The potency of calabur tree (Muntingia calabura) leaf extract to control anthracnose of papaya fruit. The papaya anthracnose caused by Colletotrichum gloeosporioides is one of the factors causing a decrease in papaya production. The research aimed to determine the abilty of calabur tree leaf extract in inhibiting growth, sporulation, and viability of C. gloeosporioides as well as incubation period and disease severity on the fruit of papaya. The experiment was arranged in a nested design, the concentrations (0, 10, 20, 30, 40, 50, and 60%) were nested within the calabur tree leaf extract methods (boiling and fractionation). The results showed that boiled calabur leaves extract was more effective than fractionated calabur leaves extract to inhibit growth of C. gloeosporioides. Boiled calabur leaves extract and fractionated leaves extract at various concentration showed capability to inhibit the growth, sporulation and viability of C. gloeosporioides. Boiled calabur leaves extract at different concentration levels were able to suppress disease development of papaya anthracnose disease on papaya fruit. The higher concentration of calabur leaves extract, are more effective to inhibit C. gloeosporioides.

Infestation of major pests and diseases on various cassava clones in Lampung-Indonesia. Lampung Province is one ofcassava producers in Indonesia which contributes more than 30% to the total national cassava production. However, theinfestation of pests and diseases can limit cassava production in the field. The objective of this research was to observe theinfestation level of major plant pests and diseases of cassava in Lampung. A survey was conducted in August 2016 in severallocations of cassava fields owned by farmers and experimental plots in the area of Faculty of Agriculture, University ofLampung. The results showed that cassava mealybug (Phenacoccus manihoti), papaya mealybug (Paracoccus marginatus)and red mite (Tetranychus urticae) infested at cassava clones in Lampung. The infestation of red mite tended to be higher thanthat of mealybugs. The cassava brown leaf spot disease that infested in mild to moderate severity was found on all cassavaclones, while viral disease with prevalence of 78% was only found on Duwet 1 clone in experimental plot.

The preventive control of white root rot disease in small holder plantation using botanical, biological, and chemical agents. A field and laboratory experiment were conducted from June 2008 to December 2009 in Panumangan, Tulang Bawang - Lampung. The field experiment was intended to evaluate the effect of botanical plants (Alpinia galanga, Sansiviera auranthii, and Marantha arundinacea), biological agents (organic matter and Trichoderma spp.), and chemical agents (lime and natural sulphur) on the incidence of white root rot disease and population of some soil microbes. The laboratory experiment was conducted to observe the mechanism of botanical agents in controlling white root rot disease. In the field experiment, the treatments were applied in the experimental plot with cassava plant infection as the indicator. The variables examined were the incidence of white root rot and population of soil microbes. In the laboratory experiment, culture of R. microporus was grown in PDA containing root exudate of the antagonistic plant (botanical agent). The variable examined was colony diameter of R. microporus growing in the PDA plates. The results of the field experiment showed that planting of the botanical agents, and application of Trichoderma spp., as well as natural sulphur, decreased the incidence of white root rot disease. The effectiveness of M. arundinacea and Trichoderma spp. was comparable to natural sulphur. The laboratory experiment showed only root exudate of A. galanga and S. auranthii that were significantly inhibit the growth of R. microporus.

Diversity and abundance of soil-borne pathogenic fungi in various land-use systems in Sumberjaya, Lampung. This study was aimed to investigate the effects of land use systems on diversity and abundance of soil-borne pathogenic fungi. Soil samples were collected from Sumberjaya area, West-Lampung, during October 2004. A total of 88 soil samples were collected from seven land use systems: (1) undisturbed forest, (2) disturbed forest, (3) shrub, (4) polyculture coffee, (5) monoculture coffee, (6) food crop, and (7) horticulture crop. The soil samples were laboratory analyzed to isolate and enumerate viable fungal propagules using bioassay procedure by a modified most probable number technique. The results of the study showed that land-use systems had different impacts on diversity and abundance of soil-borne pathogenic fungi. The diversity declined in non-agricultural systems from undisturbed forest to disturbed forest, shrub, and polyculture coffee, and then increased in agricultural systems from polyculture coffee to monoculture coffee, and food crop. In horticulture crop, however, the diversity was lower than that of in food crop system. The abundance had a similar trend except for horticulture crop that showed the highest population. The occurrence of soil-borne pathogens was different across land use systems. Fusarium spp. dominated all land uses, except in shrub that was dominated by Curvularia spp. Botryodiplodia spp. occurred in undisturbed and disturbed forests, decreased in shrub and then disappeared in other land uses. The occurrence of Phytophthora spp. and Pythium spp. was limited in undisturbed and disturbed forest, then disappeared in shrub, in polyculture and monoculture coffee, but increased significantly in food crops. Rhizoctonia sp. only occurred in undisturbed forest.

