Terbacil controls purple nutsedge in Georgia tree nursery

Purple nutsedge is widely distributed over the earth and is possibly the most troublesome weed in cultivated lands (2). It is certainly the most economically important weed in forest tree nurseries in the southeastern United States. Cultivation (6) and fumigation (1,3) of the soil have eradicated populations of nutsedge. Repeated and frequent cultivation during 1 year transformed a 10-acre field in the Georgia Forestry Commission's Morgan Memorial nursery from a field with a few areas populated with nutsedge into a densely populated 10-acre field of nutsedge. Soil fumigation in Georgia forest tree nurseries with a mixture of 1,3dichloropropene and methyl isothiocyanate (Vortex) , methyl bromide, sodium methyldithiocarbamate (Vapam), and with tetrahydro - 3,5 - dimethyl - 2H - 1,3,5 - thiadiazine - 2 - thione (Mylone) reduced, but did not eradicate, purple nutsedge infestations.
