Abstract

Tomato (Solanum lycopersicum L.) is a vegetable commodity whose market demand continues to increase from year to year, so it requires good cultivation management so that the quantity and quality of tomatoes also continues to increase. One of the reasons for the less than optimal production of tomatoes is caused by the fungus Fusarium spp. This study aims to determine the Effectiveness of Soursop Leaf Powder Application with Various Doses of Bokashi Against Fusarium Wilt Disease in Tomato (Solanum lycopersicum L.). This research was conducted at the Plant Protection Laboratory of the Phytopathology and Land Unit I (one) Faculty of Agriculture, Halu Oleo University, Kendari from October 2022 to January 2023 using a Completely Randomized Design (CRD) Factorial 2 Factors. The first factor was soursop leaf powder (T) consisting of control (T0), 50 g soursop leaf powder (T1), 75 g soursop leaf powder (T2). The second factor was bokashi fertilizer consisting of control (B0), 500 g bokashi fertilizer (B1) and 500 g bokashi fertilizer (B2). Thus, 9 treatments were obtained, and each treatment was repeated 3 times to obtain 27 experimental units. The variables observed were the incubation period, disease severity, AUDPC and disease suppression index. The best disease severity interaction was found in the T2B2 treatment with an average disease severity of 33.33%. The effect of the interaction application treatment had a very significant effect on the treatment of soursop leaf flour and bokashi fertilizer with an average incubation period of 63.33% HSI

Abstract

The research aims to determine the main types of pests and the intensity of their damage to chili plants with different cultivation systems. This research was conducted in Konda Satu Village, Konda District, South Konawe Regency. This study consisted of 3 treatments with 6 replications, so there were 18 experimental units. Observational data were analyzed using analysis of variance (ANOVA) and if the results showed significant differences then it was continued with the Least Significant Difference Test (LSD) at the 95% confidence level to find out the best treatment by testing the differences between all treatments. Then test further LSD0.05. This study used three cultivation systems as treatments, namely the Conventional Cultivation System (Without Application of Biofresh Fertilizer + 100% Inorganic recommended dose + Use of Plastic Mulch), Semi-Organic Cultivation System (Application of Biofresh Fertilizer 50% recommended dose + 50% Inorganic of recommended dose + Application Phymar C Botanical Pesticides + Use of Plastic Mulch), and Organic Cultivation Systems (100% recommended dosage of Biofresh Fertilizer Application + Phymar C Botanical Pesticide Application + Organic Mulch). The results showed that the main pests that attack chili plants are armyworm pests (Spodoptera litura), fruit fly pests (Bactrocera sp.) and Aphids pests (Aphididae). The lowest damage intensity of armyworm pests was in the organic cultivation system of 18.08%, the lowest intensity of fruit fly pest attacks was in the semi-organic cultivation system of 31.81%, the lowest intensity of attack by aphids was in the semi-organic cultivation system of 12.59%.

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

Red chili (Capsicum annuum L.) is a vegetable commodity that is widely consumed by Indonesian people, both as a food flavoring and for nutritional fulfillment. one of the reasons for the lack of maximum chili production is caused by fusarium wilt. This study aims to determine the effect of eco-enzyme concentrations on the intensity of F. oxysporum attack on chili plants. This research was arranged using a randomized block design (RBD) in which there were 6 treatments and 4 replications. The treatments were P0 : No treatment (Control), P1 : 1 mL Eco-enzyme/500 mL distilled water, P2 : 1 mL Eco-enzyme/750 mL distilled water, P3 : 1 mL Eco-enzyme/1000 mL distilled water, P4 : 1 mL Eco-enzyme/1250 mL distilled water, and 1 mL Eco-enzyme/1500 mL distilled water. The research variables were plant height, number of leaves, time of appearance of fusarium wilt symptoms, and intensity of fusarium wilt attack. The results showed that the treatment of 1 mL of eco-enzyme/1500 mL of distilled water on the intensity of disease attacks showed that at 10 weeks MST the lowest attack intensity was 1,54%.

Abstract

Colletotrichum sp. is an important pathogen causing anthracnose in chili peppers. Anthracnose can cause yield losses of up to 90%. The control method commonly used by farmers is chemical control, but this method is not environmentally friendly. Endophytic fungi can be isolated from various plants, both cultivated plants and wild plants or weeds. Moringa is a plant that grows well in Southeast Sulawesi and is a vegetable that has excellent benefits due to its high nutritional content and potential as a biological agent. This study aimed to obtain endophytic fungi from moringa that have the potential to inhibit the growth of the pathogenic fungus Colletotrichum sp. in vitro. The research began with the exploration of endophytic fungi from moringa plant tissues. Subsequently, pathogenicity tests, inhibition tests using the dual culture method, and inhibition tests using the volatile compound method were conducted. The results showed that there were 3 (three) isolates of endophytic fungi from moringa that have potential as biological control agents for Colletotrichum sp., namely isolates ED02, EB01, and EB02. Isolate ED02 was the best biological agent for controlling Colletotrichum sp. in vitro, with dual culture inhibition and volatile compound inhibition percentages of 74.10% and 37.45%.

