Abstract

Plant-parasitic nematodes are one of the causes of yield loss in potato cultivation. Currently, information on the diversity, abundance, and dominance of potato parasitic nematode genera is not available. This research aimed to determine the pattern of distribution, abundance, and dominance of parasitic nematode genera on potato plant (Solanum tuberosum) in Wonosobo and Banjarnegara Districts at various altitudes i.e.: 1,250–1,500; 1,500–1,750; 1,750–2,000; and 2,000–2,250 meters above sea level (m.a.s.l.). Soil rhizosphere and root samples were collected, and nematodes were extracted using the Whitehead tray modification technique. The nematodes were adjusted with Formalin Acetic acid Alchohol (FAA), mounted, and identified based on morphological characters. The diversity index was determined to distinguish plant-parasitic nematode diversity. Six genera of potato plant-parasitic nematodes were found, namely Meloidogyne, Hirschmanniella, Globodera, Criconemoides, Helicotylenchus, and Xiphinema. The highest population of plant-parasitic nematodes was found at 1,250–1,500 m.a.s.l. from both root and soil samples. The nematode populations were 56.67 nematodes/5 g root and 103.33 nematodes/100 g of soil. The abundance of parasitic nematodes did not differ significantly among different altitudes in both districts. The dominant parasitic nematodes in soil samples were Meloidogyne with 16.78%, while Globodera was 13.98%. The Shannon-Wiener index implied that the diversity of parasitic nematodes of potato plants and stability of community in Wonosobo and Banjarnegara Districts were categorized as low.

Abstract

This survey was done in several guava fields around Bogor and found many unhealthy plants infested by various plant pests and diseases. This study aimed to analyze the effect of various guava cultivars on pest and disease intensity on guava in the Sub-District of Tanah Sareal, Bogor. Samples were collected from 20 fields that consisted of 15 samples of Getas Merah and 5 samples of Bangkok Putih cultivars to identify plant pests and diseases. Interviews were done with field owners to obtain information on cultivating practices. Pests found based on morphological identification included plant bugs (Hemiptera: Miridae), locusts (Orthoptera: Acrididae), bagworms (Lepidoptera: Psychidae), Geometrid caterpillars (Lepidoptera: Geometridae), Pyralid caterpillars (Lepidoptera: Pyralidae), scale insects (Hemiptera: Coccidae), planthoppers (Hemiptera: Flatidae), and mealybugs (Hemiptera: Pseudococcidae). Disease and pathogens identified included red rust disease (Cephaleuros sp.), anthracnose (Colletotrichum gloeosporioides), and fruit cancer (Pestalotia sp.). The occurrence of biting-chewing type pests was greater than piercing-sucking type insects, including 33.33% and 34.99%. Red rust disease was the dominant disease found on both guava cultivars consisting of 68.88% and 63.33% of the samples.

Abstract

Paraquat dichloride is a herbicide compound commonly used to control grasses and broadleaf weeds. Its use is presently under scrutiny as there is a report that this herbicide is very harmful and hazardous to the environment, especially to wild fauna surrounding farming sites. An irrigated rice farming locale experiment was conducted to observe the effect of paraquat treatment on rice plant biotic environment, particularly its arthropods and earthworm population, two of the most prominent fauna easily affected by paraquat. The study was carried out in Seyegan District, Sleman Regency, Special Region of Yogyakarta Province, on irrigated rice land from October 2018 to February 2019. Four treatments of paraquat, i.e. control (0 kg/ha paraquat), lower dose (0.8 kg/ha), medium dose (1.6 kg/ha), and higher dose (3.2 kg/ha) were arranged. Carbendazim 5 kg/ha was also applied as comparing pesticides, especially for paraquat’s effect on the earthworm. The treatments were replicated five times in a plot of 5 x 5 m2. The number of arthropods and earthworms was observed in about two weeks intervals or more. The observation was done for the number of arthropods and their families, while for earthworms, only for their numbers. The arthropods population data were subjected to diversity indices and statistical analysis, while the earthworms data were statistically analyzed. The result showed that the arthropod numbers in treated plots were statistically significantly different, but biologically their number was still abundant. Their diversity did not differ from the control treatment at all. The arthropod numbers were 2007, 1483, 1095, 1746, and 1204 in control, lower, medium, higher, and carbendazim plots. The earthworms' numbers were still plenty; those in the higher dosage did not differ significantly from those in control. Their numbers from control, lower, medium, higher dose, and carbendazim plots were 811, 658, 567, 882, and 445 individual earthworms.

