Abstract

Downy mildew disease (Maize downy mildew) caused by Peronosclerospora spp. is a major disease in corn that can significantly reduce corn production. An environmentally friendly alternative method to control this disease is the use of botanical fungicides. This study aimed to evaluate the efficacy of botanical fungicides derived from betel leaf extract (Piper betle), Javanese chili leaf extract (Piper retrofractum), and neem leaf extract (Azadirachta indica) in controlling downy mildew disease in BISI-18 corn variety. The research was conducted from January to June 2024. The experimental plots measured 2 x 1.25 m (2.5 m²). Treatments were arranged in a randomized block design (RBD) on a 12 x 9 m plot, consisting of five treatments and six replications (groups). Natural inoculation of the downy mildew pathogen was carried out by placing one symptomatic plant in each experimental plot. Observed variables included incubation period, disease incidence and severity, AUDPC (Area Under Disease Progress Curve), phytochemical analysis, and yield. The results showed that the botanical fungicide from betel leaf extract was the most effective in reducing the intensity of downy mildew, while both betel leaf extract and neem leaf extract were moderately effective in suppressing the AUDPC of the disease. However, all botanical fungicide treatments were ineffective in increasing secondary metabolite content and yield of the BISI-18 corn variety.

Abstract

Penyakit hangus daun (leaf scorch) tebu merupakan salah satu penyakit dengan potensi menimbulkan kehilangan hasil moderat. Penelitian bertujuan mengetahui identitas dan sensitivitas penyebab penyakit hangus daun pada tebu terhadap fungisida bahan aktif karbendazim, mankozeb, dan prokloraz mangan klorida kompleks. Penelitian dilaksanakan dari Juli 2023 sampai Februari 2024 di Laboratorium Disease PT Gunung Madu Plantations (PT GMP), Laboratorium Bioteknologi Pertanian Fakultas Pertanian Universitas Lampung. Sampel tebu bergajala hangun daun diambil dari perkebunan tebu PT GMP. Identifikasi penyebab penyakit hangus daun dilakukan secara morfologi dan molekuler. Uji sensitivitas penyebab penyakit hangus daun terhadap fungisida dilakukan menggunakan metode makanan beracun. Fungisida dan konsentrasi yang digunakan yaitu; karbendazim (0,1 g/100 mL), mankozeb (0,24 g/100 mL), dan prokloraz mangan klorida kompleks (0,25 g/100 mL). Hasil identifikasi secara morfologi dan molekuler menunjukkan bahwa patogen hangus daun tebu di PT GMP adalah jamur Saccharicola bicolor. Hasil uji sensitivitas menunjukkan bahwa jamur S. bicolor bereaksi sangat sensitif terhadap fungisida dengan bahan aktif karbendazim, mankozeb, dan prokloraz mangan klorida kompleks.

Abstract

Anthracnose is a major disease of chili peppers caused by complex of Colletotrichum species. Intensive application of fungicides is the main choice for control anthracnose. This study aimed to evaluate the sensitivity of Colletotrichum spp. to fungicides and determine the effective concentration to control Colletotrichum spp. This study was conducted from March to July 2024 at the Plant Disease Laboratory, Faculty of Agriculture, Lampung University. Anthracnose pathogens were isolated from Tegineneng District, Pesawaran Regency, Lampung Province. Sensitivity tests were conducted using the recommended concentration with poisoned food techniques. The effective concentration determination test was carried out only on fungicides that showed a resistance response using the poisoned food technique. The fungicides tested were those used by farmers in the location where the samples were taken. The sensitivity test results showed that the fungus Colletotrichum spp. from Tegineneng District was highly resistant to propineb. Colletotrichum spp. from locations 3 and 4 are still sensitive to carbendazim, but from locations 1 and 2 are resistant. Colletotrichum spp. from locations 2, 3, and 4 were still very sensitive to mankozeb, while those from location 1 were moderately resistant. The effective concentration of propineb for locations 1, 3, and 4 was 5x the recommended concentration, and for location 2 was 4x the recommended concentration. The effective concentration of carbendazim for location 1 was 5x the recommended concentration, and for location 2 was 2x the recommended concentration. The effective concentration of mancozeb fungicide at location 1 was 2x the recommended concentration.

Abstract

This study aims to analyze the effect of artificial light intensity on hydroponic vegetable production during the rainy season. Limited sunlight during the rainy season often reduces plant growth and productivity. An experimental method using a randomized block design with four light intensity treatments was applied. Observed parameters included plant height, leaf number, fresh weight, and harvest yield. Data were analyzed using variance analysis. Results indicated that artificial light significantly improved plant growth and production. Moderate to high light intensity treatments showed optimal results by supporting photosynthesis efficiency. The findings suggest that artificial lighting can serve as an effective strategy to stabilize hydroponic vegetable production during low natural light conditions. In conclusion, appropriate artificial light management enhances hydroponic productivity during the rainy season.
