Pioneer® brand soybean varieties are rated for field emergence, which is based on speed and strength of emergence in sub-optimal temperatures.
Just-emerged soybean plants damaged by frost. The cotyledons are still green and look healthy, but the region of the hypocotyl just below the cotyledonary node is turning brown and is becoming soft and shrunken.
Soybean seedlings with damping off symptoms due to Pythium seedling blight, a soil-borne fungal pathogen that is favored by wet soil conditions and cool temperatures just after planting. Damping-off occurs when germinating seedlings are infected prior to or just after emergence. Diseased seedlings collapse when the infection girdles the hypocotyl.
