For root infection, see the treatment for brown root disease. Powdery mildew of rubber tree caused by Oidium heveae is an important disease of rubber plantations worldwide. Most of the major diseases of Hevea brasiliensis are of worldwide distribution (with the notable exception of South American leaf blight, against which strict quarantine regulations are enforced by rubber-growing countries outside the Americas to prevent the unauthorised import of Hevea) but their local severity and importance vary from one region to another. Apply a wound dressing compound in which Thiride 0.75% a.i is incorporated. In Nigeria, the most devastating diseases of rubber seedlings and budded plants in the nursery are the leaf diseases … SALB has been responsible for the failure of rubber plantations in South America and none of the Asian and African clones is tolerant to this disease. Bipolaris heveae), and (4) Corynespora leaf fall, caused by Corynespora cassiicola. is one of the most important leaf diseases in rubber tree (Hevea brasiliensis).However, physiological and molecular processes associated with the Hevea-powdery mildew interaction are still unclear.In this study, effects of powdery mildew infection on the mitochondrial and chloroplast functions in rubber tree were comprehensively investigated. However, root diseases, especially white root disease, will continue to pose a challenge during both mature and immature stages of rubber. Field experiments were carried out on Oidium control, for six successive years commencing from 1930, in the Matale District. The most important and widespread disease is P. pod rot and leaf fall, which causes serious defoliation in some material; striking resistance is occasionally found. Download this stock image: Oidium leaf disease Oidium heveae infection on rubber leaves Malaysia - AT9RCM from Alamy's library of millions of high resolution stock photos, illustrations and vectors. Hexaconazole 0.02% a.i (Contaf) is also effective. 3 Colonies of O. heveae on a rubber leaf. Oidium leaf fall (O. heveae), Colletotrichum leaf fall (C. gloeosporioides [Glomerella cingulata]), Phytophthora leaf fall (P. palmivora and P. botryosa), pink disease (Corticium salmonicolor) and stripe canker (P. Recent technology using unmanned aerial vehicle (UAV) has potential to provide cost effective data acquisition for the estimation of rubber leaf disease such as Oidium Disease. Oidium Leaf Disease is one of the most infected rubber leaf disease in Malaysia. The wintering (natural leaf shedding) of rubber is nature's way to help to renew and eliminate disease foliage. This method could improve rubber resistance breeding process. of the enough (Lim et al. Rubber diseas 1. The presentation is all about disease of rubber tree . Powdery mildew is a fungal disease that affects a wide range of plants. 3–5. A severe outbreak of this disease may cause an annual yield loss with 20% decrement of latex production in a rubber plantation. The rubber sector in Cameroon is faced with the effects of global economic crisis and a drop in the yield of latex due to several pests and diseases. Common Diseases of Rubber and their Management I. Foliar Diseases 1. Major leaf diseases of rubber are reviewed, such as: (1) secondary leaf fall caused by Oidium heveae and Colletotrichum gloeosporioides; (2) phytophthora abnormal leaf fall (Phytophthora botryosa); (3) birds eye spot (Drechslera heveae, syn. 4 Enlargement of 3. Abnormal leaf fall (ALF) disease caused by Phytophthora sp., powdery mildew (PM) caused Rubber - Hevea brasiliensis the important plantation crops in srilanka. Brown root disease cit.
