Abstract

The main product of the palm plant is sap, which results from tapping the male flowers into palm sugar, soft drinks, vinegar, and alcohol. Apart from that, sugar palm plants can also produce food products such as palm fruit from female fruit, sugar palm flour for food in the form of cakes, bread, and biscuits, which comes from processing the pith of the plant stem and can be used as a source of bioethanol production.  However, there is limited research on how sugar palm agroecosystems influence the dynamics of herbivorous pests and predatory insect populations, making it essential to understand these interactions for sustainable plantation management. This research aimed to study the influence of sugar palm agroecosystems on the presence of herbivorous insect pests and predatory. The research was conducted in Nagari Labuah Gunung, Lima Puluh Kota Regency, West Sumatra Province. Observations were conducted on stretches of sugar palm plants aged 7-8 years or already producing. The sample plants were determined using purposive sampling, and labels were given to each tree that was part of the sample plants. Identify herbivorous and predatory insects obtained from the field and calculate the attack level. From the research carried out, it was found that management of sugar palm plants affects the presence of herbivorous and predatory insect pests, where no herbivorous insect pests were found on sugar palm plantations, and no herbivorous insect pest attacks were found on sugar palm plants on people's plantation land. Many types of predatory insects are found in sugar palm plantations, including Hymenoptera, Coleoptera, Orthoptera, Mantodea, Dermaptera, and Diptera.  These findings contribute to a deeper understanding of the ecological balance within sugar palm agroecosystems, emphasizing the potential role of natural predators in maintaining pest-free plantations and supporting sustainable agricultural practices.

Abstract

Weed control is one of the determining factors for achieving high oil palm yields, at the same time fertilization is necessary to provide nutrients for plants. This study aims to: (1) determine the interaction between the herbicide IPA Glyphosate with fertilizer Urea+SP-36+KCl on weed control and growth of immature oil palm. (2) to obtain an effective dose of herbicide to control weeds, and to obtain the best dose of Urea+SP-36+KCl fertilizer for the growth of oil palm. The study was conducted using a factorial Randomized Block Design (RBD) consisting of 2 factors and 8 treatment combinations. The first factor is herbicide doses of IPA Glyphosate (1,920 g/ ha, 2,400 g/ha, mechanical weeding, and control) and the second-factor is fertilizer doses of Urea+SP-36+KCl (600 g Urea +750 g SP-36 +700 g KCl/plant, and 700 g Urea + 850 g SP- 36 + 800 g KCl/plant). The data were analyzed for variance and if significantly different then continued with Duncan’s New Multiple Range Test (DMNRT) at the 5% level. The results showed that there was no interaction between the dose of the herbicide IPA Glyphosate with fertilizer Urea+SP-36+KCl on weed control and growth of immature oil palm. The herbicide dose of I PA Glyphosate which was effective in suppressing the dry weight of weeds was 1,920 g/ha because it was effective in suppressing the dry weight of weeds up to 12 weeks after application (WAA) and obtained the smallest average of weed dry weight. Urea+SP-36+KCl fertilizer application did not affect the vegetative growth parameters of immature oil palm.

Abstract

Setothosea asigna poses a significant threat to oil palm plantations, necessitating effective control measures. This survey-based research, utilizing Purposive Sampling, identifies parasitoids and evaluates their effectiveness in Dharmasraya oil palm plantations, a crucial palm oil-producing region in Indonesia. The selected criteria encompass plantations aged 6-15 years with a considerable Setothosea asigna infestation, providing a comprehensive overview of the pest's impact. The study establishes five sample points diagonally, each comprising five randomly chosen plants, totaling 25 samples per site, ensuring diverse representation. The predominant larval parasitoids exhibit noteworthy efficacy, primarily from the Hymenoptera order, Braconidae family, Genus Apanteles, and Spinaria. Among the 110 larvae observed, five were parasitized, resulting in the emergence of 65 parasitoids. The parasitization rate varies from 0 - 9.09%, with prominent contributions from Apanteles sp. and Spinaria sp., belonging to the endoparasitoid type. This research significantly contributes to sustainable agriculture practices and the palm oil industry, offering insights into targeted pest control for Setothosea asigna. Despite its focus on Dharmasraya, the study provides a valuable foundation for broader applications and invites further research for generalization.

Abstract

Crop diseases caused by fungal infections have significantly impacted cocoa production, leading to substantial economic losses due to ineffective disease management strategies. Leaf spot disease, in particular, threatens cocoa yield and quality, necessitating accurate identification of its causal agents for effective control measures. This study aimed to isolate, identify, and assess the pathogenicity of fungal species associated with cocoa leaf spot disease. A total of 45 microfungal isolates were obtained from infected cocoa leaves and identified to the genus level, including Aspergillus, Clonostachys, Colletotrichum, Curvularia, Diaporthe, Fusarium, Lasiodiplodia, and Nigrospora species. Pathogenicity tests revealed that 12 isolates induced lesions on cocoa leaves, confirming their pathogenic potential. Molecular identification using internal transcribed spacer (ITS) sequence analysis verified the species identity of the pathogenic isolates, with Lasiodiplodia theobromae (B3418) exhibiting the highest virulence, producing lesions of 3.17 ± 0.76 mm. These findings highlight the diverse pathogenic fungi associated with cocoa leaf spot disease. This study provides valuable insights into fungal pathogenicity and can contribute to the development of effective disease management strategies, which can reduce fungal infections and improving cocoa productivity.

Abstract

Spodoptera exigua is the primary pest attacking shallot plants from the vegetative to the generative phase. Yield loss caused by S. exigua attack can reach 57%. Rhizobacteria have been known to be used as biocontrol agents for controlling insect pests. The research objectives were to determine and compare the effectiveness of Yuyaos and BPTPH rhizobacteria formula (Bacillus sp.) in suppressing the attack of S. exigua on shallot-growing areas. The study used a completely randomized design (CRD) of 3 treatments and five replications. The treatment consisted of shallot seedlings treated with two types of rhizobacteria (Yuyaos and BPTPH) and water (without rhizobacteria) as control before planting. Beneficial effects of the rhizobacteria on shallot plants were observed in the following variables, including the development of the S. exigua population, damage level of S. exigua, and shallot growth. The results showed that introducing Yuyaos rhizobacteria (RZ2.1AG1, Bacillus thuringiensis), which originated from the rhizosphere of the chili plant, was the best way to protect shallot plants from S.exigua. Effectively reduced the population of S.exigua (78.90%), leaf damage (62.12%), and damage intensity (38.88%). On the other hand, Yuyaos was also influential in increasing tuber growth (11.11%), plant height (43.29%), number of leaves (58.33%), and number of tillers (22.22%).
