| Abstract/Contents: | "Management of purple nutsedge is difficult due to its perennial nature (vegetateive reproduction from tubers) and tolerance to most herbicides registered for use on warm-season turfgrass species. Application of herbicides which are not effective on purple nutsedge reduce competiton from other weed species and provides a niche where purple nutsedge can thrive. An important first step in devising a management strategy is to properly identify the nutsedge species present since control options vary with species. Purple nutsedege [nutsedge] can be distinguished from other species by observing overall growth habit, leaf color and shape, tuber characteristics and flower color. Purple nutsedge is generally no taller than 8 to 12 inches, has dark green leaves with boat shaped leaf tips, irregular shaped, black tubers that are bitter to the taste and purple flowers. Following recommend [recommended] cultural practices which result in healthy turf is key component of a purple nutsedge management plan. Correcting drainage problems and proper use of irrigation will also decrease the potential for purple nutsedge invasion. When vertical mowing or aerifying in a nutsedge infested area, care should be taken so that clippings or soil cores are not spread in nutsedge-free areas since nutsedge tubers could be present in this waste material. Renovation can also lead to purple nutsedge infestations. Only nutsedge-free soil and sod should be used in these operations. Few herbicide are available which provide effective control of purple nutsedge in warm-season turfgrass. Image, Manage and MSMA/DSMA can be used but repeat applications are usually necessary and tolerance varies with turfgrass species and herbicide. In general an integrated approach which utilizes proper cultural practices and sanitation to prevent or reduce purple nutsedge invasion in conjunction with judicious use of herbicides will provide the best results." |
