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. )...

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...

Selective control of Cirsium arvense (L.) Scop. in Mentha piperita L. with 3,6-dichloropicolinic acid

Creator:: Whitesides, Ralph E.
Abstract:: A series of field experiments was conducted during 1975 and 1976 to examine peppermint tolerance and Canada, thistle response to Dowco 290 (3, 6- dichloropicolinic acid). Peppermint oil yield and Canada thistle density were considered most important in evaluating experimental results. Peppermint tolerance to Dowco 290 was studied in weed-free...

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...

Effects of lactofen herbicide on cellular uptake of glyphosate herbicide in malva parviflora L.

Creator:: Wells, Barbara Heard
Abstract:: Time-course growth chamber studies were conducted on little mallow (Malva parviflora L.) to determine whether sublethal doses of lactofen (1'-(carboethoxy)ethyl-5-[2-chloro-4-(trifluoromethyl) phenoxy]-2- nitrobenzoate) would enhance uptake of glyphosate (N'-(phosphonomethyl) glycine) by altering membrane permeability. Lactofen-induced membrane peroxidation was determined by harvesting leaf discs, measuring stress ethylene evolution, and recording increases in...

Factors affecting selective control of wild oat and downy brome in wheat by trifluralin

Creator:: Aldridge, Jack Clifton
Abstract:: Trifluralin (a, a, a - trifluoro -2, 6 -dinitro-N, N-dipropyl-ptoluidine) is effective in controlling downy brome (Bromus tectorum L.) and wild oat (Avena fatua L.) but does not severely affect the growth of wheat (Triticum aestivum L.). Studies were conducted using germination chamber and greenhouse facilities to investigate possible factors...

The response of tomatoes to atrazine as affected by magnesium and photoperiod

Creator:: Brenchley, Ronald Glenn
Abstract:: Studies were conducted to determine the nature of the interaction between atrazine (2-chloro-4-ethylamino-6-isopropylaminos- triazine) and magnesium on tomatoes. This interaction was studied under two light regimes: continuous light and a 12-hour photoperiod. Tomato plants were grown in sand cultures at three levels of magnesium fertilization. Four weeks after planting, atrazine...
