Abstract

Eggplant (Solanum melongena L.) is a native plant known to tropical regions in Indonesia. As an indigenous vegetable, eggplant is almost always found in farmer's markets and traditional markets at relatively cheap prices. Even though eggplant is a vegetable that is popular with the public, it seems that the cultivation of eggplant plants is not as intensive as the cultivation of other favorite vegetable plants such as chilies, tomatoes, onions, and others. The main problem in vegetable cultivation currently being experienced by eggplant farmers in the Ironwood area is the attack of the yellow mosaic virus pathogen. The research used a Completely Randomized Design (CRD) consisting of 5 treatments and 4 replications so that there were 20 experimental units. The five treatments given were K- (eggplant control plants without treatment), K+ (eggplant control plants inoculated with yellow virus), P (eggplant plants treated with isolates of the Pseudomonas group flourescens from Palam and inoculated with eggplant yellow virus), B ( Eggplant plants applied with isolates of the Pseudomonas group flourescens from Landasan Ulin and inoculated with eggplant yellow virus), C (Eggplant plants applied with isolates of the Pseudomonas group flourescens from Landasan Ulin and inoculated with eggplant yellow virus). The results of research that have been carried out have concluded that administration of rhizobacteria isolates P, B, and C can induce eggplant plant resistance to eggplant yellow virus infection, but cannot trigger plant height growth.

Abstract

Oryza sativa L. is the main food crop in Indonesia. The need for rice continues to increase every year. Rice production in South Kalimantan in 2019 reached 790,449 tons of rice, then in 2020 it decreased to 677,105 tons of rice. One of the causes of the decline in rice productivity is the attack of the brown planthopper (Nilavarpata lugens Stall.). This research aims to determine the effectiveness of the herbal pesticide babadotan leaves on the mortality of brown planthopper pests on rice plants. This research was designed using a Completely Randomized Design (CRD). The factors tested were the administration of a herbal pesticide solution of babadotan leaves at doses of 3%, 6% and 9% with a control treatment that was not given pesnab and a chemical control as a comparison. This study had 5 treatments and 4 replications. The results of the study showed that administering 9% herbal pesticide solution from babadotan leaves was effective in controlling brown planthopper pests with a mortality value of 80%.

Abstract

Shallots are one of the important vegetable commodities that have been intensively cultivated by farmers for a long time, including in the non-substituted spices group which functions as food flavoring seasonings and ingredients for traditional medicine. In the production process, various constraint were found, one of which is the attack of pathogens that cause moler disease. This study aims to determine the effectiveness of Bintaro solution on the intensity of Moler disease attacks on shallot plants on peatlands. The study was conducted at the Phytopathology Laboratory, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru and in Tegal Arum Village, Landasan Ulin District, Banjarbaru City, South Kalimantan, from June to October 2022. The study used a completely randomized design consisting of 4 treatments and 5 replications. The treatment tested was the application of old b intaro fruit, young bintaro fruit, bintaro leaves plus 1 control treatment. The application of vegetable pesticides was carried out by pouring the solution onto the surface of each shallot plant as much as 5 ml per plant, which was carried out 7 times with an interval of 1 week. Parameters observed were the intensity of the attack of moler disease, fresh weight of the bulbs, the number of bulbs and the diameter of the shallot bulbs. The results showed that the incubation period for the pathogen causing moler disease was 14 days. The application of bintaro plant solution was unable to suppress the attack of moler disease on shallots on peatlands and was unable to increase the number of shallot bulbs, but the application of old bintaro fruit was able to increase tuber wet weight by 41kg/ha and tuber diameter by 2%.

Abstract

Chili is one of the cultivated plants, one of the main problems that often occurs due to anthracnose attacks caused by the fungus Colletotrichum spp. One biological control that can be used is Trichoderma spp., Trichoderma spp. can produce secondary metabolites containing antibiotic compounds, enzymes, toxins and hormones. The aim of this research was to determine the potential of secondary metabolites of Trichoderma spp. which comes from the rhizosphere of bamboo, chili and elephant grass plants which have the potential to inhibit the development of the fungus Colletotrichum spp. anthracnose disease in vitro. The research method used a completely randomized design with a single factor. Consisting of three (3) treatments and one (1) control, repeated five (5) times, totaling twenty (20) experiments. This research was carried out at the Phytopathology Laboratory, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. The research results show different inhibitory forces. Secondary metabolites from the roots of chili plants showed a higher inhibitory power, namely 45.65% compared to 16.82% from the roots of bamboo plants and 16.71% from the roots of elephant grass plants. However, secondary metabolites from the roots of bamboo plants and elephant grass plants have the same abilities. A 20% concentration can inhibit the growth of Colletotrichum spp. on day 3, while further observation of the ability of secondary metabolites of Trichoderma spp. suppress the development of Colletotrichum spp. decreasing.
