Abstract

Magnaphorte oryzae is a pathogenic fungus that causes blast disease in rice plants. This disease can cause a decrease in rice production. Therefore, it is necessary to control the disease, one of which is by administering microbes that are antagonistic to Magnaphorte oryzae. This research aims to determine the percentage of inhibitory power of Bacillus subtilis ATTC 6633 and Trichoderma harzianum on the growth of Magnaphorte oryzae with varying soaking times of 24, 48 and 72 hours on the Anak Daro rice variety. This research carried out viability tests for Bacillus subtilis ATTC 6633 and Trichoderma harzianum, as well as antagonist tests using the dual culture method. The results showed that the growth inhibition of Magnaphorte oryzae by Bacillus subtilis ATTC 6633 for a soaking period of 24 hours was 28.48% in the weak category, 48 hours was 32.27% and 72 hours was 31.01% in the medium category. Inhibition of Magnaphorte oryzae by Trichoderma harzianum for a soaking period of 24 hours was 50.63%, 48 hours was 57.59%, and 72 hours was 56.32% in the high category.

Abstract

The majority of Indonesian people consume rice as a staple food. According to data from the Central Statistics Agency (2022), rice production in West Sumatra reached 1,482,996.01 tons in 2019 and continued to decline until 2021, total rice production in West Sumatra was only 1,317,209.38 tons. This is inversely proportional to the population of West Sumatra which increases every year, so efforts need to be made to increase rice production. One of them is the biopriming technique to increase seed vigor. Priming is hydration carried out slowly which aims to ensure that the seed's water potential reaches balance and activates metabolism in the seed before the seed germinates. One of them is biopriming, which is a seed priming technique using biological agents in the form of beneficial microorganisms. Several factors influence the success of the priming technique, one of which is the soaking time. The right soaking time provides a deeper opportunity to absorb water to stimulate the seeds to germinate. This research aims to determine the effect of soaking time on biopriming of the local West Sumatran rice variety "Anak Daro" using Bacillus subtilis and Trichoderma harzianum on the germination of the Anak Daro rice variety. Completely Randomized Design (CRD) factorial pattern with 2 factors with 3 replications. Factor A is a biopriming agent, namely A1 (no microbes), A2 (Bacillus subtilis), and A3 (Trichoderma harzianum). Factor B is the length of soaking, namely B1 (24 hours), B2 (48 hours), and B3 (72 hours). The results showed that Bacillus subtilis and Trichoderma harzianum had a significant effect on maximum growth potential and germination, while soaking time had a significant effect on maximum growth potential and vigor index.

Abstract

Anthracnose disease caused by the fungus Colletotrichum sp. is one of the main problems in chili cultivation (Capsicum annuum L.) and can cause significant yield losses. The intensive use of chemical pesticides in controlling this disease has a negative impact on the environment and health. This study aimed to evaluate the antagonistic potential of phyllosphere fungi isolated from five medicinal plants, namely Phaleria macrocarpa, Curcuma domestica, Kleinhovia hospita, Hibiscus rosa-sinensis, and Morus macroura, against the pathogen Colletotrichum sp. Isolation was performed from leaf surfaces, and a total of 7 phyllosphere fungal isolates were tested using a double culture method with three replicates. The results showed that all isolates were able to inhibit the growth of Colletotrichum sp. through mechanisms of competition for space and nutrients as well as antibiosis, with inhibition levels ranging from high to very high. Among the tested isolates, Trichoderma sp. exhibited the highest inhibitory activity with an inhibition percentage of 92.78%, categorized as very high. Macroscopic and microscopic characterization supported the identification of several isolates belonging to the genera Trichoderma. This study concluded that phyllosphere ungi from medicinal plants have the potential as environmentally friendly biological control agents in combating anthracnose disease in chili plants.

Abstract

Anthracnose caused by Colletotrichum sp. is a major postharvest disease of avocado (Persea americana Mill.) that leads to significant economic losses during storage. This study aimed to evaluate the antifungal efficacy of essential oil-based botanical pesticides derived from lemongrass (Cymbopogon nardus L.), cinnamon (Cinnamomum burmannii L.), and wild betel (Piper aduncum L.) against Colletotrichum sp. in vitro. The experiment was arranged in a Completely Randomized Design (CRD) with nine treatments and three replications, using essential oil concentrations up to 1000 ppm in both single and combined formulations. Antifungal activity was assessed based on colony diameter and fungal biomass, and data were analyzed using Analysis of Variance (ANOVA) followed by Duncan’s New Multiple Range Test (DNMRT). All treatments significantly inhibited fungal growth compared to the control. The smallest colony diameter was recorded in the lemongrass treatment (12.80 mm), with the highest inhibition rate of 85.77%. The lowest fungal biomass was observed in the cinnamon treatment (20 mg). These results demonstrate very strong antifungal activity of the tested essential oils.This study highlights the novelty of utilizing locally sourced essential oils as botanical pesticide formulations targeting Colletotrichum sp., suggesting their potential as environmentally friendly alternatives for sustainable postharvest disease management.

