WebSep 12, 2000 · Treatment with phenylpyrroles was shown to considerably increase the content of polyols, especially glycerol, in the fungal mycelium (Pillonel and Meyer, 1997) (Fig. 4). Furthermore, a protein kinase, which may be involved in the regulation of glycerol biosynthesis was shown to be inhibited by phenylpyrroles. WebPhenylpyrroles are a new class of non-systemic fungicides developed by Ciba-Geigy. They are closely related to the natural antibiotic pyrrolnitrin. As a seed treatment, the phenylpyrroles fenpiclonil (20 g a.i./100 kg seed) and CGA 173506 (5 g a.i./100 kg) are very well tolerated and control the major seed-borne pathogens of wheat, rye ...
