Abstract: | A series of substituted 2,2′-bipyridine derivatives was prepared using the Kröhnke reaction and alkylation of 4,4′-dimethyl-2,2′-bipyridine. These compounds were screened for fungicidal activity against 9 plant diseases. 5-Phenyl-2,2′-bipyridine exhibited strong preventative and curative fungicidal activity against wheat powdery mildew (Erisyphe graminis) and wheat leaf rust (Puccinia recondita). |
