Abstract

Root growth of three zoysia ( Zoysia spp. ‘Emerald’, ‘Meyer’, and ‘Matrella’) cultivars and four bermudagrasses [ Cynodon dactylon (L.) Pers. ‘Tifway’, ‘Tifgreen’, ‘Tifdwarf’, and ‘Ormond’] was determined after several consecutive annual herbicide treatments. Napropamide [2-(α-naphthoxy)- N,N -diethylpropionamide] reduced the root growth of all zoysia and bermudagrass cultivars. Prosulfalin { N -[[4-(dipropylamino)-3,5-dinitrophenyl] sulfonyl]- S,S -dimethylsulfilimine} retarded root growth of Tifgreen and Tifdwarf bermudagrass when treated at any rate. Tifway and Ormond bermudagrass and zoysia cultivars were retarded at the 3X rate (10.2 kg/ha). Zoysia grass roots were not affected by oxadiazon [2- tert -butyl-4-(2,4-dichloro-5-isopropoxyphenyl)-δ 2 -1,3,4-oxadiazolin-5-one], bensulide [ O,O -diisopropyl phosphorodithioate S -ester with N -(2-mercaptoethyl)benzenesulfonamide], or benefin ( N -butyl- N -ethyl-α,α,α-trifluoro-2,6-dinitro- p -toluidine) treatments. DCPA (dimethyl tetrachloroterephthalate) and oxadiazon did not reduce root growth of bermudagrasses, except when Tifgreen was treated with oxadiazon at 3X rate (13.4 kg/ha).
