N = non-synchronous crops S = synchronous. 1/ Stage of seedling inoculation with rust in the glasshouse 2/ Ripeness for binder (ca 16% water content); chlorophyll of inflorescence largely lost... A good understanding of the decimal code of growth stages (GS), the physiology of the plant at each stage and disease development will all help for sound management decision making, (Table 2.5). Three plant growth stages are particularly important for fungicide application decision-making. At GS 32 two nodes are detectable and leaf 3 is emerging. At GS 39 the flag leaf has completely emerged

The decimal code, which is divided into principal and secondary growth stages, is based on the well-known cereal code developed by ZADOKS et al. (1974) in order to avoid major changes from this widely used phenological key.The abbreviation BBCH derives from Biologische Bundesanstalt, Bundessortenamt and CHemical industry.
