| Abstract/Contents: | "Dandelion (Tarazacum officinale Weber ex Wigg.) is a common weed problem in turf. Germinating seedlings are highly susceptible to the fungus Phoma macrostoma Montagne, which causes them to turn white (photobleaching) and die. The objective was to determine the least effective rate of application of this pathogen as a bioherbicide for pre-emergent control of dandelion. Phoma macrostoma was formulated as a granule for broadcast application, with 1X representing the nominal recommended application rate. It was applied at 4X, 2X, 1X, 1/2X, 1/4X, 1/8X, and 0X (nontreated control), with a mixture of grass and dandelion seeds. Trials were conducted as a RCBD with four replications at five sites in Canada and one in the USA over 2 years. Dandelion control (%) was calculated using Abbotts's transformation relative to the nontreated control. At rates greater than 1X, 100% dandelion control was attained in all trials. There was effective dandelion control (>60%) in 91% of the trials at the 1X rate and 71% of trials at the 1/2X rate. Control of dandelion seedlings lasted throughout the season. Control was ineffective (<60%) at lower rates. We conclude that a pre-emergent bioherbicide was effective at the 1X application rate to reduce the dandelion seed bank and prevent dandelion establishment." |
