Abstract
Parthenium has now become one of the world’s seven most devastating and hazardous weeds. Though literal meaning of the word parthenium is medicinal uses but actually it is the most harmful for man, animal, plants and after all for environment and biodiversity. Now-a-days parthenium invades not only roadside, vacant land, railway track, wasteland but also farmland and agricultural field. In Malda district mango cultivation is the prime agricultural activity and 50% of the district populations are engaged with mango production. Now parthenium population is rapidly increased in mango field and the people worked in mango field are suffering from several diseases like asthma, fever, skin rashes and eczema. Reducing agricultural field is another burning problem of the district. So from this research work an attempt has been made to protect people and environment from these toxic weeds and try to use this weed to alternative purpose for human benefit.
