| Abstract/Contents: | "Common lespedeza is problematic annual weed in lawns and postemergence herbicides often provide erratic levels of control. The objective of this research was to evaluate efficacy of preemergence herbicides for common lespedeza and smooth crabgrass control in a bermudagrass lawn. Treatments included single and sequential treatments of dithiopyr at 420 or 560 g ai/ha and sequential treatments of indaziflam at 34 or 53 g ai/ha at preemergence crabgrass timings, and single treatments of indaziflam at 53 or 60 g ai/ha. Initial applications of sequential treatments were applied at preemergence crabgrass timings while single treatments were applied later in spring. In 2011, all dithiopyr treatments provided excellent control (>90%) of common lespedeza but control from indaziflam was poor (<70%) at 6 months after initial treatments (MAIT). Both dithiopyr rates and indaziflam at 53 g ai/ha applied sequentially provided excellent control of smooth crabgrass but delayed applications of both herbicides provided poor control. In 2012, sequential dithiopyr applications provided good (80 to 89%) to excellent control of common lespedeza and smooth crabgrass but applications later in spring were inconsistent. Sequential indaziflam applications provided poor lespedeza control but controlled crabgrass >95%." |
