The status of sugarcane smut and rust diseases and their control in the Caribbean
The advent of smut and rust diseases of sugar cane during the last six years into the Caribbean sugar industries posed serious threats to their viability. Smut is present in all and rust in all but two of the 22 industries. Smut was usually first observed on the very highly susceptible variety, HJ5741, and in other industries in its absence on B49119, L60-14, NCo310 and B42231. Rust was most often found on B4362, and spread throught the region very much more rapidly than smut. The progress of control of the diseases is outlined and dates for achieving complete control are given. Control measures are discussed with emphasis on the management of the epidemics so as to minimize economic loss. Management practices were based on eventual control by replacement of susceptible varieties with interim containment of infection levels and of losses. Losses to smut were mostly due to replacement of high yielding varieties with older less prolific ones, and to direct losses resulting from the infection. Losses to rust were mostly direct. The variety situation in the region is consiered to be generally unsatisfactory. The susceptibility rating procedures used in the region are described. Variety selection and attendant necessary quarantine facilities are advised especially in light of increasing incidence of dangerous diseases
