Imidazole Chemistry in Crop Protection

An overview is given of the significance of the imidazole scaffold in crop protection chemistry.The main herbicidally, fungicidally and insecticidally active imidazole classes are presented, together with their synthesis routes, modes of action and biological efficacies.Also, partially and fully saturated imidazole derivatives, such as imidazolines and imidazolidines, oxygenated derivatives, such as imidazolinones and hydantoins as well as annulated derivatives, such as benzimidazoles, are covered.In addition, also the role of imidazoles as intermediates or reagents in the synthesis of other agrochemicals is reported.
