| Abstract: | Four hundred and eighty six isolates were obtained from 1620 diseased sample plants. Through purification, 19 pathogenic fungi were identified, with Rhizoctonia oryzae and Achlya oryzae being primary species. Nine pathogenic fungi were isolated and identified from the exterior and interior of rice seeds, with Neovossia horrida as the predominant species, followed by Gibberella fujikuroi. Of the 24 fungicides evaluated, five proved more effective in fungous disease control than Fenaminosulf, i.e. Vitavax 200 FF, Rizolex, thiram quintozene, mepronil and pentachloronitrobenzene. |
