The fungus Macrophomina phaseolina is a phytopathogen of great importance attacking various crops and causing severe losses especially in sorghum, beans, soybeans others. Since acetic indole acid (AIA) hormone that some authors associate with the pathogenic power other fungi such as Fusarium oxysporum, it was decided to perform this work detect whether M isolated from beans layers producing AIA...
charcoal rot disease, caused by macrophomina phaseolina has become a restrictive agent for annual crops in iran. the disease incidence reaches up to 90 percent in some infested areas. high air temperature and drought stress associated with this disease, are the main factors for increasing the disease incidence and severity. in order to isolate the pathogenic agents, pieces of infected root and ...
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...
Induction of systemic resistance by neem cake (Azadirachta indica) and endophytic Pseudomonas aeruginosa, a plant growth promoting bacterium, was evaluated in cotton (Gossypium hirsutum L.) under salinity stress and fungal infection. The combination of biocontrol agent and organic matter induced tolerance against fungal infection (Macrophomina phaseolina) and salinity stress (EC= 17.3 dS, m) by...
در در این تحقیق، از دو قارچ اندوفیت ریشه (sebacina vermifera و piriformospora indica) و دو گونه تریکودرما (t. viride )و trichoderma harzianum (t-100) علیه قارچ macrophomina phaseolina استفاده گردید . توانایی آنتاگونیستی قارچ های اندوفیت ریشه و گونه های تریکودرما از طریق آزمایش های درون شیشه ای و به کمک روش کشت متقابل، کلنیزاسیون و تولید متابولیت های فرار مورد ارزیابی قرار گرفت مساحت پرگنه m. ph...
یکی از مهم ترین بیماری های گیاه روغنی آفتابگردان در استان گلستان، پوسیدگی ذغالی است که توسط قارچ خاکزی macrophomina phaseolina ایجاد می شود. تاکنون راه حل قطعی و مؤثری جهت مبارزه با این بیماری یافت نشده است و تنها روش معقول و به صرفه، استفاده از ارقام مقاوم است. بر این اساس، میزان مقاومت هجده رقم مختلف متداول و توصیه شده برای منطقه، در قالب طرح بلوک های کامل تصادفی در برابر جدایه هایm.phaseoli...
on the basis of preliminary in vitro screening tests, a competent strain of pantoea agglomerans ena1 (p. agg. ena1) recovered from soybean nodule was evaluated for its antagonistic activity against macrophomina phaseolina causal agent of charcoal rot of soybean. the results of various in vitro assays showed that p. agg. ena1 is capable of exerting strong antagonistic effect against m. phaseolin...

This paper reported on the various filamentous fungi strains that were isolated from a wild grown Catharanthus roseus. Based on the morphological characteristics and molecular technique through a Polymerase Chain Reaction and DNA sequencing method using internal transcribed spacer (ITS), these fungi had been identified as a Colletotrichum sp., Macrophomina phaseolina, Nigrospora sphaerica and F...
