EPA chemical information	Information provided by: ofmpub.epa.gov (external link)
use	ethiol is a systemic fungicide, which can prevent powdery mildew of cereals. When used as a seed dressing agent, it is inhaled through the roots to protect the whole plant; such as spraying on the leaves, it is absorbed and conducted by the leaves to prevent the spread of the disease. Ethrophenol is a systemic fungicide, which can prevent powdery mildew in cereals. When used as a seed dressing agent, it is inhaled through the roots to protect the whole plant; such as spraying on the leaves, it is absorbed and conducted by the leaves to prevent the spread of the disease.
