Our company’s scientist invention relates to the use of compositions comprising herbal preparations for the treatment and prevention of plant diseases caused by soilborne pests such as nematodes, fungi and insects. Said compositions comprise effective plant-derived anti- nematode, antifungal and anti-insect agents with minimal harmful effect to the environment. A further avenue of research in the quest for alternative anti-nematode agents is the investigation of plant, e.g. herb, species that exhibit high levels of nematode resistance with a view to developing a plant-derived nematicide. Some plant species are known to be highly resistant to nematodes. We are used best documented of these include marigolds (Tagetes spp.), rattlebox (Crotalaria spectabilis), chrysanthemums (Chrysanthemum spp.), castor bean (Ricinus communis), margosa (Azardiracta indica), and many members of the family Asteraceae (family Compositae) (Hackney & Dickerson, 1975). In the case of the Asteraceae, the photodynamic compound alpha-terthienyl has been shown to account for the strong nematicidal activity of the roots. According to above role of plant against soil born diseases our scientist extracted alkaloids from the same and form “Giant’ anti- nematode, antifungal and anti-insect preparation
