This study evaluates the effectiveness of elven chemical control treatments in correlation to a control to determine their effects on dollar spot disease in creeping bentgrass. Treatment was applied over an eight-week period and observed for a total of twelve weeks. Treatments that provided the best control were: Banner 130 EC (62 mL - 14 days), Daconil 2787 EC (190 mL - 14 days), Primo MAXX + Daconil 2787 (8 mL + 190 mL - 14 days), Banner MAXX (51 mL - 14 days), Primo MAXX + Banner MAXX (8 mL + 51 mL - 14 days) and BAS 51002 F (Emerald) (5.6 g - 21 days). Over the course of the study, no phytotoxic levels were detected. Further results of the study are presented in the report in table 1.
