چکیده

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.

Some 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...

A Large-scale Diagnostic Service for Ratoon Stunting Disease of Sugarcane

The Experiment Station has provided a diagnostic service for ratoon stunting disease (RSD), based on microscopic observation of the causal bacterium, since 1977. The service is widely used by growers to determine the extent of RSD in commercial cane fields and sources of seedcane, and it is also frequently used by Extension staff for survey purposes. The procedures used for diagnosing RSD are o...

Culturing Fastidious Prokaryotes—Points to Consider when Working with Citrus Huanglongbing or Greening

The fi rst of the fastidious prokaryotic plant pathogens to be grown in axenic culture was the phloem-limited Spiroplasma citri, which causes stubborn disease of citrus. Other fastidious prokaryotic plant pathogens followed and include Spiroplasma kunkelii (corn stunt) and Spiroplasma phoeniceum (periwinkle yellows). The vast majority of spiroplasmas are associated with arthropods and do not ca...

The 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% ...

Role of Gurdaspur Borer (bissetia Steniellus Hampson) in Sugarcane Ratoon Crop Failure and Its Integrated Control at Mardan

Gurdaspur borer causes great losses to sugarcane especially ratoon crop. On one way it damages the crop and on the other way its infestations paves way for certain diseases like red rot, stem rot and ratoon stunting disease. Experiments were conducted at Sugar Crops Research Institute, Mardan during 2003-2004 in sugarcane ratoon crops with the objective to see the effect of different control me...
