Abstract/Contents:"White clover is one of the most commonly found weeds in turf and persists well under mowed conditions. Common herbicides, such as dicamba or triclopyr, can be successful in controlling white clover if applied at correct timings and rates. However, little scientific research exists which specifically evaluates nitrogen fertility and irrigation management practices as a control method to reduce white clover in a turfgrass stand. Most turfgrass weed research evaluates weed control on weed species in the soil seed bank at the location where the research is conducted. Research was conducted in 2012 and 2013 to specifically evaluate white clover invasion and management under varying irrigation and nitrogen fertility regimes. Irrigation treatments were established by watering to meet 70, 90 and 110% of evapotranspiration for turf. The nitrogen rates were 0, 2.4, 4.9 and 7.3 g of nitrogen per m2. The experimental design was a split block randomized complete block with three replications. Irrigation treatment was the main plot and nitrogen rate was the sub-plot. Nitrogen fertility treatment influenced clover counts throughout each month of the growing season, with a fertilizer by year interaction 5 out of the 7 months that were evaluated each year. Clover counts were the highest for the 0 and 2.4 g nitrogen treatments while clover counts were lowest for the 4.9 and 7.3 g nitrogen treatments. Differences in turfgrass color relative to fertilizer treatment were observed in all months except August and September. Color and quality ratings were similar in that generally the 0 g nitrogen treatment had the lowest color and quality ratings and the 7.3 g nitrogen treatment had the highest ratings. Generally, irrigation treatment was not shown to have a significant effect on clover encroachment or persistence."
