Abstract

Spodoptera frugiperda is an invasive pest that causes severe damage to maize crops in Kulon Progo Regency. One biological control effort against this pest is the use of the egg parasitoid Telenomus remus. This study aimed to analyze the parasitization rate, parasitism rate, sex ratio, and their correlations in T. remus parasitizing S. frugiperda eggs in maize fields in Kulon Progo Regency. Egg samples were collected from maize fields using a W-pattern scouting method and reared under laboratory conditions until adult parasitoids or host larvae emerged. The number of parasitized eggs, successful parasitoid emergence, and the proportion of female and male individuals were recorded. The results showed that T. remus exhibited a relatively high parasitization rate, while the parasitism rate was moderate, with a female-biased sex ratio. Correlation analysis indicated that parasitization rate, parasitism rate, and sex ratio were not significantly correlated. These findings indicate that the developmental success of T. remus is influenced more by the biological condition of host eggs than by the number of eggs parasitized.

Abstract

extensive use of synthetic herbicides has raised environmental concerns and contributed to herbicide-resistant weeds, emphasizing the need for environmentally friendly weed-management alternatives. Sorghum is known for its allelopathic properties, but nformation on potential allelochemicals in sorghum ratoon leaves remains limited. This study aimed to characterize the chemical constituents of sorghum ratoon leaf extracts and assess their potential relevance to allelopathy based on GC-MS profiling and previously reported biological activities. Ratoon leaves were sequentially macerated using n-hexane, ethyl acetate, and ethanol. Compounds were identified by Gas Chromatography–Mass Spectrometry (GC-MS) and evaluated according to chromatographic peak areas, chemical classes, and reported biological activities. The analysis detected alcohols and phenolic-related compounds, fatty acids, fatty acid esters, amides, sterols, steroids, triterpenoids, and organometallic-related compounds. Several of these groups have previously been associated with allelopathic or phytotoxic activity. Polar compounds may warrant further investigation for aqueous bioherbicide formulations, while fatty acids, esters, and amides may also be relevant to plant growth inhibition. However, their biological effects cannot be confirmed by GCMS profiling alone. Further bioactivity, dose-response, and target-weed assays are required to validate their phytotoxic potential and suitability for natural bioherbicide development. These findings therefore provide a chemical basis for subsequent experimental validation.

Abstract

Anthracnose, caused by Colletotrichum gloeosporioides, is a major disease affecting horticultural crops because it can significantly reduce both the quality and quantity of harvested products. Cutinase plays a crucial role in the early stages of infection by enabling the pathogen to penetrate the plant cuticle, which serves as the first line of host defense. This study aimed to evaluate the potential of bioactive compounds from betel as inhibitors of C. gloeosporioides cutinase using molecular docking. A total of nine compounds were analyzed through PASS biological activity prediction, ADMET-based physicochemical and toxicity assessment, and molecular docking simulations. The PASS analysis revealed that all compounds had higher probability of activity (Pa) values than probability of inactivity (Pi) values, indicating potential antifungal activity. Among the tested compounds, β-sitosterol exhibited the highest Pa value (0.585) and the strongest binding affinity toward cutinase, with a binding energy of −7.1 kcal/mol and an inhibition constant (Ki) of 6.20 µM. These values were superior to those of the co-crystallized ligand (−4.8 kcal/mol; Ki = 301.60 µM) and the reference fungicide mancozeb (−3.2 kcal/mol; Ki = 4497.40 µM). Piperine and piperlonguminine also demonstrated strong binding affinities, with binding energies of −6.7 and −6.5 kcal/mol, respectively. The stability of the β-sitosterol–cutinase complex was primarily supported by hydrophobic and van der Waals interactions with key residues within the enzyme’s active site. Based on the in-silico analysis, β-sitosterol demonstrated the greatest potential as an inhibitor candidate among the compounds tested. However, these findings are predictive and require further validation through in vitro and in vivo studies to confirm its biological activity, efficacy, and safety.

Abstract

Maize (Zea mays L.) is an important food and feed crop in Indonesia, but production remains insufficient to meet rising demand. Inceptisols have good potential for maize cultivation; however, their low fertility and limited nitrogen (N) and phosphorus (P) availability restrict crop growth and yield. Although single and compound fertilizers are widely used, information on effective fertilizer combinations for improving nutrient availability and maize productivity in Inceptisols is still limited. This study evaluated combinations of single N, P, K fertilizers and NP granular fertilizer to improve soil fertility, nutrient uptake, chlorophyll content, and maize yield. A randomized complete block design with nine fertilizer treatments and three replications was applied. Treatments included an unfertilized control, recommended N, P, K, 100 kg ha⁻¹ NP granular fertilizer, and combinations of ¼–1 recommended N, P, K rates with 25–100 kg ha⁻¹ NP granular fertilizer. Soil nutrient availability, nutrient uptake, chlorophyll content, and yield components were analyzed using analysis of variance, Duncan’s multiple range test (5%), and correlation analysis. The combination of ¾ recommended N, P, K fertilizer with 75 kg ha-1 NP granular fertilizer produced comparable performance to the full recommended dose in enhancing nutrient availability, uptake, chlorophyll content, and yield, making it a highly efficient fertilization strategy for Inceptisols. The combination of ¾ recommended N, P, K fertilizer with 75 kg ha⁻¹ NP granular fertilizer produced the best overall performance, enhancing nutrient uptake, chlorophyll content, and maize yield, making it an effective fertilization strategy for Inceptisols.

Abstract

In 2023, an outbreak of viral disease on yardlong bean (Vigna unguiculata ssp. sesquipedalis) was reported in Tanjungsari District of Gunungkidul Regency, Indonesia. Symptomatic leaves showing mosaic, chlorosis, severe blistering, and leaf malformation were collected as a composite sample and then molecularly tested with RT-PCR. The sample was positive for potyvirus infection using U341/Poty1 universal primer pair, and BLAST analysis on the obtained nucleotide sequence further specified bean common mosaic virus (BCMV, Potyvirus phaseovulgaris) as the causal agent of the disease. Sequence of 691 bp of 3’-end region of BCMV-GKD-Ida isolate was registered in NCBI GenBank with accession no. PZ118702. The phylogenetic tree constructed using the Maximum Likelihood method with Tamura 3-parameter substitution model clustered BCMV-GKD-Ida with other BCMV isolates from 17 countries but in a distinct monophyletic branch. A paired identity analysis using the Sequence Demarcation Tool (SDT) software version 1.3 estimated that BCMV-GKD-Ida shares a fairly low nucleotide identity of 86.5%-92.5% with the compared BCMV isolates, further indicating considerable genetic variation. BCMV is one of most important plant pathogens that threaten the productivity legumes. This research provides additional molecular data and contributes a basis for early diagnosis and control strategies for the virus in yardlong bean.
