Abstract

Meloidogyne spp. is responsible of root swelling, one of the primary disease in tomato plants. Controlling this nematode is challenging due to its wide host range. The use of synthetic nematicides harms the environment; therefore, alternative controls, such as biological methods, are necessary. Among the biological agents, one group includes endophytic bacteria that reside in plant tissues and do not cause harm to plants. These bacteria enhance plant resistance to pests and pathogens while promoting plant growth. The study aimed to acquire endophytes, Bacillus spp. strains capable of controlling Meloidogyne sp. while stimulating the growth of tomato plants. The research employed a completely randomized design (CRD) comprising seven treatments and five replications. The treatments consisted of B. cereus strain SNE 2.2, TLE 2.3 and TLE 1.1, B. pseudomycoides strain EPL 1.1.3, B. toyonensis strain EPL 1.1.4, positive control (without the introduction of Bacillus spp. and inoculation with Meloidogyne sp.) and negative control (without Bacillus spp. and without Meloidogyne sp.). Bacillus spp. endophyites were introduced in two stages: into the seeds and into the roots of tomato seedlings for 15 min. The observed variables were the development of Meloidogyne sp., endophytic colonization of Bacillus spp., and plant growth. The results demonstrated that all Bacillus spp. were effective in controlling Meloidogyne sp. and enhancing the growth of tomato plants. The best isolate in controlling Meloidogyne sp. and increasing the growth of tomato plants was B. cereus strain SNE2.2.

Abstract

One of the constraints in rice production is grain rot disease caused by Burkholderia glumae, which can be carried by seeds grain. An observation to determine the presence of B. glumae in different grain yield classes of seeds was conducted by taking samples derived from several seed producers in South Sulawesi. This research was carried out by first taking seed samples at the South Sulawesi Agricultural Technology Study Center (BPTP), Tungro Research Workshop, South Sulawesi Main Seed Center (Balai Benih Induk), PT. Sang Hyang Seri, PT. Pertani and PT. Harmoni were then tested at the Agricultural Quarantine Laboratory of Makassar. Based on the observations, it was concluded that all samples in the sowing seed class tested positive for B. glumae, supported by an average percentage of disease incidence of 25.13%, namely foundation seeds from the Balai Benih Induk, as well as foundation seeds and stock seeds from AIAT.

Abstract

The association of viral satellite DNA with Begomoviruses influences symptom expression in infected plants. Normalized Difference Vegetation Index (NDVI) is an image processing method used to assess plant health based on the plant’s ability to absorb sunlight for photosynthesis. Therefore, this study aims to assess symptom severity based on symptom variation and NDVI, as well as to detect and identify the presence of beta-satellite DNA associated with chili plants. The study was conducted in North Kolaka Regency, Southeast Sulawesi Province, Indonesia. It involved observations and image recording of symptom variations in the sampled cayenne and big red chili plants, followed by the detection of beta-satellite DNA in the samples using the polymerase chain reaction (PCR). The results confirmed the presence of non-coding satellite DNA associated with the Pepper yellow leaf curl Indonesia virus (PepYLCIV) in all severe, mild, or asymptomatic plant samples. In the phylogenetic tree, the non-coding satellite DNA isolates from Southeast Sulawesi are included in the betasatellite group and exhibit different genetic characteristics from other isolates available in the GenBank database. The cayenne chili with severe symptoms had lower NDVI values than the mild and asymptomatic categories, indicating that this type of chili with severe symptoms had a lower ability to absorb light. Further studies are needed to characterize the alpha-satellite type in the Southeast Sulawesi region for potential use in cross-protection mechanisms against plant virus infections.

Abstract

The use of several shallot varieties applied with the biological agent Bacillus spp. is one of the most developed methods of controlling twisted disease, as it is safe and efficient. The large number of shallot varieties released to farmers requires the selection of varieties with the best resistance response to twisted disease. This study aimed to determine the different responses between five local shallot varieties treated with a combination of Bacillus velezensis B-27 and B. cereus RC76 against the twisted disease. This study was conducted in a greenhouse and on the field using Tajuk, Bima Brebes, Bauji, Crok Kuning, and Manjung varieties, which were dipped and sprayed with a B. velezensis B-27 and B. cereus RC76. The treatment of B. velezensis B-27 and B. cereus RC76 on five varieties showed a good response to suppressing twisted disease. The twisted disease incubation period in five varieties treated with the combination of B. velezensis B-27 and B. cereus RC76 showed a slower result than the control, the disease incidence and intensity could be reduced by 70 90%. The best resistance response of varieties treated with the combination of B. velezensis B-27 and B. cereus RC76 was shown by Tajuk compared to the other four varieties.

