BBCH-scale

BBCH-scale

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, fertization, 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 [cite journal
last = Zadoks
first = J.C.
coauthors = T.T. Chang, C.F. Konzak
title = A decimal code for the growth stages of cereals.
journal = Weed Research
volume = 14
pages = 415–421
date = 1974
doi = 10.1111/j.1365-3180.1974.tb01084.x ]

Officially, the abbreviation BBCH derives from Biologische Bundesanstalt, Bundessortenamt and CHemical industry. Unofficially, the abbreviation is said to represent the four agrichemical companies (Bayer, BASF, Ciba-Geigy and Hoechst) that sponsored the initial development of the system.
