Abstract

Information about genetic variation of Ganoderma spp. As a couse of rot disease on plantation crops is necessary for consideration in efforts to protect crops. Exploration of the use of biological agents, especially Trichoderma spp., for the control of Ganoderma on forestry crops is still limited to laboratory testing. Its effectiveness to control Trichoderma spp. To protect plants in the nursery sengon being carried out, as well as to deternime its role in improving plant growth.

Abstract

Ganoderma infection, red root-rot fungi or basal stem rot disease is becoming more prevalent and causing significant loss in sengon (Falcataria moluccana) in Indonesia. Trichoderma spp. is the alternative choice in the biological control of Ganoderma sp The objectives of the research were to study the potential of biological agents antagonism Trichoderma harzianum and Trichoderma pseudoconingii against Ganoderma that attacked Sengon with in vitro method. Antagonism test of Trichoderma spp with co-culture method modification to five Ganoderma isolates on PDA medium was conducted in Forest Pathology Laboratory, IPB, Bogor. The potential biological agents for protecting Ganoderma spp. on sengon were T. harzianum strain DT38 and T. pseudoconingii DT39. The research results showed that the Trichoderma spp. inhibit growth of five Ganoderma isolates that were attacked sengon tree from Lampung (Ganoderma L12, L6, L3) and Kalimantan Selatan (K2, dan K1) between 11,7 – 48,8%.Keywords: Biological Control, Falcataria moluccana, Ganoderma sp., Trichoderma harzianum, Trichoderma pseudokoningii,

Abstract

Maesopsis eminii (Engl.) is a fast-growing tree species which are now begin to be exploited. This research was aimed to identify types of pathogens, disease incidence and severity of leaf blight disease in Maesopsis eminii seedlings. Methods include field observations, isolation of symptomatic leaf blight and subsequent testing of Koch's postulates. Results of field observations indicating that the incidence of the disease is at 99.44%, while the severity of the disease by 8.85%. When isolation of symptomaticleaf blight was found 8 kinds of isolate that have different colors. The isolates were found in plants are then inoculated on Maesopsis eminii, and almost all isolates can causing the symptoms of leaf blight. The result of Koch's postulates inoculated leaf, found two types of isolates were identical to the initial isolation. Pathogenicity test results showing isolates with 1.1 code has the highest percentage value of disease incidence and severity than the other isolates. The identification results show the isolates with 1.1 code is a type of fungus characterized by having sectional hyphae and contained conidia, this fungus belongs to a class of Deuteromycetes.Key words: Fungus, Koch's postulates, leaf blight, Maesopsis eminii Engl., severity of disease

Abstract

Pathogen Botryodiplodia sp. is a fungus that causes dieback and stems rot diseases that attack forestry plants. The control currently being used in the field is using chemical pesticides, which are harmful to the surrounding environment and the plant itself, so there is a need for another alternative, namely using citronella and patchouli essential oils. Essential oils of citronella and patchouli have active compounds that act as antifungals to inhibit the growth of the pathogenic fungus Botryodiplodia sp. This study aimed to analyze the effect of citronella and patchouli essential oils on inhibiting the growth of the pathogen Botryodiplodia sp. in vitro. The results showed that the 10% patchouli treatment had the highest PDA and PDB media inhibition value. The lowest inhibition value was found in the 1% citronella treatment. The level of concentration, type of oil, and active ingredients contained in the oil affect the increase in effectiveness in controlling the pathogen Botryodiplodia sp. Keywords: antifungal, Botryodiplodia sp., citronella, in vitro, patchouli

Abstract

The productivity of coffee plants on the most cultivated land in Garahan Village decreased. This decline is thought to be caused by, among others, climate change, land degradation and the presence of pests and diseases in coffee plants. This training aims to introduce pests and diseases in coffee-based agroforestry to farmers and develop environmentally friendly biofertilizers. This activity begins with a pre-test, socialization and training and ends post-test. Based on the survey and direct observation, coffee plants found upas fungal diseases, root diseases, and stem borer pests. The agroforestry system applied is complex and straightforward agroforestry. In complex agroforestry, coffee plants are grown with various other crops, such as pepper, vanilla, leucaena, taro, banana, gamal, and mahogany. Simple agroforestry consists of coffee land planted with single-shade crops such as leucaena and gamal or a combination of Leucaena and pine. The training results showed an increased farmer's better understanding of coffee pests and diseases, the benefits of agroforestry, and the manufacture of biofertilizers. The biofertilizer developed is expected to increase the productivity of coffee plants.

Abstract

Sengon (Paraserianthes falcataria (L.) Nielsen) is a fast-growing tree species, and its wood is readily available because it has been widely cultivated in Indonesia. Efforts to propagate sengon plants are carried out through breeding activities in the nursery. The study aimed to identify the fungus that causes leaf disease on sengon plants and calculate the extent and intensity of attacks by the fungus that causes leaf disease on sengon in the Dramaga Bogor Permanent Nursery. This research consisted of pathogenicity test activities, including field observations, Koch's postulates, and the identification of fungal species. The study used a Completely Randomized Factorial Design. The disease symptoms found around 2 months of sengon leaves at the observation site were leaf fall, leaf spot, and leaf blight. The identified fungus that caused leaf fall was Rhizoctonia sp. The fungus that caused leaf spots was Colletotrichum sp., and the fungus that caused leaf blight was Fusarium sp. Fusarium sp. resulted in the highest percentage of attacks, with a disease incidence of 67% and a disease severity of 57%. Keywords: characteristics, identification, Koch`s postulates, morphology

Abstract

The rice productivity in Gondel Village, Kedungtuban District, Blora Regency, Central Java, has declined. Factors such as attacks by plant pests and diseases (OPT), climate change (DPI) impact, and decreasing soil quality are the leading causes of crop failure. This training aims to enhance the understanding and skills of Gondel Village farmers in making biofertilizers and introducing environmentally friendly pest and disease control methods. The activity involved 40 farmers from 8 farmer groups (Gemah Ripah, Margo Mulyo, Ngudi Makmur, Sido Dadi, Sido Makmur, Tambah Makmur, Tambah Rizki, and Sri Mulyo), with each group represented by five farmers. The training methods included analysis of soil chemicals, socialization, practical propagation of Trichoderma sp. on rice media, and biofertilizer production. Pre-test and post-tests were conducted to assess the improvement in farmers' knowledge. Trichoderma biofertilizer was formulated using carriers such as a) Manure and b) Compost, zeolite, and humic acid. The results of the soil chemical properties analysis showed that farmers' use of chemical fertilizers was very intensive, resulting in very high levels of phosphorus (P) and calcium (Ca) and high levels of potassium (K), magnesium (Mg), and cation exchange capacity (KTK). Evaluation results indicated that the training significantly improved the farmers' knowledge of biofertilizer production in theory and practice. However, some farmers still need further guidance on the propagation of the biological agent Trichoderma sp.
