In oil palm plantations, the fungicide hexaconazole is used to control Ganoderma infection that threatens to destroy or compromisethe palm. The application of hexaconazole is usually through soil drenching, trunk injection, or a combination of these two methods. It is therefore important to have a method to determine the residual amount of hexaconazole in the field such as in samples of water, soil, and leaf to monitor the use and fate of the fungicide in oil palm plantations. This study on the behaviour of hexaconazole in oil palm agro-environment was carried out at the UKM-MPOB Research Station, Bangi Lama, Selangor. Three experimental plots in this estate with 7-year-old Dura x Pisifera (DxP) palms were selected for the field trial. One plot was sprayed with hexaconazole at the manufacturer's recommended dosage, one at double the recommended dosage, and the third plot was untreated control. Hexaconazole residues in the soil, leaf, and water were determined before and after fungicide treatment. Soil samples were randomly collected from three locations at different depths (0-50 cm) and soil collected fromthe same depth were bulked together. Soil, water, and palm leaf were collected at -1 (day before treatment), 0 (day of treatment), 1, 3, 7, 14, 21, 70, 90, and 120 days after treatment. Hexaconazole was detected in soil and oil palm leaf, but was not detected in water from the nearby stream.
在油棕种植园中,使用杀菌剂己唑醇来控制威胁破坏或损害油棕的灵芝感染。己唑醇的使用通常通过土壤淋洗、树干注射或这两种方法的组合进行。因此,重要的是要有一种方法来确定田间己唑醇的残留量,例如在水样、土样和叶样中,以监测油棕种植园中杀菌剂的使用和去向。这项关于己唑醇在油棕农业环境中的行为的研究是在 UKM-MPOB 研究站(雪兰莪州万津)进行的。该庄园的三个具有 7 年树龄的 Dura x Pisifera (DxP) 油棕的实验田被选为田间试验田。其中一个田块按照制造商的建议剂量喷洒了己唑醇,一个田块使用了建议剂量的两倍,第三个田块则是未处理的对照田块。在施药前后,测定了土壤、叶片和水中的己唑醇残留量。土壤样本是从不同深度(0-50 厘米)的三个位置随机采集的,从同一深度采集的土壤被混合在一起。在施药前一天(-1 天)、施药当天(0 天)、施药后第 1、3、7、14、21、70、90 和 120 天,采集了土壤、水和油棕叶片。己唑醇在土壤和油棕叶片中被检测到,但在附近溪流的水样中未被检测到。
