Nineteen safflower genotypes (Carthamus tinctorius L.) that originated from different geographical regions were screening for their response to infection with Macrophomina phaseolina, the charcoal rot pathogen at the research farm of Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Iran, in 2005. The plants were evaluated for length and width of necrotic lesion at the e...
Macrophomina phaseolina and Sclerotinia sclerotiorum are two significant fungal pathogens of sunflower. M. causes charcoal rot ashy stem blight in several important crop species. white mold disease which can occur as middle stalk rot, head premature plant death. Due to the wide host range their survival structures, rotation cannot provide sufficient protection against them. In our experiment, w...
بیاری ساق سیاه خربزه (charcoal rot) ناشی از macrophomina phaseolina (tassi) goid. یکی از عوامل مهم خسارتزا در گیاه خربزه می باشد. قارچ عامل بیماری از مزارع مناطق ورامین و ایوانکی جداسازی و بیماریزایی آن روی خربزه به اثبات رسید. در بررسیهای آزمایشگاهی جدایه های trichodeama harzianum و t.viride با قدرت رقابت غذایی و هیپرپارازیتیسم قوی از رشد کلنی ماکروفومینا در محیط کشت متقابل (dual culture) جلوگ...
In 2019 and 2020, charcoal rot symptoms were observed on lentil plants in fields located the Northwest of Algeria (Mascara Tiaret Relizane). Based morphological molecular identification using internal transcribed spacer (ITS) sequence analyses, two representative isolates identified as Macrophomina pseudophaseolina. Pathogenicity tests performed Koch’s postulates verified fulfilled. To our know...
ABSTRACT Cowpea [Vigna unguiculata (L.) Walp.] is an important socioeconomic crop in Brazil, mainly the Northeast and more recently Midwest of Brazil. Charcoal rot caused by Macrophomina phaseolina (Tassi) Goid, disease semiarid regions, where edaphoclimatic conditions are favorable to development disease. The aim this study was evaluate response 100 cowpea lines two isolates M. phaseolina. exp...
Charcoal rot is a fungal disease that thrives in warm dry conditions and affects the yield of soybeans and other important agronomic crops worldwide. There is a need for robust, automatic and consistent early detection and quantification of disease symptoms which are important in breeding programs for the development of improved cultivars and in crop production for the implementation of disease...
