An SRA research project is progressing technology with the aim of quantifying Ratoon Stunting Disease (RSD) in every rake of cane that enters a mill. This could revolutionise the industry’s understanding of the distribution of this bacterial disease which is difficult to diagnose due to the lack of visible symptoms.
Research is developing a Near Infrared (NIR) tool which involves collecting NIR data, confirming it by molecular data, and then developing NIR calibrations which will indicate not only if mill juice does or does not have RSD present but also the potential severity of RSD within a milling area.
This information will help growers decide whether to replant or ratoon in the following season and to increase adoption of SRA’s recommended management guidelines for effective long-term control of the disease.
The project is being led by SRA Lead Field Pathologist, Dr Seona Casonato (pictured above).
