Abstract

This study aimed to 1) Analyze several Pseudomonas fluorescens group’s ability to induce resistance of chili plants to yellow curly virus infection. 2) Analyzing the ability of several Pseudomonas fluorescens groups to stimulate the growth of chili plants. The experimental design used a completely randomized design (CRD) with four levels of treatment, namely : control (untreated chili plants), SKM1 (chili plants treated with Pseudomonas fluorescens group SKM1), MP1 (chili plants treated with Pseudomonas fluorescein group MP1), and MM2 (chili plants treated with Pseudomonas fluorescens group MM2). Bacterial treatment was carried out by immersing chili seeds into a solution of the Pseudomonas fluorescens group with a concentration of 109 CFU/ml. Virus transmission in chili plants was carried out naturally in areas of high yellow curly disease epidemics. The results indicated that chili plants treated with Pseudomonas fluorescens groups SKM1, MM2, and MP1 had increased resistance to yellow curly virus infection and decreased percentage of attacks from yellow curly virus disease. Chili plants treated with Pseudomonas fluorescens group MM2 showed higher plant’s height and more branches than those treated with SKM1, MP1, and control. Chili plants treated with Pseudomonas fluorescens groups MM2 and MP1 have faster flowering time than those treated with SKM1 and control.

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.
