Sugarcane white leaf disease (SCWL) is a major disease
of sugarcane production in Thailand, associated with phytoplasmas which transmitted to the plant by the leafhopper
Matsumuratettix hiroglyphicus (Matsumura) and Yamatotettix flavovittatus Matsumura (Hanboonsong et al., 2002;
2006). Phytoplasma infected sugarcane shows the white
leaf symptoms due to loss of chlorophyll. So far there is
no effective methods for controlling this disease. In order
to reduce or kill the phytoplasma pathogen, various treatments such as hot water, cold water and antibiotic have
been recommended for cane stock treatment before planting (Moutia and Dookun, 1999). However, the quantification of the amount of pathogen reduction from the cane
stalk after the treatments has not been studied. Therefore,
the objective of this study was to evaluate and compare
the efficiency of various treatments used for SCWL phytoplasma control and quantify the amount of SCWL phytoplasma pathogen after using different treatments.
