Abstract

Pepper yellow leaf curl Indonesia virus (PepYLCIV) is an important pathogen on chili cultivation and is transmitted through the seed. Serological tests are sensitive, accurate, efficient and it has been widely used for the detection of seed-transmitted plant viruses. This study aimed to produce PepYLCIV recombinant protein as a material to produce recombinant antibodies PepYLCIV. DNA was extracted from infected chili leaves collected from Congkrang, Muntilan, Central Java verified using primer PepYLCIV-BamHI and PepYLCIV-EcoRI and produced an amplicon at 840 bp. The amplified fragments were cloned into the pET32a then transformed to Escherichia coli BL21. The percentage of nucleotide sequence identity and sequence of amino acid, PepYLCIV CK-6 isolates had the highest similarity of nucleotide and amino acid sequences to of chili isolates from Bandung. The expressed recombinant protein was obtained with IPTG concentration 0,5 mM and harvested at 6 hours after IPTG induction. SDS PAGE analysis of the recombinant plasmid Begomovirus CK-6 showed that the coat protein size was about 29 kDa. Immunization was carried out on rabbits by injecting 150 µg of recombinant protein 4 times with an interval of 1 week to produce crude antiserum and pure antiserum capable of detecting PepYLCIV in chili and Ageratum conyzoides using I-ELISA and DIBA tests.

Abstract

The demand for horticultural products that are cultivated organically has increased. However, the susceptibility of plants to pests and diseases becomes an obstacle in organic crop cultivation. The use of biopesticides can be a solution to overcome these problems with the added benefit due to its environmental friendly and sustainable aspect. The purpose of this study was to determine the effect of biopesticides and combined fertilization in promoting plant health and enhancing tomato growth on the peat soil. This study used a randomized complete block design with two factors and three replications. The first factors were four combined fertilizations (K), namely: K1: 100% organic fertilizer+local microorganisms; K2: 75% inorganic fertilizer+Petrobio, K3: 75% inorganic fertilizer+M-Dec, and K4: 100% inorganic fertilizer. The second factors were three types of pesticides (S), namely: S1: homemade biopesticides, S2: industrial biopesticides containing active ingredient Eugenol 188,4 g L-1, and S3: chemical pesticides containing active ingredient fipronil 50 g L-1. The observed data were analyzed statistically using Analysis of Variance (ANOVA) and further tests were carried out using Duncan’s Multiple Range Test (DMRT) at the 5% level. The results showed that the tuba roots and betel leaves used in biopesticides had different effects on controlling fruit flies and leafminer caterpillars, as well as anthracnose disease. The application of chemical pesticides influenced the lowest infestation of fruit flies and leafminer caterpillars, while homemade and industrial biopesticides, as well as chemical pesticides had the same effect in reducing the intensity of anthracnose. In conclusion, a combination of 100% inorganic fertilizer+industrial biopesticides and 75% inorganic fertilizer+Petrobio gave greater tomato yields. Biopesticides could sustain organic crop cultivation in peatlands considering the ingredients availability, affordable, and easy application.

Abstract

The efficacy of plant-derived insecticides was compared with a synthetic insecticide, Lambda-cyhalothrin over two cropping seasons (2015 and 2016) against Leucinodes orbonalis, the eggplant fruit and shoot borer (EFSB) infesting eggplant, Solanum gilo. The plant materials included oil palm (Elaeis guineensis) bunch ash, soursop (Annona muricata) seeds, and goat weed (Ageratum conyzoides) leaves. These plant materials were formulated into aqueous extracts of 150 g/L (w/v), while Lambda-cyhalothrin was applied at the rate of 5 mL/L (v/v). The experimental design was a Randomized Complete Block Design (RCBD). There were 5 treatments with 3 replications applied on 2 cultivars of eggplants (Afufa Ukwu and Ngwa Large). Percentage fruit damage varied significantly (P< 0.05) with various treatments. The lowest mean percentage fruit damage was observed in the plot treated with Lambda-cyhalothrin (20.38%), followed by goat weed (29.03%), soursop (40.69%), palm bunch ash (43.30%) and the control (67.08%) for 2015 and 2016. Other parameters measured followed the same trend. Mean yield was significantly affected by the treatments. The highest mean yield was obtained from the plots treated with Lambda-cyhalothrin (12,346.6 g), followed by plots treated with goat weed (11,295.0 g), soursop (9877.2 g), palm bunch ash (8729.4 g) and control was the least (6583.0 g). Among the plant extracts, A. conyzoides that recorded low mean percentage damage had very high yield. Therefore, it can be used as insecticides in the control of EFSB.

