Unveiling the Best Growth Strategies: Chili Response to Plant Architecture and Growth Regulators Rini Murtiningsih, Wiwin Setiawati, Asih Kartasih Karjadi, Tonny Koestoni Moekasan, Neni Gunaeni, Eli Korlina, Bagus Kukuh Udiarto, Rasiska Tarigan, Erniawati Diningsih Acta Agrobotanica, 2026 Applying plant growth regulators (PGRs) and plant architectural modifications could improve the production of various crops. This study aimed to examine the effects of PGRs and modifications of plant architecture on plant growth, insect infestations, chili pepper productivity, postharvest quality, and seed production. A split-plot experiment with a randomized block design was carried out from July 2022 to February 2023 in West Java, Indonesia. The experimental treatments included several topically applied PGRs as sub plots and plant architecture as the main plots. Results showed that plant architecture-PGRs integration increased plant growth, yield, and yield characters, decreased insect infestation, and prevented post-harvest weight loss. The pruning crops grown in population density of 20,000 plants/ha and treated with 5 ppm Triacontanol and 50 ppm Naphthalene Acetic Acid experienced significantly improved fruit quality. The insect-caused crop damage decreased, with the range of the reduced fruit borer-caused damage were 6.7 to 11.3 % and the decline of oriental fruit flies-caused crop damages were 1.25 to 9.82 %. Combining plant architecture with plant growth regulators is an innovative and environmentally friendly way to increase chili pepper yields and help meet the world's growing food needs.
Field Resistance Status of Hot Pepper to the Pepper Yellow Leaf Curl Indonesian Virus in Relation to Volatile Compounds Puspita Deswina, Rinda Kirana, Karden Mulya, Neni Gunaeni, Sobir Sobir, Dani Satyawan, Kristianto Nugroho, Rerenstradika Tizar Terryana, Dyah Manohara, Darkam Musaddad, Imas Rita Saadah, Tonny Koestoni Moekasan Sains Malaysiana, 2025 The Pepper Yellow Leaf Curl Indonesian (PYLCI) virus, transmitted by the whitefly, has a significantly detrimental impacts on the productivity of hot peppers. Despite the implementation of extensive breeding programs, the development of varieties resistant to PYLCI remains a challenging endeavor. This study proposes a novel strategy that considers vector-host interactions with the objective of enhancing resistance. A total of 37 genotypes of hot pepper, collected by IPB University and the National Research and Innovation Agency (NRIA), along with two registered varieties of hot pepper (Bonita and Sigantung), were utilized in this study. The results were classified into five categories based on the disease reaction observed in the tested genotypes. The IPB RF 41 genotype exhibited high resistance, with no instances of diseases and minimal symptom intensity. In contrast, the IPB RF 20 genotype demonstrated high susceptibility, with a 64% incidence of disease and a symptom intensity of 41.85%. The distribution of the whitefly was consistent across the area, with an average of 29–39 imagos per week in each trap. The flowers and leaves of the CR-2022-46 (resistant) and IPB RF 29 (susceptible) genotypes were found to contain volatile compounds. The resistant genotypes exhibited a reduced number of volatile floral compounds. Leaf analysis showed the presence of D-limonene, indole, naphthalene, 1.4.5-trimethyl-, whereas these compounds were not detected in the flowers. Conversely, α-fenchene and naphthalene, 2-methyl-, were found exclusively in the flowers. Beta-ocimene plays a role in the whitefly-hot pepper interaction, with varying patterns of increasing from the vegetative to generative phases between resistant and susceptible genotypes. Resistant plants released higher levels of (E)-4,8-Dimethylnona-1,3,7-triene (DMNT) in both phases. This information could prove beneficial for the further development of alternative breeding programs focused on PYLCI resistance, and potentially revolutionize the agricultural practices in Indonesia.
