We have identified a locally growing weed known as Parthenium hysterophorus and we have extracted phytochemicals from the leaves of the plant and tested the phytochemical on pest that are attacking major crops. The pest showed resistance to our chemical and zone of inhibition was found. Therefore, we concluded that the phytochemical was having pesticidal properties and upon purification will work as CROP-DEFENDER. Our proposed product is a bio-pesticide which is quite different from chemical pesticides. Moreover, the product shall be prepared from a weed of no economic value. Secondly, the raw material can be cultivated at bare and non-cultivable lands with very less irrigation water. Thirdly, the product will be cheaper than the existing pesticides and bio-pesticides. Our product can mimic the activity of both pesticide and insecticide therefore it is a one for all type of product. So, a farmer buys one product but gets the benefit of two different products at the same time therefore our product will fetch the market very soon.
