Abstract

Endophytic bacteria have potency as candidates of biological control agents to plant disease, because the bacteria as reported to be associated with plant resistance to pathogens. The study aimed to determine the ability of endophytic bacteria to inhibit the growth of Sclerotium rolfsii in vitro, and suppress damping off disease incedence and Sclerotium wilt disease severity on soybean. The ability of endophytic bacteria to inhibit S. rolfsii was carried out on 44 isolates that isolated from soybean, rice and banana. The ability of endophytic bacteria to control damping off disease was carried out on 13 isolates were selected in vitro (BE-CW1, BE-M1, BE-M2, BE-M3, BE-M4, BE-S1, BE-S6, BE-S13, BE-S14, BE -BRRG2, BE-KH1), and also fungicides and two controls (healthy plant and diseased plant). The ability of endophytic bacteria to control Sclerotium wilt was carried out on 6 isolates which showed pressure on damping off disease (BE-M1, BE-M2, BE-M3, BE-M4, BE-CW1, BE-KH2) and 2 controls (healthy plants and diseased plants).The results showed that the thirteen isolates of endophytic bacteria could inhibit mycelial growth and germination S. rolfsii. Soybean seed treatment revealed that dipping the seed in endophytic bacterial isolates suppressed damping off disease incedence with a range of 37.4 to 49.9% and Sclerotium wilt disease severity of 20.1 to 85 % , as well as reduced the mortality of soybean by 26.3 to 84.4 % . BE-KH2 isolate was able to suppress Sclerotium wilt in soybean by 85% and reduce the mortality by 67.5%.

Abstract

Pudak Village, Kumpeh Ulu District, is one of the rice producers in Muaro Jambi Regency, with a paddy field area of up to 180 ha. Even so, there are obstacles that often-become inhibiting factors for farmers to increase rice production. One of them is the problem of fertilizer which is always difficult for farmers in almost every growing season, besides that the attack of plant-disturbing organisms also becomes a barrier for farmers to get optimal results.Utilization of agricultural wastes such as remaining rice straw, husks, household organic waste can be an alternative that can reduce the use of synthetic fertilizers, because they are easy to obtain, inexpensive, environmentally friendly, and economical in production costs. Making compost and pesticides with active ingredient Trichoderma sp. is one of the decomposers used to utilize organic wastes around homes and agricultural land.Public service activities can increase farmers' knowledge about biological agents or antagonistic microorganisms in the form of the fungus Trichoderma sp. The method used is in the form of counseling on how to get the fungus Trichoderma sp. around farmers' land, the benefits of these antagonistic fungi are both as biological agents and decomposers, propagation techniques for application in the field. and how to apply it to rice plants. This PPM activity was able to increase farmers' knowledge about the benefits of the fungus Trichoderma sp. Apart from being a decomposer, it can also be used as a biological agent to control pests and plant diseases and can support environmentally friendly and sustainable agriculture. Keywords: Antagonistic Fungi; decomposer; Trichoderma sp.; Biological Agents

Abstract

The purpose of this study was to determine the type and level of parasitoidparasitization larvae of P. xylostella on mustard greens (B. juncea). This research was carried out from August to October 2022 in the Lingkar Selatan Village, Jambi City and Tangkit Village, Muaro Jambi Regency. Identification of types of parasitoids and calculation of parasite levels were carried out at the Laboratory of Plant Pests, Faculty of Agriculture, Jambi University. For each green mustard planting area in the two study locations, 3 random sample plots were determined. The technique for determining sample plants uses a systematic random method with a pattern of plant lanes. Sampling of P. xylostella larvae was carried out at the age of 4, 9 and 13 days after planting (DAP). The larvae of P. xylostella were reared in the laboratory to find out the parasitoids that appeared, then identified based on their morphological characteristics. The type of parasitoid larvae of P. xylostella found in both study locations was Cotesia plutellae. The level of parasitoid parasitization in the Lingkar Selatan Village was always higher at various ages of plants with an average of 39.92% compared to Tangkit Village, which was 12.4%.Keywords: mustard greens,P. xylostella, Cotesia plutellae,level of parasitoid parasitization
