Rhinoceros beetle, also known as Komban Chellu (Malayalam), Komban Poochi (Tamil), Kombina Hula (Kannada), Gandam Purugu (Telugu), and Genda Keeda (Hindi), is one of the most destructive pests affecting coconut trees. It mainly attacks the crown region and damages newly emerging leaves, leading to weak growth and reduced yield.
This problem often starts when saplings are not properly maintained. With simple care and timely action, it can be effectively controlled.
- Damaged or cut central shoot
- Holes in unopened leaves
- Broken or weakened crown
- Slow or stunted growth
Coconut saplings are highly vulnerable to pest attacks. When regular care is ignored, beetle infestation becomes more likely and growth is affected. Maintaining cleanliness and monitoring the crown area from the early stages ensures healthy development of the tree.
Proper cleaning is the most important step in controlling rhinoceros beetle. The crown region must always be clean and free from debris. Dried leaves, organic waste, and decaying matter should be removed regularly, as they attract beetles.
If the tree is already affected, all damaged parts of the crown should be cut and removed completely. Infected leaves must be trimmed neatly, and the top portion should be cleaned thoroughly to restore the tree structure.
Materials Required:
- M-sand or fine sand
- Ant powder
Preparation:
- Mix sand and ant powder thoroughly
- Use gloves while handling
- Store remaining powder in an airtight container
- Apply the mixture inside leaf axils and crown
- Ensure it fills all gaps properly
- Slightly shake the tree for even distribution
✔ Provides protection for up to 6 months
Applying this from the sapling stage helps prevent future infestation effectively.
During dry periods, mix 50 grams of ant powder in 1 liter of water and pour it into the crown and leaf axils.
Alternatively, insecticides like “Jump” can be mixed with water and sprayed on the crown and growing point for added protection.
- Apply lime once every 3 months
- Maintains proper soil pH
- Supports better growth and pest resistance
