Abstract

One of the important diseases that attacks red rice plants is narrow brown spot (Cercospora oryzae). Biological control is an alternative that needs to continue to be explored to become an environmentally friendly control solution. The aim of this research was to determine the effect of application time and administration of Trichoberas, endophytic bacteria, jengkol bark in suppressing narrow brown spot disease in red rice in wetlands. Each of these studies used a Completely Randomized Design (CRD) method consisting of 6 treatments which were repeated 4 times so that there were 24 experimental plant units. The results of field research showed that Trichoberas + endophytic bacteria + jengkol peel solution applied three times to red rice plants aged 60, 70 and 80 days could reduce the percentage of infected leaves by 90.63% with a control of 95.95% and an intensity of 48 .01% with a control comparison of 51.69%. The application treatment of Trichoberas + endophytic bacteria + jengkol peel solution on red rice plants aged 80 days (T3) and 60, 70 and 80 days (T5) was able to increase the number of grains, namely 317.25 grains and 325 grains compared to the control 281.75 grains. . The application of Trichoberas + endophytic bacteria + jengkol peel solution to red rice plants aged 60 and 70 days (T4) and aged 60, 70 and 80 days (T5) was able to increase the weight of 1000 grains, namely 18.75 grams and 19.5 grams compared to control 13.25 grams. All treatments were unable to increase plant height growth.

Abstract

Red rice (Oryza nivara L.) is a type of rice whose consumption level is increasing every year. However, obstacles in cultivating red rice often occur due to disease attacks, one of which is fusarium wilt. The aim of this research was to determine the effectiveness of varying the application time of trichocompost combined with betel leaf solution in suppressing the incidence of fusarium wilt disease in red rice plants. The research method used a Completely Randomized Design (CRD) which was carried out in the Phytopathology laboratory and greenhouse of the Department of Plant Pests and Diseases, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. The results of the study showed that the treatment given trichocompost and betel leaf solution with application times a week before planting, during planting, and a week after planting was able to reduce the incidence of disease by up to 35.00% with a control effectiveness percentage of 62.16% compared to the control treatment which had the incidence disease amounted to 92.50%. Application of trichocompost and betel leaf solution with varying times on red rice was able to extend the incubation period of the pathogen up to 20.25 days compared to the control, namely 12.53 days. Plants that were given the application of trichocompost and betel leaf solution were also able to increase plant height by up to 102.83 cm with a total of 8.78 tillers compared to the control without treatment which had a plant height of 76.30 cm with a total of 4.30 tillers.

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.

Abstract

Biointensive Control of Begomovirus in Big Red Chili Plants (Capsicum annuum L) Based on Barrier Plants in Southeast Sulawesi. Begomovirus is a disease-causing agent from the plant virus group. This disease is one of the inhibiting factors for chili cultivation in various countries and regions in Indonesia. If chili plants are infected when they are still young, it can cause yield loss and crop failure. The spread of Begomovirus in the field is determined by whitefly insects. Controlling the population of vector insects is important to reduce infected plants. Barriers around chili plants can be used as vector barriers in the field. The purpose of this study was to evaluate the control of Begomovirus on large red chili peppers using the Biointensive barrier plant model. The method used was Randomized Block Design (RAK), analysis of variance and further BNT test with a confidence level of 95%. Observation variables included: symptoms, incidence and severity of Begomovirus disease, whitefly population and growth and production of chili. The results showed that the biotic barrier planting pattern of kenikir flowers affected the decrease in the whitefly insect population, incidence and severity (PepYLCIV) and increased red chili production. The lowest whitefly population was 0.45 individuals/plant compared to the control of 1.08 individuals/plant, the lowest incidence and severity (PepYLCIV) were 45% and 1.33% with the highest chili production (1.14 kg-plot) compared to the control (0.31 kg-plot).

Abstract

Botanical pesticides are pesticides derived from natural plant products that contain bioactive compounds such as secondary compounds. This compound can function as an inhibitor of development, reduces fertility, inhibits appetite (anti-feedant), repellent, attractant, has a direct effect as a poison and prevent and reduce put down the egg. Botanical insecticides are insecticides produced from plant extracts, which are obtained from various parts of plants such as flowers, fruit, seeds, leaves, stems and roots, which contain secondary metabolite compounds. Secondary metabolite compounds produced by plants include essential oils, alkaloids, phenols, flavonoids, tannins, triterpenoids, steroids and saponins. Several lying plants that produce secondary metabolite compounds are good alternatives as a source of raw materials for vegetable insecticides because they are easy to obtain and do not require fertile soil to grow, including: Tinospora crispa (L.) Miers., Azadirachta indica (A.) Juss., Swietenia mahagoni and Annona squamosa.

