Managing the ganoderma basal stem rot in oil palm plantation through sanitation and fungicidal treatment

Recommended management during replanting is removal or destruction of the palms involving pushing over of the old stand shredding into small fragments excavating all roots and stumps by digging a 1.5m x 1.5m x 1.5m pit ploughing the replanting areas and planting new palms away from former planting points in the inter-row to minimise infection through root contact with infected debris.

Abstract

The threat of Ganoderma the causal agent of basal stem rot BSR disease to the oil palm industry in Malaysia warrants new and more aggressive approaches in finding solution to this disease. The situation is made more critical with the active replanting of second-generation oil palm that is currently being carried out in some plantations including areas with bad history of Ganoderma. For the control of Ganoderma in existing stand the use of the hand-knock pressure injection for application of fungicides was investigated. The development of the hand-knock pressure injection is seen as another breakthrough that will make fungicidal treatment of infected palms possible. With this technique fungicides could be applied precisely to the infected sites ensuring better delivery of the chemical with minimal wastage. Studies have showed that the application of hexaconazole with hand-knock pressure injection had limited the spread of Ganoderma infection within the infected standing palms. After 5 years 70 of diseased palms treated with hexaconazole dissolved in 10 liters of water applied using hand-knock pressure injection were still living and producing fruit bunches but none from untreated palms. Fungicidal treatments can improve oil palm productivity by prolonging the life of the Ganoderma-infected palm. Field evaluation of the efficacy of sanitation at the time of replanting oil palm had indicated that excavation of the stumps and roots of the old palm followed by ploughing and rotavating the areas can reduce the incidence of BSR disease on replanted palms by 13 in comparison with non-excavated and non-ploughed areas ten years after planting. Recommended management during replanting is removal or destruction of the palms involving pushing over of the old stand shredding into small fragments excavating all roots and stumps by digging a 1.5m x 1.5m x 1.5m pit ploughing the replanting areas and planting new palms away from former planting points in the inter-row to minimise infection through root contact with infected debris. By practising this method BSR incidence on replanted palms can be significantly reduced.
