Abstract

  The management of weeds by chemical herbicides creating adverse effect on human and animal health so there is urgent need for alternative weed control option to save environment by an environmental friendly and sustainable options. Bioactive compound of fungi is great source for the development of new herbicide and its offer an ecofriendly alternative to control weeds. Here We have evaluated mycoherbicidal activity of cell free culture broth (CFCF) of selected strains against Cassia obtusifolia. Phytotoxic contents of natural metabolites present in CFCF of Curvularia lunata (FGCCW#33), Phoma herbarum (FGCCW#07), Myrothecium roridum (FGCCW#03) and Fusarium roseum (FGCCW#61) against Cassia obtusifolia were evaluated by seedling bioassays. In preliminary bioassay, the CFCF of FGCCW#03 of 28 days old were shown maximum phytotoxic effect on seedling of Cassia obtusifolia at 100% concentration. The symptoms were observed as browning and necrosis of weeds. With effective formulation and cheap mass production of this mycoherbicidal strains can possibly use as mycoherbicide for control of Cassia obtusifolia in future.
