Abstract

Terasi paste consists of plant nutrients and microorganisms that potentially improve the health of plant seedlings. We evaluated the effects of terasi paste on seed germination, seedling growth, and root rot disease severity caused by Fusarium oxysporum f.sp. lactucae (FOL) in lettuce. Terasi paste was tested at four different weights (i.e., 0.00 g [T0], 1.00 g [T1], 2.50 g [T2], and 5.00 g [T3]) in the 100 g nursery soil. The results showed that lettuce seeds from T1 and T2 treatments were fully germinated, as observed for the T0 treatment. However, 40.0% of lettuce seeds from T3 treatment failed to germinate. Thus, 1.00 g and 2.50 g terasi applications in the 100 g soil did not affect lettuce seed germination. Moreover, T1 and T2 treatments tended to improve the shoot and root biomass of lettuce seedlings over T0 treatment, while T3 treatment showed the opposite effects. Following FOL infection, the lettuce seedlings from T2 and T3 treatments had 31.1% significantly lower disease severity than those from the T0 treatment. Therefore, T2 treatment (i.e., 2.50 g terasi application in the 100 g soil) imparts maximum health-promoting benefits to lettuce seedlings.

Abstract

Shallot (Allium cepa var. aggregatum L.) is an important commodity in horticulture and Indonesian foods. In Bantul Regency, Yogyakarta, Indonesia, shallot twisted diseases caused by Fusarium spp. significantly reduced yield quality and quantity. Supportive condition for plant-pathogen interaction needed for twisted disease development. This research aimed to measure the twisted disease incidence and observe the cultivation practice applied by shallot farmers in the Bantul coastal area as environmental aspects of the twisted disease to be a pre-study for further research on metagenomic analysis. This research had conducted in three sub-villages with different agroecosystems in the coastal area: Sono, Samiran, and Depok. Data were collected in shallot cultivation period in dry and rainy seasons from three farmers of each area. The higher disease incidence in the rainy season occurred in the Samiran sub-village at 33.97%, while in the dry season, disease incidence occurred in the Depok sub-village at 20.14%. Sono sub-village had the lowest disease incidence in rainy and dry seasons at 12.44% and 0%. Farmer cultivation practice may drive disease incidence due to environmental factors such as shallot variety, spacing between plants, fertilizer, and fungicides. Hence, further study is needed to understand plant-pathogen interaction with metagenomics through samples from 2 and 6 WAP in rainy seasons.

Abstract

Pest infestation is a major problem in corn cultivation because it causes a decrease in crop productivity or even crop failure. This study aimed to evaluate the level of crop damage caused by Helicoverpa armigera and Ostrinia furnacalis in three tropical altitude variations. Ten hybrid corns from cross-breeding strains and three commercial hybrid corn varieties were evaluated at three locations with different altitudes, classified as lowland (30 masl), midland (600 masl), and highland (1000 masl). The evaluation was carried out on the level of crop damage and plant resistance. The results showed that the highest percentage of H. armigera attack on hybrid corn was 75% at Caps 17B x Caps 23 (moderately susceptible) at the lowland and the lowest was 8% at Caps 2 x Caps 17A (resistant). The percentage of H. armigera attack was 100% at Caps 15 x Caps 22 (very susceptible) and the lowest was the evaluation of Caps 5 x Caps 17B was 58% (susceptible) at the midland. Meanwhile, the highest attack percentage was 92% on the Caps 17A x Caps 17B, Caps 17A x Caps 22, and Caps 5 x Caps 22 hybrids (very susceptible), while the lowest was 67% on the Caps 3 x Caps 17B and Secada hybrids (moderately susceptible) at the highland. O. furnacalis attack showed that all hybrid corns were classified as resistant except for Caps 5 x Caps 22 and Paragon was moderately resistant with a percentage attack of 25% at lowland. At the midland, Caps 5 x Caps 17B hybrid corn was classified as very susceptible with an attack of 92%, while Caps 15 x Caps 22 was classified as resistant with an attack percentage of 8%. At an altitude of 1000 masl, Caps 17A x Caps 17B, Caps 3 x Caps 17A, and Caps 5 x Caps 17B were moderately resistant with an attack percentage of 33% and other hybrids were resistant with an attack percentage of 8%.

