“…In previous research (7,12), chlorimuron and imaza quin applied POST generally provided lower control than that observed in this study, although the reported results on yellow nutsedge control with chlorimuron were variable. Pyridate controlled yellow nutsedge shoots, but regrowth occurred two to three WAT (6), similar to the results seen in the current study.…”

“…Pyridate at either rate did not affect yellow nutsedge shoot weight, whereas only the higher rate of flurtamone reduced yellow nutsedge shoot growth. In previous research, imazaquin, imazethapyr, and chlorimuron ap plied PRE controlled yellow nutspdge > 75% (7,12), which is greater control than that observed in this research. a For PRE and POST treatments, the plants were cut back to the soil line 8 WAT, and regrowth shoot dry weight was recorded 12 WAT.…”

Experiments were conducted to evaluate selective herbicides for yellow and purple nutsedge control in nursery crops. Chlorimuron at 0.03 and 0.06 kg ai ha−1suppressed yellow and purple nutsedge shoot growth either PRE or POST and did not reduce growth of barberry, Burford holly, Compacta holly, azalea, juniper, or photinia, although shoot tip chlorosis was noted in all species except Burford holly and juniper. Imazaquin at 0.25 and 0.5 kg ha−1and imazethapyr at 0.06 and 0.21 kg ha−1reduced growth of azalea. Imazethapyr also reduced growth of barberry, juniper, and photinia. Chlorimuron, imazaquin, and imazethapyr inhibited liriope and daylily growth. Pyridate applied at 1.0 and 2.0 kg ha−1POST did not control purple nutsedge. Pyridate and flurtamone applied POST did not control yellow nutsedge as effectively as chlorimuron, imazaquin, or imazethapyr. Flurtamone at 0.5 and 1.0 kg ha−1applied PRE or POST controlled purple nutsedge. Both pyridate and flurtamone visibly injured most nursery crops tested, although plants generally outgrew the damage.

“…A single tuber of yellow nutsedge is capable of producing about 7000 new tubers and 1900 new aerial shoots in one season (Tumblesome and Kommedahl, 1961). Cultivation or mechanical removal of yellow nutsedge often leads to spreading the tubers throughout the nursery and is therefore an ineffective control method (Wilcut et al, 1991). Container studies have demonstrated effective yellow nutsedge control using rates of bentazon, a benzothiadiazole, from 1.5 to 6.0 lb/ acre (1.68 to 6.72 kg•ha -1 ) (Fretz and Sheppard, 1978).…”

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.

“…Yellow and purple nutsedges are difficult weeds to control worldwide (Holm et al 1991), and cause severe economic loss in both agronomic and horticultural crops (Bingham 1977;Holm et al 1991;Keeley 1987;Stoller 1981;Tweedy et al 1975;Wilcut et al 1991). Both species were not considered to be serious weed problems until the 1960s (Bell et al 1962); however, enormous opportunities for nutsedge interference were created with the advent of selective herbicides (Keeley 1987).…”

Field studies were conducted from 1993 to 1995 to evaluate MON-12051 for turfgrass tolerance and control of yellow and purple nutsedges. The availability of herbicides for selective control of these weeds in turfgrass is limited. A sulfonylurea compound, MON-12051, has recently been developed for selective control of the nutsedges in turfgrass. When MON-12051 was applied at 0.07 to 0.14 kg ai/ha, the injury to Kentucky bluegrass, tall fescue, bermudagrass, and zoysiagrass was slight, with a maximum of 10% injury. At these rates, MON-12051 outperformed both bentazon and imazaquin in controlling yellow and purple nutsedges. Averaged over all tests 6 wk after treatment, yellow nutsedge control with MON-12051 was 83%. Control averaged 44% during the same period when treated with bentazon, whether applied once at 2.24 kg ai/ha or twice at 1.12 kg ai/ha. Purple nutsedge control averaged 96% when treated with MON-12051 in Kentucky bluegrass, while control was 42% with imazaquin applied at 0.19 and 0.43 kg ai/ha.
