Abstract

The Potential of Plant Growth-Promoting Bacteria to Suppress Infection of Cucumber mosaic virus on Cucumber Plants Mosaic disease caused by Cucumber mosaic virus (CMV) is one of the main diseases of cucumber plants, and is economically important. Plant growth-promoting bacteria (PGPB) are plant root organisms currently being developed as biological agents. This research aims to obtain the best PGPB that can suppress the development of CMV in cucumber plants. This research used a randomized block design with nine treatments and five replications. The treatments consisted of several isolates of PGPB (Serratia marsescens AR1, Alcaligenes faecalis AJ14, Stenotrophomonas pavanii KJKB 5.4, Pseudomonas fluorescens LPK1–9, Bacillus cereus AJ 34, and S. maltophilia LMTSA 5.4), orthohydroxybenzoic acid (salicylic acid), positive control, and negative control. Application of PGPB was conducted through seed treatment of cucumber seeds for 15 minutes before planting. The mosaic virus was mechanically inoculated on cucumber cotyledons seven days after planting. The variables observed were the development of mosaic disease and the growth of cucumber plants. Virus detection using specific primer pair CMV-IF/CMV-IR showed that the virus that infected cucumber plants had 98.3% similarity to the CMV isolate originating from India with accession number KJ874248.1. Pseudomonas fluorescens LPK1-9 is the best bacteria for slowing the incubation period, reducing the percentage of infected leaves, and reducing the severity of mosaic disease on cucumber plants. None of tested PGPB isolates that has the potential to increase the growth of CMV-infected cucumber plants. Therefore, further studies are needed on the effectiveness of the PGPB, such as improving how PGPB is applied.

Abstract

Yellow disease in eggplant caused by a virus transmitted by Bemisia tabaci has become a serious threat to the sustainability of horticultural production in Padang City. The high dependence of farmers on chemical pesticides has the potential to induce pest resistance, environmental pollution, and health risks. This activity was conducted to enhance farmers’ capacity to recognize and control insect vectors of yellow disease through the application of eco-enzymes derived from fermented local plant organic waste as an environmentally friendly alternative control strategy. The methods applied included training, field demonstrations, mentoring, and the application of eco-enzymes in treatment plots, while chemical pesticides were applied in control plots. The results indicated that farmers’ knowledge increased by 80%. However, the incidence of yellow disease in the eco-enzyme treatment was 10% higher than that in the control, with disease severity being 3.11% higher. A production difference of 1.53 kg was observed, although plants treated with eco-enzymes exhibited better overall plant health, whereas 5% plant mortality was found in the control plots. It was concluded that eco-enzymes have not yet been effective as a single technology for controlling yellow disease in eggplant under field conditions. Therefore, the implementation of integrated pest management is required through the integration of natural enemies, the conservation of refugia plants, and the control of other pests such as shoot borer.

Abstract

Bacterial grain rot is one of the diseases caused by the bacterium Burkholderia glumae in the rice plant. This disease can cause a 40% loss in rice crop yield. One technique for controlling this disease is to use biological control agents, specifically endophytic bacteria. The study aimed to obtain endophytic bacterial isolates that can potentially suppress grain rot disease (B. glumae) in rice plants. The study was conducted experimentally using a completely randomized design (CRD) with 13 treatments and three replicates, each consisting of 2 experimental units. The treatments consisted of endophytic bacterial isolates BMI31, BMI33, ADI34, ADI35, ADI37, KKI35, KKI36, BI31, BI33, BI34, BI41, BPI41, a positive and a negative control. Endophytic bacteria were introduced into rice seeds and roots 21 days after sowing, while B. glumae was inoculated into rice plants at 45 days after sowing. The results of the study indicate that the endophytic bacteria with potential to control the development of bacterial grain rot disease in rice plants are isolates BMI33 and ADI35, with disease severity levels of 30.74%– 32.64% and effectiveness of 49.55–52.48%, AUDPC values of 293.99-351.95, and a percentage of disease development suppression effectiveness of 60.73%- 70.61%. The results show that endophytic bacterial isolates have the potential to become biological control agents.