Light traps based-control threshold: An alternative method for hot pepper pests’ management Rini Murtiningsih, Tonny K. Moekasan, Laksminiwati Prabaningrum, N. Gunadi, Wiwin Setiawati, et al. Chilean Journal of Agricultural Research, 2024 Crop damage-based control threshold of 12.5% has been used to reduce the excessive use of insecticides while controlling Spodoptera litura and Helicoverpa armigera in hot peppers (Capsicum annuum L.) cultivation systems.However, it is necessary to develop an easy, practical, inexpensive control threshold to increase farmer eagerness in reducing pesticide use.The study aimed to evaluate a light trap captured based-control threshold for both hot pepper pests.The activity was conducted at Lembang (ca.1250 m a.s.l.), West Java, Indonesia, from September 2022 to April 2023.Six treatments and four replicates were arranged in a randomized block design.The treatments included the use of four light trap captured based-control thresholds, i.e., 30, 25, 20, and 15 moth trap -1 wk -1 ; crop damage based-control threshold of 12.5%; and once per week insecticide application as a control treatment.The study found that the implementation of pests' control threshold of 25 moth trap -1 wk -1 could reduce 75% insecticide use compared to the plant damage-based control threshold.The use of this approach could maintain high crop production and generate a return rate of 1.26.The findings will be beneficial for farmers in reducing insecticide use.
Bio-rational Pesticide Approaches, Environmentally Safe Methods for Controlling Pests and Diseases in Garlic Crop Bagus K. Udiarto, Wiwin Setiawati, R. S. Basuki, R. Murtiningsih, L. Prabaningrum, T. K. Moekasan, A. Hasyim Aip Conference Proceedings, 2024 Conventional pesticides are highly toxic to many living organisms as well as to the environment from pesticide pollution, which is a global problem. These have created public awareness of human safety and possible environmental damage diverting attention towards other alternatives especially the use of bio-rational pesticides. In the present study, some botanical products have been evaluated against pests and disease infestation associated with garlic crops. The experimental setup was a Randomized Complete Block Design (RCBD) with four replications. Six botanical treatments and conventional pesticides were applied i.e. A) Tigonal (aqueous extracts); B) Tigonal plus (aqueous extracts); C) Teprogonal (aqueous extracts); D) Teprogonal plus (aqueous extracts); E) Tigonal (methanol extracts); F) Teprogonal (methanol extracts); and G) Synthetic chemical pesticides (conventional pesticides). There were significant reductions of pests and diseases on garlic crops such as thrips, leaf miners, Alternaria leaf spot, and Stemphylium leaf blight in all the botanical treatments applied by aqueous extracts (P<0.05), with the efficacy close to that of conventional pesticides. Under field conditions, methanol extracts of Tigonal and Teprogonal were highly effective in reducing the population of T. tabaci and Liriomyza sp. up to 40–52% and reduction of disease incidence and severity around 53.30–90.14% in both cases than those of conventional pesticides. It is obvious from the results that the use of Tigonal (methanol extracts) could be effectively considered as a pests' management option to reduce this serious pest and disease infestations and increase garlic productivity by 6.39%.
The Potential of Light and Pheromone Traps for Controlling Main Pests in Cabbage Rasiska Tarigan, Ali Asgar, Tonny Koestoni Moekasan, Laksminiwati Prabaningrum, Rina C. Hutabarat, Agustina E. Marpaung, Rini Rosliani, Bina Br Karo, Dewi Sartika Aryani Aip Conference Proceedings, 2024 Cabbage (Brassica oleraceae L.) has a strong potential to grow and to meet domestic needs. Cabbage has also the possibility to be exported. It is a grievous fact that the cabbage production fails to meet the increasing demands in national and international markets. The damage caused by pest attacks is considered a major concern. Therefore, in this research, we examined the efficacy of controlling pests using light and pheromone traps. The objective was to evaluate its efficiency in controlling several main pests in cabbage. Employing Randomized Block Design Non-Factorial, these treatments consisted of LED-light trap (P1), sex-pheromone of Crocidolomia binotalis (P2), and sex-pheromone of Plutella xylostella (P3). Each treatment was replicated three times. Independent 10 traps/ha were applied for each treatment. The results revealed the application of light traps efficiently controlled a higher number of cabbage P. xylostella and C. binotalis compared to sex pheromones traps at vegetative and generative stages of plant growth. The light trap caught both sexes of pests, lowering their population in the field and reducing their possibility of mating and reproducing new generations. The average number of insects captured, eggs, and larvae were high, causing lower plant damage, resulting in plants performing well and producing better yield (1.75 kg) compared to plants with sex pheromone traps (1.18 and 0.92 kgs).
