Dry rot: It is the decomposition of felled timber caused by the action of various fungi. The fungus reduces fibers to a fine powder and the timber loses its strength. This disease is highly infectious and causes tremendous destruction.
It occurs when the timber is imperfectly seasoned and placed in a moist, warm confined atmosphere having no free access to air.
Fungus rapidly dies when exposed to air or sunlight. The best remedy is to cut away the affected part and paint the remaining part.
Upset: This defect occurs when timber is subjected to crushing or compression due to natural force.
Wet rot: This decomposition of sap occurs when timber is subjected to alternate wet and drying condition.
Foxiness: This defect appear in the form of discolouring due to overmaturity of tree.
Note:
Fungi that attack growing trees and continue to damage it in structures are known white or brown rot, white trunk rot, etc.
