Abstract

Peningkatan permintaan cabai di Indonesia diiringi dengan tantangan produksi, salah satunya adalah penyakit antraknosa yang disebabkan oleh Colletotrichum sp. Penyakit ini menurunkan hasil dan kualitas buah, dan umumnya dikendalikan dengan fungisida kimia. Penggunaan fungisida kimia menimbulkan risiko terhadap kesehatan dan lingkungan, sehingga diperlukan alternatif pengendalian hayati. Penelitian ini bertujuan untuk mengetahui efektivitas ekstrak bawang putih sebagai agen hayati terhadap Colletotrichum sp. secara in vitro dan membandingkannya dengan fungisida propineb. Penelitian menggunakan rancangan acak lengkap faktorial (RALF) dengan dua faktor, yaitu jenis perlakuan (ekstrak bawang putih dan fungisida kimia) dan konsentrasi (5%, 10%, dan 15%). Parameter yang diamati meliputi diameter koloni, persentase hambatan, intensitas serangan pada buah, serta karakteristik makro dan mikroskopis jamur. Hasil menunjukkan bahwa ekstrak bawang putih 15% mampu menghambat pertumbuhan jamur sebesar 38.73% dan intensitas serangan sebesar 21.33%, sedangkan fungisida propineb 5% menunjukkan hambatan tertinggi sebesar 78.43% dan intensitas serangan terendah sebesar 2.67%. Hasil ini menunjukkan bahwa ekstrak bawang putih memiliki potensi antijamur. namun efektivitasnya masih lebih rendah dibandingkan propineb.

Abstract

The intensive use of propineb-based fungicides in agriculture can negatively affect the environment due to toxic and persistent residues in soil. An environmentally friendly approach to reduce these impacts is bioremediation using microorganisms such as Streptomyces sp. This study aimed to examine the tolerance and biodegradation potential of Streptomyces sp. toward 70% propineb fungicide under in vitro conditions. The research was conducted at the Plant Health 1 Laboratory, Universitas Pembangunan Nasional “Veteran” East Java, from June to August 2025. The experiments were carried out in two stages: (1) a tolerance assay on Glucose Nutrient Agar containing propineb at 0; 0,50; 1,00; 1,50; and 2,00 g/L, and (2) a degradation assay using a dual-culture method with Colletotrichum sp. as a bioindicator. Observation variables included Total Plate Count (TPC) of Streptomyces sp., colony diameter of Colletotrichum sp., and the relative inhibition level (THR). Results showed that Streptomyces sp. was able to grow at all fungicide concentrations. The highest population was found in P0 (0 g/L) with 1,42×1013 CFU/mL with growth decreasing as propineb concentration increased, reaching the lowest level of 3,22×10¹⁰ CFU/mL in P4 (2.00 g/L). In the degradation assay, Colletotrichum sp. colony diameter decreased from 3,38 cm in P0 (0 g/L)  to 2,24 cm in P4 (2,00 g/L). Meanwhile, THR values increased consistently with fungicide concentration, rising from 3,17% in P0 (0 g/L)  to 35,48% in P4 (2,00 g/L).

Abstract

Spodoptera exigua is a major pest of shallots (Allium ascalonicum L.), capable of causing up to 100% yield loss if uncontrolled. Streptomyces sp. is a soil-dwelling Actinomycetes bacterium that can be used to control S. exigua. This study aimed to determine the potential of Streptomyces spp. isolates from shallot fields as an entomopathogen against S. exigua. The research employed a Factorial Complete Randomized Design (CRD). The first factor consisted of one Streptomyces spp. isolate obtained from the Pare-Kediri region (BMP) and three isolates from Sidera-Palu (BMS1, BMS2, and BMS3). The second factor was the concentration of the Streptomyces sp. suspension consist of 0%; 5%; 10%; and 15% with three replication per treatment (48 units total). Data on larval mortality and damage intensity were analyzed using RStudio via ANOVA and DMRT (α=5%). The BMP (15%) treatment demonstrated the highest efficacy, achieving 76.67% larval mortality while maintaining the lowest damage intensity of 0.20% on shallot plants. These results highlight BMP isolate at 15% concentration as the most promising biocontrol agent and support its further field evaluation as a sustainable alternative to chemical insecticides.

