Pathogens

  • Oak Wilt leaf

    Oak Wilt

    Oak Wilt is a fatal vascular disease of oak trees caused by the fungus Bretziella fagacearum.This fungus infects the xylem (water-conducting tissues), obstructing the flow of water and nutrients which causes leaves to become discolored and wilt rapidly, eventually leading to the tree's death.

  • Potato wart

    Potato Wart

    Potato wart is a soil-borne fungal disease that deforms potato tubers by causing abnormal growths, or warts, which can severely reduce crop yields. This fungus does not pose a risk to human or animal health but has considerable economic implications for potato growers due to the damage it causes to the potatoes, making them unmarketable.