Abstract

Burn disease caused by the fungus Ustilago scitaminea is an airborne pathogen whose spores can be carried by the wind, agricultural tools and people who wear the clothes they wear. The use of resistant varieties is a fairly effective control in controlling smut disease in sugarcane. This study aims to determine the resistance response of sugarcane varieties to smut disease on sugarcane (Saccharum officinarum L.). This research was conducted at the Laboratory of Plant Protection, Phytopathology Unit, Faculty of Agriculture and the Green House of the Faculty of Agriculture, University of Halu Oleo, Kendari. The research design used a completely randomized design (CRD) consisting of 4 varietal treatments namely the Kidang Kencana variety (V1), the Bululawang variety (V2), the green sugarcane cultivar (V3) and the red sugarcane cultivar (V4). The results of this study indicated that disease incidence and disease severity had no significant effect at all observation times (7, 14, 21, 28, and 35 DAP). The longest incubation period with the incidence and severity of the disease was 0% in the V1 and V2 treatments.

Abstract

The association of viral satellite DNA with Begomoviruses influences symptom expression in infected plants. Normalized Difference Vegetation Index (NDVI) is an image processing method used to assess plant health based on the plant’s ability to absorb sunlight for photosynthesis. Therefore, this study aims to assess symptom severity based on symptom variation and NDVI, as well as to detect and identify the presence of beta-satellite DNA associated with chili plants. The study was conducted in North Kolaka Regency, Southeast Sulawesi Province, Indonesia. It involved observations and image recording of symptom variations in the sampled cayenne and big red chili plants, followed by the detection of beta-satellite DNA in the samples using the polymerase chain reaction (PCR). The results confirmed the presence of non-coding satellite DNA associated with the Pepper yellow leaf curl Indonesia virus (PepYLCIV) in all severe, mild, or asymptomatic plant samples. In the phylogenetic tree, the non-coding satellite DNA isolates from Southeast Sulawesi are included in the betasatellite group and exhibit different genetic characteristics from other isolates available in the GenBank database. The cayenne chili with severe symptoms had lower NDVI values than the mild and asymptomatic categories, indicating that this type of chili with severe symptoms had a lower ability to absorb light. Further studies are needed to characterize the alpha-satellite type in the Southeast Sulawesi region for potential use in cross-protection mechanisms against plant virus infections.

Abstract

Whitefly vector insects can spread the Pepper yellow leaf curl Indonesia virus (PYLCIV)  that causes Begomovirus disease. One whitefly can transmit the virus, which belongs to the Begomovirus genus. It is suspected that the more whitefly, the higher the incidence and severity of Begomovirus disease. The increased severity of Begomovirus disease can affect chili yields. This study aimed to assess the relationship between the whitefly population level, the Begomovirus disease's intensity, and the production of chili peppers. The research method used was a survey of the farmers' chili plantations. Observations of the whitefly population and disease intensity were carried out on a scheduled basis. The results showed that the whitefly population affected the incidence and severity of the disease Begomovirus. Each addition of one whitefly/leaf will increase the incidence of disease by 25.981%, the severity by 15.269%, and reduce the yield of chili plants by 40.044 kg/ha. Meanwhile, every 1% increase in the severity of Begomovirus disease will reduce the production of chili plants by 2.867 kg/ha.

Abstract

Tikus sawah (Rattus-rattus argentiventer) dapat menyebabkan kerusakan yang parah pada tanaman padi sawah. Pengendalian dengan fumigasi (pengasapan) berbahan aktif sulfur dapat membunuh tikus dalam lubang pematang. Fumigasi akan efektif bila lubang aktif tikus diketahui, namun mengenali lubang aktif tikus tidaklah mudah. Tujuan penelitian ini adalah mengevaluasi potensi metode Infrared Thermography (IRT) dalam mendeteksi lubang aktif tikus sawah melalui visualisasi citra termal. Beberapa lubang tikus yang ditemukan di areal persawahan milik petani di Desa Lebo Jaya, Kecamatan Konda, Kabupaten Konawe Selatan, Provinsi Sulawesi Tenggara direkam citra termalnya menggunakan FLIR C2 Compact Thermal Imager. Selanjutnya, citra termal dan RGB (red green blue) diolah menggunakan aplikasi FLIR Tools versi 6.4.18039.1003 (FLIR® Systems, USA) dan dilanjutkan dengan analisis suhu rata-rata lubang tikus menggunakan Microsoft Excel. Hasil pengolahan citra termal menunjukkan bahwa area tanah galian lubang tikus yaitu area sisi dalam lubang berwarna lebih gelap yang menandakan bahwa suhu tanah di area tersebut lebih rendah sampai berkisar pada suhu 28 °C, sebaliknya area sisi luar lubang berwarna lebih terang yang menandakan bahwa suhu tanah yang lebih tinggi sampai berkisar pada suhu 32 °C. Metode IRT ini sangat potensial untuk dimanfaatkan sebagai metode deteksi cepat lubang aktif tikus sawah. Implementasinya bersama teknologi drone (UAV) akan mengefisienkan waktu petani saat menandai lubang aktif tikus sawah pada areal persawahan yang luas. Selain itu, pengendalian tikus dengan teknik fumigasi juga akan menjadi lebih efektif dan ekonomis.
