Aims: To examine the interaction of diagnostic techniques, initial titres of Leifsonia xyli subsp. xyli (Lxx), sugarcane genotype and thermotherapy on ratoon stunt (RSD) control.
Methods And Results: Single buds of RB867515, RB92579 and RB966928 were submitted to 50°C/2 h or 52°C/30 min under factorial block design and five replications; results were checked 9 months later by serological (DBI) and molecular (PCR) techniques.
