for weed control efficacy in turfgrass and ornamentals ( Armel et al., 2009 ; Brosnan et al., 2010 ). Mesotrione is currently registered for weed control in turf ( Anonymous, 2009b ) and has been shown to injure common bermudagrass [ Cynodon dactylon

Leachates of living Cynodon dactylon (L.) Pers. and Amaranthus sp. were applied to Carya illinoinensis (Wangenh.) C. Koch. seedlings to compare effects on growth and elemental absorption. Water applied to the weed pot or control pot (no weeds present) leached through the pot and into a funnel with a tube attached, then directly into the corresponding pecan seedling pot. After 4 months of growth, pecan seedlings receiving weed leachates had less leaf area and were shorter than those watered through control pots. These results suggest that leachates from these two weed species inhibit pecan growth, independent of any competition effects.

Within the Cynodon genus, there are nine species ( Harlan et al., 1970a ). Two Cynodon taxa, C. dactylon (L.) Pers. var. dactylon and C. transvaalensis Burtt-Davy, are important to the turfgrass industry. Tetraploid (2n = 4x = 36) C

Bermudagrass is a warm-season grass used as turf for home lawns, public parks, golf courses, sports fields, and for forage and soil conservation ( Zhang et al., 1999 ). Common bermudagrass [ Cynodon dactylon (2n = 4x = 36)] was first introduced
