Research ArticleOpen accessPhrase in the titleIn Vitro Antagonistic Antifungal-Activity of Streptomyces Isolate 339 Against Magnaporthe oryzaeM. Ebrahimi Zarandi, G. H. Shahidi Bonjar, F. Padasht DehkaeiBiological control offers an environmentally friendly alternative to the use of antimicrobials for controlling plant diseases. A collection of about 100 Actinomycete strains was screened for the ability to produce metabolites that inhibit Magnaporthe oryzae growth in vitro. The Streptomyces isolate 339 showed strong in vitro antagonistic activity against M. oryzae in Agar disc and Well-diffusion methods by producing extracellular … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 3 · 4 Sep 2013 · 8,140 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleBiological Control of Rice Blast (Magnaporthe oryzae) by use of Streptomyces sindeneusis isolate 263 in GreenhouseM. Ebrahimi Zarandi, G.H. Shahidi Bonjar, F. Padasht Dehkaei et al.Soil Actinomycetes particularly Streptomyces spp. have antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. In search for finding such principles, in vitro suppression of Magnaporthe oryzae the causal agent of rice blast disease was studied by use of Streptomyces sindeneusis isolate 263 in greenhouse. Spray of rice seedling-leaves … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 11,492 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleEffect of Seaweed Extracts on Rice Growth and Tolerance to Salinity, Drought and Blast (Magnaporthe oryzae)Mir Sayeada Alam, Jannatun Nayeema, S. M. Rafiquzzaman, Motaher HossainRice, a primary staple, confronts a multitude of biotic and abiotic stresses. Drought and salinity, exacerbated by climate change and blast disease caused by Magnaporthe oryzae, significantly contribute to yield losses. To tackle the problems, two types of seaweeds-one known as Hypnea musciformis and another unknown-were collected from Saint Martin, Cox's Bazar, Bangladesh and then examined for the potential of … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 31 May 2024 · 6,506 accessesView PDF Cite

Research ArticleOpen accessIn the abstractScreening of Blast Resistance Genes from South Tapanuli Rice Cultivars, North Sumatra, IndonesiaSaleha Hannum, Hesti Wahyuningsih, Riyanto Sinaga et al.Rice blast disease caused by a phytopathogenic fungus, Magnaporthe oryzae, has been considered as a major threat to global rice productivity, including Indonesia. South Tapanuli is a regency in North Sumatra, known for its intensive and significant rice production activities. A collection of 13 rice cultivars originating from the region, is claimed for its resistances against the rice blast disease … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 25 May 2020 · 7,537 accessesView PDF Cite
