Abstract

This research motivated by the Fusarium oxysporum which is a soil borne fungus that can infect cultivated plants. F. oxysporum is a facultative parasite that is part of its life as a saprophyte and becomes a parasite if there is a host plant. This study aims to determine the potential of endophytic bacteria from wild plants as biological agents control of F. oxysporum in-vitro. This research was conducted at the Laboratory of Plant Protection, Phytophatology Unit, Faculty of Agriculture, Halu Oleo University from September 2020 to March 2021. The results showed that endophytic bacteria isolated from wild plants such as as Jamaica cherry/kersen (Muntingia calabura), Suruhan (Paperomia pellucida), and Markisa Hutan/Rambusa (Passiflora foetida) have the potential as biological agents to control F. oxysporum in vitro, with the two best isolates, namely ASR-7(3) and BK-3(2) which were to inhibit the growth of F. oxysporum through the mechanism of antibiosis and competition, produced enzyme bioactive compounds (amylase and protease) which degrade of pathogenic fungi, and are able to produce volatile compounds.

Abstract

The success of foot rot disease control is largely dependent on information data of pepper cultivation conditions, distribution pattern of the disease, and the magnitude of the intensity of the disease. This study aimed to determine the condition of pepper cultivation, distribution pattern of pepper foot rot disease, the development of disease symptoms, and intensity of pepper foot rot disease in Southeast Sulawesi. Data cultivation conditions, distribution of the disease, progression of symptoms, and the intensity of the disease were obtained by means of surveys in pepper plantations and interviews with pepper farmers. The results showed that the pepper plantations in Southeast Sulawesi were cultivated on flat to hilly topography, and the cultivation method was very conventional but herbicide use was very intensive. The development of wilt symptoms on pepper plants was very quick in dry weather but slow in the wet. Pepper foot rot disease has patch distribution. The highest intensity of the pepper foot rot disease was in less weedy plantations with intensive use of herbicides. The intensity of the pepper foot rot disease in Southeast Sulawesi was 61,2% with the spread in each district namely South Konawe at 53,8%, Konawe at 63,7% and Kolaka by 61,2%.

Abstract

Rice is the main food crop in Indonesia, and plant health greatly affects production. Farmers in Lebo Jaya Village, Konda Subdistrict, South Konawe Regency, still use traditional cultivation techniques such as scattered planting systems and minimal liming and intensive fertilization, resulting in low levels of rice plant health. Digital image processing technology offers a more efficient and accurate alternative in diagnosing plant health compared to traditional methods. This study aims to evaluate the differences in the health level of paddy rice plants using different planting systems and cultivation technology inputs in Lebo Jaya Village based on digital image processing. The methods used include field surveys, recording, and image processing of rice plants of the Inpari 32, Ciliwung, and Inpari 33 varieties managed by farmers and HKTI-Sultra (Association of Indonesian Farmers Harmony-Southeast Sulawesi). The results showed that rice plants managed by HKTI-Sultra with a more advanced planting system and cultivation technology inputs had a higher level of health compared to rice plants managed by local farmers. Digital image processing technology proved effective in detecting and evaluating the health of rice plants based on differences in cultivation systems.

Abstract

Phytophthora capsiciis a causal agent for footrot disease in pepper and classified as a soil-borne pathogen. The inoculums of P. capsici in the soilis difficultto detect. The dynamics of P. capsici population in the soil is frequently and rapidly fluctuates and hard to detect, causing the pathogen to produce disease rapidly. The aimsof this research were todetect the pathogen P.capsici using black pepper leaf baiting and to quantify the inoculum of the pathogen P.capsici in the soil belonging to several disease intensities of the black pepper foot rot in the field. The first experiment: detecting the pathogen P. capsici using black pepper leaf baiting in the soil artificially infested using several sporangia, anda second experiment: quantification of propagul of the P.capsici in various categories of intensity on the black pepper foot rot disease in the field. The research results showed that the black pepper leaf baiting could be used to detect the existence of the propagul of P.capsiciin the soil artificially infested in various densities of sporangia.  The increase in disease intensity occurred in parallel with the greater density of P. capsici inocula in soil. The density of P. capsici inocula in the soil tended to decline when the disease intensity reached the highest level.

Abstract

This research aims to determine the effect of using endophytic bacteria from wild plants in the biological control of Fusarium Wilt disease on tomato plants and to find out which isolate method is best for controlling Fusarium Wilt disease on tomato plants. The research was carried out at the Plant Protection Laboratory, Phytopathology Unit, and Experimental Garden Greenhouse 1, Faculty of Agriculture, Halu Oleo University, Kendari, from September to November 2022. This research used a Randomized Block Design (RBD) with 5 treatments repeated 3 times for a total of 15 treatment units. The variables observed were divided into 2, namely vegetative plant growth (plant height, number of leaves, and number of productive branches) and the incidence of Fusarium Wilt disease on tomato plants. The data was analyzed using variance and if there was a real influence, it was continued with the Duncan Multiple Range Test (DMRT) at a confidence level of 95%. The results of the research showed that endophytic bacteria from wild plants were able to increase plant growth and control Fusarium Wilt disease in tomato plants and ASR-3(2) isolate was the best isolate in increasing plant growth and controlling Fusarium Wilt disease.

Abstract

Chili is one of the important vegetables that are cultivated commercially in tropical countries with various benefits. One of the important diseases of chili plants is jaundice caused by Begomovirus or gemini virus. The disease is transmitted through a whitefly (Bemisia tabaci). The research aims to evaluate the ability and number of whitefly insects that can transmit the gemini virus to chili plants. The research was carried out using a group random design (RAK), 4 treatments each treatment was repeated 5 times. The treatment consisted of no inoculation of whitefly on plants (S0), inoculation of 1 whitefly/plant (S1), inoculation of 3 whitefly/plant (S2) and inoculation of 5 whitefly/plant (S3). The variables observed were vegetative growth, incidence and severity of disease. The presence of the whitefly (B. tabaci) increases the incidence and severity of jaundice and inhibits growth in cayenne pepper plants (C. annuum). The transmission of the gemini virus is faster with the inoculation of 5 ticks/plant with the highest incidence and severity of the disease.

Abstract

Analysis of land suitability and economic feasibility is a way that can be done to plan the development of food crops on rocky land. The research was carried out in Gu District, Central Buton Regency and soil analysis was carried out at the Integrated Laboratory of Halu Oleo University. The research method is a free survey method, land observation type is through drilling and socio-economic data is collected through filling out questionnaires and interviews with farmers. Land suitability analysis is carried out in actual conditions and land suitability after improvements have been made. The assessment is carried out by matching land characteristics with plant growth requirements. The economic parameter used to assess the feasibility of farming annual crops is the ratio of revenue to total production costs Revenue Cost Ratio (R/C). The results of the research show that the development of food crops is based on an analysis of land suitability and financial feasibility, namely the very suitable and very feasible category reaching 485.68 Ha, quite suitable and quite feasible reaching 3,568.69 Ha and not suitable and not feasible reaching 2,305.88 Ha. Directions for planting field rice, corn or soybeans by applying liming technology, applying organic material, nitrogen and phosphorus fertilization, making terraces and planting in the direction of the contour.
