Abstract

This research aims to study the effectiveness of the fungus Purpureocillium lillacinum as a control agent for root-knot nematodes and its potential as an endophyte in tomato plants. The study was conducted from August 2023 until Februaty 2024 in the greenhouse of the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The experiment followed a Completely Randomized Design (CRD) consisting of five treatments with five replications. The treatments tested were different dosage levels of P. lilacinum fungus culture on rice; 5g, 10g, 20g, 20g, 40g and 0g per polybag containing 2.5 kg of planting medium. P. lilacinum was applied by spreading it on the planting medium and soaking the roots in a suspension of fungal conidia before transplanting. Seven days after transplanting, the tomato plants were infested with 2000 root-knot nematode (RKN) Meloidogyne sp. eggs. Ninety days after planting, the plants were harvested to observe nematode populations in the roots and soil, root damage, and fungal colonization in the roots. Nematode (J2) in roots were extracted using a modified Baerman method from 5g of root samples, while nematode (J2) in the soil were extraced by sieving and sentrifugation with a sugar solution from 300 cc of soil. Root damage was assessed using a root gall score 0-10, and fungal colonies in the roots was expressed as a percentage after staining using tryphan blue. Data were analyzed for variance and followed by the Least Significant Difference (LSD) test for at a 5% significance level. The results showed that the application P. lilacinum at 40 g per plant was effective in reducing root-knot nematode damage, as well as decreasing RKN (J2) populations in the soil and roots. Additionally, P. lilacinum was confirmed to be endophyte in tomato plants.

Abstract

Corn (Zea mays L.) is an annual cereal crop that has high economic value and has the potential to be developed in Indonesia. However, corn production can be hindered due to the attack of caterpillar pests (Spodoptera frugiperda J.E Smith). The fall armyworm attacks the young leaves of corn plants which can cause the failure of leaf shoot formation. However, the attack can be controlled by using plant-based pesticides. One of the plants that can be used as a plant-based pesticide is tobacco leaves (Nicotiana tabacum L.). This study aims to determine the effect of several consentration of  tobacco leaf extract on the mortality of fall armyworm  in vitro as well as to determine LC50 from all S. frugiperda test larvae that have been treated with tobacco leaf extract. This research was carried out in January-June 2024 at the Plant Pest Science and Biotechnology Laboratory, Department of Plant Protection, Faculty of Agriculture, Lampung University. This study uses Randomized Group Design (RAK) for the basis of grouping with 6 treatments and 4 replications. Tobacco leaf extract used in this study were:   0% (control), 0,5% (T1), 1% (T2), 1,5% (T3), 2% (T4), 2,5% (T5) with 4 replications so that 24  experimental units were obtained, each experimental unit was in the form of 10 instar larvae of 3 corn caterpillars. The results of this study showed that the use of tobacco leaf extract at concentrations of 1,5%, 2%, and 2,5% caused mortality of 100% for 30 days of observation.

Abstract

Many studies have shown that botanical pesticides are safe for controlling pest problems in the field. Arenga fruit paste has been suggested to contain secondary metabolites that can help manage golden apple snail infestation. The objective of this research was to determine the effect of arenga fruit paste application on the feeding activity and mortality of golden apple snails. This study used a completely randomized design with different treatment concentrations of arenga fruit paste, namely 0, 1, 2, 4, 6 g per L of living medium, with four replications. The results showed that the application of arenga fruit paste decreased feeding activity and increased mortality of golden apple snails. At the highest concentration, 6 g per L of live medium, food consumption was reduced to only 10%, resulting in the highest mortality rate of 80%.

Abstract

This study aims to determine the percentage of the presence of fungi associated with processed coffee beans that freshly harvested and those that have been stored for 6 months and identify the fungi found at least to the genus level. This research was conducted from July to September 2021 at the Agricultural Biotechnology Laboratory, Faculty of Agriculture, University of Lampung. The method used was a survey method. Coffee beans samples were taken in Sedayu Village, Semaka District, Tanggamus Regency. Samples of coffee beans were taken at different season, namely in October 2020 and April 2021. The types of processed coffee that would be identified were natural, honey and lowgrade. The method used in this study was the direct plating method using PSA (Potato Sucrose Agar) media and repeated 5 times by putting 5 coffee beans in each petri dish. The variables in this study were identification of fungi based on their macroscopic and microscopic properties and analysis of  index diversity. The results showed that as many as six fungi were found to be associated with coffee beans, namely, Aspergillus niger, Aspergillus fumigatus, Aspergillus flavus, Aspergillus parasiticus, Phytophthora sp. and Penicillium sp. The most commonly species was found, Aspergillus niger, which was 64% found in processed coffee from the 2021 harvest year. The result of the analysis show that the fungi diversity index (H’) of low grade coffee beans in the 2020 harvest season and natural processed 2021 classified as moderate diversity (1 ≤ H’ ≤ 3). While, other processed products are classified as low diversity (H < 1).

