In the last decade many new anti-sapstain products have been tested world-wide under laboratory and field conditions. Several extensive test programmes have been executed with different non-standardized test methods and procedures, with the result that the biological findings cannot be compared with each other. In this paper, gathered recommendations will be given in order to standardize test methods. These recommendations are based on questionnaires which have been sent to institutes throughout the world. For the realization of such a (standarized) test methodology, co-operation between test institutes, industry and working groups is necessary. This co-operation might also be useful for improving the treatment and application methods in the field. Standardization of sapstain methods is a challenge for Working Group II.
