| Since sugarcane bacilliform virus (SCBV) was first reported in Mauritius in 1989, it has been found to be widely distributed although its impact on yield and in the decline of varieties has not yet been substantiated. The most sensitive method of detection was by immunoelectron microscopy whereas direct ELISA was only effective when the virus was present in high concentration. Using these two methods, it was observed that all the 127 noble canes in a connection, as well as unreleased clones and 13 commercial varieties, were infected. The virus has also been intercepted in quarantine in clones imported from six countries. Wild sugarcane (Saccharum robustum, S. spontaneum) and the grass Panicum maximum have been found to be naturally infected. In sugarcane, the virus has been detected in all plant parts with the highest concentration of particles in the first unrolled leaf (especially in the middle part) followed by the root tissue, stem and axillary bud. The virus has not been found in true seed. The concentration of SCBV appears to fluctuate, increasing in December to reach a peak in February, which coincides with the period of active growth and high temperature, to decrease as from June. The effect of SCBV on yield could not be determined as a few particles of the virus were eventually detected in the healthy control in first ratoon, presumably because the virus was present in very low concentration at the beginning of the experiment. Control of the virus by heat treatment, bud culture and meristem culture has proved unsuccessful. Incorporation of an antiviral compound in tissue culture is being investigated. | |
