Abstract
Several fungicides separately and mancozeb in combination with each of five different adjuvant materials were field-tested for effectiveness in reducing brown spot of wild rice (Zizania aquatica ) caused by Drechslera oryzae (Bipolaris oryzae ) and D. sorokiniana (B. sorokiniana ). The fungicides were applied on wild rice plants at 14-day intervals from early flowering until 26 days before harvest. The following fungicides significantly controlled brown spot (114 L of spray per hectare): benomyl 50WP at 1.1 kg/ha; chlorothalonil 6F at 2.9 kg/ha; mancozeb at 2.3 kg/ha; fenapanil (RH-2161) 50WP at 0.6 kg/ha; and iprodione (RP 26019) 50 flowable at 6.4 kg/ha.
