18 Seedling Diseases Symptoms There are 3 types; Seed rot: Prevents the seed from germinating. Results in a thin sward. Pre-emergence damping off: Occurs post germination before emergence. Post-emergence damping off: Patches of rot at the stem base and collapse. May turn red, purple or yellow as the seedlings die. Susceptible grass species All grass species susceptible. Time of year Early spring and late autumn sowings most at risk. Climatic conditions Cool and wet. Turf conditions Wet soils, poorly prepared seedbed, inadequate or excessive seedbed fertiliser, excessive seedbed rates. Cultural: Good seedbed preparation using adequate drainage; appropriate use of seedbed fertiliser; appropriate seed rate, evenly sown to recommended depth; sow in favourable weather conditions into warm soil; oversow weak areas.
