The influence of light, temperature and humidity on the herbicidal activity of bromoxynil (3,5-dibromo-4-hydroxybenzo-nitrile) on Amsinckia intermedia

Creator:: Zimmerman, Martin (Martin Joseph)
Abstract:: The use of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) to control broadleaf weeds in cereal crops has become widespread. This herbicide has not always performed satisfactorily for reasons which were not clearly evident. The effects of temperature, light and humidity on the herbicidal activity of bromoxynil on coast fiddleneck, Amsinckia intermedia, were studied. Fiddleneck...

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...

The reproduction and mode of spread of sago pondweed (Potamogeton pectinatus L.) in irrigation system

Creator:: Ogg, Alex G.
Abstract:: Nine experiments were conducted during 1964 and 1965 to study the methods of reproduction and mode of spread of sago pondweed (Potamogeton pectinatus) in irrigation systems. Frequent treatments of sago pondweed foliage with aromatic solvent greatly reduced the number of tubers in the substratum of an irrigation canal. However, complete...

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...

Effect of two methylcarbamates on the toxiciity of isopropyl m-chlorocarbanilate (chlorpropham) to safflower (Carthamus tinctorius L.) and common buckwheat (Fagopyrum esculentum Moench.)

Creator:: Kirkland, Kenneth
Abstract:: Addition of the methylcarbamate compounds p-chlorophenyl N-methylcarbamate (PPG-124) and 1-naphthyl N-methylcarbamate (carbaryl) to various herbicides has resulted in reduced rates of degradation. Carbaryl affects the degradation of certain herbicides in both plants and soils while PPG-124 has only been demonstrated to affect degradation in soils. Both these materials are effective...

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. )...

Asulam for tansy ragwort control in alfalfa : field efficacy and selectivity factors

Creator:: Harper, Delbert Ray
Abstract:: Tansy ragwort (Senecio jacobaea L. ) is a poisonous weed which infests alfalfa fields in western Oregon. Studies were conducted to evaluate the effectiveness of asulam (methyl sulfanilylcarbamate)for control of tansy ragwort in alfalfa and to elucidate factors responsible for its selectivity. In seven replicated field trials in 1973 and...
