1. Specific reasonsThis situation is mainly caused by being in a very dark environment for a long time and lack of light. Once this situation is discovered, it must be dealt with promptly. The quicker it is dealt with, the less harm it will cause. There are two ways to deal with it, depending on the severity. 2. Two different treatments(1) Small area: If the area of dryness and hole in the middle of the leaf is relatively small, you can apply some medicine on it, such as gentian violet. This way, it can be prevented from further decay. Then, you need to put it in a ventilated place. Don't spill water on it until its wounds have healed. Otherwise, not only will it fail to produce any effect, but more holes will appear. (2) Large area: However, if the hole is too large, the above measures will not work. At this time, in order to prevent them from further infecting other leaves, you can only cut off the leaves that have holes. Then, mash the garlic, add enough water and spray it on the leaves. In this way, it can play a disinfection role. If the situation is still serious, you can use carbendazim and other drugs. However, be careful not to use too high a concentration. 3. Joint treatment measuresAs we have said above, the reason for this phenomenon is the lack of light. So, no matter which of the above two types is chosen, sufficient light needs to be provided. If you raise it at home, you can put it on the balcony. This way, the light won't be too strong and still be effective. |