Abstract

Rice storage for long periods often faces pest problems, one of which is Sitophilus oryzae L., which causes weight loss, contamination by insects, and a decrease in the nutritional quality of rice. To overcome this, the use of vegetable pesticides is an environmentally friendly alternative. Botanical pesticides are natural compounds that come from plants and can act as repellents, attractants, antifertility and have toxic effects on pests. This study aims to determine the effectiveness of stems and chopped citronella (Cymbopogon nardus) in controlling S. oryzae during rice storage. The design used was a Completely Randomized Design (CRD) with eight treatments and three replications. The results showed that the Z5 treatment gave the highest mortality of 14.00%, while the control (KO) only had 3.33%. The highest percentage of damage occurred in KO (59.33%) and the lowest in Z2 (13.00%). The highest population of S. oryzae was found in KO (87.00) and the lowest in Z5 (28.00), indicating the effectiveness of this treatment. It can be concluded that the provision of citronella stems and chopped citronella can significantly reduce the population, mortality and damage to rice caused by Sitophilus oryzae during 40 days of storage.

Abstract

Leaf fall disease is one of the main problems in rubber plant cultivation (Brazilian rubber tree) which can significantly reduce latex productivity. This study aims to observe the intensity of leaf fall disease attacks on rubber plants treated with organic fertilizer plus Trichoderma, Plant Growth Promoting Rhizobacteria (PGPR), and eco-enzymes. Observations were conducted three times in the rubber plantation owned by PT. Bridgestone Kalimantan Plantation (BSKP), using a visual assessment method for disease symptoms and calculating the percentage of infected leaves. The data obtained were analyzed descriptively and quantitatively to determine disease progression trends. The results showed that the application of organic fertilizer plus PGPR was able to suppress disease attacks by 74.50%. followed by other treatments: application of organic fertilizer plus Trichoderma, control plants without application, and organic fertilizer plus Trichoderma supplemented with eco-enzyme, with percentages of attack suppression of 68.97%, 68.83%, and 66.83%, respectively. Air humidity and daily rainfall factors showed a positive correlation with increasing attack intensity. These findings demonstrate the importance of environmentally friendly disease control strategies. This research is expected to form the basis for more effective and sustainable management of leaf fall disease.

Abstract

Bananas are a major horticultural commodity that makes a significant economic contribution in Indonesia. However, the productivity of this crop has declined drastically due to a blood disease infection caused by the banana. Blood Disease Bacterium (BDB). One type of pathogenic bacteria in the BDB group isRalstonia syzygii subsp. indonesian, which is known to be highly aggressive and easily spread. Efforts to control this disease generally rely on the use of synthetic bactericides, which risk environmental pollution and the development of pathogen resistance. Therefore, safer and more sustainable control alternatives are needed, such as the use of botanical pesticides from local plants. This study aims to evaluate the antibacterial activity of kratom leaf extract (Mitragyna speciosaKorth) on growthR. syzygii subsp. indonesianKratom leaf extract was obtained through a maceration method using 96% ethanol as a solvent, and antibacterial testing was conducted using agar diffusion techniques using paper discs. The extract concentrations tested included 5%, 10%, 15%, 20%, and 25%. The results showed that administration of kratom leaf extract (Mitragyna speciosa) at various concentrations is able to inhibit bacterial growthRalstonia syzygii subsp. indonesianin vitro. The average diameters of the inhibition zones observed for concentrations of 5%, 10%, 15%, 20%, and 25% were 4.15 mm; 6.71 mm; 7.75 mm; 8.39 mm; and 10.00 mm, respectively, while the control (0%) showed no antibacterial activity (0 mm). Further DMRT test results at the 5% level showed significant differences between treatments. This indicates that kratom leaf extract has potential as an antibacterial agent with the highest effectiveness obtained at a concentration of 25%.
