Abstract

Palm oil production in Riau is increase by the year. The increase in palm oil production still has obstacles caused by pests and diseases, among others caused by pathogenic fungi, Ganoderma boninense, this fungus causes root rot disease. Control of stem rot disease is needed appropriate techniques, especially controls that are environmentally friendly. One of the uses of biological agents, such as Trichoderma, especially Trichoderma virens. This study aim to obtain a dose of Trichoderma virens in controlling Ganoderma boninense in oil palm pre nursery in peat medium. This research was conducted at the experimental field of the Faculty of Agriculture and Animal Husbandry of the State Islamic University of Sultan Syarif Kasim Riau. This research was conducted on December 2018 - March 2019. This research was designed by Complete Randomized Design (CRD) by conducting Trichoderma virens test on Elais guinensis Jacq seeds with various doses where each treatment was repeated 6 times there are 30 experimental units. The observed parameters were macroscopic and microscopic fungi, in-vitro test, speed of infection, intensity of disease attack, plant height, stem diameter and rot ratio. The results showed that Trichoderma virens fungi can reduce the intensity of fungal disease of attack Ganoderma boninense given Trichoderma virens increased the growth of stem diameter of Elais guinensis Jacq seedlings.
