The importance of set-aside in three countries of the Mediterranean basin (Italy, Spain and Greece) is discussed along with the influence of the type of set-aside on the species of weeds present in the succeeding sugar beet crops. Subsequently, for each country an analysis is made of the problems of weed management arising from CAP-oriented choices concerning soil tillage and the composition of crop rotations. The reduction of tilling depth, as an effect of the move towards extensive farming and towards a simplification of crop husbandry, has caused a modification of the weed flora present in sugar beet farms. Another aspect considered is the risk deriving from the use of persistent herbicides in crops that precede sugar beet in the rotation and which can be noxious to it, especially if associated with a reduced soil tillage. As a final effect of all of the modifications induced by set-aside and, more in general, by the simplification of crop husbandry, a new floristic pattern has emerged in sugar beet crops.
