Durisols are associated mainly with old surfaces in arid and semi-arid environments and accommodate shallow to moderately deep, moderately well- to well-drained soils that contain cemented secondary silica (SiO2) within 100 cm of the soil surface. Many Durisols are known as Hardpan soils or Duric Kandosols (Australia), Dorbank (South Africa), or Durids (United States of America). In the Soil Map of the World (FAO–UNESCO, 1971–1981) they are the Duripan phases of other soils, e.g. of Calcisols. (IUSS Working Group WRB. 2015. World Reference Base for Soil Resources 2014, update 2015 International soil classification system for naming soils and creating legends for soil maps. World Soil Resources Reports No. 106.

Rice blast disease is one of the most devastating fungal diseases that can impact more than 50 species of grasses, including rice, barley, wheat, oat, and millet. Magnaporthe oryzae (synonym Pyricularia oryzae) is the causal agent responsible for rice blast disease.