Abstract

Robusta coffee is one of the plantation commodities vegetative propagated through cuttings to keep them in the same characteristics as their parents. The main problems in cuttings propagation are pests and diseases are cause damage to the planted cuttings. This research aimed to study the causal agent and its damage to robusta coffee cuttings planted on different media. The research was conducted from September 2020 to March 2021 in the experimental field station (KP) Pakuwon and the Integrated Laboratory of Balittri. The arrangement of the experimental design was a split plot with two repetitions. The main plot was the type of media planted consisting of sand, sand + fertilizer (1: 1), sand + soil (1: 1), soil + fertilizer (1: 1), sand + soil + fertilizer (1: 1: 1). The subplot was a Robusta coffee clone consisting of BP308, BP393, and SA203. The results showed that the highest percentage of damage caused by termites and Rhizoctonia sp. was observed on the cuttings planted on sand + fertilizer mixture media while the lowest was on sand media. The termites found in the robusta coffee cuttings were Macrotermes gilvus.

Abstract

The sorghum (Sorghum bicolor) plant is highly tolerant and adapted to drought. It has the potential to be developed and planted on marginal land in Indonesia. Tar spot disease is one of the obstacles to sorghum cultivation. In Indonesia, there is no report yet about this disease, especially on sorghum. To achieve optimal disease management, information on disease incidence and severity levels, as well as pathogen tar spot disease identification, are required. The aims of this study were to morphologically identify the pathogen and determine the level of incidence and severity of tar spot in sorghum cultivation areas in Bogor Regency, Gunung Kidul Regency, and West Lombok Regency. The disease observations were carried out on 17 sorghum varieties from the three areas with no experimental design. The results of the observation of the tar spot disease incidence in 17 varieties of sorghum from Bogor, Gunung Kidul, and West Lombok were 100%. The level of tar spot disease severity varied from 32.4% in the Latu Keta sorghum variety to the highest of 87.9% in the Samurai sorghum variety. The macroscopic and microscopic observation results of tar spot on sorghum plants showed that the cause of the tar spot disease was the Phyllachora fungi. This is the first report of a tar spot on sorghum caused by Phyllachora sp. in Indonesia.

Abstract

The xa13 gene is a recessive resistance gene against Xanthomonas oryzae pv. oryzae (Xoo) found in several rice varieties. Activation of this gene will trigger the formation of sucrose as a nutrient supply to Xoo for their growth in the plant. The disruption of this recessive gene expression in the plant can affect the negative impact of the gene, and recently can be created using clustered regularly interspaced short palindromic repeats (CRISPR) system using CRISPR-associated protein-9 (CRISPR/Cas9) technology that requires gRNA to recognize the targeted-sequence. This study aimed to design and construct the gRNA-targeting xa13 gene in rice using bioinformatics tools. CHOPCHOP was used for generated the gRNA candidates according to the target gene sequence. Two candidates of gRNA-targeted xa13 have been selected based on the analysis of bioinformatics data. Each candidate of gRNA consisted of 20 nucleotides (nt) of the target sequence upstream 3 nt of the protospacer adjacent motif (PAM) sequence (5’-NGG) targeting two exons in the xa13 gene. The gRNA1 will target exon 1 and the gRNA2 will target exon 2, with an efficiency of 52.51% and 44.63% respectively. Data showed that the GC content of all gRNA candidates ranged from 55–70% with no target-off location in the whole genome of rice. The transformation and confirmation test based on the physiological and genomic characteristics of transformants confirmed that the design has been successfully constructed.

