“…Postemergence application of diclofop and linuron was more phytotoxic on the crops which is similar to the results reported by LEE (1975) and DURUTHAN (1976). They reported that most herbicides when applied as postemergence are generally phytotoxic.…”

Annual rye grass {Lolium multiflorum Lam.) is a serious and wide spread problem in cereal crops. A field experiment with a promising herbicide diclofop [(±)-2-[4-(2,4-dichlorophenoxy)phenoxy] propanoic acid] at 0.56, 0.84 and 1.12 kg ai/ha, in comparison to commonly used linuron [N'-(3,4-dichlorophenyl)-Nmethoxy-N-methylurea] at 0.84, 1.12 and 1.41 kg ai/ha was conducted to "control rye grass {Lolium multiflorum Lam.) in triticale (X Triticosecale Wittmack), wheat {Triticum aestivum L.) and rye {Secale cereale L.). The herbicides were applied as soil-incorporated, preemergence and post-emergence. Results showed that diclofop is less phytotoxic than Linuron and the postemergence application of these herbicides was more phytotoxic on all cereal crops. Diclofop applied at 1.12 kg/ha, gave almost 100 percent rye grass control and produced 45 and 115 kg/ha higher grain yields in pre-and postemergence methods, respectively, as compared to the soil-incorporated method.

“…Considerable reduction in seed yield potential may have occurred because of the late application date. In other trials, ryegrass seed yield increases associated with wild oat control have ranged from 13-82% (Barber 1976;Evans et al 1976;Lee 1975).…”

Fenoxaprop P-ethyl, a wild oat herbicide was applied to five grass species. Perennial ryegrass was tolerant to 37 g/ha, but there was a trend for a reduction in seed yield at 75 g/ha. Two Bromus species had good tolerance, but Phalaris aquatica seed yields were reduced by 80%. In a second trial, there was no significant effect on seed yield of perennial and hybrid ryegrass to fenoxaprop applied at 56 g/ha. However, there was a trend for 75 g/ha to reduce seed yield in perennial ryegrass. In a perennial ryegrass seed crop, wild oats were very competitive, reducing seed yields from 2600 kg/ha (best herbicide treatment) to 660 kg/ha in the untreated control. Excellent wild oat control was achieved with fenoxaprop at rates of 45 g/ha in August and 56 g/ha in September.

“…Establishment of warm-season grasses is often hindered by weed competi tion during early seedling growth. Heavy weed infestation during early growth can reduce forage yields or cause complete stand failure (10,21,22,23,24). Presently, herbicides available for use at seeding of warm-and coolseason grasses are limited.…”

“…Atrazine [6-chloro-A'-ethyl-N' -(1 -methylethyl) -1,3,5 -triazine -2,4 -diamine] has been used during seeding of switchgrass (18,23) and big bluestem (23). Selective control of wild oats (Avena fatua L. # 3 AVE FA) in seedings of Kentucky bluegrass (Poa pratensis L.) and perennial ryegrass (Lolium perenne L.) was achieved using MSMA (monosodium salt of methylarsonic acid) (22). Weeds were selectively controlled in bermudagrass [Cynodon dactylon (L.) Pers.]…”

Field studies were conducted for 3 yr near Mead, NE, to evaluate the effectiveness of seed safeners CGA-92194 [N-(1,3-dioxalon-2-yl-methoxy)iminobenzeneacetonitrile], NA (1,8-naphthalic anhydride), and R-29148 (2,2-dimethyl-5-methyldichloroacetyloxazolidine) to reduce herbicide injury to big bluestem (Andropogon gerardiiVitman), indiangrass[Sorghastrum nutans(L.) Nash], intermediate wheatgrass[Agropyron intermedium(Host.) Beauv.], sideoats grama[Bouteloua curtipendula(Michx.) Torr.], and switchgrass (Panicum virgatumL.) from preplant-incorporated butylate [5-ethyl bis-(2-methylpropyl)carbamothioate] and metolachlor [2-chloro-N- (2-ethyl-6-methylphenyl) -N- (2-methoxy-l-methylethyl)acetamide], applied at 4.5 and 2.2 kg ai/ha, respectively. Big bluestem stands were satisfactory, regardless of herbicide or safener treatment, although stands were reduced by NA treatment with either herbicide. Indiangrass stands varied by year, with protection from both herbicides by R-29148 in 1984 and by NA in 1985. All safeners reduced injury to intermediate wheatgrass from metolachlor and to a lesser extent from butylate; acceptable stands were obtained with metolachlor treatment when unsafened. Sideoats grama was nearly eliminated with either herbicide, regardless of safener. Switchgrass treated with NA produced stands two- to threefold higher than other safened or unsafened seed in metolachlor plots and equal to unsafened seed in the weeded control plots.
