Slow growth and appearance of red spots or streaks on lower stem and roots. First true leaves prematurely yellow and drop off. Diseased plants often stay alive by producing new roots near the soil surface but yield is severely reduced or eliminated.
Avoid compacting soil. The beneficial fungus Trichoderma harzianum, included in some biofungicides, works to suppress root pathogens. Use as a soil drench on seedlings, transplants and established plants. We recommend Root Guardian™ Biofungicide for Soilborne Diseases.
