Effects of FD141 and its analogs on the germination and morphology of selected plant pathogenic fungi

A USDA experimental natural product fungicide referred to as FD141, and seven of its chemical analogs plus seven commercially available fungicides were evaluated for their ability to inhibit fungal germination. Botrytis cinerea, Colletotrichum acutatum, C. fragariae, C. gloeosporioides, Phomopsis ob...

Summary:A USDA experimental natural product fungicide referred to as FD141, and seven of its chemical analogs plus seven commercially available fungicides were evaluated for their ability to inhibit fungal germination. Botrytis cinerea, Colletotrichum acutatum, C. fragariae, C. gloeosporioides, Phomopsis obscurans, and P. viticola were used for this purpose. FD141 and the commercially available fungicides were effective germination inhibitors, while most FD141 analogs were less effective. However, one of the experimental analogs, FD142, caused anomalous development in germ tubes of three of the six fungi.
