We are running towards the era of biotechnology and this millennium is progressing towards the goal to achieve a control measure of pest in a sustainable manner to make the world free from pesticidal toxicity. A routine search of medicinal plants was done frequently in a random fashion in the local as well as forest areas of Paschim Medinipur District. After getting information from rural peoples we have collected different plants, which are commonly used by them for ailment. Our collection was mainly based on bark, leaves, roots, fruits etc. of different herbs and trees. The objective of our study is to find out suitable control method against noxious nematodes by applying plant products. The nematicidal activity of different plant products of over locality screened out in a random fashion. In vitro as well as in vivo test of a few plant products was done. We prepared aqueous extract in our laboratory from collected plant material and tried to determine their biological activity through in vitro test. After observing the positive effect from aqueous extract we further prepare alcoholic extract from a few plant products. Again we are trying to determine their biological activity of alcoholic extracts through in vitro test. Among them leaf extract of Polygonum barbatum is found to be most effective and highly promising in respect to future prospect of production of potential botanical pesticide.
