Details of this species in Texas
Source: Warren & Coble 1999
Species Notes for this Location:
Purple nutsedge and yellow nutsedge are the most troublesome weeds of vegetable crops in Alabama, Georgia, Mississippi, Tennessee, and Texas (Webster 2002, Webster and MacDonald 2001, in Webster 2005b).
Management Notes for this Location:
Agricultural: Herbicides have benefitted the Cyperus species by eliminating interspecific weed competition (Keeley 1987, Webster and Coble 1997b, in Warren & Coble 1999). Purple and yellow nutsedge infestations continue to increase in many Texas peanut fields due to the use of dinitroaniline herbicides, which control most grass and small-seeded broadleaf weeds but have no effect on either nutsedge species (Grichar et al. 1992, Grichar and Nester 1997, in Warren & Coble 1999).
