Abstract

Dieback disease caused by Lasiodiplodia theobromae is an important disease on the nutmeg tree in Aceh Selatan. The disease has been widespread in the district. One alternative to control the disease is the use of antagonistic fungi from the nutmeg tree to inhibit the development of the cause of the disease. In vitro experiments were carried out by evaluating 4 types of antagonistic fungi from the nutmeg tree to L. theobromae. The aim of the study was to determine the potential of in situ soil fungus as an antagonistic agents against L. theobromae, the cause of dieback disease on the nutmeg tree in Aceh Selatan. Microbial isolation using serial dilution method. The fungus test which was successfully isolated as an antagonist candidate was carried out through the dual culture method. The results showed that four fungi namely; Trichoderma harzianum, T. virens, T. asperellum, and Talaromyces pinophilus have the potential as antagonistic agents against pathogens cause dieback disease on the nutmeg tree in Aceh Selatan, with inhibitory power ranging from 66-100% in vitro.

Abstract

Dieback disease caused by L. theobromae has destroyed nutmeg plantations in Aceh Selatan. Until now, effective control has not been found, while farmer continue to use pesticides that have a negative impact on the environment. Therefore, biological control is an alternative to environmentally friendly control that is being promoted. The purpose of this researth was to control dieback by inducing resistance using three spesies of Trichoderma (local isolates) from the Nutmeg. The three isolates were isolates of plant origin and the nutmeg seeds used are one year old. This researth used a randomized blok design with three species of Trichoderma (T. virens, T. asperellum, and T. harzianum), three doses (5, 10, 15 g), and three replicates.The variables observed were the incubation period, disease incidence, length of stem discoloration, height of the plant, and plant wet weight. Thr result showed that all species of Trichoderma tested were able to induce systemic resistance and promoted plant growth, by inhibiting the incubation period, disease incidence, length of discoloration, increasing height and weight of plant. The treatment of T. virens 10 g was the best treatment result compared to the others.
