A number of specific standards are in the process of revision: Regulation of growth in ornamental plants, Regulation of growth in pome fruit, Weeds in maize, Weeds in potato, Weeds in sugar and fodder beet, Weeds in sunflower and Weeds in brassica oil crops and most of them will be sent to countries for comment. 

Considerable progress was made in preparing the draft standard on effects on adjacent crops and in revising a general standard on Effects on succeeding crops (PP 1/207). Both standards will be further improved for the next meeting.

The Panel will next meet on 2004-11-24/25.
