Abstract

Eggplant (Solanum melongena L.) The demand for eggplant was increasing, but the availability of eggplant is low so it cannot be fulfilled. One of the causes of low eggplant production is due to the attack of wilt disease on eggplant plants caused by Fusarium oxysporum. Symptoms include wilted leaves, yellowing leaves and brown root and stem tissue. Control that is often done is to use pesticides (fungicides) which can cause environmental pollution. One control of Fusarium spp. wilt disease. with microbial antagonists. This research was conducted to determine the ability of isolates of rhizobacteria Pseudomonas fluorescens group (PF) and Bacillus spp. from bamboo, chili and ferns inhibited the growth of Fusarium spp. in vitro. Completely Randomized Design (CRD) with isolates of Pseudomonas fluorescens group and Bacillus spp. each 4 treatments, control. Testing the inhibitory power of isolates of Pseudomonas fluorescens group and Bacillus spp. carried out by the challenge method and in vitro. Observations were made on the percentage of inhibition of rhizosphere bacteria (DH) after incubation for 7 days. All isolates of Pseudomonas fluorescens group and isolates of Bacillus spp. Has different inhibitory power on the fungus Fusarium spp. The isolates of Pseudomonas fluorescens group derived from bamboo roots from the Palem area (KPBP) (81.95%) were isolates that had the highest percentage of inhibition and Bacillus spp. derived from chili roots from the Guntung Manggis area (BGTP1) (70%) was the isolate that had the highest percentage of inhibition.

Abstract

Incidence of geminivirus infection has been caused severe losses on various economically important crops. This losses may cause by single infection or mix infection of several strain of geminiviruses. In this experiment we used two strain of geminiviruses, geminivirus infecting chillipepper from Segunung, West Java and geminivirus infecting tomato from Lembang, West Java (GVToL), to study the effect of geminivirus mix infection on the symptom expression and the capability of each strain to multiply in the host cell. Coefficient of dissimilarity between this two strain of geminiviruses is 7.5. When the two strain of geminiviruses was inoculated together to tomato plants by insect vector; Bemisia tabaci, the symptoms on infected plants is slightly different but less severe than those on plants inoculated with each strain separately. Detection with polymerase chain reaction (PCR) followed by restriction enzyme digest of PCR product revealed that GVToL multiply better in the infected host cell.

Abstract

Chili is an important commodity for most people, because of its function in terms of improving taste and appetite. Chili was seriously developed with the support of government funds for chili farmers. The development of chili plants, has enough obstacles, especially wich caused by plant disturbing organisms whether it is pests or diseases. The important organism that disturbs chili is wilting caused by Ralstonia solanacearum. In South Kalimantan, this disease reportedly attacked chilies spread in the districts of Banjar, Banjarbaru, Barito Kuala, Tapin, Hulu Sungai Tengah and Balangan with a cumulative attack area of 15,7 ha on 2017 (South Kalimantan BPTPH Database). This disease is important because of the nature of the attack which can cause the plants to wilt suddenly all part of the plant. Plants wich attacked by bacterial wilt cannot be cured. The effort that can be done in prevention before pathogens infect the plants (Sastra, 2004). One way to overcome this problem is biological control using biological agents from the type of antagonistic bacteria Bacillus spp, Pseudomonas fluorescens, and type of antagonistic fungus Trichoderma spp. From three biological agents proven able to inhibit the development of R. solanacearum in vitro which produces a zone of inhibition as wide as 13,5 mm for Bacillus spp, 22,25 mm for Pseudomonas fluorescens and 8,42 mm for Trichoderma spp. and can increase plant height growth, chili weight, root weight, wet weight, and dry weight plants. Trichoderma spp as the best biological agents for increasing chili growth and yield.

Abstract

One of the causes of the declining productivity of rice is sheath blight disease caused by the mold Rhizoctonia solani Kuhn. Control of sheath blight disease that is often done by the farmers is by using chemical pesticides (fungicides), which caused environmental problems. One way to reduce the use of pesticides is to biological control by using antagonist bacteria. This study aimed at in vitro test of rhizobacteria in preventing the development of sheath blight disease in rice plants. This research was conducted in the Phytopathology laboratory of Plant Protection Department of Faculty Agriculture, University of Lambung Mangkurat Banjarbaru from March to May 2018. The experiment used a randomized block design with three groups consisting of eight types of rhizobacteria isolates: (r1) Pseudomonas aeruginosa (Barito Kuala), (r2) Bacillus megaterium (Hulu Sungai Tengah), (r3) Azotobacter sp. (Barito Kuala), (r4) Pseudomonas sp. (Hulu Sungai Selatan), (r5) Flavobacterium sp. (Tanah Laut), (r6) Bacillus bodius (Barito Kuala), (r7) Pseudomonas aeruginosa (Hulu Sungai Selatan), (r8) Necercia sp. (Tanah Laut). The results showed that all rhizobacteria have the ability to inhibit the development of R. solani with different percentages of inhibitions. Pseudomonas aeruginosa (Barito Kuala) was the most effective rhizobacteria in inhibiting the development of R. solani.

Abstract

Palm has a fibrous root system, consisting of a primary root, secondary, tertiary and quaternary. In general, palm root system is closer to ground level, however, in certain cases it may penetrate deeper. One of the root functions is to absorb water and nutrients from the soil. Palm roots dispersion can be determined by using the geoeletric resistivity method. Geoelectric resistivity data using Wenner configuration method is measured in three trajectory forming an equilateral triangle on palm plant row with a variation of 9 m (AB / 2) in accordance with palm plant spacing, with potential electrode spacing of 30 cm (MN / 2). Collection of geoelectric resistivity data is done by injecting electric current into the earth through two electrodes, the potential difference is then measured through two potential electrodes. Measurements were performed by varying the distance of the electrodes and potentials, gradually from the smallest distance to the largest. Measurement of palm root dispersion detection consists of 3 tracks (L1, L2, and L3). Measurements on June 24, 2014 carried out on track 1 (L1) between rows of palm plants, track 2 (L2) between the palm plant within the same row, and track 3 (L3) diagonally between the rows of plants (Figure 1). Measurement on July 8, 2014 were on track 1 (L1) is between rows of palm plants, track 2 (L2) and track 3 (L3) diagonally between the rows of plants.Geoelectric on diagonal trajectory where modified biopore infiltration pit is in place resulted in low resistivity values. This is related to soil water availability, where it affects the development of the root towards the biopore pits.
