The invention combines non- or low-virulent pathogens and special carriers as broad-spectrum bioherbicides to control weeds. The technique is especially suited for orchards and vineyards. There are several advantages to using broad- spectrum bioherbicides. There is a significant market for the product, and it reduces detrimental environmental effects. The invention is safe and can easily be applied by homeowners and farmers. Results of greenhouse studies are described for the effects of saprophytic or low-virulent pathogens applied in special carriers to a broad range of plants. By using specific carriers, organisms can be applied to target weeds with very little or no possibility of infecting nearby plants. Drift is extremely limited, and only plants which come into contact with the organisms will be damaged.
