Abstract/Contents:"Kurapia (Phyla nodiflora) is a low-growing, herbaceous, perennial dicot groundcover belonging to the Verbenaceae. Dense canopy and deep root system of this plant provide it with excellent drought tolerance. In general, Kurapia can survive with even less water than warm-season turfgrasses, depending on aesthetic preference, requiring irrigation once a week or less, often depending on temperature and evapotranspiration. Since the biggest weed management challenge in Kurapia is selectively controlling broadleaf weeds in a broadleaf groundcover, our goal was to test injury and regeneration rate of Kurapia caused by 2,4-D, dicamba, MCPP and MCPA both alone and in combinations. Four single active ingredient herbicides alone and in 2- or 3-way mixes were tested on mature Kurapia established in 2015. Herbicides used were: Weedar 64 (46.8% 2,4-D), Diablo (49.41% Dicamba), MCPP-p (26% MCPP) and MCPA-4 (48.58% MCPA). Treatments were based according to a 3-factor simplex-centroid design with additional interior points, in 3 replications and 2 locations: Riverside, CA and Phoenix, AZ. Plots were evaluated for flowering, visual quality and injury. Applied herbicides had a significant impact on all measured traits. Overall, maximum injury was observed 4 weeks after treatment, and greatest for mixes containing 2,4-D compared to combinations without or with a small amount of this herbicide. Based on the results, the most injurious active ingredient for Kurapia groundcover broadleaf weed management was 2,4-D and the safest were Dicamba, MCPP and MCPA both alone and in 2-way mixes."
