Abstract

Developing an effective biocontrol consortium requires comprehensive assessment to ensure that the selected microbial combinations can provide both strong disease suppression and plant growth-promoting effects. This study aimed to evaluate the performance of four biocontrol consortia composed of indigenous microbes from Bantul Regency, Indonesia, in suppressing Fusarium basal rot (FBR) and promoting the growth of shallot (Allium cepa var. aggregatum) cv. Bauji. Three indigenous isolates were used: Trichoderma asperellum strain PBt1, Bacillus cereus strain PBt2, and B. cereus strain PBt3. Four consortia were formulated by combining two or three of these isolates, designated as Consortia A, B, C, and D. The biocontrol activity against Fusarium solani DRB-1 was evaluated for both single isolates and consortia. A greenhouse experiment was conducted using a Completely Randomized Design with two inoculation timings (before planting and early vegetative stage) and five replicates. The performance of each consortium was assessed based on FBR severity and shallot growth parameters. Results showed that Consortia B (T. asperellum PBt1 + B. cereus PBt3) applied before planting achieved the highest FBR reduction (34.8%) at 42 days after planting (DAP). Moreover, this consortium significantly enhanced shallot yield, as reflected by increased bulb weight and number. These findings suggest that Consortia B has strong potential to improve both FBR management efficacy and shallot productivity.

Abstract

Shallot cv. Tajuk is one of the most preferred shallot varieties to be cultivated, especially by farmers living in lowland areas with low water availability issues, such as Bantul and Kulon Progo. However, to date, the information about the resistance of this variety to Fusarium disease is poorly studied. Therefore, this study aims to investigate the prevalence of Fusarium disease in shallot cv. Tajuk is cultivated in Bantul and Kulon Progo. A survey of Fusarium disease occurrence was conducted in 8 shallot fields from 3 districts in Bantul (Imogiri, Sanden, and Kretek) and six shallot fields representing two districts of Kulon Progo (Lendah and Sentolo). Disease observation in Bantul was carried out during the dry season from June to August 2023, while the survey in Kulon Progo was performed during the rainy season from January to February 2024. The cropping system applied in each selected shallot field was also collected through the landowner interviews. Data obtained from disease monitoring were statistically analyzed using one-way analysis of variance (ANOVA), and significance among locations was subsequently analyzed using Duncan’s New Multiple Range Test with a p<0.05. Findings of this study revealed that the susceptibility of shallot cv. Tajuk to Fusarium disease varied between Bantul and Kulon Progo. Shallot var. Tajuk conferred higher resistance against Fusarium disease when it was cultivated in Kulon Progo. Results of this study also confirmed that different farming practices applied in each location appear to have a minor impact on the severity of this disease in the shallot cv. Tajuk
