blast (magnaporthe grisea) is the most important disease of rice in mazandaran province, north of iran, which causes severe damages annually on susceptible cultivars. tarom mahalli is a local aromatic cultivar with high cooking quality and marketability, but very susceptible to blast. to protect this cultivar and similar susceptible cultivars against rice blast, farmers have to use high amounts...
grain yield loss in rice (oryza sativa l.) caused by blast disease, magnaporthe grisea (hebert) barr, is a major concern of rice growers worldwide. blast is considered as the most injurious disease of rice in iran, resulting in severe loss especially to susceptible rice cultivars. in order to assess yield loss caused by blast pathogen and develop an appropriate model, different disease onsets a...
Shahbazi H, Tarang A, Padasht F, Hosseini Chaleshtari M, Allah-Gholipour M, Khoshkdaman M, Mousavi Qaleh Roudkhani SA, Nazari Tabak S, Asadollahi Sharifi F, Pourabbas Dolatabad M (2022) The reaction of 109 rice lines to blast disease. Plant Pathology Science 11(1):24-35. Doi: 10.2982/PPS.11.1.24. Introduction: Blast caused by Pyricularia oryzae is the most important fungal disease of ri...
to determine rice yield loss resulting from blast disease (magnaporthe grisea) at the corp's different growth stages, a field experiment was conducted at the rice research institute of iran, rasht. rice local cultivar hashemi was transplanted to 3×4m plots for the experimental treatments (time of disease evaluation) each treatment was replicated 4 times. under natural infection conditions,...
Blast, caused by Magnaprthe grisea, is often an important fungal disease in the production of rice in temperate and tropical areas including Iran. To determine reaction of rice cultivars against blast disease, 40 rice genotypes from Iran and other sources from Asia were selected. Four blast isolates from different races were used to test all rice genotypes in different greenhouse tests. In bl...

Rice cultivar Tarom Dilamani becauded a fragrance, flavor, cooking and marketing is a qualitative rice in Iran. This cultivar have high susceptibility against blast disease (Magnaporthe grisea). One of the important trouble producers of the Dilamani's rice cultivar is chemical control against blast disease and cause poisonous pollution of natural environment. The best manner in order to control...
blast disease of rice caused by pyricularia oryzae is a potentially damaging disease in northern due to planting of susceptible local cultivars and favorable conditions. to assess the effects of blast on rice yield components and yield loss, one field experiment was conducted at the lowland culture conditions. analysis of blast effects on rice indicated that the maximum yield losses due to unpr...
Systemic properties of pyroquilon, an anti-blast systemic chemical, used in controlling rice blast disease caused by Pyricularica grisea, was investigated through in vivo tests. Rice plants were treated with pyroquilon as granules in soil. Leaf and stem tissues were collected at different times after treatment and pyroquilon was extracted from tissues and detected by gas chromatography. Treated...
