Do not spray during blossom time. Leaves are stippled and yellowish. They have a dirty appearance, dry out and drop. Small webs may be visible. Spray Malathion when damage first appears and repeat at weekly intervals until damage no longer occurs.
Outer leaves turn dark brown along margins and between the veins.
Plants are stunted. Fungus enters through the roots and plugs water-conducting vessels. Use only varieties resistant to this wilt. Flowers and buds are distorted. Fruit may be irregularly shaped and catfaced.
