Abstract
The present invention relates to novel O,O-diaryl-1-acyloxy-2,2,2-trichloroethylphosphonates of the formula: wherein R is a C1-C8 alkyl, phenyl; X and Y are the same or different and are each selected from hydrogen, a C1-C8-alkyl, phenyl, a halogen, or X and Y together form a fragment of a benzene ring, m and n=1-2. The compounds possess a fungicidal activity and are incorporated in fungicidal compositions as active components. The fungicides according to the present invention are effective not only for prophylactic use, but for the treatment of already infected plants. The fungicidal compositions are also efficient in various agroclimatic conditions and provide a substantially longer period of fungicidal effect as compared to conventional fungicides.
