| Abstract/Contents: | "Dandelion (Taraxacum officinale) is the most easily identified broadleaf weed in lawns and possibly the most common. Many herbicides including 2,4-D do a good job controlling dandelions when applied in the fall or late spring, but even ester formulations of 2,4-D can be ineffective if applied too early in spring. The specific objectives of this study were to compare dandelion control and dandelion bloom suppression with 1) late-winter (mid-March) versus spring (late April) application timings of Defendor+Dimension (dithiopyr), 2) single versus sequential applications of Defendor+Dimension, and 3) whether or not the addition of Trimec Classic (2,4-D + MCPP + dicamba) would improve dandelion control when added to the sequential application timing. The overarching objective was to evaluate the efficacy of Defendor for dandelion control and bloom suppression. Dandelion coverage was reduced most when two applications of Defendor as part of a Dimension split application was used. Application timing in March of Defendor+Dimension successfully inhibited dandelion bloom. April applications were too late to provide dandelion flower suppression. Dandelion control from March applications with Defendor+Dimension was not improved when Trimec Classic was added to the second sequential application in April likely because little dandelion foliage was present when the Trimec Classic was applied. About 30-40% of the dandelions initially thought to be controlled by two sequential applications of Defendor+Dimension fully recovered, while others were completely controlled. If early spring broadleaf weed control is needed, Defendor is an herbicide that provides early season suppression of dandelions and keeps them from flowering." |
