Abstract
Tank mixtures of herbicides for control of emerged winter weeds and preemergence control of large crabgrass [ Digitaria sanguinalis (L.) Scop. # DIGSA] were evaluated on bermudagrass [ Cynodon dactylon (L.) Pers. ‘Common’ # CYNDA] fairways over a 2-yr period. Glyphosate [ N- (phosphonomethyl)glycine] applied at 0.28 kg ai/ha in tank mixtures with DCPA (dimethyl tetrachloroterephthate) at 11 kg ai/ha controlled a higher percentage of parsley-piert ( Alchemilla microcarpa Boiss. Reut. # APHMI) than either herbicide alone. When applied for spur weed ( Soliva spp.) control, DCPA was antagonistic in the tank mixture with simazine [2-chloro-4,6-bis(ethylamino)- s -txiazine]. During one yr of the 2-yr study period, control of large crabgrass was less in plots treated with combination of DCPA and glyphosate than in plots treated with DCPA alone. Less large crabgrass control was obtained in plots treated with bensulide [ O,O -diisopropyl phosphorodithioate S -ester with N -(2-mercaptoethyl)benzenesulfonamide] at 11 kg ai/ha in combinations with either paraquat (1,1′-dimethyl-4,4′-bipyridinium ion) or 2,4-D [(2,4-dichlorophenoxy)acetic acid] plus mecoprop {2-[(4-chloro- o -tolyl)oxy]propionic acid} plus dicamba (3,6-dichloro- o -anisic acid) than when treated only with bensulide.