ABSTRACTCharacteristic of Nematodes Community at PGS Golf Course Bandar Lampung. Golf course is a unique ecosystem where plant parasitic nematodes inhabit and become important pest because they reduce the quality of the grass. The pest problems on golf course can be indicated by its characteristics of nematode community. Survey on nematodes community at PGS Golf Course Bandar Lampung was conducted from March to December 2004. The objective was to study the characteristics of nematode community in the part of golf courses hole (green, collar, apron, and fairway). Soil samples were taken from five holes each of it consists of green, collar, apron, and fairway, respectiveley. Nematodes extraction was done in Laboratory of Arthropod Pest, Department of Plant Protection University of Lampung. The result showed that at least 50 nematodes genera of 28 families inhabit PGS. The number of plant parasitic nematode genera was higher than the free-living one. The characteristic of nematodes community on green and collar was different than on faiway. Nematode abundance and diversity on green and collar were higher than on fairway. Based on abundance of nematode feeding group, maturity index of free-living nematodes (MI) and that of plant parasitic nematodes (PPI), green and collar part seemed to be more favorable to plant parasitic nematodes than free-living nematodes. The contrary happened for fairway. Four most dominant genera of plant parasitic nematodes on PGS golf course were Helicotylenchus, Hoplolaimus, Criconemella, and Xiphinema.

Screening on Antagonistic Bacteria of Ralstonia sp., the Causal Agent of Banana Bacterial Wilt in Lampung. This study was conducted on May to October 2006. This study was aimed to screen and collect potential bacterial antagonists toward Ralstonia sp., the causal agent of banana bacterial wilt; to identify the collected potential antagonists, and to test the capability of the bacterial antagonist in vitro. A survey to collect soil samples was conducted in 5 districts in Lampung, namely Bandar Lampung, Lampung Selatan, Tanggamus, Lampung Utara, Lampung Tengah, and Lampung Timur. Identification and test of the antagonistic capability was done in the Plant Disease Laboratory, University of Lampung. Identification of the antagonist bacteria was done through several biochemical tests i.e. : gram reaction, hypersensitive reaction on tobacco, oxidative-fermentative, colony color on YDC medium, fluoresence, nitrate reduction, gelatin reduction and starch hydrolise. The results were then compared to the guidelines of bacterial identification. Twenty one soil samples were collected from those surveyed areas to isolate antagonist bacteria, and 104 isolates were found to be antagonistic to Ralstonia sp.. Based on the biochemical tests, it was showed that 59 isolates were in the group of fluorecent pseudomonad and 45 ones were still unidentified. Out of 104 isolates found, 41 isolates have the ability to inhibit the growth of Ralstonia sp.

Nematode Diversity in a Range of Land Use Types in Jambi Benchmark Indonesia. This study was conducted in Jambi Benchmark, Indonesia from May 2004 to March 2005. Out of 70 sampling points, 35 soil cores were taken from five land use types including forest less intensive, forest intensive, shrub, tree-based intensive, and crop-based less intensive. From each soil core, 300 ml of soil was extracted by flotation and centrifugation technique using sucrose solution. One hundred randomly picked nematodes from each sample were identified to genus level. The collected data were nematode abundance, number of genera, and trophic groups. The results showed that a total of 100 nematode genera within 31 families and 8 orders were found from soil samples of Jambi Benchmark. The abundance of total nematodes, bacterial feeding, and plant feeding nematodes were low in the intensive land use but high in less intensive land uses, i.e. shrub, intensive forest, and less intensive forest. There was no significant correlation between land use intensity and the diversity of nematode taxa. Nematode maturity indices were not sensitive enough to measure ecosystem disturbance caused by human intervention in Jambi Benchmark.

The corelations between White Rot (Rigidoporus lignosus L.) incidence and soil characters of rubber ecosystem in Penumangan Baru, Lampung. A study was conducted to evaluate the corelation between soil characters and white rot incidence. The study was done in Penumangan Lampung from June 2007 to July 2008. Seven sites were observed on the incidence of white rot of indicator plants (cassava). Physical, chemical, and biological soil characters were correlated and regressed with white rot incidence. The results showed that there were correlation between white rot incidence and soil characters such as pH KCl, number of fungal genus (fungal diversity), Ca+, total cation, CEC, and saturation base. Ion Ca+, total cation, saturation base correlated positively with white rot incidence, on the contrary, fungal diversity, cation exchange capacity, and pH KCl correlated negatively with white rot incidence. Thus, efforts to increase fungal diversity, cation exchange capacity, and pH (in acidic soil) could be used as basic strategies to develope intergrated control of white rot disease.
