The Effectiveness Colonized System of Ganoderma Vaccine Compared to Trichoderma on Oil Palm Plantations That Infected by Ganoderma boninense

Abstract

Basal stem rot caused by Ganoderma boninense causes fall and death of oil palm crops, and will drastically reduce plantation productivity by up to 50% and become one of the most serious problems in oil palm cultivation. This study aims to determine the effectiveness of the Colonized System of Ganoderma Vaccine (CHIPS®), as a biocontrol agent against the suppression of Ganoderma disease that infects oil palm trees in-field conditions. This research was conducted from early 2016 to the end of 2020 in a plantation located in Langkat area, North Sumatra by using 216 trees on 1 block as a sample experiment. Plants that infected with Ganoderma is treated with T1 treatment (MOAF™ & CHIPS®) shows the value of Disease Severity Index (DSI) decreasing to 37.50%, compare to T2 treatment (NPK Granular Fertilizer 13-6-27 & Trichoderma bio fungicides) which has DSI value of 100% in week 232 (in 2020) and C1 treatment (control) with the highest DSI value of 100% in week 212 (in 2020). The conclusions of this study shows that the treatment of T1 (MOAF™ & CHIPS®) is more successful in eradicating Ganoderma and have the highest profit ratio than any other treatments. The results of this study are useful as references for in-field inspection and large-scale production.
