Abstract

Control of bacterial leaf blight in rice plants is often done by applying chemical pesticides whose future effects will be very bad for the soil and plants that will be planted next. An alternative that can be applied is using the biopesticide Fobio. The aim of this research was to measure the effectiveness of the application of fobio in reducing the intensity of bacterial leaf blight attacks. This research was carried out in June-September 2023 in Diwek District, Jombang Regency. The study used a Randomized Block Design with two factors, namely the Fobio dose consisting of 3 levels, namely P0 (without giving Fobio / 0ml/liter), P5 (dose 5 ml/liter), and P10 (dose 10 ml/liter), the second factor was long The soaking time for seeds using Fobio consists of 3 levels, namely W10 (10 minutes soaking time), W20 (20 minutes soaking time), and W30 (30 minutes soaking time) so there are 9 treatment combinations. Observation parameters include plant height, number of leaves, number of tillers, and intensity of disease attacks. The results of the combination treatment were not significantly different for the number of leaves and number of tillers, for single and combination treatments the plant height and intensity of disease attacks were significantly different. Application of Fobio can increase plant height, number of leaves, and number of tillers on rice plants, and Fobio can suppress bacterial leaf blight attacks that attack rice plants.

Abstract

Endophytic bacteria are a group of bacteria that live in plant tissues, potentially as biological agents of plant diseases, especially wilt disease caused by Ralstonia solanacearum and as an inducer of eggplant (Solanum melongena) plant growth. One of these bacteria is Bacillus cereus BTH-22 which was isolated from healthy eggplant stems in Kediri. The purpose and formulation of the problem are to obtain an encapsulation formulation of B. cereus BTH-22 which has the potential as a biological agent against wilt disease caused by R. solanacearum and as an inducer of eggplant (S. melongena) plant growth. The novelty of the research is the encapsulation formulation of B. cereus which is applied to eggplant plants with wilt, because the application generally uses root soaking, watering to the soil surface, mixing with fertilizer, liquid and powder formulations but all are easily washed away by rain. The research method is as follows: (1) Making encapsulation formulation: 75% Na-alginate with 10% aloe vera extract (Na-1) and 75% Na-alginate, 0.875% zeolite and 0.875% sago flour (Na-2), (2) Sterile soil, inoculate R. solanacearum and prepare 1 month old plants, (3) Application of encapsulation formulation was carried out 3 days after inoculation of R. solanacearum (107CFU/mL) using a Completely Randomized Design with 3 replications. Observations were made on days 7, 14, 21, 28, 35, 42, 49 including : disease intensity, plant height, number of leaves, number of flowers. The results of the study showed: viability in the Na-1 and Na-2 treatments was higher than control at the 48th to 96th hours, disease intensity in the Na-1 and Na-2 treatments was lower than control at the 7th to 49th day, plant height in the Na-1 and Na-2 treatments was higher than control at the 14th to 49th day.

Abstract

Wilt disease caused by Fusarium oxysporum is one of the diseases affecting chili plants. The utilization of Bacillus spp. can be a solution for plant disease control because it can colonize plants and produce useful microbe compounds to inhibit the development of plant pathogen. This study aimed to determine the ability of Bacillus spp. to suppress the growth of Fusarium sp. isolates from chili plants in vitro. Bacillus sp. isolates Ba-6, Ba-9, Ba-12, Ba-15, Ba-17, and a control (aquadest) were used as treatments, each replicated four times. The observation parameters were the inhibition zone test and microscopic observations of the morphology of Fusarium sp. after the inhibition zone test. The highest inhibition was shown in the treatment of Bacillus sp. isolate Ba-15, which was 20.02%. The observation of Fusarium sp. hyphae after the inhibition zone test showed abnormal growth, which was different for each isolate. Some hyphae were bent, coiled, shrunken, swollen, curled, or lysed.

