Abstract

Soybean a "miracle crop" is outstanding in its nutritive value. It has 43 percent biological protein and 20 percent fat. It is also rich in vitamins, mineral salts and essential amino acids. The intensity and distribution of weed species in the soybean crop are functions of a complex interaction among soil properties, rainfall patterns, temperature and cultural practices. Soybean yield losses resulting from weed interference and the cost of weed control constitute some of the highest costs involved in the production of the crop Looking to the potential of microbial herbicides, the present paper was based on develop and exploit some indigenous strains of fungal pathogens as bioherbicides to manage some of the problematic weeds of soybean. On the basis of primary screening 40 fungal strains isolated from various parts in which five of the most potential ones were selected for secondary screening. These were against screened and Aspergillus sulphureus was found to be the most potential agent effective against a wide range of host and induced maximum phytotoxic damage and thus, selected for further investigation.
