N2 - Experiments were conducted to evaluate established and seeded buffalograss [Buchloe dactyloides (Nutt.) Engelm.] tolerance to herbicides applied preemergence at labeled use rates. Established buffalograss tolerated benefin, benefin plus oryzalin, benefin plus trifluralin, DCPA, dithiopyr, isoxaben, oryzalin, pendimethalin, and prodiamine. For established buffalograss treated with atrazine, diuron, or metolachlor, the injury rating was 27% to 71% at 6 weeks after treatment (WAT) and 22% to 84% at 15 WAT. Buffalograss tolerated cyanazine, metsulfuron, propazine, and pyrithiobac applied in the seedbed. Seeded buffalograss stands were reduced by alachlor, atrazine, dicamba, linuron, metolachlor, metribuzin, oryzalin, pendimethalin, and quinclorac. Stand reductions by dicamba (a preplant and postemergence herbicide), up to 100% at 4 WAT and up to 85% at 16 WAT, were those most severe. Seeded and established buffalograss showed excellent tolerance to a few preemergence herbicides that could he used effectively and safely to control weeds during establishment and maintenance of buffalograss. Chemical names used: 2-chloro-N-(2,6.diethylphenyl)- N- (methoxymethyl) acetamide (alachlor); 6-chloro-N-ethyl-N'-(1- methylethyl)- 1,3,5-triazine-2,4-diamine(atra zine);N-butyl-N-ethyl-2,6-dinitro- 4- (trifluoromethyl)benzenamine(benefin);2[[4-chloro- 6-(ethylamino)- 1,3,5- triazin-2-yl]amino]-2-methylpropanenitrile (cyanazine); dimethyl 2,3,5,6- tetrachloro-1,4-benzenedicarboxylate (DCPA);3,6-dichloro-2- methoxybenzoic acid (dicamba);S,S-dimethyl 2-(difluoromethyl)-4-(2-methylpropyl)- 6- (trifluoromethyl)-3,5- pyridinedicarbothioate (dithiopyr);N'-(3- 4- dichlorophenyl)-N-N-dimethylurea(diuron); N-[3-(1-ethyl-1- methylpropyl)-5- isoxazolyl]-2,6-dimethoxybenzamide(isoxaben);N'-(3,4- dichlorophenyl)-N- methoxy-N-methylurea (linuron); 2-chloro-N-(2-ethyl-6- methylphenyl)-N-(2- methoxy-1-methylethyl)acetamide (metolachlor); 4-amino-6-(1,1- dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one (metribuzin); 2- [[[[(4-methoxy-6- methyl-1,3,5-triazin-2- yl)amino]carbonyl]amino]sulfonyl]benzoic acid (metsulfuron);4- (dipropylamino)-3,5-dinitrobenzenesulfonamide (oryzalin); N-(1- ethylpropyl)- 3,4-dimethyl-2,6-dinitrobenzenamine (pendimethalin); N3,N3-di- n-propyl- 2,4-dinitro-6-(trifluoromethyl)-m-phenylenediamine(prodiamine);6- chloro- N,N'-bis(1-methylethyl)-1,3,5-triazine-2,4-diamine (propazine); 2- chloro-6- [(4,6-dimethoxy-2-pyrimidinyl)thio[benzoic acid (pyrithiobac); 3,7- dichloro- 8-quinolinecarboxylic acid (quinclorac);Team(TM) [premix of 1.33% benefin and 0.67% 2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl)benzenamine] (trifluralin).
