| Abstract/Contents: | "In golf and sports turfs, annual bluegrass (Poa annua L.) is among the most problematic weeds. Given its ability to rapidly germinate and aggressively establish, perennial ryegrass (Lolium perenne L.) can be most effectively overseeded into existing turfs compared to other cool-season turfgrasses. The objective of this study was to assess the effectiveness of herbicide programs designed to suppress annual bluegrass in turf overseeded with perennial ryegrass. Studies were initiated on a loam during September 2015 and 2016 on a mature stand of annual bluegrass in North Brunswick, NJ. Separate test areas were core cultivated with soil reincorporated on 3 and 7 September 2015 and 2016, respectively. Treatments consisted of 13 herbicide programs and an untreated check arranged in a randomized complete block design with four replications. Programs involved applications of glyphosate, amicarbazone, mesotrione, and ethofumesate applied during September through December 2015 and 2016 using a CO2 backpack sprayer calibrated to deliver 375 L H2O ha-1 . 'Manhattan 5 GLR' perennial ryegrass was slit-seeded at 527 kg ha-1 on 14 September 2015 and 537 kg ha-1 on 16 September 2016. Herbicide phytotoxicity (1 to 9 scale; 9=no phytotoxicity) was visually assessed during autumn 2015 and 2016. Perennial ryegrass populations were assessed during 2016 after autumn 2015 herbicide programs. Glyphosate (0.6 kg ai ha-1 ; 4 September 2015) followed by (fb) ethofumesate (2.3 kg ha-1 ; 6 October, 3 November, and 2 December 2015) resulted in the greatest perennial ryegrass populations observed in April (100%), May (99%), June (95%), and July 2016 (94%). During autumn 2015 and 2016, herbicide programs that included four or five sequential applications of mesotrione during 15 to 30 October 2015 and 21 October to 4 November 2016 resulted in severe phytotoxicity. Results from herbicide programs applied during autumn 2015 suggest that applications of ethofumesate after overseeding was the most effective herbicide strategy to establish perennial ryegrass while suppressing annual bluegrass." |
