Asulam in western Oregon pastures : broadleaf dock control and tolerance of important grass and legume species

Creator:: Majek, Bradley A.
Abstract:: In previous research in Europe, asulam (methyl sulfanilylcarbamate) was found to be a potentially useful herbicide for controlling broadleaf dock Rumex obtusifolius L. ) in permanent pastures. Asulam was also reported to have a low margin of safety when used on common pasture species. Field studies were conducted in western...

Germination and growth characteristics of five accessions of jointed goatgrass (Aegilops cylindrica)

Creator:: Gleichsner, Jean A.
Abstract:: Laboratory and field studies were conducted at Pendleton, Oregon, during 1983 and 1984 to evaluate germination and growth characteristics of five jointed goatgrass (Aegilops cylindrica Host) accessions collected from sites in Echo, Ione, Pendleton, Condon, and Elgin, Oregon. Spikelets were germinated for 27 days at room (23 +̲ 2 C)...

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...

Effect of a pre-irrigation period on the activity of ethofumesate applied to dry soil

Creator:: McAuliffe, David
Abstract:: Applications of ethofumesate in Oregon have been observed from previous research and from commercial use to be less effective when applied to dry soils, even if subsequent precipitation occurred within a few days. Two field studies were established in the summer of 1979 using sweet corn (Zea mays L. 'Jubilee')...

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 influencing the herbicidal activity and persistence of isomers of 1, 1-dimethyl-diisopropyl-indanyl ethyl ketone in soil

Creator:: Donaldson, Dean Robert
Abstract:: The purpose of this study was to evaluate the activity of Sindone (isomers of 1, 1-dimethyl-diisopropyl-indanyl ethyl ketone) under field conditions and to gain information regarding the rate of detoxification of Sindone in soil. A series of trials were established in sugar beet fields in California, Oregon, and Washington. Sindone...

Behavior of metribuzin and ethylmetribuzin in soil

Creator:: Peek, Daniel C.
Abstract:: The behavior of metribuzin [4-amino-6-(1,1- dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one] and ethyl-metribuzin (4-amino-6-(1,1-dimethylethyl)-3- (ethylthio)-1,2,4-triazin-5(4H)-one] in soil was studied to determine if differences in herbicide behavior in soil could explain (a) the inconsistent herbicidal activity of these chemicals and (b) the greater activity of metribuzin, as compared to ethyl-metribuzin. Metribuzin had higher activity than ethyl-metribuzin...
