Fusarium Wilt on Tomatoes

Description: 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.

Solution: Maintain 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 sell ground limestone. When fertilizing, use a slow-release organic source of nitrogen. Sprinkle SoilGard^TM 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.
