Metallic silver nanoparticles have been reduced from silver nitrate by employing the extracellular enzymatic machinery of edible White button Mushroom (Agaricus bisporus). The physical properties of these particles, size and shapes have been determined using techniques like TEM, FTIR and XRD and were reported in our earlier report. But, what stands of paramount importance in the presen...

The fungus Macrophomina phaseolina is the causal agent of charcoal rot in many crops, such as strawberries and beans. Symptoms include stem root chlorotic foliage. This disease’s management complicated because pathogen forms resistant microsclerotia. work aimed to obtain bacterial isolates for biocontrol M. arid regions. Two strains that grew well under low pH high salinity, named BsA3MX BsC11M...

Macrophomina phaseolina (Tassi) Goid., a pycnidia-producing fungus, is one of the most important soilborne pathogens, infecting over 500 plant species in more than 100 plant families around the world (1,18). It causes a major disease of soybean (Glycine max (L.) Merr.) called charcoal rot (18). Symptoms on soybean include blight of emerging seedlings, wilting, early maturation, and incomplete p...

In this study, we identified the causative agent of stem-end rot in potatoes that were grown in Gangwon alpine areas of Korea in 2013. The disease symptoms included appearance of slightly sunken circular lesion with corky rot on the potato surface at the stem-end portion. The fungal species isolated from the infected potatoes were grown on potato dextrose agar and produced white aerial mycelia ...

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 ...
