Selection and application of a VAM-fungus for promoting growth and resistance to charcoal rot disease of sunflower var. helico-250

摘要

Of the 7 VAM-fungi. Scutellispora auriglobosa was found consistently associated with sunflower var. Helico-250. Sunflower plants suffer from charcoal rot disease caused by Macrophomina phaseolina. Ten days old sunflower seedlings when inoculated with M. phaseolina either before or after 7 days of inoculation with the VAM-fungus were found to increase the growth of sunflower with reduction in the incidence of charcoal disease.
