An overview is given of the significance of pyrazole derivatives in crop protection chemistry. The main herbicidally, fungicidally and insecticidally active pyrazole classes are presented, together with their synthetic routes, their modes-of-action and their biological efficacies. Indazoles and other bicyclic pyrazole derivatives are also covered.
