e0“Field studies were conducted to determine the feasibility of using imazethapyr applied preemergence (PRE) and postemergence (POST) for weed control in sericea lespedeza”
e1“Regardless of rate, yellow nutsedge and cutleaf groundcherry control at 2 mo after treatment, as determined by weed foliage biomass relative to the nontreated plants, was 90 and 80%, respectively”
e6“In the POST experiment, imazethapyr was applied at 0, 71, 142, and 213 g ai/ha to mature, recently mowed stands of sericea lespedeza”

Other claims from this paper (10)
- Intervention effect Postemergence imazethapyr gave 80% control of cutleaf groundcherry relative to nontreated plants at 2 months after treatment.
- Intervention effect Preemergence imazethapyr at 71 g/ha gave at least 78% control of large crabgrass in sericea lespedeza.
- Intervention effect Preemergence imazethapyr at 71 g/ha gave at least 78% control of stinkgrass in sericea lespedeza.
- Intervention effect Preemergence imazethapyr at 71 g/ha gave at least 78% control of yellow nutsedge in sericea lespedeza.
- Intervention effect Preemergence imazethapyr at 71 g/ha gave at least 78% control of sicklepod in sericea lespedeza.
- Intervention effect Preemergence imazethapyr at 71 g/ha gave at least 78% control of cutleaf groundcherry in sericea lespedeza.
- Intervention effect Postemergence imazethapyr at 213 g/ha did not reduce sericea lespedeza forage yield when weeds were removed.
- Intervention effect Preemergence imazethapyr at 71 g/ha gave maximum sericea lespedeza performance.
- Recommendation Imazethapyr can be used for either preemergence or postemergence weed control in sericea lespedeza.
- Intervention effect The margin of safety was greater with postemergence imazethapyr applied to mature stands than with preemergence applications to germinating seeds.
