Methods of preventing and controlling flower heart borer

1. Plug the wormhole with Vaseline oil, resulting in poor ventilation and suffocating the moth in the wormhole.

2. Stick the wire into the wormhole and stab the moth to death. The tip of the wire is bent back into a hook to hook the worm out. If the worm is stabbed, there will be water slurry on the wire head.

3. Insert a cotton ball soaked with dichlorvos into the wormhole, and the hole is closed with clay or Vaseline, and the moth can be killed.

4. Inject pure alcohol into the wormhole to seep into the branches and kill the worm.

5. the eggs of the borer lay on the young stem, and after hatching, they become green worms, crawl along the stem and decay into the stem, so the repellent is spread as early as possible during its crawling period, especially when plants sprout and form shoots in early spring.

6. The branches that have been decayed into the larvae should be cut off together with the worm body from about 2 inches under the hole.
