Agrochemicals single isomer

Thus, native CDs and their derivatives are definitely established as a major group of chiral selectors in CE, CEKC, and MEKC. Perhaps, in the near future, the main emphasis will be directed to the use of a well-characterized, single isomer native and derivatized (neutral and charged) CDs as chiral selectors and to the use of chiral CE for solving problems in chemical, agrochemical, food, environmental, and, mainly, in... 

Some countries are already proposing active ingredient tax which will further lead manufacturers to develop single isomer agrochemicals where appropriate. At the present time, of the 150 or so agrochemicals listed in... 

Examples of single isomer agrochemicals are / -mecoprop, an important herbicide, and i, i ,5-deltamethrin, a neuroactive insecticide. 

A similar situation also pertains in the agrochemical industry, as many pesticides and other agrochemicals are chiral in nature. In 1981, Spencer [43] reported that out of 550 pesticides, 98% were synthetic in nature with 17 % chiral molecules and less than 8 % have been marketed as single isomers. Lewis et al. [44] also reported that 25 % of pesticides are chiral in nature. Recently, Vetter [45] reviewed the enantioselective fate of chiral chlorinated hydrocarbons and their metabolites in environmental samples. Not all of the aspects of chirality in the agrochemical industry have been fully explored yet, but investigations are under way. Therefore, knowledge about chirality in the agricultural industry is also very important.
