Definitions

  • Fungi are plants which obtain their nutrition from an organic carbon source.
  • the body of the fungus secretes enzymes which degrade the organic substrate on which they are growing and yield smaller entities. These in turn are absorbed into the body of the fungus and are metabolized and provide energy to carry on vital processes.
  • the control of phytopathogenic fungi is of great economic importance since fungal growth on plants or on parts of plants inhibits production of foliage, fruit or seed, and the overall quality of a cultivated crop.
  • fungicide compositions which contain an inorganic bicarbonate or carbonate compound. It is known that bicarbonate and carbonate compounds exhibit fungicidal properties for agricultural purposes.
  • Japanese patent 56043207 describes a biocidal composition containing sodium bicarbonate and a polyglycerol fatty acid ester. The biocide controls Penicillum diqitatum on oranges, Sphaerotheca fuliqenea on cucumbers, Piricularia oryzae on rice, and mosaic virus on tomatoes.
  • Japanese patent 60097909 describes a soil fungicide prepared by admixing slaked lime with sodium bicarbonate, potassium bicarbonate, boric acid and phenolphthalein.
  • German patent DE 2927994 describes a fungicide which consists of sodium bicarbonate incorporated into a food-compatible surfactant such as saccharose laurate.
