Effect of Ratoon Stunting Disease on the Yield and Components of Yield of Sugarcane under Rainfed Conditions
In a field trial conducted with eight varieties in the north coast area of Natal ratoon stunting disease (RSD) caused increasing lossesin yieldsof cane and sucrosefrom the plant to the second ratoon crop. All the varieties suffered losses in yield but the degree of loss differed markedly among the varieties. The total yield of sugar from the three crops was reduced by 38% in varieties NCo 376an...
متن کاملRatoon stunting disease of sugarcane: isolation of the causal bacterium.
A small coryneform bacterium was consistently isolated from sugarcane with ratoon stunting disease and shown to be the causal agent. A similar bacterium was isolated from Bermuda grass. Both strains multiplied in sugarcane and Bermuda grass, but the Bermuda grass strain did not incite the symptoms of ratoon stunting disease in sugarcane. Shoot growth in Bermuda grass was retarded by both strains.
متن کاملThe Effect of Ratoon Stunting Disease on the Yield of Some South African Sugarcane Varieties under Irrigated and Rainfed Conditions
The results of two field trials to determine the effect of ratoon stunting disease on the growth and yield of some widely grown and newly released sugarcane varieties are described. In the plant crop of a trial grown under full irrigation, the greatest reductions in yields of cane and sugar among six varieties, approximately 15%, occurred in N 14 and NC0376. In the first ratoon, the greatest re...
متن کاملSome Observations on the Bacterium Associated with Ratoon Stunting Disease of Sugarcane
The consistent association of a bacterium with ratoon stunting disease (RSD) has been confirmed in South Africa by phase contrast and electron microscope examination of sugarcane tissue diffusates from a wide range of varieties. The bacterium is rod shaped, often curved and measures approximately 1,O-4,O pm x 0,2-0,3 ym. Bacteria appear to be systemic within plants affected by RSD, but are most...
متن کاملThe Use of Tissue Blots to Screen for Varietal Resistance to Ratoon Stunting Disease of Sugarcane
No trials are currently conducted at SASEX to screen genotypes for resistance to ratoon stunting disease (RSD), a disease that is well established in most sugarcane growing regions of the world and considered to cause more yield losses worldwide than any other sugarcane disease. In South Africa, field trials have demonstrated that yield reductions under rainfed conditions can be as high as 40% ...
