Evaluation Of Indigenous Techniques Against Pulse Beetle Callosobruchus Maculatus (F.) In Black Gram

Abstract

Indigenous techniques viz., match boxes @ 10 no, lime powder @ 15 g, camphor @ 1 g, common salt @ 200 g, cow dung ash @ 80 g, buffalo dung ash @ 80 g, cow dung powder @ 100 g, buffalo dung powder @ 100 g, goat pellet powder @ 100 g/kg grain, gunny soaked in cow urine, gunny soaked in buffalo urine were evaluated as grain protectants against pulse beetle Callosobruchus maculatus (F.) in stored black gram at the Post Harvest Technology Centre, Bapatla. There was no adult emergence and grain damage in the treatments of dung powders besides camphor and ash even after six months. Further, the germination of stored seed kept with camphor, dung ashes and powders were good which ranged between 84.33% and 92.33%. A total of 3622.67 adults emerged from the untreated grain in 180 days of storage and caused 57.67% grain damage which resulted in 4.67% germination only. Besides filling up of inter-grain space, keeping a surface layer of 2.5 cm of powdered materials like ash and cattle dung could prevent pulse beetles successfully.