Abstract

Rice dwarf disease caused by Rice grassy stunt virus (RGSV) and Rice ragged stunt virus (RRSV) is frequently found in Indonesia. This disease is transmitted by brown planthopper/BPH (Nilaparvata lugens Stål). The infected plants become dwarfs and lead to reduced yields. The purpose of this study is to determine the number of BPH populations due to the occurrences of dwarf disease and yield on Inpari 32 rice over two sequential planting seasons in Klaten, Central Java. The observed parameters were dwarf disease symptoms, incidence and intensity of the disease, BPH population and its natural enemy, the vegetative growth, and yields. The analysis used in this study were descriptive analysis and linear regression. The results showed that, plant growth during the dry season was better than the rainy season based on plant height and tiller number. The average population of BPH in the dry season were 0.2–4 individual/hill which is lower than in the rainy season (0.43–4.4 individual/hill). The incidence and intensity of disease in the dry season were lower than rainy season. The higher incidence and intensity of rice dwarf disease in the rainy season caused a decrease in dry harvest yields and milled dry yields were 10.95% and 10.81%, respectively

Abstract

Banana aphid Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae) is widely known as the main vector of Banana bunchy top virus (BBTV). It had been reported that banana aphid could live on alternative hosts belong to Family Araceae, and become important issue since Araceous plants are commonly found surrounding banana cultivations. Research had been conducted to study the morphometrics and biological characteristics of banana aphids living on various species of Araceous plants. The results showed that Araceous plant species could influence the morphometric and biological characteristic of banana aphids, indicated by the significant difference in some biological characteristics such as life cycle, life span, reproductive period, and fecundity. The average life span of banana aphids living on Araceous plants ranged from 22.80 to 47.90 days, it was shorter than the one that of lived on a banana plants. P. nigronervosa was able to develop a bigger colony when the aphid lived on Araceous plants, especially when they were transferred to Bogor taro where their fecundity reached 63 nymphs per female. Araceous plants also affected the morphometric of P. nigronervosa indicated by smaller size of the aphids, compared to those living on banana plant. The ability of banana aphid to live and reproduce in various Araceous plants would be beneficial to the development of control strategies of BBTV.

Abstract

In 2019 we found moss praying mantis around the forest in the Bedugul Area of Bali, Indonesia. This species belongs to the family Mantidae, subfamily Nanomantinae, and predicted as member of  Calofulcinia genus based on diagnostics of morphological characteristics, behavior, and habitat. Information about the morphological characteristics and data from the molecular sequencing database of the genus Calofulcinia has been very limited. In this research, the barcoding DNA of mitochondrial Cytochrome Oxidase I (mtCOI) of the species is noted using paired primers LCO1490 and HCO2198. Based on the sequence analysis (identity matrix and phylogeny analysis), the moss mantis from Bali has low similarity and genetic relationship with other Mantodea species from GenBank database. The data indicate the moss mantis from Bali has not been reported previously. In addition, the distribution of moss mantis species in Bedugul, Bali, Indonesia has just been described and recorded.

Abstract

Virus infection is one of the challenges in garlic production due to it perpetuates from one generation to the next and its infection caused huge yield reduction. There was still few information regarding virus status on Indonesian local garlic cultivars. This study was aimed to detect four major viruses infecting local garlic in Indonesia, they were members of genus Potyvirus (Onion yellow dwarf virus/OYDV, Leek yellow stripe virus/LYSV), and Carlavirus (Garlic common laten virus/ GCLV and Shallot latent virus/SLV). Garlic samples were obtained from IPB University collection and field survey in Tegal and Karanganyar (Central Java Province). Dot immuno-binding assay (DIBA) was done for initial virus indexing on non-commercial and commercial cultivars. Reverse transcription polymerase chain reaction (RT-PCR) using four specific primers was done to detect virus on commercial cultivars. DIBA from leaf samples showed that virus incidence of OYDV was relatively higher (92.3 to 100%) than GCLV and SLV (84.6 to 100%) from all tested cultivars. On average, ‘Lumbu Hijau’ has the lowest level of virus titter (severity) than other cultivars. The virus incidence of both bulbil and single clover was similar (97 – 100%) while virus titter of OYDV, GCLV, and SLV on bulbil was the lowest than other propagation materials. Detection by RT-PCR from two commercial cultivars showed that ‘Lumbu Hijau’ has less virus incidence than ‘Jawa Lama’. LYSV, OYDV, GCLV were detected on both cultivars but SLV was not found. Further virus indexing using larger number of samples and involving more virus targets needs to be done.