Abstract

Excessive use of pesticides confers several ecological and environmental consequences. In this research, we evaluated arthropod occurrence on shallot crops in Palu Valley, Central Sulawesi as an impact of pesticide application in different frequencies. Almost all farmers used synthetic pesticides for controlling pests and diseases where 46.7%, 43.3%, 10.0% of them applied in high, moderate, and low frequency, respectively. By comparing to the last application, the first reduced arthropod diversity index, evenness index, and abundance by 13.8%, 6.7%, and 70.6%, while the second by 7.3%, 2.3%, and 33.5%, respectively. Analysis of the dynamic abundance of pests and natural enemies in seven weeks observation indicated that the pests abundance at low and moderate levels was no different. Whereas predator abundance at low frequency was significantly different with moderate and high rate and between the last two not distinct and the presence of parasitoids was not observed at all, it means the natural enemies were susceptible to pesticides. These data showed the negative impact of pesticides application to arthropods including pests resistance and natural enemies lost; therefore it is necessary to minimize the use of pesticides and integrated pests.

Abstract

The attack of Etiella zinckenella Treitschke on soybean varieties. Soybean is an important food and source of vegetable protein. One of the problems in soybean cultivation in Indonesia is the presence of pests. Integrated pest control (IPM) techniques are increasing along with the awareness of the importance of environmentally friendly sustainable agriculture. One component of IPM is the use of pest-resistant varieties. This study aimed to examine the effect of the soybean varieties against E. zinckenella Treitschke. This research was conducted with a factorial Randomized Completely Block Design (RCBD). The first factor was the type of organic fertilizer with a dose of 10 tons/ha: (P0= control, P1= Bokashi, P2= Vermikompos, P3=cow manure). The second factor is soybean varieties, which were: V1= Dena 2, V2= Dering 1, V3= Deja 2, V4= Deja 1, V5= Devon 1, V6= Devon 2, V7= Derap 1, V8= Derap 2, V9= Devatra 1, V10 = Devatra 2, V11= Detam 1, V12= Detam 2. The results showed that the interaction between varieties and organic fertilizer significantly affected the percentage of pod borer attack. The interaction between P1 x V8 varieties and between P2 x V6 varieties resulted in the highest percentage of pod borer attack and it was significantly different from other interactions, but not significantly different from P3 x V9, P3 x V5, P2 x V11, P1 x V6, P0 x V11, and P0 x V6.

Abstract

Banana bunchy top virus (BBTV) mostly infects Musa spp. which causes banana bunchy top disease (BBTD), the most devastating viral disease in banana cultivation all over the world. During field survey in Sekar Bumi Tropical Farm located in Kerta Village, 15 heliconia plant samples showed green streak on lamina leaves that similar to common BBTD symptoms were collected. Further research was then conducted to identify molecular characteristic of BBTD in heliconia showing green streak. Molecular identification was conducted using polymerase chain reaction (PCR). Specific primers to amplified DNA target were used in this study: mRep/F (5’-GCGTGAAACGCACAAAAGGCC-3’) and mRep/R (5’-GCATACGTTGTCAAACCTTCTCCTC-3’). The expected 240 bp fragment target of partial master replication (mRep) gene was successfully amplified from ten out of 15 samples. Sequence analysis confirmed that the symptomatic heliconia samples were infected with BBTV and falls into the same clade with BBTV from the Asian Group.

