Control methods of sesame bacterial wilt

First, the symptoms showed that sesame bacterial wilt occurred early, the root turned brown at the initial stage, the top of the plant drooped, and then dark green patches appeared on the stem, and gradually deepened and blackened. The leaves gradually drooped from top to bottom, the diseased plants were shorter than the healthy ones, the vascular bundles of the rhizomes turned brown, and finally the pith turned into holes. The bacterial liquid overflowed inside and outside the stem. The vascular bundles of the leaves were also damaged, and there were dark green spots on the veins. After the capsule is infected, it produces water-immersed spots, and gradually develops into dark brown, uneven spots. Second, there is no ideal control agent for sesame bacterial wilt, and agricultural control measures are often adopted, such as reasonable crop rotation, land leveling, rational fertilization and so on.
