| Abstract/Contents: | "Pinoxaden is an ACCase inhibiting herbicide newly released for use in turf. It is labelled for crabgrass (Digitaria spp.) control in bermudagrass (Cynodon dactylon), zoysiagrass (Zoysia spp.) and St. Augustinegrass (Stenotaphrum secundatum). Research was conducted to evaluate the effects of pinoxaden application timing on crabgrass control. In greenhouse studies, a rate response screen was conducted using ten rates of pinoxaden on large crabgrass (Digitaria sanguinalis) six and ten weeks after germination (WAG). Visual injury and biomass reduction data were taken. I50 and I90 values were determined for both visual injury and biomass reduction for each application timing. Large crabgrass 6 WAG was more susceptible to pinoxaden applications than large crabgrass 10 WAG. In field studies, single and sequential (14 days after initial) applications of pinoxaden (1.56 kg ai ha-1) were made to smooth crabgrass (Digitaria ischaemum) at either an early (1-3 tiller) or late (4-7 tiller) growth stage. Percent coverage of smooth crabgrass was recorded throughout the trial. In 2018, early season applications were more effective at controlling smooth crabgrass than late season applications. Sequential applications to 4-7 tiller crabgrass were more effective in 2019 than in 2018. Single applications to 4-7 tiller smooth crabgrass provided less control. Both single and sequential pinoxaden applications provided more season long control when applied to 1-3 tiller smooth crabgrass than applications made to 4-7 tiller smooth crabgrass." |
