Isolate of Rhizoctonia solani pathogenic to mungbean, Chinese cabbage,
kenaf, pea, peanut, and wheat was used for the studies on the infection of
ungbean seedlings. Inoculum produced on potato dextrose

found to be the basal parts of hypocotyl where the fungus was frequently
isolated as well as cotyledons. Eight days old stationary culture of the fungus
showed inhibitory effect on the growth of mungbean seedlings. The

demonstrated in water extract of diseased plants. [AS]

In greenhouse tests the best control of Rhizoctonia solani was obtained by
treating soil with 30% quintozene (as a dust), quintozene +
ethoxytrichloromethylthiadiazole (emulsion), and quintozene +
trichloromethylthiobenzoxazolone (dust). [EMS]

The potato charcoal rot caused by Macrophomina phaseoli was studied in
detail. The isolate of potato was pathogenic on Vigna radiata and Vigna mungo,
among other plant species. [THH]
