บทคัดย่อ (EN): Approximately 5% of rubber lands in Sri Lanka are infected with the white root disease attributing to low stand and yield. Disease incidence has increased at an alarming rate and hence an economically viable system is essential for the management. Although drenching systemic fungicides successfully controlled the disease in young rubber plants up to 3 years, infections on mature trees were difficult to manage similarly. Collar treatment did not eliminate the fungus from the bark tissues of mature laterals up to sixty days, whereas superficially grown fungus was never affected due to the same treatment. Addition of sulfur to soil in the lateral root zone was effective after four months in suppressing the superficially grown fungal rhizomorphs. Therefore, fungicide treatment integrated with sulfur application around infected trees was successful in managing further spread. In managing the infection in older plantations, fumigation of infected logs using metham sodium was effective in more than 50% of cases, while subsequently adding sulfur to soil enhanced the fumigation effect. Stump poisoning with 2,4-D had a significant effect on the decaying rate of logs in infected areas. For final verification about the viability of the pathogen in vacant holes in the infected area, application of Gliricidia poles was indicative. These integrated methods were effective in synergism in controlling or managing the spread of R. microporus in young and mature infected rubber fields.
