Abstract

The tolerance of bermudagrasses ‘Tifway’, ‘Tifgreen’, ‘Tifdwarf’, ‘Ormond’, and ‘Floraturf’ [Cynodon dactylon (L.) Pers.] cultivars to repeated annual applications of oxadiazon [2-tert-butyl-4-(2,4-dichloro-5-isopropoxyphenyl)-Δ2-1,3,4-oxadiazolin-5-one] and butralin [4-(1,1-dimethylethyl)-N-(1-methylpropyl)-2,6-dinitrobenzenamine] were evaluated over a 4-yr period. Oxadiazon treatments did not affect growth characteristics of these bermudagrasses. Butralin caused moderate to severe reduction in sod density. ‘Tifway’, ‘Ormond’, and ‘Floraturf’ were more tolerant to butralin than ‘Tifgreen’ and ‘Tifdwarf’.
