Biological control of weeds is the deliberate use of natural enemies to suppress the growth or reduce the population of a problem weed species. Augmentation of indigenous fungal plant pathogens (bioherbicides / mycoherbicides) is a bio control strategy which involves the application of living inoculum of an endemic plant pathogen, generally a fungus, in a manner very similar to that of a chemical herbicide. Bioherbicides are applied in an attempt to overcome disease restraints by periodically dispersing an abundant supply of virulent inoculum onto a susceptible weed population. The...
