Abstract

Soybean Glycine max L. Merrill has a strategic position in food security. Soybean varieties are various, such as edamame or commonly called vegetable soybean. The important edamame pest is L. indicata. This pest has a natural enemy in the form of parasitoids that spread at several altitudes. This study aimed to investigate the L. indicata pest population and their parasitoid  in edamame soybean plantations at three different altitudes. In this study conducted at three altitudes namely Purwosari (12 masl), Sebanen (814 masl), and Karangbireuh (1295 masl). At each location consist of one plot (1 Ha) and were  made into 4 sub-plots exchanging 10 x10m. Also, the yellow pan trap was installed at  8–57 Day After Planting to collect L. indicata and parasitoid. The results showed that L. indicata was higher in Purwoasri than in other locations. This is due to environmental factors namely temperature. The parasitoid of L. indicata was found in all locations, namely Braconidae family (parasitoid of larvae). While the the paarasitoid were collected in yellow pan trap in all locations i.e. Pteromalidae, Diapriidae, Eulophidae, Mymaridae and Entomacis sp.

Abstract

Chili pepper (Capsicum frutescens L.) is a horticultural commodity that has high economic value and has the potential as an export commodity. One of the factors causing the decrease in productivity of chilli pepper is anthracnose caused by C. gloeosporioides. Consequently, plant-based fungicides might be served as eco-friendly alternatives to control C. gloeosporioides. This study aimed to invesitigated the effect of plant extracts from clove flowers, fennel seeds, basil, sweet basil, and citronella on growth inhibition of C. gloeosporioides in-vitro and in-vivo. Data were analyzed using Analysis of Variance (ANOVA). The five plant extracts were able to inhibit the growth of the pathogen C. gloeosporioides in vitro and in vivo. The highest inhibition of the pathogen C. gloeosporioides was basil extract treatment in-vitro compared to the control treatment. The in-vivo treatment, the lowest growth of C. gloeosporioides in fennel extract and was significanly different compared to the control treatment.

Abstract

Endophytic fungi are fungi that inhabit the internal tissues of plant and belong to a group of microorganisms reported to have beneficial effects on plants. In this study, three endophytic fungi isolated from rice plant tissue were identified as Trichoderma asperellum, Curvularia chiangmaiensis, dan Fusarium solani. These three fungi have the ability to produce IAA between 3.03 to 6.00 µg/mL. For phosphate solubility assay, all endophytic fungi showed a clear zone around the colonies in Pikovskaya medium and could dissolve phosphate in the range of 2.74 to 17.61 µg/mL. In addition, in vivo observations of the inoculation endophytic fungi can reduce the intensity of blast disease in rice plant. So that, it can be seen that the three fungal isolates can become plant growth promoting fungi and can also used as bicontrol agents for blast disease in rice plant.

Abstract

Brown spot disease is the most serious rice disease due to its destructive nature, wide distribution and presence of several physiological races of the organism. In Asia, the disease has been recorded to reduce crop yields vary broadly from 6-90%. The application of endophytic fungi is reported to increase plant resistance from the secondary metabolites produced. The resulting metabolites are synthesized compounds to maintain their existence in interacting with the environment. The aim of this study was to obtain endophytic fungi of rice plants that were able to suppres Helminthosporium sp. pathogens. Isolation of endophytic fungi was carried out from the roots, peniles, leaves and leaf sheath of rice plants. Identification of endophytic fungi was based on their macroscopic, microscopic characters and molecular identification. Endophytic fungi that had the highest inhibition were T. asperellum, F. nirenbergiae, and F. oxysporum as indicated by the in vitro antagonism test. T. asperellum, F. nirenbergiae, and F. oxysporum also produced IAA hormone between 1.8 to 4.365 mg/L.
