Efficacy of PC Turf herbicide product at different application rates and volumes – Spring 2010 trial.
This study tests the efficiency of PC Turf herbicide products when applied at varying rates and volumes. The turf was separated into 10 groups, 8 of which had different strengths and rates of WW1, 1 with a general herbicide, and 1 control. The presence of weeds was rated pre-treatment during treatment and post-treatment. After initial treatment evidence on broadleaf weeds of leaf curling and necrosis. The different trial groups yielded statistically significant differences in a non-linear pattern. The broadleaf weed composed 27% of the plot pre-treatment. After 2 weeks the broadleaf population decreased to 16% and decreased to after 10 weeks where it composed 11% of the plot. Similar patterns were observed in the visual weed ratings with a slight regrowth. The conclusion was made that greater volume and concentrations of x spray resulted in significant weed control, not unlike that of the general herbicide used.