Abstract

Downy mildew is one of the main diseases in maize which can reduce production. The objectives of this study were to determine the effect of phosphorous acid, dimetomorph, and metalaxyl fungicides on the germination and tube length of Peronosclerospora maydis conidia and the effect of phosphorous acid, dimetomorph, and metalaxyl fungicide treatment on conidia on the intensity of downy mildew in plants inoculated with these conidia. This study consisted of two tests, i.e., in vitro tests (effect on conidia germination and tube length) and in vivo tests (effect on downy mildew intensity). In both tests, a randomized block design (RBD) was used with four treatments and six replications. The results showed that phosphorous acid and dimethomorph fungicides inhibitted germination and reduced the length of conidia sprout tubes and suppressed downy mildew intensity. Meanwhile, metalaxyl fungicide was not effective in suppressing germination and conidia tube length and the intensity of downy mildew.

Abstract

Begomoviruses are a group of plant viruses belonging to the Geminiviridae family, persistently transmitted by the whitefly Bemisia tabaci, and pose a serious threat to horticultural crops in Lampung Province, Indonesia. These viruses infection symptoms such as mosaic, chlorosis, leaf curling, and stunted growth, with yield losses reaching up to 90%. The spread is exacerbated by intensive cultivation practices, the use of uncertified seeds, and tropical climates that favor high vector populations. This study explores the biological characteristics of Begomoviruses, their transmission mechanisms via vectors, and their high genetic variability due to frequent mutation and recombination. Several begomovirus species have been identified infecting key horticultural crops in Lampung, including Ageratum yellow vein virus (AYVV), Tomato yellow leaf curl Kanchanaburi virus (TYLCKaV), and Pepper yellow leaf curl Indonesia virus (PepYLCIV). In addition to vector transmission, some begomovirus species are also known to be seed-transmitted, expanding their epidemic potential. Integrated management strategies discussed in this article include the use of resistant varieties, biological and agronomic control of vectors, and the development of innovative approaches such as mild strain cross-protection. This review emphasizes the need for continuous monitoring and science-based sustainable strategies to mitigate the impact of Begomoviruses on food security and horticultural productivity in tropical regions such as Lampung.

Abstract

Leaf diseases in banana seedlings is one of the most serious problem in PT GGF because the cost of post-planting field control will be very high if disease control in the nursery is not effective. This study aims to determine banana leaf diseases caused by fungi in nurseries at PT GGF, the efficacy of seven fungicide active ingredients to control banana leaf diseases in nurseries, and the cost of controlling leaf diseases on the health of banana seedlings in nurseries. The research was conducted from February to September 2024 at GGF in Central Lampung. Disease diagnosis is carried out by taking samples of leaves of banana seedlings with spotting or other symptoms and following Koch’s postulates. In the efficacy trial of seven fungicide active ingredients, the treatments were arranged using a completely randomized design (RAL) with nine treatments and two replications. Efficacy test were conducted using two treatments that differed in the way the fungicides were applied. The observed variables were disease incidence, healthy leaf rate, and average number of leaves per plant to determine the cost of control on banana seedling health. The results showed that pathogenic on banana seedlings, namely Fusarium, Curvularia, Nigrospora, and several fungi that have not been identified. The efficacy test of seven fungicide active ingredients in the control treatment was significantly different from captan, tiram liquid, tiram powder, and mancozeb so that several kinds of fungicide active ingredients can be used as alternative fungicides to control freckles on banana seedling leaves which can then be tested further. The cost of disease control per seedling was found to be between Rp1.190-1.210, but this cost did not provide any control over seedling health.

Abstract

Bleeding disease in tangerine plants is caused by the fungus Botryodiplodia theobromae. This study aimed to determine the effect of Cyperus rotundus L. extract on the growth of B. theobromae mycelia and spores in vitro, and to determine the best concentration of C. rotundus extract in inhibiting the growth of the fungus. The study was conducted using a Completely Randomized Design (CRD) consisting of 7 treatments, namely C. rotundus extract concentrations of 0.0% (control), 0.1%, 0.2%, 0.3%, 0.4%, and 0.5%, as well as a fungicide treatment containing the active ingredient carbendazim 0.1%. The observed variable was fungal growth measured by colony diameter. The results showed that the treatment of sedge rhizome extract was able to suppress the development of B. theobromae fungal colonies. This nutmeg rhizome extract has the potential to be developed as a botanical pesticide to control B. theobromae fungus, and a concentration of 0.5% nutmeg rhizome extract has the highest inhibitory power against the growth of B. theobromae fungus, namely 56%.
