Assessment of Mungbean Seed Borne Disease Suppression by Chemical and Botanical Fungicides

Abstract

Effective disease management is essential for high quality and maximum production. We conducted this experiment to know the effects of different chemical and botanical fungicides to assess the prevalence of Cercospora spp. on mungbean seeds in vitro condition. The laboratory experiment was conducted in plant pathology laboratory, Department of Plant Pathology and Seed Science, Sylhet Agricultural University, Sylhet. Mungbean seed samples were collected from five different places prior to the experiment. Five fungal pathogens viz. Aspergillus spp., Penecillium spp., Cercospora spp., Rhizopus spp. and Fusarium spp. were detected from the collected seed sample by Blotter test method. Pathogens were identifies by observing their growth characters on the incubated seeds under stereo-binocular microscope. Total seven different treatments were applied randomly in both conditions as seed treatment and spray solution. For treating seeds, 250 mg of each fungicide along with 100 g seeds was taken separately in 250 ml Erlenmeyer flasks. The combined treatment (T5: Bavistin 50 WP+Secure 600 WP) was found to be the most effective in controlling seed-borne fungi when used as a seed treating agent in vitro condition.
