11th Meeting of the Panel on Efficacy Evaluation
of Herbicides and Plant Growth Regulators
The 11th Meeting of the Panel on Efficacy Evaluation of Herbicides and Plant Growth Regulators took place at EPPO Headquarters, in Paris, on 2004-05-11/12.
The Panel continued its main task of developing standards for conducting field trials to evaluate the efficacy of herbicides and plant growth regulators. A number of specific standards are in the process of revision: Regulation of growth in ornamental plants (PP 1/157) Regulation of growth in pome fruits (PP 1/158), Weeds in maize (PP 1/50), Weeds in potato (PP 1/51), Weeds in sugar and fodder beet (PP 1/52) and Weeds in sunflower (PP 1/63).
The Panel also discussed revision of the general standards on Effects on succeeding crops (PP 1/207) and Phytotoxicity assessment (PP 1/135). Considerable progress was made in preparing the draft standard on effects on adjacent crops.
The Panel will next meet in Greece (location still to be defined), on 2004-11-25/26
