Abstract

Papaya (Carica papaya L.) is an annual plant belonging to the Caricaceae family. Papaya populations in Indonesia can be found in almost all regions. The extensive papaya cultivation areas in Indonesia often involve planting on wild land, which exposes papaya plants to various diseases. Crown rot disease is an example of a disease in papaya. Papaya plantations in Jajag, Gambiran, Banyuwangi Regency, are known to be affected by stem rot. To determine the appropriate disease control measures, it is necessary to identify the cause of the wet rot disease in papaya plant stems. The research was conducted through several stages, including sampling, media preparation, isolation of pathogenic bacteria, hypersensitivity tests, pathogenicity tests, potato soft rot tests, colony and cell morphological observation, Gram staining, oxidative/fermentative, yellow colony on YDC media, lecithinase, catalase, sensitivity to erythromycin, carbohydrate fermentation, and temperature treatment at 37°C and 40°C. The results showed that the plant pathogenic bacteria causing crown rot at the base of the stem in papaya plants were isolates B1 and B2, belonging to the group of Pantoea sp.; isolates B3, B6, and B7, belonging to the group of Erwinia sp.; and isolates B4 and B5, belonging to the group of Dickeya sp..

Abstract

Cabbage (Brassica oleracea) is a vegetable crop with high commercial value in Indonesia. However, cabbage production still fails to meet consumer demand, with one of the causes being pest damage. Plant pest can be suppressed and controlled using natural enemies from various orders, including Coleoptera or beetles. Cultivation practices and landscape composition influence the presence of beetles. This study aims to investigate the characteristics of the landscape, the role of beetles, and the relationship between cultivation methods and landscape composition on the diversity, abundance, and composition of beetles. The research methods include determining the location and observation plots, mapping the landscape and characterizing the composition of the landscape, and setting traps for sampling, identification, and documentation. Data analysis used analysis of variance, analysis of similarity, and Generalized Linear Models (GLM). All data analyses were performed using RStudio software and the vegan package. Based on the research results, the dominant land use types are agriculture and natural habitats; beetles consist of predatory, herbivorous, decomposer, and scavenger beetles. Cultivation methods did not correlate with beetle diversity, abundance, and composition, whereas habitat conditions and landscape composition did correlate with beetle diversity, abundance, and composition.

Abstract

Coffee (Coffea sp.) is one of the leading commodities in the Indonesian plantation sector. The low productivity of coffee plants can be caused by several factors, one of which is the loss caused by the Coffee Fruit Borer (CFB) Hypothenemus hampei Ferr (Coleoptera: Scolytidae). This research aims to study the flowering phenology of coffee plants and the influence of different plant varieties on the phenology of the CFB. The research was conducted using an exploratory survey method and laboratory analysis. Based on the results, the phenology of H. hampei in each phase has different characteristics, and it was found that there is overlap in the phenology phases of coffee fruit, which causes the life cycle of H. hampei to remain uninterrupted throughout the year. The highest population of H. hampei was found in the BGN 371 compared to the BP cultivar.

Abstract

The tomato plant (Lycopersicum esculentum Mill.) is one of the horticultural crops that is frequently cultivated and consumed due to its considerable nutritional value, including vitamins A and C. In the cultivation process, farmers often face problems caused by plant pests, one of which is Thrips (Thrips palmi Karny). This study aims to determine the effectiveness of insecticides containing the active ingredients spirotetramat + abamectin at several concentrations against T. palmi. Research activities were conducted in Pujon District, Malang Regency, and Junrejo District, Batu City, East Java, from April to June 2023. The research used a Randomized Complete Block Design (RCBD) with 5 treatments: spirotetramat + abamectin 1.00 ml/l; 0.75 ml/l; 0.50 ml/l; 0.25 ml/l; and a control. The results showed that the use of spirotetramat + abamectin insecticides at different concentrations affected the average T. palmi population level and yield in tomato plants. Treatment with a concentration of 1.00 ml/l was the most effective, achieving an efficacy index (EI) value of more than 70%.

Abstract

The study was conducted in Ishiagu, Nigeria, to evaluate the impact of soil amendments on tomato Fusarium wilt management during the 2022 and 2023 cropping seasons. Eight (8) treatments were distributed in a randomized complete block design and replicated three times. Topsoil at a depth of 0 to 15 cm were collected before application of treatments to determine physico-chemical characteristics of the soil. The collected data were subjected to ANOVA, with means separated using Tukey at p < 0.05. The results showed that the application of treatments had a non-significant (p < 0.05) effect on the percentage disease incidence. The disease incidence was consistently highest in untreated plots, reaching 61.89% in 2022 and 68.76% in 2023, while treated plots showed the lowest incidence, with 18.87% in 2022 and 18.09% in 2023. Similarly, the result of the disease severity ranged from 2.00-4.67. Treated plots consistently yielded higher harvested weights across both years, with pig manure treatments achieving the highest results (1101.67 g in 2022 and 1088.33 g in 2023), while untreated plots had the lowest yields (191.33 g in 2022 and 405.67 g in 2023). Therefore, combined application of Gmelina ash and palm bunch ash as an organic amendment, could be an alternative means of managing the Fusarium wilt and increase the yield of tomato by the small-scale farmers.

Abstract

Lime is popular in Indonesia as an alternative treatment for cough and sore throat. Global production declined by 316,000 ton in 2021-2023 due to Citrus Tristeza Virus (CTV) attack, which is detrimental to citrus farmers. Effective preventive controls to suppress CTV attack include planting resistant varieties, insect vector control, cross-protection, and the use of Plant Growth Promoting Rhizobacteria (PGPR) or other beneficial microbes. This study aims to determine the effect of PGPR on the incubation period, intensity of CTV attack, chlorophyll content, and growth of lime seedlings. This research was conducted using a completely randomized design (CRD) with 8 treatments and 5 replications. The methods used were PGPR application and CTV inoculation on lime seedlings. The results showed that the application of PGPR Bacillus subtilis, Pseudomonas fluorescens, Azotobacter sp., and their combination was able to slow down the incubation period of CTV, suppress the intensity of CTV attack, and maintain the chlorophyll content of plant leaves due to CTV attack. However, the use of PGPR in this study has not been able to increase the growth of lime seedlings. Single PGPR has the same level of efficiency as the combination in suppressing the intensity of CTV attack.

Abstract

The Integrated Pest Management (IPM) program was implemented by the government from 1989-1998 through Integrated Pest Management Farmer Field School (IPM-FFS) activities. However, not all regions received this socialization. The uneven socialization activities regarding IPM have resulted in not all farmers having good knowledge about IPM and not all attitudes and actions taken by farmers are in accordance with IPM. Therefore it is necessary to study the evaluation of the level of success of the IPM program that has been implemented. The research was conducted in Purwoasri Village and Langlang Village by interviewing 20 farmers from each village with a questionnaire containing farmer characteristics, farming characteristics, knowledge, attitudes and actions of farmers in IPM. The data obtained was analyzed descriptively by simplifying the data to make it easier to interpret. The results of the research show that the IPM program in Purwoasri Village has been quite successful because IPM farmers are better than nonIPM farmers in terms of farming characteristics, knowledge, attitudes and actions in IPM.
