Eupatorium odoratum have invaded the waste lands of South West Bengal, India.A field study indicated a gradual and also significant increase in Eupatorium odoratum accompanied with significant decrease in other coexisting species.Considering the above in mind, a study was undertaken to evaluate the existence of inhibitory effect of leaf click here extracts and leaf leachates noxious weed Eupatorium odoratum using fully viable seeds of mung bean (Vigna radiata) as the bioassay material.The study showed the reduced the percentage germination and TTC stainability along with extended T50 values of mung bean seeds.

The levels of protein, DNA and RNA, activities of dehydrogenase and catalase enzymes were significantly retarded in pretreated seed samples.Amino acid and sugar levels were increased in the leachates of seeds pretreated with leaf extracts and leaf leachates.Thus, from the overall results it can be concluded that various inhibitors present in E.odoratum can impart strong inhibitory effect on mung bean.

The study suggests that the leaves tokidoki hello kitty blind box of E.odoratum possess phytotoxic or allelopathic chemicals which potentially rendered the inhibitory action on mung bean seeds.
