    摘要: New tetrahydro-1,3-oxazines of the formula ##STR1## where R denotes linear or branched haloalkyl of up to 3 carbon atoms, R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are identical or different and each denotes hydrogen or linear or branched alkyl of up to 3 carbon atoms, R.sup.6 denotes hydrogen or linear or branched alkyl of up to 8 carbon atoms, R.sup.7 denotes hyrogen, linear or branched alkyl of up to 8 carbon atoms, alkoxyalkyl of up to 6 carbon atoms or dialkoxyalkyl of up to 8 carbon atoms, and R.sup.6 and R.sup.7 may together form a methylene chain of 4 or 5 carbon atoms.The compounds are antagonistic agents and, as such, increase the tolerance of herbicidal acetanilides by crop plants. Herbicidal agents containing the tetrahydro-1,3-oxazines in combination with haloacetanilides are suitable for combating unwanted plant growth in Indian corn and cereal crops.
