Oil palm is the main plantation commodity in Indonesia. In the last two decades, Indonesian palm oil has always been associated with global warming because most of its plantation areas are located on peatlands and the cultivation method is considered not environmentally friendly. One of the problems of oil palm cultivation on peatlands is stem rot disease caused by the fungi Ganoderma sp. This disease is transmitted through root contact. There is no effective way to control this disease. Biological control is an alternative method that is environmentally friendly. This study aims to determine the effectiveness of acid-tolerant antagonists in controlling oil palm root necrotic on peat soils. The study tested 5 isolates of the acid-tolerant antagonists in reducing oil palm root necrosis caused by Ganoderma on peat soils in experimental gardens. The results showed that the acid-tolerant antagonists were effective in controlling root necrosis in oil palm seedlings on peat soils. Its effectiveness reached 16.67%. Differences in peat soil pH and peat maturity did not affect the effectiveness of root necrotic control caused by Ganoderma sp. These results indicate that using acid-tolerant antagonistic fungi can help reduce Ganoderma sp attacks on oil palms on peat soils.
