Item type:Publication, Bioactivity of teak (Tectona grandis L.f.) and cajeput (Melaleuca cajuputi Powell) leaf extracted on inhibition fruit fungal pathogens(2023-09-01); Results showed that cajeput oil at 10,000 ppm had the highest inhibitory effect on the mycelial growth of all tested fungi, with an inhibition rate of 92.5%. It was followed by cajeput crude extract at 20,000 ppm and teak crude extract at 25,000 ppm, with inhibition rates of 88.6% and 67.0%, respectively. Thus, cajeput oil and cajeput extract showed promising potential in controlling fruit fungal pathogens. Effective concentration (EC<inf>50</inf> and EC<inf>90</inf>) of each extract suggested that the lowest concentration to inhibit mycelial growth, spore germination and spore formation were in between 50-90%, which the concentration range between 100 to 30,000 ppm depending on the extracts and pathogen species. This finding could be useful in evaluating the appropriate concentration of each extract for controlling plant pathogenic fungi.4 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, In vitro assessment of crude extract from Gomphrena weed (Gomphrena celosioides Mart.) for control of plant pathogenic fungi causing chili diseases(2023-03-01); Jaenaksorn, T.The phytochemical screening of both the flowers and other aerial parts of the Gomphrena weed extract (Gomphrena celosioides Mart.) presented alkaloids, flavonoids, saponins, phenolics/tannins, and terpenoids. The extracts from both parts at 80, 160, and 240 mg/ml were significantly inhibited the mycelial growth of C. gloeosporioides and Fusarium sp. compared to inoculated control by paper disc diffusion. The extract from both parts of the Gomphrena weed at the highest concentration (160 mg/ml) significantly showed the greatest inhibitory effect on mycelial growth of Sclerotium sp. (100 percent), followed by C. gloeosporioides (82.5 percent), Cercospora sp. (41.16 percent), and Fusarium sp. (24.41 percent) when tested using the poisoned food technique. The spore germination test revealed both parts of the weed extract yielded concentrations which were completely inhibited (100 percent) on the spore germination of C. capsici, C. gloeosporioides, and Fusarium sp.2 - Some of the metrics are blocked by yourconsent settings
