potato crop



Option is a fungicide for potato disease control.

Successful control of potato blight requires a season-long disease prevention policy that integrates cultural control measures and commencing the spray programme before blight infection.


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. 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.