Intercropping insect repellent plants (irps): a promising strategy for sustainable pest management Gunaeni, N., Setiawati, W., Muharam, A., Karjadi, A.K., Murtiningsih, R., et al. Agronomy Research, 2024 In current intensive crop production, the utilization of natural biological control in pest management is not fully maximized, resulting in a significant dependency on the application of insecticides. Insect-repellent plants (IRPs) have become a prominent subject of research and a widely implemented strategy for reducing both pest damage and reliance on chemical insecticides. In this study, intercropping three IRP species, coriander (Coriandrum sativum L.; Apiaceae), celery (Apium graveolens L.; Apiaceae), and bunching onion (Allium fistulosum l.; Amaryllidaceae), in two intercropping systems were assessed for controlling insect pests in chilli pepper. The research was carried out in the experimental field of the Indonesian Vegetable Research Institute (IVegRI) in 2022. The results revealed that intercropping systems of chilli pepper with coriander, celery, and bunching onion significantly reduced plant damage over sole crops. Among the various intercrop combinations, chili pepper intercropped with coriander resulted in the lowest damage of three major pest species on chili pepper, Thrips parvispinus (51.77%), Helicoverpa armigera (47.67%), and Bactrocera dorsalis (40.35%). Furthermore, this effect enhanced the productivity of chili pepper yield (43.27%).
Technical feasibility and economic benefit of combined shallot seedlings techniques in Indonesia Rini Rosliani, Chotimatul Azmi, Asma Sembiring, Rini Murtiningsih, Meksy Dianawati, Suwarni Tri Rahayu, Ineu Sulastrini, Neni Gunaeni, Tonny K. Moekasan, Darkam Musaddad, Rinda Kirana, Shinta Hartanto, Ade Dahlan Santosa, Harmanto Harmanto Open Agriculture, 2024 One of the important factors in the success of True Seed of Shallot (TSS)-based shallot production is the right seeding technology. The study aimed to obtain appropriate nursery techniques for producing high-quality seedlings to increase shallot productivity. The experiment was conducted in Cirebon Regency, West Java, Indonesia, from May to October 2021, using a factorial randomized block design with three treatment factors and three replications. They consisted of shallot varieties (V) (Trisula, Bima, Lokananta, and Maserati); seedlings age (U) (45 and 60 days); and seedling population density (P) (5, 7.5, and 10 g m−2 of TSS). The results revealed that seedling performance was negatively correlated to the bulb yield and revenue cost ratio (R/C). The use of young seedlings enhanced bulb production and R/C ratio in all varieties but had varied effects on cluster alterations in Maserati, Bima, and Trisula varieties. Young Lokananta seedlings prepared in the nursery at a seed density of 7.5 g m−2 proved to be the best treatment to generate the highest bulb production (39.92 t ha−1) and the highest R/C (3.62). Farmers are expected to implement seedling preparation techniques using young seedlings and managing seed populations in diverse varieties to maximize bulb production and R/C.
Preferences and functional response of Coccinellidae to Bemisia tabaci (Hemiptera: Aleyrodidae) Bagus K. Udiarto, Rini Murtiningsih, Agus Muharam, Tonny K. Moekasan, Wiwin Setiawati, Ahsol Hasyim, Ineu Sulastrini, Neni Gunaeni, Eli Korlina, Nikardi Gunadi, Trilaksmi Udiati, Tateki Y. Tursilarini, Abdi Negara, Asni Ardjanhar, Ifa Manzila Chilean Journal of Agricultural Research, 2023 An exploration study found that 4 out of 11 predominant predator species of Bemisia tabaci in Indonesia belong to Order Coleoptera, family Coccinellidae, i.e., Menochilus sexmaculatus, Coccinella transversalis, Verania lineata, and Curinus coeruleus. The current study was conducted to further determine the most effective predator species among those coccinellids. The evaluation included three consecutive assays, i.e., predation, preference, and functional response assay. The experiments were conducted in 2019 under controlled conditions in West Java. Predation assay using B. tabaci as the prey showed that M. sexmaculatus, C. transversalis, and V. lineata had comparable predation capacity to consume 46-48 nymphs d-1 or 9 adults d-1, and the V. lineata preference to B. tabaci was higher compared to other predators. Further logistic regression analysis (linear coefficient P1 = -0.1006, X2 = 34.99) showed that V. lineata had type II functional response characteristics. The analysis using the Hollings disc equation for type II functional response (R2 = 0.9239) suggested that the searching rate (a) and the handling time (Th) of V. lineata to B. tabaci nymphs were 0.3522 h-1 and 0.151 h, respectively. These results indicate that V. lineata could be considered in pest management strategies and effectively regulate populations of B. tabaci in Indonesia.
