| Abstract/Contents: | "Several experiments were conducted to evaluate quinclorac for broadleaf weed control during 1990 through 1992. The sites were maintained for good turfgrass growth. Applications were made with a bicycle plot sprayer utilizing 30 gallons per acre (gpa) except for the experiment comparing lawn care programs. A handgun applying 150 gpa was used in the lawn care experiment. Quinclorac was also evaluated in tank mixtures with standard postemergence broadleaf herbicides. The broadleaf weeds in these studies included common dandelion (TAROF), white clover (TRFRE), mouseear chickweed (CERVU), yellow woodsorrel (OXAST), corn speedwell (VERAR), buckhorn plantain (PLALA) and broadleaf plantain (PLAMA). Kentucky bluegrass (POAPR) and bermudagrass (CYNDA) were acceptable in tolerance to quinclorac. White clover and corn speedwell control was excellent with quinclorac at 0.375 LB ai/A. Quinclorac tank mixtures with standard broadleaf herbicides continued to provide excellent control of white clover and corn speedwell. Common dandelion control was variable with quinclorac. At 0.5 to 0.75 LB ai/A of quinclorac, dandelion control was generally good to excellent for 2 months and sometimes longer. Quinclorac at 0.375 LB ai/A provided about 1 month of control of dandelion and reinfestation occurred. Fall applications of quinclorac failed to provide control until April. A fall treatment using a tank mixture of quinclorac and 2,4-D or dicamba provided better control of dandelion than either formualtion alone. Mouseear chickweed control with quinclorac was acceptable for 1 to 2 months and reinfestation was evident. Dicamba and a tank mixture of dicamba with quinclorac provided excellent mouseear chickweed control. Quinclorac with 2,4-D was ineffective for mouseear chickweed control in these studies. Yellow woodsorrel, broadleaf plantain and buckhorn plantain control was poor with quinclorac and unacceptable in these studies. Low rates of 2,4-D plus triclopyr gave marginal broadleaf plantain control; however, a tank mixture with quinclorac at 0.75 LB ai/A provided excellent control. The tank mixture of quinclorac and triclopyr plus clopyralid was also superior to either of these formulations applied alone. Dicamba at 0.25 LB ai/A failed to control buckhorn plantain and the addition of quinclorac in a tank mixture did not improve the control. Triclopyr plus clopyralid and 2,4-D plus triclopyr gave good to excellent yellow woodsorrel control. However, the tank mixtures of these formulations with quinclorac were antagonistic showing lower levels of yellow woodsorrel control." |
