Dollar Spot Expression
Background Information:
The effects of fertility on dollar spot expression; 2009 Laval research station
Mineral Builder + Daconil provided the best quality readings and the least incidence of dollar spot disease. Mineral Builder without Daconil was significantly better than the control. Mineral Builder plus foliars was slightly better than mineral builder alone. The effects of nitrogen on dollar spot expression have been well documented. Nitrogen has been used as a tool to “grow out” lesions by improving the plants tolerance to infection. To further reduce the effect of dollar spot, we need to review the plants ability to utilize its natural defense mechanisms. This process is known as plant resistance. The objective of this research project was to determine the effects of the sponsor's fertilizer programs on dollar spot disease and general performance of creeping bentgrass putting green turf maintained at fairway height. Data collected included the duration and strength of the color response following application(s) of the tested products, turf quality, uniformity, and density, and resistance of the turf to disease and drought stress.
