macrophomina phaseolina is one of the major yield limiting factors of melons in tropical and subtropical regions. for eco-friendly and effective management of the disease, 24 gamma induced mutants from trichoderma harzianum were evaluated against three isolates of the pathogen representing three geographically different regions viz. khorasan (isolate 1), garmsar (isolate 2) and khuzestan (isola...

Macrophomina phaseolina, phylum Ascomycota, is a phytopathogenic fungus distributed worldwide in hot dry areas. There are few studies on its secreted lipases and none on its colony radial growth rate, an indicator of fungal ability to use nutrients for growth, on media other than potato-dextrose agar. In this study, 13 M. phaseolina isolates collected in different Brazilian regions were screene...

Roselle (Hibiscus sabdariffa L.) family Malvaceae is an important crop used in food, cosmetics and pharmaceutics industries. Roselle is cultivated mainly in Upper Egypt (Qena and Aswan governorates) producing 94% of total production. Root rot disease of roselle is one of the most important diseases that attack both seedlings and adult plants causing serious losses in crop productivity and quali...

macrophomina phaseolina is an important soil-borne pathogen causing charcoal rot in many important crop plants including sesame, in iran. a total of 60 isolates of m. phaseolina were collected from the main sesame producing regions in ten provinces of iran. the genetic diversity among m. phaseolina populations was estimated using inter-simple sequence repeat (issr), focusing particularly on geo...