Abstract

Coffee berry borer pest (CBB) is one of the main pests that has a significant impact on coffee production and quality. In Indonesia, the utilization of plant-based pesticides has promising prospects in controlling CBB. The purpose of this study is to provide information on the impact of different types of plant pesticide on CBB mortality through a measurable algorithm analysis. A literature search was performed using Scopus, Web of Science, Google Scholar, Researchgate, and ScienceDirect. A linear mixed model (LMM) was applied to evaluate the effect of botanical pesticide application on the mortality rate of CBB. A total of 14 plant families were included in meta-regression analysis for estimating the effect size of each family. The average effect of pesticide exposure to CBB analyzed using LMM was 0.039 which mean that botanical pesticidal exposure has significant effect on the mortality rate of CBB (P<0.05). The results of this study suggested that the use of botanical insecticide especially derived from plants belonging to Family Anacardiaceae was significantly effective in controlling CBB.

Abstract

Spodoptera frugiperda J.E. Smith (Spodoptera: Noctuidae) is an invasive pests of maize that has been reported around the world. Control efforts using biological agents continue to be developed, including the use of entomopathogen bacteria such as Bacillus thuringiensis. To boost the efficacy and efficiency of biological control, formulations are required. The objective of this study was to develop biopesticide formulations and evaluate their efficacy. The research was carried out by formulating B. thuringiensis strain BtJ2 (1010 cfu mL -1) in liquid and paste formulations. The effectiveness of the formulations was evaluated using the feed dipping method. The results showed that paste formulations at a concentration of 10% caused 100% mortality, whereas the liquid formulation resulted in 85% mortality. The LC90 for the paste formulation was 6.66%, while the LC90 for the liquid formulation was 12.90%. Both the liquid and paste formulations had similar effects on mortality and viability. Based on the LC90 and LT90, the paste formulation was more efficient and faster in killing S. frugiperda than the liquid formulation. The results of this study provide recommendations that B. thuringiensis as a bioinsecticide is better formulated in a paste than in a liquid form.

Abstract

Plant growth-promoting rhizobacteria (PGPR) is a promising technology for controlling viral diseases, including pepper yellow leaf curl disease (PYLCD) of chili pepper caused by Begomovirus infection. The objectives of this research were to investigate the effectiveness of PGPR containing Pseudomonas fluorescens PF1 and Bacillus polymyxa BG25, as well as their combination with other protective agents, to control PYLCD under field conditions in an endemic region. The treatments consisted of a single application of PGPR (a mixture of P. fluorescens PF1 and B. polymyxa BG25), guano tea, endophytic fungus H5, and neem oil; combination of PGPR with guano tea, endophytic fungus H5, and neem oil; conventional pesticide that relies on synthetic chemical insecticide sprayed weekly; and untreated plots. The experiment was arranged in a randomized block design with four replications. Treatment with PGPR alone was able to delay disease onset by 2.25 weeks, but it caused only a slight reduction in disease incidence. The combination of PGPR + guano tea and PGPR + endophyte H5 provided the best results in controlling PYLCD. The combination of PGPR + guano tea and PGPR + endophyte H5 delayed disease onset by 2.75 weeks and 3.25 weeks, respectively, and reduced disease incidence with effectiveness rates of 52.72% and 52.08%, respectively. These two treatment combinations gave the best performance for plant growth and yield.