Abstract

Plant pests and diseases cause decreases in strawberry yield in Bali, including plant viruses. Strawberry vein banding virus (SVBV) is a virus that infects strawberry plants and is transmitted by insects. However, studies about this disease in Bali are still limited. This study aimed to detect SVBV within insect bodies and determine the insect species of its vector. Methods used included (1) sampling; (2) detection of SVBV from insect bodies using primers (SVBV F/SVBV R) and PCR; and (3) molecular identification of viruliferous insect with primers (LCO 1490 F/HCO 2198 R) using PCR and sequencing analysis. This study successfully detected SVBV DNA in an insect from three insect families associated with strawberry plants in Pancasari Village, Buleleng Regency, Bali. Results from the nucleotide sequences analysis in SVBV viruliferous insects indicate that the insect was Myzus persicae.

Abstract

Corn is one of Indonesia's agricultural products with economical and strategic value and many potential to develop, such as carbohydrates and protein sources. There are two types of beneficial insects in corn production: predators and parasitoids. This study aims to identify the diversity of beneficial insects in corn plantations. This study was conducted from May to September 2019 in four different locations across West Sumatra, namely Padang Pariaman, West Pasaman, Pesisir Selatan, Solok Regencies. Identification of beneficial insects was made in Entomology Laboratory, Faculty of Agriculture, Andalas University. This study adopted a purposive sampling method using 20 sweeps of sweep nets, following a transect line of cornfields. The result showed five orders, 34 families, 101 morphospecies, and 747 beneficial insects in all locations. The diversity in each location varies from high, medium, and low. In all areas, the diversity index was high, with the criteria of ≥ 2.90, implying that the condition of the community structure was very stable. From the evenness index analysis, three locations were classified as high, and the other one was moderate. These three sites were Padang Pariaman, West Pasaman, and Solok, with criteria of ≥ 0.90 and very stable distribution conditions.

Abstract

Various viruses can cause mosaic disease on tobacco plants. Proper detection of the cause of the mosaic disease helps determine effective control. The purpose of this study was to detect the presence of double infection of Rehmannia mosaic virus (ReMV) with Potato virus Y (PVY) using multiplex RT-PCR in tobacco plants from Central Java and Special Region of Yogyakarta. The viral suspension was inoculated on Chenopodium amaranticolor to obtain one viral colony from one local lesion. The multiplex RT-PCR method using Tobamovirus primers (TobRT-up1 and TobRT-do2) and Potyvirus primers (MJ1 and MJ2) can detect double infection caused by ReMV with PVY in tobacco plants distributed in Central Java and Special Region of Yogyakarta. The multiplex RT-PCR product showed that tobacco samples with mosaic symptoms from Temanggung, Klaten, Bantul, and Kalasan were positive ReMV. Multiplex RT-PCR has successfully detected double infection of ReMV and PVY on tobacco samples from Klaten and Kalasan. ReMV Bantul, Kalasan, and Klaten were homolog to ReMV USA isolate and ReMV Temanggung was homolog to ReMV Japanese isolate. PVY Klaten was homolog to PVY Turkey isolate, and PVY Kalasan was homolog to PVY Iran.

