Durante 1996 y 1997 se determinó la reacción de 166 genotipos frijol, en su mayoría cultivados, 237 germoplasma criollo poblaciones silvestres Phaseolus sp., con diversos orígenes, a un aislamiento altamente agresivo Macrophomina phaseolina condiciones invernadero Montecillo, México. Se identificaron mejorados, criollos sp resistentes M. phaseolina. Entre los sobresalen Amarillo Calpan, Manzano...

Catharanthus roseus (L.).G. Don, a highly valued medicinal plant suffers from a serious disease. A survey on the symptom and severity of the leaf blight of C. roseus was performed in the nurseries of the Institute of Forestry and Environmental Sciences (IFESCU), Bangladesh Council of Industrial Research (BCSIR) and Bangladesh Forest Research Institute (BFRI), Bangladesh. An observation was also...

Present study was conducted to evaluate the fungicidal property of methanolic extracts of some indigenous plants of Karachi such as Hibiscus rosa-sinensis (leaves), Thespesia populnea (leaves, stem and fruit), Withania somnifera (leaves and stem), Solanum surattense (shoot) and Melia azedarach (fruit) against common soil-borne phytopathogens viz., Macrophomina phaseolina, Rhizoctonia solani and...

abstract temperature is one of the most important environmental factors affecting on physiological characteristics of fungi. in order to wide host range of macrophomina phaseolina (tassi) goildanich, verticillium dahliae kleb. and sclerotinia sclerotiorum (lib.) de bary, become aware from growth rate and productivity of resistant and survival form of these phyto-pathogens in different temperatu...

Macrophomina phaseolina is a soil-borne fungal pathogen that causes the charcoal rot disease in many plant species. This disease causes many problems to the soy industry as no consistently effective control has been found. Using Medicago as a model, we study the molecular interactions between the pathogen and its plant host. A microarray chip was used to measure the changes in the expression le...

BACKGROUND Random induced mutation by gamma radiation is one of the genetic manipulation strategies to improve the antagonistic ability of biocontrol agents. OBJECTIVES This study aimed to induce mutants with more sporulation, colonization rate leading to enhanced antagonistic ability (in vitro assay) comparing to wild type (WT) and the assessment of genetic differences (in situ evaluation) u...

some types of faba bean suspected of root pathogens in lorestan provincec, iran were sampled during years 2007 to 2008. after some pathogenicity tests, 121 samples which suffered from root fungus disease and from chromista were totally isolated. the abundance of fungi, fusarium solani, which caused the faba bean root rot was more than that of the other separated types and as well as the farming...

Common bean (Phaseolus vulgaris L.) is an important legume with high nutritional value. In Nicaragua, certified healthy seeds of local bean varieties are not available, and seedborne fungi have gained little attention. Here, were surveyed seedborne pathogenic fungi in an important local bean cultivar, 'INTA Rojo'. Beans grown in the four main production areas in Nicaragua (Boaco, Carazo, Estelí...

Charcoal rot of sorghum caused by the fungus Macrophomina phaseolina is a root & stalk rot disease of great destructive potential in most sorghum glowing regions. Improved, high yielding cultivars under great management tends to be very susceptible to the disease. M.phaseolina is a common soil borne, non aggressive and plurevourous pathogen that attacks plants. Whose vigor has been reduced by u...
