Abstract Background Safe food free from diseases is the world's goal. Excessive usage of chemical fungicides considered most important danger for climate. Natural alternatives with low costs have become best choice sustainable agriculture. Results In context researching green materials instead fungicides, fabrication nano- Sargassum vulgare and its composite zeolite was carried out. Followed by...
ناترک گیاهی از خانواده Sapindaceae بوده که به عنوان گیاه زینتی با خواص دارویی فراوان شناخته می‌شود.گسترش عارضه پوسیدگی طوقه و ریشه این گیاه در چند سال اخیر باعث از بین رفتن آن در اکثر مناطق استان خوزستان شده که این امر سبب جایگزینی این گیاه با سایر گیاهان زینتی در اکثر فضاهای سبز شهری و بلوارها گردیده است. به منظور شناسایی و تعیین پراکنش قارچ‌های همراه با پوسیدگی ریشه و طوقه ناترک طی سال 1390 ...
Several species of the genus Dickeya provoke soft rot and blackleg diseases on a wide range of plants and crops. Dickeya solani has been identified as the causative agent of diseases outbreaks on potato culture in Europe for the last decade. Here, we report the complete genome of the D. solani IPO 2222T. Using PacBio and Illumina technologies, a unique circular chromosome of 4,919,833 bp was as...
Soreshin of cotton was more severe from combined infections of Rhizoctonia solani and Meloidogyne incognita than from either organism alone, when both critical soil temperature and inoculum concentrations were present. Optimum soil temperatures for disease development from combined infections were 18 and 21 C. Either 2,500 or 5,000 M. incognita larvae per plant, combined with R. solani, increas...
this study was carried out to identify fusarium species associated with sugar beet root rot and yellows. pathogenicity of fusarium oxysporum, the causal agent of fusariumyellows of sugar beet was also investigated. samples of infected roots were collected from fields in major sugar beet producing areas in khorasan province during 1999-2000. infected roots were washed, surface sterilised and pla...
objective: fusarium diseases that cause grain mold and stalk rot of millet are the most important diseases, of these crops in iran. fusarium can cause stalk rots, ear rots, and grain mold, resulting in serious production losses in millet, and produce mycotoxins that are harmful to both humans and domesticated animals. methods: a total of 23 fusarium isolates were recovered from foxtail millet ...
Rhizoctonia solani is a soil-borne fungus causing sheath blight. In consistent with its necrotrophic life style, no rice cultivars fully resistant to R. solani are known, and agrochemical plant defense activators used for rice blast, which upregulate a phytohormonal salicylic acid (SA)-dependent pathway, are ineffective towards this pathogen. As a result of the unavailability of genetics, the i...
Rhizoctonia solani is a nectrotrophic fungal pathogen that causes billions of dollars of damage to agriculture worldwide and infects a broad host range including wheat, rice, potato and legumes. In this study we identify wheat genes that are differentially expressed in response to the R. solani isolate, AG8, using microarray technology. A significant number of wheat genes identified in this scr...
گونه‌های جنس فوزاریوم از عوامل بیماری‌زای گیاهی مهم و اقتصادی به شمار می‌روند. روش‌های رایج کنترل بیماری به تنهایی از کارآیی لازم برخوردار نمی‌باشند، لذا استفاده از استراتژی‌های جایگزین از جمله کنترل زیستی از جایگاه ویژه‌ای در مدیریت بیماری‌های ناشی از این قارچ برخوردار می‌باشد. در این راستا اثر بازدارندگی از رشد سه گونه از قارچ تریکودرما، شامل Trichoderma harzianum, T. longibrachiatum و ...
Chrysanthemum is an important ornamental plant which is increasingly being monocropped. Monocropping is known to affect both fungal abundance and species diversity. Here, quantitative PCR allied with DGGE analysis was used to show that fungi were more abundant in the rhizosphere than in the bulk soil and that the fungal populations changed during the growth cycle of the chrysanthemum. The major...
