Abstract/Contents:"White clover and common dandelion are some of the most common weeds in turf. Herbicides, such as dicamba or triclopyr, can be successful in controlling white clover and common dandelion if applied at correct timings and rates. However, with increasing societal concerns about the use of pesticides there is a growing movement to find alternative methods to control weeds in landscapes. Little scientific research exists which has specifically evaluated nitrogen fertility and irrigation management practices as an alternative method to control common weeds in turfgrass. Research was conducted in 2014 and 2015 to evaluate white clover, common dandelion, and other common turf weed species invasion and management under varying irrigation and nitrogen fertility regimes. Irrigation treatments were established by watering to meet 70, 100 and 130% of evapotranspiration for turf. Nitrogen rates used were 0, 2.4, 4.9 and 7.3 g of nitrogen per m2 applied 4 times throughout each growing season for a total of 0, 9.6, 19.6 and 29.2 g of nitrogen per m2 per year respectively. 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 and common dandelion populations throughout the growing season. White clover densities were the highest for the 0 and 2.4 g nitrogen treatments while clover densities were lowest for the 7.3 g nitrogen treatments. Treatments receiving even the lowest nitrogen fertilizer rate showed a reduction in common dandelion population when compared to unfertilized treatments. Differences in both the color and quality of the turf were observed between fertility treatments. In 2015 each sequentially higher fertility rate resulted in increased turf color and quality. Generally, irrigation treatment did not have a significant effect on clover or dandelion encroachment and/or persistence. Although the correlation between turf irrigation rates and turf color/quality ratings was largely not statistically relevant, numerical trends strongly suggest that the color and quality of the turf was reduced when irrigated at a 70% ET rate."
