After several years in transition, the fungicidal seed treatment situation for corn is stabilizing. A majority of the seed planted this year will have been treated with Maxim XL, a combination of fludioxonil and mefenoxam. Alternatively, a few companies are using the CTS system, which is a combination of captan, metalaxyl, and a polymer coating. Both combinations include a broad-spectrum fungicide to control Fusarium, Rhizoctonia, and other fungi, along with a narrow-spectrum product to get better control of Pythium.
