Fusarium Crown Rot

Fusarium oxysporum f. sp. radicis-lycopersici

Note: Click on the image(s) above to see larger version.

Symptoms:
Plants infected with crown rot are stunted and yellow. Symptoms begin on older leaves and progress to the entire plant. The entire plant eventually turns brown and dies. The roots are brown and may rot away due to secondary pathogens. The stems often have brown vascular streaks and dark brown lesions often occur on the stem near the soil line.

Control:
Infection enters the plant through wounds, but it may also be seed born. Disease development is faster in cool wet soils, and the problem is often severe in greenhouse crops. Fungicide drenches may be effective in the greenhouse situation.
