Use of N-alkyl glucamides in order to reduce the drift in the application of plant treatment compositions containing glufosinate

The invention relates is the use of one or more N-alkyl glucamides of formula (I) where R1 is a linear or branched alkyl group having 5 to 9 carbon atoms, and R2 represents an alkyl group having 1 to 3 carbon atoms, in order to reduce the drift in the application of plant treatment compositions, containing at least glufosinate as an agrochemical active ingredient.
