| Summary: | This work describes an empirical analysis of an infected rubber tree by a selected known disease where its symptom could be detected visually from leaves gradual discoloration. It is known in this industry that diseases of rubber are divided into four categories; root, panel, stem and branch and leaf diseases. The most serious disease is the root disease because not only it can kill the tree slowly but it could spread from tree to tree by root contact. Among the major root diseases, white root is the most destructive agent of trees and agricultural crops especially Hevea brasiliensis. Since, it is too difficult and expensive to treating root disease infected trees; prevention is important whereby one must rely on symptoms appearing on the roots themselves in order to recognize the disease. Other symptom on the tree is when the leaves produce discoloration and go yellow and die. Conventionally, early detection of diseases is through assessing via visual inspection by an expert person regularly. However, this evaluation process however, are time consuming, low percentage in accuracy and as well as costly |
