The BBCH-scale is a scale used to identify the phenological development stages of a plant. A series of BBCH-scales have been developed for a range of crop species. Phenological development stages of plants are used in a number of scientific disciplines (crop physiology, phytopathology, entomology and plant breeding) and in the agriculture industry (timing of pesticide application, fertilization, agricultural insurance). The BBCH-scale uses a decimal code system, which is divided into principal and secondary growth stages, and is based on the cereal code system (Zadoks scale) developed by Zadoks[1]

BBCH officially stands for "Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie". The abbreviation of the scale is also said to unofficially represent the four companies that initially sponsored its development; Bayer, BASF, Ciba-Geigy and Hoechst. [2]