Abstract

Background: Curvularia sp. is a seed-borne pathogenic fungus that can reduce rice plant productivity. At the same time, conventional seed health testing methods still rely on visual observation and require a relatively long incubation time. This study aims to evaluate the potential of infrared image analysis based on a modified imaging system for early detection of Curvularia sp. infection in rice seeds. Methods: Seed health testing was performed using the blotter test method. At the same time, image acquisition was performed with a digital microscope equipped with an infrared light source, and images were analyzed using pseudocoloring and RGB-based color segmentation. Results: The results showed differences in infrared signal intensity patterns in Curvularia sp.-inoculated seeds, which could be identified on the fourth day after inoculation, earlier than visual observation, which showed symptoms on the fifth day. Detection accuracy was calculated using a confusion matrix based on visual observation as the reference method, with a sample size of 50 seeds per observation day, yielding an average detection accuracy of 91% over seven days of observation. Conclusions: The modified infrared image analysis method has the potential to serve as an early detection method for Curvularia sp. infection in rice seeds, although its performance depends on the limitations of the imaging system and the validation method used.

Abstract

Background: Fusarium sp. is one of the main threats to chili cultivation, thereby reducing its economic value. Therefore, the use of biological microorganisms, such as Trichoderma sp., is an environmentally friendly alternative for controlling Fusarium sp. Application techniques for Trichoderma sp. biological agents include seed coating or encapsulation. However, ensuring the quality and effectiveness of encapsulated products during storage and distribution remains a concern. Thus, this study aims to examine the effects of packaging type and storage temperature on the viability and efficacy of Trichoderma sp. biological agents encapsulated in red chili seeds (Capsicum annuum L.) for inhibiting Fusarium sp. Methods: This study applied a completely randomized design (CRD) factorial with two factors, namely packaging material (aluminum foil and plastic) and storage temperature (5°C, 28°C, and 36°C), resulting in 7 treatments with three replications plus a control, resulting in a total of 21 experimental units. Results: Aluminum foil packaging stored at 28°C showed the highest viability of Trichoderma sp. and the most effective antagonistic activity against Fusarium sp. Conclusion: These results provide a sustainable, environmentally friendly solution for biological-agent-based seed storage.

Abstract

Low-quality seeds can negatively affect the success of agricultural practices by reducing yield and increasing susceptibility to pathogen infection. Pathogens may infect seeds starting from the field, during transportation, and throughout storage. The utilization of Bacillus sp. as a biological control agent has been extensively studied due to its ability to produce secondary metabolites with antifungal properties. This study aimed to determine the effective concentration level of secondary metabolites of Bacillus sp. Bth-22 in suppressing Colletotrichum sp. infection on chili pepper (Capsicum frutescens L.) seeds using the blotter test method. The experiment was arranged in a completely randomized design (CRD) with a single factor consisting of concentration levels (10%, 15%, 20%, 25%, and 30%), sterile distilled water, and the chemical fungicide propineb as controls. The results showed that treatment with various concentrations of secondary metabolites of Bacillus sp. Bth-22 significantly affected the infection level, with concentrations of 30% (G) at 36%; 25% (F) and KP (B) at 38.6%; 20% (E) at 40%; 15% (D) at 42.6%; and 10% (C) at 44%, compared with the negative control. In addition, treatments also suppressed infection levels, with 30% (G) at 43.3%; 25% (F) and KP (B) at 39.3%; 20% (E) at 37%; 15% (D) at 33.6%; and 10% (C) at 31%. Furthermore, application of Bacillus sp. Bth-22 secondary metabolites induced abnormalities in fungal hyphae, such as curling, twisting, and bending, indicating antifungal activity of the bioactive compounds produced by Bacillus sp. Bth-22.

