Solid substrate fermentation, Mycoherbicide, Sclerotium rolfsii, Field evaluation

Mass production of mycoherbicidal agent Sclerotium rolfsii (FGCC#02) under solid substrate fermentation was standardized. Mycoherbicidal potential of inoculum, grown on twenty agro wastes, applied on Parthenium at pre-emergence and post emergence stage was determined. Wheat grains and host leaves colonized inocula incited severe infection and was responsible for significant mortality at pre-emergence application while tea-bagasse-wheat bran-wheat straw (TBWW) was highly effective at post emergence stage. Contrary to these, waste cotton failed to cause appreciable mortality at both the stages.
