Symptoms: The first symptom is yellowing of older leaves, then bright yellowing from top to bottom of plant, often affecting only one branch of plant. Sometimes leaves droop and curve downward. Plants often wilt and die.

Solutions: Use Trichoderma harzianum as a soil drench to suppress root pathogens on newly sown seeds, transplants and established plants. 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. Follow up with foliar sprays of a harpin protein-based product every 7-10 days. We recommend Green Guard™ Plant Growth Enhancer.