Abstract

This study explored the effectiveness of ethanol and methanol as attractants for controlling the coffee berry borer (CBB), Hypothenemus hampei Ferr 1867, a significant pest in global coffee plantations. The research aimed to assess the efficiency of these substances as attractant traps for CBB in Kaliselogiri, Banyuwangi, Indonesia. Using a single-factor randomized block design, the experiment involved nine treatments, each replicated three times, with modified PTE traps of 2 L volume set up at 1.5 m height. Traps were checked weekly to monitor CBB attack intensity before and after applying attractants. Statistical analyses including the Mann-Whitney Non-parametric test and Duncan’s test were used to examine variations across blocks and weeks. Abundance boxplot graphs offered descriptive insights. Over six weeks, 14,044 CBB’s were captured. The peak was in the third week, with a decline in the fourth, followed by a resurgence until the end of the study. The Mann-Whitney U test showed a significant p-value (p = 0.000; confidence level = 5%), confirming the effectiveness of the attractants on CBB. Of the treatments, K6 (Ethanol: Methanol = 2:1) was most effective. Ethanol and methanol proved to be efficient lures in CBB management traps, with ethanol particularly effective in larger compositions, suggesting its wider application. These results support the use of attractant-based strategies for CBB control and highlight the importance of ethanol and methanol. Further research is needed to optimize attractant compositions and assess long-term impacts on CBB populations and agroecosystems. The ecological consequences, including potential effects on non-target species and overall sustainability, warrant further investigation. In summary, this study advances CBB management through attractant-based traps, emphasizing the importance of ethanol.

Abstract

In the 21st century, population growth affects food demand, especially rice. Xanthomonas oryzae pv. oryzae causes bacterial leaf blight (BLB) disease, the worldwide rice production problem. As pathogen pathotypes vary, research into disease control advances rapidly. Thus, these trends must be mapped to inform future studies. This study aims to examine previous research using bibliometric and scientometric methods to inform future research. Scopus publication data was analyzed utilizing VOSviewer and CiteSpace. Research progress, popular research, productive countries, productive researchers, essential keywords, and global collaboration were explored. Analysis of recent research data predicts future trends. The findings indicate that 21st-century BLB research is advancing at an astounding rate and significantly surpasses that of previous periods, with 596 articles (91.69%) published during this era. Agricultural and Biological Sciences is the leading focus due to its substantial emphasis on genetics-related issues. A statistical analysis of the most prolific countries over the past two decades reveals that the United States, China, and India produce the highest number of articles. China and India are the two largest rice producers, respectively. Nevertheless, the most productive authors reveal that Szurek B (a French scientist) ranks first with a staggering twenty articles. Three main research clusters were found that consisted of “antibacterial agents vs. bacterial disease,” “plant resistance and immunity mechanisms,” and “pathogen virulence and pathogenicity genes.” The study about resistance genes against disease became the most cited article. We concluded that there are several future insights, including “further investigation into the alternative antibacterial agent and their formulation,” “spatial distribution, severity, and prevalence of BLB in multiple conditions,” “the microbial community on plant leaves,” and “additional research to comprehend the mechanism of the microbial community in the rice rhizosphere.” In addition, research on the stability of plant resistance genes to anticipate changes in pathogen pathotypes will be an alternative topic.

Abstract

Plutella xylostella Linnaeus (Lepidoptera: Plutellidaae) is an important pest on Brassicaceae plants, especially cabbage. The combination of entomopathogenic fungi and botanical pesticides has been widely developed to increase effectiveness effectiveness against P. xylostella . This research aimed to determine the potential of Metarhizium anisopliae and Aglaia odorata Leaf Extract (Ao-LE) as a combined control strategy for P. xylostella. The parameters observed in this research were colony growth, viability of conidia of M. anisopliae, antifeedant activity, mortality, and lethal time 50 (LT50) of P. xylostella . The findings revealed that Ao-LE addition maintained colony growth comparable to that of the control treatment, while significantly enhancing the conidial viability of M. anisopliae. Notably, 0.80% and 1.00% Ao-LE in the M. anisopliae suspension resulted in maximum antifeeding activity. Moreover, incorporating 0.20-1.00% Ao-LE demonstrably improved P. xylostella mortality compared with M. anisopliae alone. The combination of M. anisopliae 107 conidia/mL and 1.00% Ao-LE exhibited the lowest LT50 value of 2.16 days, highlighting the synergistic effect of the combined treatment. In conclusion, this study provides compelling evidence for the compatibility and synergistic potential of M. anisopliae and Ao-LE, presenting a promising strategy for the sustainable management of P. xylostella infestations.
