A: Disease characterized by wilting of plant, without definite leaf spots; with or without spotting or decay of fruit.
(a) Yellowing, wilting, and death of the leaves from the base upward, followed by wilting and usually a gradual death of the plant. Single shoots often killed before serious infection of others. Dark-brown discoloration of woody tissues just below the green outer cortex of stem. No soft decay of stem. No spotting of fruits, but sometimes discoloration of the water conducting vessels. Symptoms may be apparent on only one side of the plant but not limited too.....................................................................................Fusarium wilt
(b) Yellowing, wilting, and loss of foliage, confined largely to the bases of shoots. Plants wilt during the day often recovering in the evening or morning. All branches affected uniformly. Plants stunted but usually survive the season. Discoloration of the woody tissues of the stem, generally confined to the lower part of the plant. No soft decay of stem and no spotting of fruits.
.....................................................................................Verticillium wilt
(c) Rapid wilting of the entire plant without yellowing of the leaves. Dark water-soaked decay of central portion of the stem just above the ground line, followed by death of the plant. No spotting of the fruits.
.....................................................................................Bacterial wilt
(d) Wilting and upward rolling of margins of leaflets; usually only on one side of leaf affected first. Leaves browning, withering, and dying but remain attached to the stem. Dying of leaves progressing up the stem; one side of the plant often attacked first. Stems may have open cankers and yellowish, mealy decay of inner tissues. "Bird's-eye" spotting of the fruit; spots 1/8" to 1/4" in diameter; small cavities in central portion of the fruits.
....................................................................................Bacterial canker
(e) Gradual drooping and eventual dying of the leaves over the entire plant without marked yellowing of the foliage. Stem decayed at ground line and covered with a whitish fungus growth, with small, light-brown sclerotia. Fruits on ground often destroyed by the fungus.
....................................................................................Southern wilt/blight
(f) Slow wilting and eventual death of the plant; soft tissues of the stem decayed, with cavities that contain a grayish-white fungus growth and large, black sclerotia. Fruits sometimes show a watery soft rot.
....................................................................................Stem rot
(g) Emergence failure or collapse and wilting of seedlings plants caused by a decay of the stem at the ground line or roots.
