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.
植物生长的调节,包括除草、落叶剂或干燥剂效果,可以通过某些2,3-二氢-1,4-二
硫杂环[4.5.3]二氧杂环[2.3.0]
辛烷-1,1,4,4-四氧化物来实现,其
化学式为##STR1##其中R的值可以是氢、烷基等不同的取值。其中某些化合物,例如2,3-二氢-5,6-二甲基-1,4-二
硫杂环[4.5.3]二氧杂环[2.3.0]
辛烷-1,1,4,4-四氧化物是新的
化学物质,可用作种前和种后
除草剂,在收获辅助程序中,例如棉花和马铃薯的落叶/干燥。
