<p>The herbicides contain cpds. of formula (I) (where R1 is H, lower alkyl or phenyl opt. substd. by X and/or NO2; R2 is alkyl, alkoxyalkyl, lower alkenyl, cycloalkyl, or phenyl opt. substd. by X and/or NO2; X is H, halogen or lower alkyl, alkenyl, alkoxy, alkylthio, alkylcarbonyl, alkylcarbonyloxy or haloalkyl; n = 1,2 or 3; m = (5-n)). (I) where R1 = H, R2 = Me, X = H and n = 1 are new cpds. Cpds. (I) also have microbicidal activity and can be used as fungicidal seed dressings.</p> |
