We are facing a problem of creating hole and converted it in to damaged leaves of coconut tree, images attached here. If you have any solution kindly suggest me?
CULTURAL CONTROL
The diseases occur on older leaves and are unlikely to reduce yields. Occasionally, they can be severe during long periods of wet weather, and/or where palms are growing in nutritionally poor soil. If control measures are warranted, improve nutrition and growing conditions. If spots occur in nurseries, and these are under shade, decrease shade levels.
RESISTANT VARIETIES
Malayan Dwarf and its hybrids may be more susceptible to brown leaf spot, but no studies have been carried out in Pacific island countries.
CHEMICAL CONTROL
Fungicides are unlikely to have any impact on these diseases given the minor damage they cause, the difficulty in applying them, their cost and their use is not recommended.
Swabs should be taken from the area of injury to confirm the type of infection, fungal or bacterial, and one of the systemic pesticides should be used
It could be due to fungal or bacterial damage. The main way of preventing disease is not letting irrigation wet the foliage and not using infected pruning tools :)
