The global agrochemical market is predicted to reach $223 billion in 2015. The market is driven by rising population, declining availability of land suitable for growing crops and agrochemical use in biofuel production. Pesticide classes – such as insecticides, herbicides and fungicides – are main products of the industry. Exposure to pesticides is monitored to reduce potential health, economic and environmental risks. Furthermore, since a number of pesticides are chiral, their enantiomers may have different impact on the environment. Enantioselective chromatography is best suited for effective separations of chiral pesticides.
It is estimated that about 30% of pesticides are chiral. Isomers of chiral pesticides may differ in activity and toxicity; therefore, availability of isolated pesticide isomers is of significant importance to study their occurrences and fate in the environment. It is known that one isomer of the herbicide dichlorprop, widely applied to kill weeds, is its active ingredient, while the other isomer is inactive. Using only the active ingredient of dichlorprop will prevent environmental pollution by the unnecessary isomer.
Enantioselectivity of chiral stationary phases toward a variety of pesticides can be used to separate their isomers for occurrence, fate and effect studies.
