Abstract

AbstractOne problem that causing leaf mustard yield loss is the infection of Turnip Mosaic Virus (TuMV). Thevirus causes mild mosaic leaf with vein clearing, blister, malformation and stunting. The use of Plant Growth Promoting Rhizobacteria (PGPR) such as Pseudomonas fluorescens and Bacillus subtilis is oneeffort that could be used to solve the problem. Through the mechanism of induced resistance, thesebacteria can elicit the defense signal in plant for the defence against pathogens. In this study the use of Pseudomonas fluorescens and Bacillus subtilis was performed to test their benefit on leaf mustard planthealth against TuMV infection. This study was conducted with a randomized block design (RBD) byusing 8 treatments and 4 replications. On the experiment of the effect of PGPR on the root length ofleaf mustard plants, the design used was a completely randomized design (CRD) with 4 treatments and4 replications. Leaf mustard plants inoculated with Pseudomonas fluorescens and Bacillus subtilis hadlonger roots than those without the inoculation of Pseudomonas fluorescens and Bacillus subtilis. Inaddition, Pseudomonas fluorescens and Bacillus subtilis was also able to reduce the incubation periodand disease intensity of TuMV on the leaf mustard plant. The activity of catalase enzyme and phenolcontent was elevated in the leaf of leaf mustard plant inoculated with PGPR. The results suggested thatcatalase and phenol production probably play a role in plant defense of leaf mustard against theinfection of TuMV.Key word : Mustard, Turnip Mosaic Virus (TuMV), PGPR

Abstract

AbstractInfection of Cucumber Mosaic Virus (CMV) could reduce the tomato production up to 50%depending on the age of the plant during infection and tomato varieties. Until now the controlefforts against CMV infection have been made, but no consistent effective method was available.Recently, new approach by increasing the plant health to defense against plant disease wasincreased. It can be stimulated by inoculation of microbes associated with roots or by application of plant extract such as Mirabilis jalapa. In this study, the effect of M. jalapa leaf extract in differentconcentration to develop control against CMV infection in tomato plants was conducted. The results showed that the application of M. jalapa leaf extract could inhibit the development of CMV diseasein tomato plants. The higher the concentration of M. jalapa leaf extract applied on tomato plant, thelower disease incidence as well as the longer incubation period of CMV disease in tomato plants.The applications of M. jalapa leaf extract elevated the activity of peroxidase and catalase enzymes.Thus, the inhibition of CMV disease development in tomato plant by application of M. jalapa leafextract may related to the induction of peroxidase and catalase activity in tomato plants.Keywords: M. jalapa, CMV, plant defense, leaf extract, peroxidase, catalase

Abstract

Sprout disease (damping off) is one of the important diseases that attack a variety of horticultural plants. Besides, sprouts disease can also attack seeds that have not germinated (preemergence damping-off). This study aimed to determine and compare the ability of B. subtilis and T. harzianum in controlling the pathogen Pythium spp. in cucumber plants. Phy01CK and Phy01IP isolates were use in the virulency test and inoculation methods of pathogens. The inhibition test between B. subtilis and T. harzianum against Pythium spp. was conducted in the in vitro test. This research was used a randomized block design with 13 treatments and three replications. The results of the antagonist's effect in vitro between T. harzianum and Pythium spp. showed the highest suppressing growth of Pythium spp. which is 70%. B. subtilis, B. subtilis + T. harzianum and fungicides each having a zone of inhibition of 23%, 32% and 46%. In the in vivo tests, the application of biological agents with 3 different times was not affecting the incidence of damping-off disease at 10 days after planting.

Abstract

Herbicides are a substance or chemical compound used to inhibit growth or kill plants. Herbicides are toxic to weeds or pests as well as cultivated plants. The impact of using the herbicide paraquat causes some microbes to become more resistant and has the potential to be used as a paraquat biodegradation agent. Indigenous yeast is one of the microbes that can be used as a biodegradation agent because it is resistant to the environment. For this reason, This research aimed to investigate the indigenous yeast isolated from the potato field in Sumberbrantas village, Batu City as a bioremediation agent for paraquat herbicide residues.The sampling was carried out in the potato field of Sumberbrantas, Batu City, which in routine maintenance uses a herbicide with active paraquat (1,1 dimethyl -4, 4-bipyridinium dichloride).The isolation results obtained 6 isolates of indigenous yeast which had the potential as biodegradation agents for paraquat. Treatment of yeast isolates MB 1, MB 3, MB 4, MB 6, MB 7, MB 8 at concentrations of 250, 500, 1,000 and 2,000 paraquat were able to survive with a growth percentage of 75-100%. At a concentration of 5,000 Isolated yeast decreased with a growth percentage of 50-75% and MB 1 isolate with 10,000 ppm concentration still survive with a growth percentage of 1-25%. The highest biodegradability ability of yeast was in MB 1. The identification of MB 1 isolates based on molecular characters have similarities in the basic structure of 98.89% with Geotrichum silvicola UFMG 354-228S isolates with accession number NG_0606221.1.

Abstract

Papaya (Carica papaya L.) is an annual plant belonging to the Caricaceae family. Papaya populations in Indonesia can be found in almost all regions. The extensive papaya cultivation areas in Indonesia often involve planting on wild land, which exposes papaya plants to various diseases. Crown rot disease is an example of a disease in papaya. Papaya plantations in Jajag, Gambiran, Banyuwangi Regency, are known to be affected by stem rot. To determine the appropriate disease control measures, it is necessary to identify the cause of the wet rot disease in papaya plant stems. The research was conducted through several stages, including sampling, media preparation, isolation of pathogenic bacteria, hypersensitivity tests, pathogenicity tests, potato soft rot tests, colony and cell morphological observation, Gram staining, oxidative/fermentative, yellow colony on YDC media, lecithinase, catalase, sensitivity to erythromycin, carbohydrate fermentation, and temperature treatment at 37°C and 40°C. The results showed that the plant pathogenic bacteria causing crown rot at the base of the stem in papaya plants were isolates B1 and B2, belonging to the group of Pantoea sp.; isolates B3, B6, and B7, belonging to the group of Erwinia sp.; and isolates B4 and B5, belonging to the group of Dickeya sp..
