Factors influencing wild oat control with N-benzoyl-N-(3,4-dichlorophenyl) alanine (SD 30053)

Creator:: Colbert, Donald Robert
Abstract:: Studies were conducted in 1969 and 1970 to evaluate the effectiveness of an experimental herbicide, SD 30053 (alanine, N-benzoyl-N-(3, 4-dichlorophenyl)-, ethyl ester), for wild oat (Avena fatua L.) control in winter cereals. The 1969 field studies showed that postemergence applications of SD 30053 were effective in controlling wild oats. Wild...

The effects of N-1-Naphthylphthalamic acid on growth of yellow nutsedge and its control with N-Phosphonomethyl glycine

Creator:: Paller, Enrique C.
Abstract:: Greenhouse and growth chamber experiments were conducted with the following objectives: (a) to study the effects of N-1-naphthylphthalamic acid (naptalam) on shoot and tuber production, rhizome transformation, and growth of yellow nutsedge (Cyperus esculentus L.) plants; (b) to study the effects of N-phosphonomethyl glycine (glyphosate) on nutsedge plants at different...

Intra- and interspecific interference between sweet corn (Zea mays L.) and a living mulch of white clover (Trifolium repens L.)

Creator:: Fischer, Albert J.
Abstract:: Living mulches are vegetative covers that can grow in association with row crops and may prevent soil erosion and suppress weeds. Crop reduction from association with the living mulch is a frequent problem with this cultural practice. The interference between a white clover (Trifolium repens L. "New Zealand") living mulch...

Factors influencing the effectiveness of activated carbon used to protect newly-seeded grasses from herbicides

Creator:: Burr, Ronald J.
Abstract:: Previous research has shown that activated carbon is effective in inactivating certain herbicides applied as a preemergence treatment. Studies were conducted in the greenhouse to determine the influence of various factors on the ability of activated carbon to inactivate herbicides applied after carbon application. Field studies were conducted to determine...

Interference of annual weeds in seedling alfalfa

Creator:: Fischer, Albert J.
Abstract:: The interference of barnyardgrass (Echinochloa crusgalli), pigweed (Amaranthus retroflexus),downy brome (Bromus tectorum),and tumble mustard (Sisymbrium altissimum) with alfalfa was studied. Alfalfa was seeded with each of the four weeds on August 14 and September 15, 1981, and on April 13, 1982. Alfalfa also was seeded on August 27, 1981, with...

Sethoxydim herbicide in red fescue and bentgrass : levels and mechanisms of selectivity

Creator:: Butler, J. Hugh B.
Abstract:: The herbicide rate required to reduce growth by 50% (GR₅₀) of 11 cultivars of red fesue (Festuca rubra L. and F. rubra ssp. commutata) and for four cultivars of bentgrass (Agrostis tenuis Sibth. and A. stolonifera L. var. palustris) to sethoxydim (2-[1-(ethoxyimino) butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one) was determined in greenhouse and laboratory experiments....

Influence of weed density on efficacy of two soil-applied herbicides

Creator:: Burrill, L. C.
Abstract:: Several studies were conducted to determine the effect of weed density on herbicide efficacy. Diuron [3-(3, 4- dichlorophenyl) -1, 1- dimethylurea] was tested on various densities of Italian ryegrass (Lolium multiflorum Lam. ) under greenhouse and field conditions. Cycloate (S-ethyl N-ethylthiocyclohexanecarbamate) was tested on green foxtail (Setaria viridis (L. )...

Factors influencing barnyardgrass (Echinochloa crus-galli) control with diclofop

Creator:: West, Lynn Douglas
Abstract:: Diclofop (2- [4 -(2, 4-dichlorophenoxy)phenoxy] propanoic acid), formulated as the methyl ester, selectively kills barnyardgrass [Echinochloa crus -galli (L.) Beauv.] in several crops when applied postemergence. Studies were conducted to determine the effect of soil moisture, barnyardgrass age, and site of exposure on control of barnyardgrass with diclofop. Soil moisture...
