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...

Influence of Norbak, Dacagin, and Vistik on spray drift, volatility, adherence, and efficacy of several herbicides

Creator:: Ekins, Walter Leo
Abstract:: Norbak, Dacagin, and Vistik, when mixed with a spray solution, each have the unique property of increasing the viscosity of that solution. This property has been used commercially for the reduction of spray drift. Studies were made of the drift control adjuvants to determine the following: (1) the effect of...

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...

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 lateral movement of cycloate as affected by three soil types and four methods of irrigation when applied to the soil by injection incorporation

Creator:: Stanger, Charles Earl, 1929-
Abstract:: Lateral diffusion of S-ethyl N-ethylthiocyclohexanecarbamate (cycloate)¹ is essential for satisfactory weed control with injection type incorporation in sugar beet (Beta vulgaris Linn.) production. Previous field experience with injection incorporation has indicated that sufficient lateral diffusion for satisfactory weed control has not occurred under all field conditions. Researchers who have been...

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...

Foliar vs. root uptake of the herbicide Hoe 23408 in Italian ryegrass and wild oats

Creator:: West, Geralyn Marie
Abstract:: HOE 23408 [methyl 2-[ 4-( 2, 4- dichlorophenoxy )phenoxy]propanoate] is a herbicide used to selectively-control Italian ryegrass (Lolium muitiflorum Lam.) and wild oats (Avena fatua L.) in wheat. The objective of this research was to compare the relative importance of foliar and root uptake of the herbicide in these two...

Foliage applications of terbacil to peppermint (Mentha piperita) and several weed species

Creator:: Radosevich, Steven R.
Abstract:: Several studies were conducted to determine the feasibility of using terbacil (3-tert-butyl-5-chloro-6-methyluracil) postemergence to weeds and peppermint (Mentha piperita L.). Three nonionic surfactants, four nonphytotoxic oils, and a liquid fertilizer were each combined with 0.5 lb ai/A terbacil in 35 gallons of water per acre. Weed species tested include: redroot...
