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.
Use a biofungicide containing the beneficial fungus Trichoderma harzianum, which works to suppress root pathogens. Apply it to newly sown seeds and transplants as a soil drench; can also be used on established plants. Avoid planting in poorly drained areas. We recommend Root Guardian™ Biofungicide for Soilborne Diseases. Maintaining soil pH at 6.5 to 7.0 helps. Test soil pH; if it is too acid, use Quik- Cal™ Pelletized Calcium to raise pH.
