Post planting fungicide application to reduce losses to damping-off fungi may be detrimental

There is seed and seedling loss which occurs between seed-sowing and the time the seedling is established in the seedbeds due to a group of fungi collectively known as "damping-off" fungi. These fungi (of the genera Pythium, Corticium, Fusarium, Rhizoctonia, Cylindrocladium) are generally most destructive under moist conditions like those in seedbeds, and are generally found in nursery soils. "Damping-off" in general is divided into two phases; pre-emergence and post-emergence. These terms indicate infection and killing of seeds and/or seedlings before they emerge from the soil and shortly after they emerge from the soil (and generally before they become woody) .
