“…Activities of exudations from the sclerotia explain the pathogenic significance of a soil borne fungus (Filnow & Lockwood, 1983). It affects the basal internodes and fibro-vascular system of the roots, impends the transport of nutrients and water uptake causes wilting, loss of vigor, premature dying and limit yields are distinctive features of M. phaseolina infection and also responsible for seedling blight, damping off, early maturing, root and basal stem rot are the characteristic symptoms (Yang & Owen, 1982;Hoes, 1985) in which high losses have been reported due to the availability of low relative humidity and high atmospheric temperature (Tikhonov et al, 1976). Plant pathogenic fungus Rhizoctonia solani is distributed in soils worldwide (Harveson, 2003) causing symptoms of a wide range of hosts (Sneh et al, 1991) producing damping-off, foliar blight, root and crown rot (Windels & Nabben, 1989) as well as delay emergence and reduced yields (Errampalli & Johnston, 2001).…”

The aim of this study was to assess fungicidal potential of homeopathic globules namely Thuja occidentalis and Arnica montana (30C) on plant growth and root infecting fungi particularly Rhizoctonia solani, Fusarium spp. and Macrophomina phaseolina. Both in vitro and in vivo experiments had found positive results in the suppression of root rot fungi. Investigation on present study showed that A. montana and T. occidentalis globules (100, 75 and 50% v/w concentrations) reduced disease intensity caused by root rot pathogens and improved growth of test plants, but it produces negative effects on leguminous test crops in which nodules were failing to produce.

Macrophomina phaseolina (Tassi) Goidanich can cause serious yield losses in several plant species. Investigations were made on the colony morphology of fifty Macrophomina phaseolina isolates from Hungary, one from Spain and two from Serbia on six different culture media to detect differences between the isolates. The fungus exhibited the most intensive growth on maize-flour agar, followed by the Sabouraud-glucose, maltextract, potato-dextrose, Czapek-Dox and watery agar media. Investigations on the macromorphology of the isolates revealed different extents of aerial mycelia formation and differences in the zonal structure of microsclerotial formation on the individual media. One isolate (Mp 38) turned the Sabouraud-glucose agar medium pale pink. Investigations on the micromorphology of the cultures showed that the isolates also varied with respect to microsclerotial characters (size, shape and production of microsclerotia). The microsclerotia of this fungal pathogen had the greatest diameter (averaging 135.31 μm) on Sabouraud-glucose agar medium. This study was the first in Hungary to prove that Macrophomina phaseolina could be grown on nutrient-deficient watery agar, suggesting that it can tolerate a wide range of ecological circumstances.
