Ornamental Fungicide

Astun Ornamental Fungicide provides preventative, and early curative activity on botrytis diseases of plants grown in commercial greenhouses and nurseries. Astun is most effective when used as a protectant fungicide and applied before the disease damages the crop. As a stand-alone SDHI (MOA Group 7) fungicide, it offers growers flexibility in tank mixing depending on the target disease complex. Astun is formulated in a user-friendly Suspension Concentrate (SC) formulation.
