Abstract

Basal stem rot of oil palm induced by Ganoderma boninense is a major economically important fungus that has incurred great losses to the oil palm industry. It has triggered desire for many researchers to find solutions through biological chemical and physical controls as well as using plant activators to carry out proper disease management strategies. At present nutrients could conceivably be supplied by soil application with a view to control the disease in addition to them being used as fertilisers. Therefore the objective of this study was to investigate the effect of Ca Cu and Salicylic acid against G. boninense. In vitro application of nutrients was tested by poison and dipping test for their resistance towards G. boninense. There were four different concentrations for each nutrients and 0 ppm serve as a control. Only combination of calcium chloride salicylic acid and calcium chloride copper-EDTA salicylic acid showed inhibitory effect more than 50 for the highest concentration in poison media test. On the other hand for dipping test salicylic acid calcium chloride salicylic acid copper-EDTA salicylic acid and calcium chloride copper-EDTA salicylic acid showed percentage inhibition of radial growth PIRG values greater than 50 for all concentrations. There was a Significant difference at inhibitory effect at p0.05 for salicylic acid but there were no significant differences for rest of above combination and its concentration. The highest efficacy of control was achieved by combination of calcium chloride salicylic acid by an average of 91.25 94.38 97.50 and 100.00 for concentration of 500 50 1000 100 1500 150 2000 200 ppm respectively and followed by combination of calcium chloride copper-EDTA salicylic acid by means of 100.00 100 79.38 68.75 for concentration 500 50 50 1000 100 100 1500 150 150 and 2000 200 200 ppm respectively. The result implied that the level of inhibition by those combining nutrients will be provided the use as a potential fertilizer to control destructive pathogen of G. boninense in oil palm plantations. Consequences of the in vitro study are a useful reference foundation for further tests in the field and large scale production trials.