Abstract

Phytopythium vexans (de Barry) Abad, de Cock, Bala, Robideau, Lodhi & Lévesque was successfully isolated from soil of potato fields in Ngablak, Magelang. This research aimed to obtain the knowledge of P. vexans potency as a pathogen in potatoes, and also morphologically and molecularly identify P. vexans compared to the Oomycetes, Phytophthora and Pythium. Morphological identification was conducted by observing macroscopic colony pattern that grew on PDA medium for five days and microscopic observation on its hyphae, sporangia, papillate, and chlamydospore. Molecular identification was conducted using multigene analysis, ITS and LSU. The in vitro pathogenicity test was obtained by inoculating P. vexans inoculum to healthy potato leaves and tubers. Results of morphological observation showed that P. vexans had a stellate pattern, aseptate hyphae, ovoid shaped sporangium and completed with semipapillate. Chlamydospores were also found and often used for survival. This research revealed that the morphology characters of P. vexans were combination between the characteristics of Pythium and Phytophthora. Whereas, based on the molecular analysis using ITS and LSU, Phytopythium spp. was more closely related to Phytophthora spp. rather than Pythium spp. The pathogenicity test of P. vexans showed that it could infect the flesh of potato tubers by showing a brown lesions symptom

Abstract

In Indonesia, rice is used as the first strategic and priority food commodity in agricultural development. However, in practice, efforts to increase it still experience various obstacles, one of which is caused by the attack of pathogen Rhizoctonia solani. This study aimed to determine the characters of R. solani and observe its pathogenicity on some local rice varieties in the Special Region of Yogyakarta. Four isolates of R. solani were used, namely RS MS2, RS MKP2, RS UMB, and RS PN, as well as six varieties of local rice varieties, which were Menthik Susu, Cempo Merah, Cempo Hitam, Segreng, Menoreh, and Hitam Makaryo, and national rice varieties IR 64 and Ciherang. Morphological characterization was carried out based on the cultural characteristics of the colony, hyphae, and sclerotia. A pathogenicity test was carried out using the Detached Leaf Inoculation method. The result showed that R. solani characters vary from whitish-brown, yellowish-brown, and light brown colonies; moderate and fast growth rates; abundant-aerial, moderate-aerial, and slight-aerial growth patterns; 90° hyphae branching, narrowing of hyphae at the branching point, and presence of sclerotia. The pathogenicity test gave the results of all isolates having varying pathogenicity levels on each rice variety. Menthik Susu, Cempo Hitam, and Hitam Makaryo were resistant to R. solani. Cempo Merah and Segreng were considered as moderately resistant varieties, whereas Menoreh was categorized as moderately susceptible. Ciherang and IR64 were susceptible varieties to R. solani.

Abstract

Rice blast disease has become endemic in Purwoasri Village, Gumukmas District, Jember Regency since 2018; this was due to the use of the Ciherang variety planted continuously. The study aimed to use the indigenous microorganisms IM) suspension made by farmers from Pos Pelayanan Agens Hayati (PPAH, Biological Agent Service Post) in Ambulu District as the control agent for blast pathogens and increased rice production. The roots of rice seeds were dipped in IM suspension at a concentration of 50 mL/L for 2 hours to penetrate to roots. Seedlings with IM were planted in a block of 250 m2, and control was also planted in the same block size. In the IM-treated block, the incidence and severity of blast disease decreased compared to the control. The root treated by IM dipping was also increased the plant growth, including root architecture, root length, root volume, and the number of tillers/plant; furthermore, it improved rice production. It was found that IM suspension contained pseudomonad fluorescent and Bacillus sp. that belong to Plant Growth Promoting Rhizobacteria (PGPR) group.

Abstract

Brown planthopper (BPH) is a major pest in rice plants and has become a global pest. This pest causes hopperburn in rice plants. This research aimed to know the effect of vermicompost from different feeding materials on rice plant damage by brown planthopper attack. This research was carried out between November 2019–March 2020 at the Sistandu integrated farming system, Serang City, Banten. The experiment method used in this research was a factorial Randomized Block Design (RBD) and consisted of two factors with three replications. The first factor was vermicompost (P) 5 levels, while the second factor was rice varieties (V) with two groups resulting in ten treatments. Data were analyzed with ANOVA, then followed by a 5% DMRT. The results showed that the application of vermicompost with different feeding materials had non-significant effects on growth of rice plants in the vegetative phase and fecundity of the BPH. However, it significantly affected the intensity of rice plant damage in the generative phase, the offspring population of BPH, and the BPH feeding rate. While the use of two varieties of rice did not have distinct effects on all parameters. There was no interaction effect between the two factors tested, both vermicompost feeding material treatment and rice plant variety, to all the parameters that have been studied.
