New BBCH growth stage keys
The BBCH* growth stage keys aim to provide a standard and uniform description of the visible growth stages of plants, using a two-digit decimal code. This system has been developed for many important crops, such as cereals, rice, maize, rape, potato, fruit trees, small fruits, vegetables (see EPPO RS 2016/204). In 1997, the BBCH growth stage keys were recommended by the EPPO Working Party on Plant Protection Products and by Council for use in EPPO countries, thus replacing the previously recommended EPPO growth stage keys. The following new BBCH scales have recently been published to describe the growth stages of the following plants:
- Aegle marmelos (bael) (Kishore et al., 2017).
- Morus sp. (mulberry trees) (Sánchez-Salcedo et al., 2017).
- Parthenium hysterophorus (parthenium weed) (Kaur et al., 2017).

* The abbreviation BBCH derives from the first letters of the German names of Biologische Bundesanstalt (Federal Biological Research Centre), Bundessortenamt (Federal Plant Variety Office) and Chemical industry.
