Dollarspot suppression by fertility programs on creeping bentgrass fairway turf

This study was conducted to test an experimental fertilizer’s effects on dollar spot suppression in creeping bentgrass in putting green turf. 4 treatments were applied including a control group. A clear improvement in the number and size of dollar spots was observed after 2 applications of treatments including TruPrill. This was greater than one application of the Clubegreen treatment. The results of the study found that in general the treatments involving TruPrill were significantly better quality over the Clubgreen treatment and control with fewer dollar spots present in the turf. The club green treatment had greater quality than the control group at the beginning of the experiment however, the improvement disappeared by the end of the trials.