Abstract

Sugarcane disease disturbance is one of the limiting factors in achieving high productivity. Xylaria sp. has become endemic to sugarcane plantations in Lampung and South Sumatra. The intensity of disease attacks in Indonesia by 25% and 26% can reduce sugar production 12.3 and 15.4%, respectively. Losses due to disease attacks are greater in ratoons because plant cane sugarcane which is attacked by this disease, in ratoon stage, there will be a decrease in the number of shoots. The aim of this study was to obtain isolates of Trichoderma spp. which have antagonistic abilities and have chitinase enzymes so that they are effectively used as biological agents against Xylaria sp. The research method of antagonist test used dual culture test and qualitative test of chitin substrate was used to assess the chitinolytic index of four isolates of Trichoderma spp. The parameters were the inhibition of Trichoderma spp. isolates and the chitinolytic index of the four isolates moreover the value of the chitinase enzyme activity of the selected isolates. Mechanism of antagonist T10 are competition, antibiosis and mycoparasitism. The results showed that the Indonesian Sugar Research Institute (ISRI) T10 isolate could be used as a biological agent against Xylaria sp. The isolate had an inhibitory ability 73.33% with a chitinolytic index value 1.15 and the activity value of the chitinase enzyme crude extraction at a dilution 10-1 was 10.99 units/mL.

Abstract

Squash mosaic virus (SqMV) has been reported to infect cucumber plants in Java and cause a decrease in fruit quality and quantity. Until now, there is no information regarding Sqmv infection in Cucurbitaceae in Bali. In a preliminary research conducted during 2020, we found mosaic symptoms in Gianyar, Bali. SqMV was inferred to be the possible cause of the virus-disease-like symptoms. The study aimed to determine the precence of SqMV in Gianyar, Bali and to obtain information related to its molecular character. This research method includes surveys, field observations, virus identification by RT-PCR, and DNA analysis. Severe disease incidence caused by SqMV was observed on cucumber cultivation in Gianyar that was in the range of 5.81–66.87%. PCR using specific primer for coat protein (CP) gene of SqMV was successfully amplified the DNA fragments of ± 582 bp on samples from Payangan, Tegallalang, Ubud, Sukawati, Blahbatuh, and Gianyar districts, except for samples from Tampaksiring. This indicates that the presence of SqMV is widespread in Java and Gianyar.The SqMV isolate from Bali had the highest nucleotide homology at 91.9–93.4% and amino acids 94.0–94.5 and was closely related to the Brazil isolate (KT923125) and had lower isolate homology than other countries (China, Trinidad, Spain, Japan, Arizona, Cekoslowakia, and Australia). It proved that those mosaic symptoms on cucumber is associated with SqMV infection. SqMV is classified as a quarantine organism of category A2, so it is necessary to prevent its spread to other areas.

Abstract

Plant growth promoting rhizobacteria (PGPR) viz. Pseudomonas fluorescens, Bacillus megaterium, B. subtilis, and B. cereus and their metabolic products may play a pivotal role in controlling root rot and wilt diseases in faba bean plants caused by Rhizoctonia solani, Fusarium solani, F. oxysporum, and Macrophomina phaseolina and promote plant growth under greenhouse and field conditions. Cell cultures, extracellular metabolites, volatile metabolites of all tested PGPR strains were suppressed the linear growth of all tested pathogenic fungi in vitro. P. fluorescens followed by B. megaterium were more active than B. subtilis and B. cereus in reduction of the tested fungi radial growth. All PGPR strains were able to produce IAA, HCN, siderophore, Ammonia in media growth. P. fluorescens produced the highest levels of cyanide hydrogen and ammonia followed by B. subtilis, while the higher level of IAA was produced by B. subtilis followed by P. fluorescens. Also, B. megaterium was the most PGPR strain produced siderophore followed by P. fluorescens. All the tested PGPR strains successfully solubilized inorganic phosphate on Pikovskya’s agar medium. Also, all plant growth promoting rhizobacteria strains (PGPR) were able to produce mycolytic enzymes viz. cellulase, chitinase ?-1,3-glucanase, amylase and protease except B. cereus and B. megaterium not able to produce protease and amylase. B. megaterium recorded the highest activities of chitinase, ?-1,3-glucanase, while, B. cereus produced the lowest levels of all tested enzymes.
