  • Self-delimiting fungal mutants, bioherbicidal compositions thereof, method of preparing thereof and method of using thereof for weed control
    Patent number: 5538890
    Abstract: A broad spectrum biological herbicide comprises a mammal-sparing bioherbicide fungal mutant, e.g., a S. sclerotiorum mutant, of limited survival time and geographical dissemination characteristics under standard agricultural conditions. The invention also relates to a method of obtaining herbicides of the invention comprising obtaining viable wild type bioherbicide fungal spores, subjecting these to UV light to reduce the number of viable fungi to less than 5% the initial number of spores, selecting mutants which differ from the wild type in at least one characteristic such as altered phenotype or morphology, and further selecting a mammal-sparing bioherbicide fungal mutant of reduced survival time and geographical dissemination characteristics under agricultural conditions when compared with the wild type. The invention also relates to a method of using the broad spectrum biological herbicide to reduce the number of weeds in an area.
