Screening of indigenous rhizobacteria from healthy soybean root to control bacterial pustule (Xanthomonas axonopodis pv. glycines) using in planta technique. Plant growth promoting rhizobacteria are a group of bacteria that actively colonize plant roots, increase plant growth and control plant pathogens. The aim of this study was to obtain rhizobacteri isolates which have the ability to control bacterial pustule and increase growth and yield of soybean. This method based on in planta selection of enhanced competitive soil root-colonizing bacteria from soil samples of healthy soybean root at endemic area of bacterial pustule in Darmasraya District and Sijunjung District, West Sumatera. We characterized only the best rhizobacteri isolates which have ability to control bacterial pustule and to increase growth and yield of soybean. This type of characterization has possibility to find new, easy and cheap biocontrol organisms. Ten Rhizobacteri isolates were introduced via seed treatment (108 cfu/ml) and soil drench to 3 week old soybean seedling. Xanthomonas axonopodis pv. glycines were inoculated to one month old of soybean seedling. The effect of rhizobacteria on disease incidence, disease severity, plant growth and yield of soybean were evaluated. We have found that two selected rhizobacteri isolates from soybean (P12Rz2.1 and P14Rz1.1) were the best isolates in promoting growth and the of the soybean plants with the effectiveness 20.62 % and 20.47 %.

Pathogenicity of Beauveria bassiana Bals. Vuill. (Deuteromycotina:Hyphomycetes) on various stages of eggs and nymphs of the green stink bug (Nezara viridula L.) . The green stink bug (Nezara viridula L.) is one of the important soybean pod-sucking bug besides brown stink bug (Riptortus linearis) and green stink bug (Piezodorus hybneri). Up to now, pest control mostlyrely on the chemical insecticides, The objectiveof this experiment was to study the pathogenicity of Beauveria bassianaon various stages of eggs and nymphs of the green stink bug. Experiment was conducted in the laboratory of Entomology, Indonesian Legumes and Tuber Crops Research Institute (ILETRI) Malang, from January to June 2011. The treatments consists of various eggs and nymphs stages of green stink bug. The results showed that B. bassiana was able to infect the eggs green stink bug both of the newly laid and the six days old eggs. As a results of this infection, 96% eggs did not hatched. The younger of eggs, the more susceptible to B. bassiana. The infected egg prolonged hatching periods to three days. B. bassianawas also toxic to all stages of the green stink bug, especially to the first and second instarswith mortality rate of 69-96%. The nymph of third, fourth, ad fifth instar and adult stage were more tolerant to the B. bassiana infection.

ABSTRACTAbundance and Species Diversity of Predatory Spiders for Insect Pests Inhabiting Ratoon Paddy in Tidal Lowland. Ratoon paddy productivity is lower than the main crop. Increasing productivity of the ratoon paddy is to protect the paddy from pests and diseases. This study aimed to analyze the abundance and species diversity of predatory spiders of rice pests on ratoon paddy in tidal lowland. Ratoon paddy field observed was from the main crop that has been harvested and cut 20 cm height. Paddy area observed was 2 ha field planted using Ciherang and Inpara varieties. Spiders inhabiting canopy were sampled using insect nets but soil dwelling spiders were trapped using pitfall traps. The result showed that spider species inhabiting canopy of ratoon paddy were Pardosa pseudoannulata, Lycosa chaperi, Araneus inustus, Cylosa insulana, Atypena adelinae, Erigone bifurca, Erigonidium graminicola, Oxyopes javanus, Argyrodes miniaceus, and Marpisa magister. Spider species found soil dwelling were 11 species, namely Pardosa pseudoannulata, Pardosa sumatrana, Pardosa mackenziei, Pardosa oakleyi, Hogna rizali, Araneus inustus, Cylosa insulana, T. vermiformis, Runcinia albostriata, Coleosoma octomaculatum, and Marpisa magister. Abundance, species number, species diversity for soil dwelling spiders were higher than those for canopy inhabiting spiders. However, the abundance, species number, species diversity for the soil dwelling spiders tended to be higher on the ratoon paddy 3, 4, and 5 week old than those on 1, 2, and 6 week old. From the result, we concluded that abundance, species number, species diversity of spiders found in the ratoon paddy were higher or tended similar to those on the main crop.

