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

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

Gejala kuning keriting pada daun cabai umumnya disebabkan oleh infeksi Begomovirus. Daun tanaman terinfeksi tidak hanya mengalami perubahan warna sebagai indikator rusaknya klorofil tetapi juga mengalami perubahan morfologi bentuk. Penelitian ini bertujuan menguantifikasi gejala infeksi Begomovirus berdasarkan perubahan morfologi bentuk daun menggunakan pengolahan citra digital dan algoritma data mining yang akan memudahkan dalam pemantauan dan analisis perkembangan penyakit tanaman. Total 33 citra daun cabai rawit bergejala kuning keriting maupun tidak bergejala menjadi dataset penelitian ini. Citra daun cabai tersebut diolah dan diekstrak karakteristik bentuknya berupa circularity, aspect ratio, roundness, dan solidity menggunakan aplikasi Fiji-ImageJ. Selanjutnya dilakukan uji beda (uji-t), pengelompokan citra menggunakan algoritma Simple K-Means, dan evaluasi ketepatan hasil pengelompokan berdasarkan indeks ARI dan NMI. Hasil penelitian menunjukkan bahwa secara umum ada perbedaan bentuk yang nyata antara daun bergejala dengan daun tidak bergejala. Daun cabai rawit bergejala kuning keriting memiliki rata-rata nilai aspect ratio dan solidity yang lebih kecil dibandingkan daun cabai tidak bergejala, sebaliknya memiliki rata-rata nilai circularity dan roundness yang lebih besar dibandingkan daun cabai tidak bergejala. Evaluasi ketepatan pengelompokan sampel daun cabai rawit bergejala maupun tidak bergejala berdasarkan indeks ARI dan NMI menghasilkan nilai terbaik untuk pengelompokkan ke dalam dua kelompok.

Abstract

The Geminivirus in chili plants is a significant problem in chili cultivation. Symptoms of Geminivirus infection are quite easy to find in chili plants because the symptoms are quite typical: mosaic, yellowing, small leaves, leaf lamina malformation, and stunting. The visual changes in leaf morphology are due to the leaf tissue structure, such as the upper and lower epidermis and the mesophyll tissue, including the palisade and sponge. There is little information about changes in the structure of chili plants infected with the Geminivirus. Therefore, this study aims to add information about changes in the leaf tissue structure of chili plants infected with the Geminivirus. The structural changes observed were palisades. Long palisades were less preferred by whiteflies, so the incidence of geminivirus disease was lower. This information is a reference for assembling chili plants with better structural resistance. The method used was a cross-section of chili leaves, double staining, and observation with a light microscope. Observations on mild symptoms showed epidermal cells shrinking. Some parts of palisade leaves were composed of two layers with shortened cells and tend to be oval. The symptom is that the upper epidermal cells were shrunken, and the palisade also tends to shorten. Severe symptoms of the epidermis on the leaves were curly, shriveled, thinned, and even dying; the palisade is shortened and sometimes looks irregular/tight. Changes in the leaf tissue of chili plants infected with the Geminivirus cause changes at the ultra-structural, cell, or tissue level, depending on the type of virus attack and the attack level.
