• Fusarium wilt usually causes the lower leaves on one side of the plant to turn yellow.
• Infected plants usually are stunted and wilted as the organism develops in the food and water conducting tissues.
• Brick red tissue can be observed in the stem when it is split lengthwise.

Fungal and viral diseases can be reduced by:

• Treating high quality seed with fungicides labeled for cowpeas.
• A four or five year rotation with other crops.
• In addition to the cultural practices listed above, bury previous crop debris and the sclerotia, to control Southern blight at least 6 inch deep as far ahead of planting as possible.
• Seeding into warm, well-prepared soils.
• Planting certified seed of resistant varieties.
• Controlling weeds.
• The removal of virus-affected plants.
• Spray any one of the systemic insecticide like to control the vector.
• When resistant varieties are not used, it is important that root-knot nematode control practices be followed since nematodes increase plant susceptibility to Fusarium wilt.
