Regulation of the growth of plant life, including herbicidal, defoliant or desiccant effects, may be accomplished with certain 2,3-dihydro-1,4-dithiin 1,1,4,4-tetroxides of the formula ##STR1## wherein the R's have various values such as hydrogen, alkyl, etc. Certain of the compounds, such as 2,3-dihydro-5,6-dimethyl-1,4-dithiin 1,1,4,4-tetroxide, are new chemicals, and are useful as pre- and post-emergent herbicides, and in harvest aid procedures, such as defoliation/desiccation of various crops, including cotton and potatoes.
