ABSTRACT:
Substituted 2,3-dihydro-1,4-oxathiins of the formula ##SPC1##
Display useful plant growth regulant effects including herbicidal effects. Examples are 2,3-dihydro-5,6-diphenyl-1,4-oxathiin, and 2,3-dihydro-5-(4-methyl-phenyl)-6-phenyl-1,4-oxathiin 4-oxide. The compounds are useful for the selective control of grasses and as dwarfing agents, as well as for inhibition of vegetative and reproductive axillary growth, and for increasing the sugar content of sugar producing species. A number of these are new compounds.
