Effects: Armillaria is the most common root disease in the Southwest and may account for up to 80 percent of the root disease conifer mortality in the region. There are over 10 species of Armillaria, some are virulent parasites while others are opportunists that act selectively on small or weak individuals such as those shaded by taller plants.

    disease, annosus root rot (Heterobasidion annosum), or Phytophthora root rot can be colonized by Armillaria and thus lead to severe local outbreaks of the disease. A tree or shrub may die in one to several ye ars after initial infection, depending on the vitality of the plant and environm ental co Size: 76KB. Armillaria Root Rot (Also known as Mushroom Root Rot, Shoestring Root Rot, Honey Mushroom Rot) 4 should commit to planting a more diverse landscape because they tend to better withstand pests, diseases, and even severe weather events. Symptoms of Armillaria root rot often do not appear until 1–3 years after infection has taken place.

      Armillaria root rot is a potentially devastating disease of cherry. Once orchards are infected with Armillaria, annual loss of trees will continue to occur until the orchard is abandoned or removed. Because Armillaria remains in the soil for many years, infected orchard sites are not suitable for the production of stone fruits.
