Fludioxonil is a synthetic compound of the phenylpyrrole group of substances. It can be used to control fungal disease, making it a useful seed treatment as well as a post-harvest treatment for fruit. Fludioxonil is a broad-spectrum fungicide which is non-systemic with a long residual activity. he mode of action of fludioxonil is the inhibition of transport-associated phosphorylation of glucose as well as preventing glycerol synthesis. Being broad spectrum fludioxonil is effective against most major seed diseases, including Seedling blight, Stem-Base Browning, Snow Mould and Common Bunt. In post-harvest situations it is effective against Grey mould, Black Spot, storage rot and Powdery Mildew. In combination with thiamethoxam and metalaxyl-M, fludioxonil also acts as an insecticide seed treatment, effectively preventing peach-potato aphid, flea beetle and cabbage stem flea beetle.
