Out of the 4 alien invasive species three are of high risk namely Mikania micrantha, Chromolaena odorata and Mimosa diplotricha. Lantana camara is found to be medium risk.

The herbicide is widely used by farmers to control the weeds are capable to cause various health problems including genetic aberration. So an effective and comprehensive weed management strategy have to be developed in the country to combat the threats of IAS in agriculture fields.
