 DAS, respectively while the highest disease incidence (7.77, 13.70 and 19.24% per plot and 39.33, 48.20 and 56.63% per plant) were found in control at 30, 40 and 50 DAS, respectively. Application of Imidacloprid with PPN also gave the lowest disease severity (5.00, 6.00 and 13.33% at 30, 40 and 50 DAS, respectively while the highest disease severity (27.33, 35.00 and 45.00%) at 30, 40 and 50 DAS, respectively were measured in control treatment when no insecticides and PPN was used. If the disease is established once in the field then it is difficult to manage. As the disease is transmitted by vector (whitefly), the growers are suggested to control the vector populations before reaching economic damage and severe disease infection.
