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 influence of magnesium on the toxicity of atrazine

Creator:: Brenchley, Ronald Glenn
Abstract:: Atrazine is an asymmetrical s-triazine herbicide used pre- and post emergence for weed control in many crops. Triazine herbicides have been used in the Pacific-Northwest for weed control in orchard crops. Under certain conditions where trees were grown in nutrient deficient areas, it was noted that toxic symptoms due to...

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...

A proposed mechanism for diuron-induced phytotoxicity

Creator:: Stanger, Charles Earl, 1929-
Abstract:: Previous research has shown that specific carotenoid pigments function through oxidation-reduction reactions to protect chlorophyll from photooxidation in the presence of reduced nicotinamide adenine dinucleotide phosphate (NADP). The hypothesis that diuron (3-(3, 4- d chloropheny1)-1, 1-dimethylurea) initiates phytotoxicity by inhibition of NADPH synthesis was examined. All experiments were conducted in...

The effect of soil factors on glyphosate availability in soil

Creator:: Kawate, Michael Ken
Abstract:: Glyphosate (N-(phosphonomethyl)glycine) is an effective foliar-applied herbicide with broad-spectrum activity. Greenhouse and laboratory experiments were conducted to determine the importance of soil moisture, autoclaved soil, soil type, sphagnum peat, soil pH, added phosphorus, and plant residues on crop establishment and growth when glyphosate was applied before emergence of the crop....

Competitive effects and control of weeds in winter wheat on the Anatolian Plateau, Turkey

Creator:: Tezel, Cengiz
Abstract:: Wheat is the major crop produced on the Anatolian Plateau of Turkey. Annual weeds cause large yields reductions in the wheat crop. Several formulations of 2, 4-D and mixtures of 2, 4-D and 2,4, 5-T are the only materials currently available for use in Turkey on wheat. The objective of...

Studies of napropamide decomposition on the soil surface

Creator:: Apley, Kathryn Lynne
Abstract:: Napropamide [2-(alpha-naphthoxyl)-N,N-diethylpropionamide], a preemergence herbicide, is widely used in the United States on a variety of tree fruits, nut crops, vegetables, and mint for annual grass and broadleaf weed control. When napropamide has been left on the soil surface without incorporation through irrigation or mechanical means, inconsistent results have been...

Dinitroaniline-herbicide resistance in goosegrass (Eleusine indica) : ecophysiological aspects

Creator:: Valverde, Bernal E.
Abstract:: Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from North Carolina, South Carolina, and Mississippi was analyzed in greenhouse experiments. Leaf area and biomass measurements, including root, shoot, above-ground, and total dry weights were similar among the biotypes studied....
