What are the symptoms of bacterial wilt in sesame?

(Agricultural Wealth Network) In the early stage of the disease, dark green patches appear on the stem, which later turn darker and black, forming streak-like lesions. The top of the stem of affected plants wilts during the day and recovers at night. Soon afterward, the plants die. Affected plants are shorter than healthy plants, the roots turn brown and rot, and the stems become hollow. Bacterial ooze exudes from inside and outside the stem, gradually forming black shiny grains. After the leaves are affected, the veins show dark green streaks, sometimes crisscrossing in a net-like pattern, translucent when held against the light, with oily-looking centers. On the underside of the leaves, the veins become yellow and raised, extending in a wavy pattern toward the leaf margin, forming wavy twists. Affected capsules show water-soaked lesions, gradually becoming brown streaks of uneven thickness and shriveling. Seeds are shrunken and empty, dirty brown, and unable to germinate.