ABSTRACTGenetic variation of leafhopper, Nephotettix virescens Distant active transmitters from endemic and non endemic areas of rice tungro disease based on RAPD marker. Leafhopper, Nephotettix virescens Distant (Hemiptera: Cicadellidae) plays an important role as a vector of rice tungro virus. However, the characters of N. virescens as a vector from endemic and non-endemic areas of tungro disease in Indonesia have not been well characterized and also available information is limited. The objective of this research was to study the character of N. virescens active transmitter from endemic and non-endemic of areas tungro disease based on RAPD markers. The N. virescens were collected from endemic area of Klaten (Central Java), Sleman (Yogyakarta) and non endemic area of Purwodadi (Central Java) Ngawi (East Java), and Pacitan (East Java). The N. virescens active transmitters were identified by their ability to transmit the virus based on Standard Evaluation System for Rice Tungro Virus, issued by IRRI. The genetic variations of N. virescens active transmitters were determined by using RAPD-PCR marker. Result of the research showed that three primers, OPB01, OPB10 and OPC08 amplified successfully of DNA template of N. virescens through RAPD-PCR technique. Based on the dendrogram, there were initial facts of possible genetic differences between the populations of N. virescens from endemic and non endemic areas of rice tungro disease. The N. virescens from endemic area of Klaten and Sleman are similar genetically but different from the N. virescens non endemic of Purwodadi, Pacitan and Ngawi.

ABSTRACTPineapple fruit collapse: newly emerging disease of pineapple fruit in Lampung, Indonesia Recently, a new disease on pineapple fruit has occurred in Lampung. Symptoms of the disease are complex. Fruits rotted and exuded copious liquid from the inter- fruitlet tissues accompanied by gas bubbles. Open spaces were formed inside the rotten fruit. Dissection of diseased fruit showed many cavities within its sceletal fibres and bad odour was exerted from the rotten tissues. A bacterial entity was isolated from the diseased materials. In a pathogenicity test, the isolated bacteria caused the same symptom as mentioned. In the growing-on test the crown of the heavily infected fruit showed heart rot symptom. Those indicated that the disease was pineapple fruit collapse. Both symptoms were known related to the same causal agent, Erwinia chrysanthemi (pineapple strain Dickeya sp.). In our opinion, this is the first report of pineapple fruit collapse in Indonesia.

Foot rot of black pepper (Piper nigrum L.) caused by Phytophthora capsici Leionian is commonly considered as one of the most important problems in black pepper production. The objectives of this research was to determine the influence of organic matter and Trichoderma spp. on the severity of foot rot of black pepper. On the first experiment, five Trichoderma mycelial plugs were applied on planting medium consisting of soil, organic matter, and sand (2:2:1, v/v), then incubated for 7 days. Black pepper plants were transferred to the planting medium and after 14 days were inoculated on the stems. The variable observed was disease severity on the stem. On the second test, Trichoderma that was grown on broken rice (menir) as starter was applied into the planting medium which consists of soil and sand (2:1, v/v). Two weeks later, black pepper plants were inoculated on the leaves and stems. The variables observed were the diameter of necrotic on the leaves and disease severity on the stem. On the first experiment when 15 isolates of Trichoderma spp. were tested, five isolates (T. harzianum isolates 6, 8, 9, 10, and 15) significantly reduced disease severity. However, on the second test when four out of the five effective isolates were retested, none was found to significantly reduce disease severity on leaves or stems.

Background : Overactive bladder (OAB) is a group of urgent symptoms, with or without urgent incontinence. Research shows that some Lactobacillus spp. can be a sign of a women bladderâ€™s good health; and found a decrease number of Lactobacillus spp. in patients with OAB. This study aims to assess the correlation of Lactobacillus spp. colony with OAB using the OABSS score at Pauh Primary Health Center, Padang.Method : This research is an analytic study with a cross sectional comparative design. The research was conducted from December 2019 to February 2020 at Pauh Primary Health Center. All women aged 20-40 years who came to Pauh Primary Health Center during the study period were included in the study. Pregnant women, having pelvic abnormalities and a history of other urinary tract diseases or having a history of hypertension and diabetes mellitus were excluded in the study. Numerical data are presented in the form of central tendency. Bivariate analysis was performed using the t-independent test if the data distribution was normal and the Kolmogorov-Smirnov test if the distribution of the data was not normally distributed.Result: There were 42 samples consisting of 21 OAB respondents and 21 normal respondents. The age of the respondents in the OAB group was 28 Â± 6.8 years, while the normal group was 32 Â± 7.3 years (p> 0.05). The number of Lactobacillus spp colonies in the normal group was higher than the OAB group, namely 16,389,670 Â± 74,380,427.9 CU / ml compared to 15,229,634 Â± 67,553,932.9 CU / ml (p> 0.05).Conclusion: There was no correlation between the number of Lactobacillus Spp colonies and the incidence of Overactive Bladder. It is necessary to do further research regarding other risk factors associated with the incidence of OAB and the causes of the decrease number of Lactobacillus spp colonies in OAB patients and the presence of other microorganisms, especially pathogenic microorganisms.Â Keywords: overactive bladder, Lactobacillus, OABSS score
