Benefits
Option® contains cymoxanil, which is locally systemic and offers both preventative and curative control. It should only be applied in tank-mixture with specified formulations of partner blight materials (see compatibility appendix). The combination of two active ingredients will also help to reduce the selection and build-up of resistant strains of fungi. Potato fungicides may not give complete protection of blight when the incidence of the disease is severe.