Abstract

Stem rot disease caused by Fusarium oxysporum poses a significant challenge to vanilla (Vanilla planifoliaAndrews) cultivation. The use of microbial-based biopesticides, such as FOBIO, provides an environmentallyfriendly alternative to reduce reliance on chemical fungicides. This study aimed to evaluate the effects of FOBIObiopesticide storage age and concentration on disease intensity and vanilla plant growth (Vanilla planifoliaAndrews). The research was conducted from March to June 2025 in Dusun Tukum using a factorial completelyrandomized design with two factors: FOBIO storage age (6 months and 1 year) and concentrations (5, 7.5, and 10mL/L of water), with three replications totaling 105 plants. Data were analyzed using Analysis of Covariance(ANCOVA), followed by the Least Significant Difference (LSD) test at a 5% significance level. The resultsdemonstrated that the FOBIO application significantly reduced disease intensity compared to the control (p <0.05). The most effective treatment was FOBIO stored for 1 year at a concentration of 7.5 mL/L of water (FP23B),resulting in a final disease intensity of 6.365 compared to 38.255 in the control. FOBIO also increased leaf numberand stimulated plant growth during the vegetative phase, including accelerating flower development. The FOBIObiopesticide is an environmentally friendly alternative for controlling stem rot in vanilla and serves as a biologicalcontrol agent with potential to support sustainable agriculture.

Abstract

This study aimed to evaluate the effectiveness of laboratory-collected Bacillus spp. isolates against Rhizoctonia solani, the causal agent of maize sheath blight, under both in vitro and in vivo conditions, as available information on their efficacy remains limited. The in vitro assay was conducted using the dual culture method with five Bacillus spp. isolates, namely Bcz-14, Bcz-16, Bcz-20, Bcz-21, and Bcz-30, to assess their inhibitory activity against R. solani. The results showed that all isolates were able to inhibit pathogen growth, although the percentage of inhibition varied among isolates. Isolate Bcz-14 exhibited the highest mean inhibition, while isolates Bcz-16 and Bcz-21 were selected for the in vivo assay based on a combination of mean inhibitory activity and consistency across replications. The in vivo assay was conducted using the two selected isolates with different application times, namely seven days before planting and at planting. The results indicated that treatment B1T1, consisting of Bcz-16 applied seven days before planting, showed a greater tendency to suppress disease development, as indicated by a longer incubation period and the lowest disease intensity of 17.78%. These findings suggest that isolate Bcz-16 has potential for further development as a biological control candidate for maize sheath blight. However, further evaluation under field conditions is required to confirm its effectiveness.

Abstract

Background: Fusarium wilt, caused by Fusarium sp., is one of the main obstacles to chili pepper (Capsicum frutescens L.) production. Disease control using chemical pesticides and fungicides is considered effective in agricultural fields, but excessive use can result in environmental contamination and health risks, including cancer. This makes the application of biological control an effective strategy in overcoming Fusarium wilt disease in chili plants, especially in increasing plant productivity. This study aims to test the effectiveness of biopriming using Beauveria bassiana secondary metabolites in suppressing Fusarium wilt infection in chili seeds in vivo. Methodology: This study used a Completely Randomized Design (CRD). Secondary metabolites were applied to chili seeds at four concentration levels (15%, 25%, 35%, and 45%) as well as positive and negative controls. The treated seeds were planted in a medium inoculated with pathogens and observed for nine weeks. Disease intensity was recorded every seven days and analyzed using ANOVA followed by Tukey's Honestly Significant Difference (HSD) test at the 5% level. Findings:  The results of the variance test 49–63 days after sowing (DAS) showed significant differences between treatments; a further HSD test was conducted at a 5% level. The application of Beauveria bassiana secondary metabolites as a biopriming agent on chili seeds is considered to be ineffective. Contributions: This study provides the first in vivo evidence on the application of Beauveria bassiana secondary metabolites as a seed biopriming agent to suppress Fusarium wilt in chili plants, thereby advancing preventive biocontrol strategies and contributing to the development of environmentally sustainable plant disease management
