    Abstract: A novel Phomopsis sp. fungus is an effective broad-spectrum bioherbicide agent for controlling several economically important pigweed species (Amaranthus spp.). The agent is a new species of the plant pathogen Phomopsis. Spores and mycelial fragments from the novel fungal species kill many different pigweed biotypes from various parts of the United States and other countries. Various compositions and formulations employing the novel fungus, including its combination with a hydrophilic mucilloid gel, can be used in methods for controlling pigweed.
