“…N,N -diethyl-3-mesitylsulfonyl-l H -1,2,4-triazole-lcarboxamide, is a new herbicide for rice cultivation which especially inhibits germination of monocot weeds, e.g., Echinochloa oryzicola and Cyperus difformis (Kanzaki et al 1999(Kanzaki et al ,2000. Its phytotoxic symptoms, namely impaired seedling emergence and stunting, have been reported as quite similar to those of chloroacetamide herbicides like alachlor or butachlor (Fukazawa et al 1995).…”
