led the way in large-scale production of juneberry. Juneberry orchards have been established in Saskatchewan since the 1980s and, slightly later, in Manitoba. There are limited weed control options in juneberry orchards. Herbicides are not registered
preemergence (PRE) herbicides for summer annual weed control can compromise establishment of overseeded cool-season turfgrass species in the fall. Yelverton and McCarty (2001) reported that prodiamine reduced perennial ryegrass establishment when applied at
expensive and technically challenging practice for organic grape production ( Dufour, 2006 ; Guthman, 2000 ), and many organic farmers rely on mechanical and hand cultivation for weed control. Although these methods are highly effective, they are also labor
). Chemical weed control is essential to obtain the highest possible pumpkin yields in NT production systems, and tank mixtures of various herbicides are generally necessary to maximize weed control ( Brown and Masiunas, 2002 ; Kammler et al., 2008
management in citrus groves greatly varies depending on the type of crop, producer, location, and availability of resources. Citrus growers use a combination of mechanical, chemical, and cultural methods to control weeds. Among various methods of weed control
Producers growing squash for markets who desire the use of more naturally occurring herbicides need alternatives that effectively provide season-long weed control. Although corn gluten meal has shown promise as an early-season preemergent herbicide
the use of more naturally occurring herbicides need alternatives that effectively provide season-long weed control. Although corn gluten meal has shown promise as an early season preemergent herbicide in vegetable production, any uncontrolled weeds can
Weed management in organic production systems is an integration of cultural, mechanical, and chemical weed control components uniquely tailored for each location and crop. Chemical weed control in certified organic cropping systems allows for use of
Herbicide use is an important component of weed management in field nursery crops. No single herbicide controls all weed species. Oxyfluorfen, simazine, and isoxaben are preemergence herbicides effective against broadleaf weeds. Oryzalin, pendimethalin, and prodiamine are effective in preemergence control of grasses and some small-seeded broadleaf weeds. Metolachlor is the only herbicide currently labeled for nursery crops that is effective in preemergence nutsedge (Cyperus) control. Fluazifop-butyl, sethoxydim, and clethodim are selective postemergence herbicides used for grass control. Glyphosate, paraquat, and glufosinate are nonselective postemergence herbicides used in directed spray applications for broad-spectrum weed control. Bentazon, halosulfuron, and imazaquin are effective postemergence nutsedge herbicides. These herbicides are discussed with respect to their chemical class, mode of action, labeled rates, and current research addressing their effectiveness in nursery crops.
, has been widely used under polyethylene mulch for effective weed control in vegetable production, including bell pepper ( Duniway, 2002 ). However, because of its ozone-depleting potential, methyl bromide is being phased out from the U.S. agricultural
