A Wilt Disease of the Oil Palm

  title={A Wilt Disease of the Oil Palm},
  author={Claude W. Wardlaw},
DURING recent investigations in the Belgian Congo I came across what is apparently a hitherto undescribed wilt disease of the oil palm (Elaeis guineensis). Palms of 4–20 years of age have been seen with characteristic necrotic symptoms in the vascular strands of the trunk and roots. The destruction of well-grown palms has been observed in widely separated areas. The lower leaves of such palms show characteristic flagging and wilting; they eventually break near the base of the petiole and hang… 
Vascular Wilt Disease of Oil Palms in Nigeria
In an inspection of oil palm plantations in Nigeria, in the present year, the presence of vascular wilt disease is obtained, some plantation areas show how severe this disease can be, many 8–12 years old palms being killed off, together with the younger replacements.
Experimental Evidence of the Pathogencity of Fusarium oxysporum Schl. f. to the Oil Palm (Elæs guineensis J.)
IN 1946 and 1948 Wardlaw1 reported the widespread occurrence of a vascular wilt disease of the oil palm in the Belgian Congo and Nigeria, closely comparable strains of Fusarium oxysporum Schl. f.
Notes on two strains of Fusarium oxysporum from the oil palm in the Belgian Congo
Two strains of Fusarium oxysporum were isolated from leaves and from diseased vascular strands of the oil palm in the Belgian Congo and differences were observed in pigmentation, in zonation when exposed to light, in the amount and appearance of mycelium, and in sporulation.
Fusarium oxysporum var. redolens from Africa as a cause of vascular wilt disease of oil palm
The vascular wilt disease of oil palm (Elaeis guineensis Jacq.) was first reported by Wardlaw in Zaire (1946a, b). Since then, the disease has been reported in other parts of Africa. So far, Fusarium
Control Approaches against Vascular Wilt Disease of Elaeis guineensis Jacq. Caused by Fusarium oxysporum f. sp. elaeidis.
The present review outlines the importance of oil palm and the various approaches to fight against vascular wilt disease, with emphasis on biological control by the use of resistant plant material.
The role of phenolic compounds in the determination of wilt disease tolerance of oil palm (Elaeis guineensis JACQ)
Principal Component Analysis (PCA) and Discriminant Analysis (DA) show that although the phenolic metabolism was different in both organs; all the phenols belonged to the flavonoids and can be used to distinguish the tolerant clones and sensitive ones.
Observations on strains of Fusarium oxysporum from the oil palm and banana from Central and West Africa
St strains of Fusarium oxysporum isolated from the necrosed vasculai strands of the oil palm from West and Central Africa and from banana wilt disease in the Cameroons may not be the only pathogenic species associated with palm wilt Disease.
Diseases of the Oil Palm
Abstract Thirty two diseases and disorders affecting the oil palm in Africa, Southeast Asia and South America are described with their distribution, economic importance, etiology and control. Of
Fusarium oxysporum schl, f. as the cause of vascular wilt disease of the oil palm (Elaeis guineensis)
In inoculation experiments, which are described in detail, Fusarium oxysporum Schi. f. isolated from the necrosed vessels of a typically wilted oil palm, has caused root disease and vascular
An Investigation of Pathogenicity of four Isolates of Fusarium oxysporum from South America, Africa and Malaysia to Clonal Oil Palm
The pathogenicity of four isolates of Fusarium oxysporum from Brazil, Zaire and Malaysia, to clonal oil palm (Elaeis guineensis) was examined. The isolates from Brazil and Zaire were virulent