Abstract

Background: Seed is a planting material that must have high viability and quality, including being free from pathogens. One of the obstacles in the supply of quality maize seeds is seed-borne fungal pathogen which can affect the quality of maize seeds and cause plant disease. Endophytic bacteria Bacillus sp. has been widely studied to be able to produce secondary metabolites as antifungals. This study aimed to determine the exact concentration of secondary metabolites of endophytic bacteria Bacillus sp. to decrease the infections of seed-borne pathogens fungal on maize seeds using the blotter test method. Methods: This study used a completely randomized design with four concentration levels (10%, 15%, 20%, 25%) and two strain codes of endophytic bacteria Bacillus sp. (Bth-31a and Bth-22). Results: The result of identifying seed-borne fungal pathogen on maize seed included Fusarium sp., Aspergillus flavus, Aspergillus niger, and Rhizopus sp. The Bth-22 treatment with a concentration of 25% could decrease the infection of seed-borne fungal pathogen and had the highest percentage until 50% compared to the control. While the lowest percentage to decrease the infections of seed-borne fungal pathogen occurred in the Bth-31a treatment with a concentration of 10%, which was 32.1% compared to the control. Conclusions: All seed treatments that used secondary metabolites of Bacillus sp. able to decrease the infections of seed-borne fungal pathogen on maize seed compared to the control. In addition, the treatment of secondary metabolites Bacillus sp. is able to increase the germination of maize seeds.

Abstract

Rice (Oryza sativa L.) is one of the important food commodities consumed by the Indonesian people. One of the reasons for the decline in rice production is infection by the pathogen Xanthomonas oryzae pv. oryzae (Xoo) which causes bacterial leaf blight (BLB) and it’s seed-borne pathogen. The purpose of the experiment is to to evaluate the effectiveness of seed soaking using Paenibacillus sp. to control BLB in rice plants. Efforts to control BLB and improve rice plant growth were carried out by seed treatment using biocontrol agent has potential as biological control for BLB in rice plants by producing antibiotic. This experiment used a Completely Randomized Design with 4 treatments (control, Paenibacillus sp., Bacillus sp. BTH22, Paenibacillus polymyxa) and 5 replications. Data analysis was performed using analysis of variance (ANOVA) at a 5% significance level using IBM SPSS Statistics version 22 software. If the analysis results showed significant differences between treatments, an Honestly Significant Difference (HSD) test was performed at the 5% level. The research results showed that seed soaking using Paenibacillus sp. was able to reduce the incubation period of HDB disease by up to 11 days, with the lowest disease attack intensity being 10.21%, the highest seed germination rate being 91.25%, and an efficacy level of 53.32%.

Abstract

Rice is a major food commodity in Indonesia that is currently experiencing a decline in production due to several factors, one of which is bacterial leaf blight (BLB) caused by the bacterium Xanthomonas sp. The use of chemicals in controlling this disease has many limitations, so alternatives are needed, such as antagonistic microbes. This study aims to evaluate the effectiveness of Bacillus sp. BTH22 and Trichoderma sp. individually and in consortium in suppressing BLB disease in rice plants in vitro and in vivo. The study was conducted at the Plant Health Laboratory of  Universitas Pembangunan Nasional “Veteran” Jawa Timur and Green House of Kebun Bibit Wonorejo from March to June 2025. The methods used included in vitro diffusion well test and in vivo disease intensity observation with a completely randomized design consisting of 5 treatments, namely control and spraying of antagonistic microbes Bacillus sp. BTH22 and Trichoderma sp. alone or in consortium with 4 replicates. Data analysis used analysis of variance (ANOVA) and post-hoc HSD tests at a 5% significance level. The results show that the treatment with the Bacillus sp. BTH22 and Trichoderma sp. consortium was the most effective, with an inhibition zone of 13 mm, which is classified as strong, and the lowest disease intensity of 30.02% at 55 HST with a suppression rate of 69.98%. These results indicate that the consortium of the two antagonistic microorganisms has high potential as an effective and sustainable biological control agent for BLB based on the observed parameters of inhibition zone and disease attack intensity.