Abstract

Anthracnose is a disease caused by Colletotrichum sp., which can reduce the quality and yield of red chili by 45-60%. This study aimed to determine the ability of different Beauveria bassiana isolates to control anthracnose in chili. The research employed a Randomized Block Design (RBD) consisting of 6 treatments and 5 replications. The treatments included a control and 5 different B. bassiana isolates (PD114, TD312, WS, BbKo, KT2B21). The observed variables included incubation period, disease incidence and severity, plant height, number of leaves, flowering time, and chili fruit weight. The results showed that the application of different B. bassiana isolates have effectively inhibited the development of Colletotrichum truncatum, which caused anthracnose in chili. B. bassiana has demonstrated the ability to prolong the incubation period of C. truncatum (5.40 days) and reduce the percentage of disease incidence (16%). Furthermore, the application of B. bassiana increased the height of chili plants (40.40 cm) and the number of leaves (32 leaves), accelerated the flowering time (42.80 days), and boosted chili production (178.25 g). The WS and TD312 isolates revealed the most significant results. Although the severity of the disease was not impacted, the 2 isolates provided notable agronomic benefits to the chili plants.

Abstract

Nagari Sungai Abang is one of the areas in Lubuk Alung District, one of the rice production centers in Padang Pariaman Regency. One farming group that intensively cultivates rice is the Farming Business group. The problem with the farmer groups is their ignorance of the benefits of straw as a source of organic matter in the soil. The composting process is long, so farmers always burn rice straw after harvest in preparation for planting the following season. If the burning of straw is carried out continuously, it is feared that nutrients will be deficient in the soil. This activity aims to empower Farming Business groups in Nagari Sungai Abang, Lubuk Alung District, to utilize Plant Growth Promoting Rhizobacteria (PGPR) as a bio activator in making straw compost as organic fertilizer and an alternative to addressing the problem of straw waste in Nagari Sungai Abang, Lubuk Alung. This activity has been carried out in the Farming Group of Farmers in Sungai Abang Dalam Nagari Sungai Abang, Lubuk Alung District, Padang Pariaman Regency. The method used is outreach, counseling, and training to demonstrate making PGPR suspension and compost from straw. From the activities that have been carried out, ready-to-use PGPR is obtained as a bio activator reproduced in coconut water media and used as a bio activator to speed up the composting process. The conclusion of this activity is increasing farmers' understanding of the benefits of straw as a raw material for compost and the use of PGPR as a bioactivator in making straw compost.

Abstract

Background: Red chili pepper (Capsicum annuum L.) is a leading horticultural commodity in Indonesia, but its productivity is often limited by insect-transmitted viral diseases. Objective: This study aimed to determine the incidence of viral disease, the population dynamics, and the species of insect vectors on red chili pepper in Sukarami, Gunung Talang District, Solok Regency. Methods: Direct field observation was conducted on a 0.0273 ha plot (800 plants) in Jorong Sukarami, Nagari Koto Gaek Guguk, from November 2024 to April 2025. One hundred sample plants across five diagonally-arranged subplots were observed. Disease incidence (IP = n/N × 100%) was recorded weekly from 21 to 98 days after planting (DAP), while vector populations were counted visually at four critical phases: vegetative, flowering, fruiting, and post-harvest. Results: The incidence of virus-like symptoms increased progressively from 6% at 3 weeks after planting (WAP) to 73% at 14 WAP, with the sharpest increase (16 percentage points) occurring between the 8th and 9th week during flowering. Bemisia tabaci was the dominant vector, rising from 8 individuals at the vegetative phase to 57 after harvest, while Myzus persicae appeared only after the first harvest (16 individuals). Conclusion: Disease incidence increased concurrently with B. tabaci population, suggesting a temporal association between disease development and vector abundance. Early monitoring and management of B. tabaci during the vegetative phase is therefore recommended to reduce virus transmission risk
