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.
Before adding Astun to the spray tank, invert the container several times to mix the formulation. When filling the tank, slowly add the required amount of Astun. Keep the agitator running while filling and spraying.
Follow the label rates and timings for the product. The rate per 100 gallons is 8.5 to 21.8 fluid ounces.
