"Seed treatments today generally contain three different active ingredients, sometimes four, with different modes of action and it's the seed treatments that contain Group 4 active ingredient, they're more effective against these water moulds, against pythium and phytophthora. If that group was not represented in the seed treatment you're using, you may be at a little bit more of a disadvantage," he said. "Seed treatments of course can only protect plants for a limited amount of time and that's generally a maximum of three weeks post planting."
Kaminski notes the longer plants are under water the less likely it is that a fungicide seed protectant can actually protect the seed.