Abstract

This study details the development of a high-performance microbial fuel cell (MFC) utilizing a nanofiber-coated carbon anode, fabricated through the electrospinning of polyvinyl alcohol (PVA) integrated with carbon quantum dots (CQDs). A dual-chamber H-type MFC, with a working volume of 50 mL for both anode and cathode compartments, was operated in batch mode using sterilized sugarcane juice, adjusted to a pH of 7.0, as the organic substrate. Two electrogenic bacteria, Bacillus subtilis and Escherichia coli, were separately immobilized within the PVA/CQD nanofiber matrix to assess their electrochemical performance. Structural and chemical characterizations using SEM, FTIR, and UV–Vis spectroscopy confirmed the successful incorporation of CQDs and effective bacterial colonization within the nanofiber network. Electrochemical studies, such as CV and EIS, indicated low charge transfer resistance and improved electron kinetics especially when B. subtilis was present and an Rct of about 400 ohms. MFCs based on B. subtilis reached a maximum power density of 1754 mW/m² on day four of operation at a fixed external resistance of 100 0 and the electrode surface area of 9.45 cm², about 3.5 times greater than the power density obtained with E. coli (491 mW/m²). This has been due to the high performance of B. subtilis which can form a robust conductive biofilm, releases endogenous redox mediators, and has the ability to metabolize sugar rich substrates efficiently. These findings underscore the potential of PVA/CQD nanofiber-coated carbon anodes as an effective strategy for enhancing MFC performance and provide a promising foundation for future optimization and scale-up toward sustainable energy generation from organic waste at the laboratory level.

Abstract

Fungal diseases remain a major constraint in chili cultivation, particularly anthracnose and Fusarium wilt. This study aimed to evaluate the in vitro biocontrol potential of Trichoderma atroviride and Trichoderma harzianum against Colletotrichum sp. and Fusarium oxysporum f. sp. capsici. The study was conducted experimentally using the dual culture method on Potato Dextrose Agar (PDA) medium with three replications for each treatment. Results showed that both Trichoderma isolates exhibited strong inhibitory activity against the tested pathogens. Trichoderma atroviride showed inhibition percentages of 92% against Colletotrichum sp. and 90% against Fusarium sp., while Trichoderma harzianum inhibited pathogen growth by 73.6% and 85%, respectively. The primary antagonistic mechanism observed was competition for space and nutrients, indicated by the rapid growth of Trichoderma colonies covering the Petri dishes. This study indicates that T. atroviride and T. harzianum have promising in vitro biocontrol potential against Colletotrichum sp. and Fusarium oxysporum f. sp. capsici.

Abstract

Anthracnose is one of the major postharvest diseases affecting avocado (Persea americana Mill.) and is commonly associated with fungi from the genus Colletotrichum. However, other fungal genera may also be associated with anthracnose-like symptoms in avocado fruits. This study aimed to identify fungal isolates associated with anthracnose symptoms on avocado fruits collected from West Sumatra using morphological and molecular approaches. Symptomatic fruits were incubated to induce lesion development, followed by fungal isolation and purification on Potato Dextrose Agar (PDA). Morphological characterization included macroscopic and microscopic observations. Molecular identification was performed using LSU rDNA amplification, sequencing, BLAST analysis, and phylogenetic reconstruction. A single fungal isolate, DTTDL318, was successfully obtained from avocado fruit showing anthracnose symptoms. Morphologically, the isolate exhibited characteristics consistent with the genus Fusarium, including white cottony colonies with orange reverse pigmentation, septate hyphae, fusiform conidia with pointed ends, and thick-walled chlamydospores. LSU sequence analysis indicated that the isolate belongs to the Fusarium solani species complex (FSSC) Phylogenetic analysis demonstrated that isolate DTTDL318 clustered in the same clade with Fusarium cf. solani and Fusarium waltergamsii with a bootstrap value of 88%, indicating a close phylogenetic relationship with members of the Fusarium solani species complex (FSSC). These findings indicate the presence of a Fusarium isolate associated with anthracnose-like lesions on avocado fruits.

Abstract

Seed-borne diseases caused by Colletotrichum and Fusarium can reduce the viability and vigor of chili seeds. An environmentally friendly alternative for disease management is the use of Trichoderma atroviride as a biopriming agent. This study aimed to evaluate the effectiveness of T. atroviride biopriming on the germination of Kopay chili seeds infected with Colletotrichum scovillei and Fusarium oxysporum. The experiment was arranged in a Completely Randomized Design (CRD) consisting of eight treatments with four replications. Observed parameters included germination percentage, root length, shoot length, fresh weight, dry weight, vigor index, and root emergence time. Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s New Multiple Range Test (DNMRT) at the 5% significance level. The results showed that T. atroviride treatment produced the highest germination percentage (100%), which was not significantly different from the positive control (95%) and negative control (90%). The T. atroviride treatment also resulted in the greatest root length (2.54 cm), shoot length (1.74 cm), highest vigor index (100%), and the fastest root emergence (2 days). In contrast, the C. scovillei treatment exhibited the lowest germination percentage (30%) and vigor index (45%). These findings suggest that biopriming with T. atroviride has the potential to enhance seed vigor and support early seedling growth of chili under seed-borne pathogen stress.
