| Abstract/Contents: | "Microstegium vimineum [(Trin.) A. Camus], referred to as Japanese stilt grass and as annual jewgrass, is a summer annual. It has become an important weed in Virginia and other northeastern and southern states. It grows in disturbed areas, along streambanks, in forests, and other areas, and is shade tolerant. Experiments were conducted to determine the germination pattern for this weed, as well as control using selected preemergence and postemergence herbicides. Microstegium seed was planted the last week of February, 1998 at a field site in Virginia Beach. It germinated the last week of March, slightly in advance of smooth crabgrass. On April 9, Microstegium was in the cotyledon of two-leaf stage, while smooth crabgrass was only in the cotyledon stage. Onset of colder weather the second week of April apparently caused the decline in stand observed on April 16. Microstegium plants began flowering in the second week of October in Virginia Beach. A field site was treated with preemergence herbicides commonly used for crabgrass control in turf. Granular formulations of benefin, benefin plus trifluralin, and oxadiazon were used, while sprayable formulations of bensulide, dithiopyr, oryzalin, pendimethalin, prodiamine and siduron were evaluated. When Microstegium seed was planted 30 days after application, all preemergence herbicides evaluated controlled this weed over 80% based on shoot fresh weight reduction. Benefin at 3.0 lb ai/A, benefin plus trifluralin at 3.0 lb/A, dithiopyr emulsifiable concentrate at 0.5 lb/A, pendimethalin at 3.0 lb ai/A, and siduron at 10 lb/A, did not provide acceptable control. At that time, bensulide at 10.0 lb/A, oryzalin at 3.0 lb/A, oxadiazon at 3.0 lb/A, and prodiamine at 0.75 lb/A all reduced Microstegium shoot fresh weight by over 75%. For postemergence control, Microstegium was grown in 4-in pots containing pine bark. Plants were 4 inches tall with no tillers when treated. Based on shoot fresh weight reduction, fenoxaprop at 0.06 lb/A gave excellent control and MSMA at 2.0 lb/A provided approximately 75% control. Dithiopyr at 0.5 lb/A and quinclorac at 0.75 lb/A and quinclorac at 0.75 lb/A applied postemergence did not control Microstegium. Microstegium appears to germinate slightly earlier than smooth crabgrass yet flowers later. Microstegium can be controlled preemergence using available crabgrass herbicides for turf. Postemergence control can be obtained using certain crabgrass herbicides." |
