BBCH Scales: Growth stages of mono-and dicotyledonous plants
EPPO recommends its members, particularly in relation to reports of field trials on plant protection products, to use the BBCH Scales for growth stages of crops and weeds. These have been published by Blackwell Wissenschaft, Berlin (DE) in 1997. No new edition has been published since, but an updated version the BBCH scales (edition 2001) is available from the BBA website. The BBCH scale is a system for a uniform numerical coding of phenologically similar growth stages of all mono- and dicotyledonous plant species. The BBCH scales can be downloaded as pdf files in German, English, French and Spanish, and cover the following plants:
Cereals, Rice, Maize
Oilseed rape, Faba bean, Sunflower
Citrus, Olive, Coffee, Banana
Soybean, Cotton, Peanuts
The use of this updated version is now recommended.
