In this study ten fungicides were applied to different plot locations that were affected with Rhizoctonia solani (brown patch). The ten fungicides tried were: furmecyclox, PCNB, Pencycuron, triadimefon, etaconazole, netalaxyl, fenarimol, chlorothelonil, benomyl, and iprodione. Furmecyclox, iprodione, B-Ay NTN, and PCNB were applied to plot A and showed a significant amount of control. All fungicides were applied to plot B and all seemed to exhibit good control. There was no difference in test results between the wettable agents and the dry granular agents. All forms of fungicides exhibited problems with phytotoxicity to the St. Augustinegrass. This phytotoxicity lasted during the growing season, but the turf withheld it quite well. In controlling Rhizoctonia solani, PCNB, pencycuron, iprodione, and furmecyclox were the most effective. Furmecyclox and pencycuron are the latest alternative for control of Rhizoctonia-caused diseases. Pencycuron has a minor problem of leaving a white residue which isn"t easily removed. Fenarimol, triadimefon, and etaconazole move into the plant by inhibition of the ergosterol biosynthesis cycle, so these proved ineffective in controlling the Rhizoctonia solani brown patch. The major problem of those compounds that effectivly controlled Rhizoctonia solani was their phytotoxic effect to the St. Augustinegrass.
