Abstract. Nurbailis, Yanti Y, Resti Z, Djamaan A, Rahayu SD. 2023. Consortia of endophytic bacteria for controlling Colletotrichum gloeosporiodes causing anthracnose disease in chili plant. Biodiversitas 24: 3503-3511. Anthracnose disease caused by Colletotrichum gloeosporioides is the main disease in chili plants, which reduces yields by up to 90%. Using a consortium of endophytic bacteria is an alternative way to control the disease at a low cost and is environmentally friendly. The aim of the study was to obtain the best consortium of endophytic bacteria to control anthracnose caused by C. gloeosporioides and improve the growth and yield of chili plants. This research was arranged in an experimental method consisting of two stages, namely (i) compatibility test between endophytic bacterial consisting of 28 species, and (ii) test of the endophytic bacterial consortium ability to control anthracnose in chili using a Completely Randomized Design (CRD) with 14 treatments and provided with 3 replications. All treatments of endophytic bacterial consortium showed the potential to suppress anthracnose disease caused by C. gloeosporioides and improve the growth and yield of chili plants. The best bacterial consortium treatment in suppressing the development of anthracnose disease by C. gloeosporioides and increasing the growth and yield of chili plants was the consortium B. cereus SNE 2.2 + B. cereus TLE 1.1 with dis-ease severity of 0.00%, plant height of 58.33 cm and fruit weight of 208.97 g.

Abstract. Nelly N, Hamid H, Lina EC, Yunisman, Rusli R, Yanti Y, Kairunisa M. 2024. Effectiveness of Bacillus spp. from West Sumatra, Indonesia in controlling Spodoptera frugiperda (Lepidoptera: Noctuidae). Biodiversitas 25: 1472-1478. Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) is an invasive pest widely recognized for attacking corn plants. This pest was first discovered in early 2019 in West Sumatra, Indonesia, posing a significant threat to agricultural productivity. To control S. frugiperda, local biological agents, namely Bacillus spp., originating from West Sumatra, have been explored as a potential control method. Therefore, this study aimed to obtain Bacillus spp isolates from rhizosphere origin and assess their effectiveness in controlling S. frugiperda in the laboratory. A completely randomized design was used, consisting of five treatments with three replications. The treatments included Bacillus cereus strain MRPLUMBE1.3, Bacillus myocytes strain MRRZLL 2.2, and Bacillus sp. MRTE strain 1.3.3. For comparison, there was a synthetic insecticide (active ingredient chlorantraniliprole) and a control (distilled water). The application of isolate suspension was carried out through larvae feed. The parameters observed included larvae mortality, percentage of formed pupae and adults (imago), number of eggs laid by females, and survival time of adults. The data obtained were analyzed using Analysis of Variance (ANOVA) and tested with LSD at the 5% level. The results showed that Bacillus spp. isolates originating from the rhizosphere effectively controlled S. frugiperda larvae. The best isolate that can be used to control S. frugiperda is Bacillus spp. from Solok. Specifically, Bacillus sp. strain MRTPE 1.3.3 showed larvae mortality ranged between 28.33 and 41.67%, and the suspension affected the percentage of formed pupae (51.66%) and the survival time of adults (4.5-5.8 days).

Abstract

Bacterial wilt caused Ralstonia syzygii subsp. indonesiensis is one of the most destructive disease of tomato and results in severe yield losses. Plant growth-promoting rhizobacteria (PGPR) are known to enhance plant growth and health. In previous research, seven selected PGPR strains were identified for their ability to suppress R. syzygii subsp. indonesiensis and promote tomato growth. The present study aimed to evaluate the enzymatic defense responses of tomato plants inoculated with two selected rhizobacterial strains. The strains were assessed for their ability to induce the production of defense-related enzymes, including peroxidase (PO), phenylalanine ammonia-lyase (PAL), polyphenol oxidase (PPO), and lipoxygenase (LO). R. syzigii subsp. indonesiensis was inoculated onto tomato plants seven days after rhizobacterial treatment at the seedling stage. Enzyme activities were recorded from 0 to 30 days after pathogen inoculation at two-day intervals. The results showed a reduction in disease incidence and severity in tomato plants treated with the two rhizobacterial strains compared with the control. E. oryzendophyticus RZ.2.2.AG2 demonstrated greater effectiveness in reducing disease incidence (26%) and severity (2.5) than B. thuringiensis RZ.1.1.AG4. Enzyme activity assays further confirmed that both strains induced plant resistance by increasing PAL, PO, PPO, and LO activities, with significantly higher enzyme activity observed in roots than in leaves. Tomato plants treated with E. oryzendophyticus RZ.2.2.AG2 exhibited the highest enzyme activities in both roots and leaves, indicating that disease suppression was associated with induced systemic resistance (ISR) mediated through activation of defense-related enzymes.
