decay before emergence and seedlings fall over at the soil line and
die. The disease causing fungi are common in garden soils. LIFE
CYCLE:
Overwinters in plant debris and can survive on seeds. Excessive
moisture encourages the disease. CONTROLS:Cultural: Plant seeds under temperature conditions that favor rapid germination, or pre-sprout seeds before planting outside. Water plants in the late morning to maximize drying conditions. Biological: Apply as a seed treatment (dust) and/or as a soil drench: Streptomyces griseoviridis (Mycostop); Burkholderia cepacia (Deny); or Gliocladium virens (Soilguard). Chemical: Use fungicide treated seed or apply sulfur as a seed treatment (dust) or soil drench. |
