A checklist of weed species found in the area is given. The checklist includes the scientific and vernacularnames, life cycle, life forms and availability. Forty-eight weed species belonging to 19 families are reported. Maximum numbers of weed species were belonged to the family Asteraceae followed by Solanaceae, Poaceae and Brassicaceae.
