The diseased plants should be timely excavated and burned, and a new high fat film should be disinfected at the diseased point.
2. The symptoms of mosaic heart rot are white or yellow streaks that are either long or short, or narrow or wide, and form a mosaic with green parts, sometimes with diamond-shaped spots. Slack or cross-cutting of the pseudostem of the diseased plant showed that the leaf sheath collapsed and rotted, the heart and leaves died, and the heart rot occurred.
