Identification
Common NameMetrafenone
ClassSmall Molecule
DescriptionA member of the class of benzophenones that is benzophenone in which one of the phenyl groups is substituted by methoxy groups at positions 2, 3, and 4 and by a methyl group at position 6, while the other is substituted at positions 2, 3, and 6 by methyl, bromine, and methoxy groups, respectively. A fungicide with protectant and curative properties, it is used for the control of powdery mildew in cereals and grape vines.
