Abstract

Cayenne pepper (Capsicum frutescens) and red chili (Capsicum annuum), including vegetables and fruit are widely consumed by the public, and also have many benefits. At present, the market demand for cayenne pepper and red chili is very high, so equalization must be made from the production sector. The conventional way of handling such as the administration of pesticides or other chemicals is less effective because it causes side effects that have a large enough impact, so an alternative technique is used that is to use Arbuscular Mycorrhizal Fungi (FMA) thus, research on the administration of Arbuscular Mycorrhoid Fungi Inoculum is thus carried out. (FMA) Mixture of Sclerotium Stem Rot Rotation in Capsicum frutescens and Capsicum annuum. The purpose of this study was to determine the effect of mixed FMA inoculums in suppressing the intensity of sclerotium stem rot rot disease in cayenne pepper (Capsicum frutescens) and red chili peppers (Capsicum annuum) and to determine the optimal dose of mixed AMF in suppressing the intensity of sclerotium stem rot rot on cayenne plants (Capsicum frutescens) and red chili plants (Capsicum annuum). This study used a Completely Randomized Design (CRD) with different doses of mixed AMF inoculums (0, 10, 15, 20, 25 g FMA with zeolite / plant carrier medium). The results of this study indicate that the treatment of mixed AMF inoculums on the intensity of sclerotium stem rot disease in cayenne and red chili plants can reduce the intensity of Sclerotium stem rot disease by 22% and in red chili plants by 11%.

Abstract

Red chili is a vegetable commodity that has high economic value in Indonesia. Leaf spot disease caused by the fungus Cercospora sp. is one of the limiting factors in red chili production. The occurrence of leaf spot disease is determined by the success of the pathogenesis by the fungus Cercospora sp. In addition, red chilies that are resistant to leaf spot disease have higher ascorbic acid content than vulnerable red chilies. The purpose of this study was to determine the ability to grow pathogens Cercospora sp. on the medium which was given ascorbic acid and know the effect of inoculation of the pathogen Cercospora sp. against ascorbic acid content in red chili leaves (C. annuum L.). This study used an experimental design with a completely randomized design (CRD). In vitro tests carried out consisted of PDA and PDB medium which were given ascorbic acid with a concentration of 0 mg.l-1, 0,25 mg.l-1, 0,5 mg.l-1, 0,75 mg.l-1 and 1,0 mg.l-1. In planta testing was using hot chili red chili varieties, large red chili varieties and curly red chili varieties. The treatments that were tested included calculation of disease intensity and ascorbic acid content in red chili leaves. In vitro test the main parameters observed were the diameter colony of the fungus Cercospora sp. dan mycelium dry weight. In planta test the main parameters observed were the intensity of the disease, while the supporting parameters were the incubation period of the disease, the content of ascorbic acid in the red chili leaves, temperature and humidity. In vitro test data obtained were analyzed using Analysis of Variance (ANOVA) at a 95% confidence level, then the treatment that gave a real or very real difference was followed by the Least Significant Difference test (LSD). In planta test data obtained were analyzed using Analysis of Variance (ANOVA) at a 95% confidence level, then the treatment that gave a real or very real difference was followed by the Least Significant Difference test (LSD). The results showed that the pathogen Cercospora sp. able to grow well on the PDA medium and GDP medium which were given ascorbic acid. Inoculation of pathogen Cercospora sp. can increase ascorbic acid content in red chili leaves.

Abstract

Sclerotinia infection of stem and leaf of soybean Glycine max (L.) Merr. caused by the fungal pathogen of Sclerotium rolfsii has recently become more important in the Indonesian soybean production area. This study aimed to evaluate the level of resistance and intensity of infection by S. rolfsii in four soybean strains. The research was arranged in a factorial completely randomized design. The observed variables include the anatomy characteristics of leaves and stems of soybean and disease intensity caused by S. rolfsii. The data were analyzed quantitatively with the Analysis of Variance (ANOVA) at 95% and 99% confidence level, followed by the Least Significant Difference Test (Fisher’s LSD) at the level of 5%. Soybean leaves and stem anatomy inoculated by S. rolfsii showed a decrease in the stomatal density, epidermis thickness, and mesophyll thickness as well as a damaged cuticle, damaged stem epidermis, and swollen stem cortex. Four strains inoculated by S. rolfsii showed a higher disease intensity of 40%-80% compared to the resistant cultivar ('Dering') and susceptible cultivar ('Wilis'), showing disease intensity of 20% and 40%, respectively.
