Rot (Damping-Off, Stem Rot) on Tomatoes
Description: Damping-off occurs at or before germination,
causing rapid decline and death of seeds or young seedlings.
On older plants, disease causes severe wilting and black
stem, beginning at ground level, resulting in severe
stunting or death of plants.
soil pH at 6.5 to 7.0. Test soil pH; if it is too acid,
use ground limestone to raise pH. Most garden centers
and farm stores sell ground limestone. When fertilizing,
use a slow-release organic source of nitrogen. Avoid
planting in poorly drained areas. Sprinkle SoilGardTM Microbial
Fungicide over seed at time of sowing, BEFORE
covering seed with soil. When starting seed indoors,
mix SoilGard with potting soil before seed is sown.
