ABSTRACT:
The present invention concerns new 5-nitropyrimidine derivatives and their acid addition salts as well as compositions containing them and their use, for selective pre- and post-emergent combating of weeds and for diminishing the growth of lawn, cereals and suckers. The new 5-nitropyrimidines have the formula ##STR1## wherein R.sub.1 is alkyl with 2-7 carbon atoms, alkenyl or cycloalkyl; R.sub.2 is optionally substituted lower alkyl, alkoxy or alkylthio, alkenyloxy or alkenylthio, cycloalkoxy or cycloalkylthio; R.sub.3 is hydrogen, lower alkyl, haloalkyl, alkoxy, alkylthio or dialkylamino.
