Abstract

Bacterial leaf blight disease caused by Xanthomonas oryzae pv. oryzae is an important rice disease in Indonesia, including in South East Sulawesi. The use of resistant varieties is one of the effective and environmentally friendly control strategies to suppress the disease. This study aimed to determine the level of resistance of some local rice varieties of South and Southeast Sulawesi against Xanthomonas oryzae pv. oryzae pathotypes IV, VIII and X. The study was conducted in a screen house involving 3 bacterial pathotypes and 11 local rice cultivars. Shearing method was used for inoculation of bacteria to leaf on vegetative and generative phases. Disease incidences were measured 3 weeks after inoculation, and the data was further used to determine the level of resistance of the tested rice cultivars. The results showed that incubation period of the disease was longer on Kelaca cultivar compared to other cultivars. On vegetative phase, this cultivar showed moderate resistant to pathotypes IV and X, and highly resistant to patotype VIII, whereas on the generative phase it showed moderate resistant to pathotypes IV and VII, and highly resistant to pathotype X. Therefore, Kelaca cultivar can be recommended for endemic areas of leaf blight in South and Southeast Sulawesi

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.

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%.
