An imposing palm tree affected by a fungal pest.Top rot is a disease caused by different species of pathogens such as Phytophthora palmivora, Rhizoctonia solani or Pythyum sp. These species of fungi affect the plant's roots, causing necrosis and damage to the crop's internal tissues. Lisbon, Portugal, where this photograph was taken, has been affected by a plague that forced the cutting down of many centuries-old palm trees traditional to the city's decoration.
