Diclofop-methyl [me yl 2-(4-(2,4-dichlorophenoxy) phenoxy) propanoate] hydrolysis, degradation, and leaching were studied in field and laboratory experiments. Greater than 75% of the applied diclofop-methyl hydrolyzed to diclofop in 2 days at 4°C, the prevailing soil temperature during western Oregon winters. Degradation beyond the diclofop molecule, also an active herbicide, was...
Large-scale safety-net programs such as Temporary Assistance for Needy Families (TANF) and the Supplemental Nutrition Assistance Program (SNAP) have been shown to alleviate the negative effects of low-wage jobs and unemployment on poor American households. However, less is known about the role of “emergency” safety net programs, such as rental...
The semi-arid dryland wheat-producing areas of the Pacific Northwest are characterized by cool, moist winters and dry, hot summers. The amount of annual precipitation is generally quite variable and inadequate for annual cropping. Where soil depth is adequate, the predominant loessal soils generally supply sufficient moisture for small grain production...
Giant hills may be classified as semi-giant, giant, or super-giant
depending on the degree of the variation. All are large,
vigorous, profusely flowering plants with characteristically poor
tuber shape, although some giant hills may have smooth tubers.
Thirteen of the fifteen Russet Burbank giant hill selections grown
in Con/all is,...
Twenty Russet Burbank seed lots were collected from
four states and one Canadian Province in 1988 and planted in
replicated trails at Powell Butte and Hermiston, Oregon as
part of a two year study to quantify clonal differences in
the cultivar. Samples of each seed lot were concurrently
increased and...
These studies compared giant hill strains of Russet Norkotah and Umatilla Russet to the parent varieties. Selections were initially based on late maturity and increased vine vigor. Subsequent evaluations emphasized yield and quality parameters in comparison to the parent varieties. Giant hills were collected from the Columbia Basin and Central...
Four experiments were conducted to evaluate the effects of
growth-promoting treatments on potato sprouts and plantlets grown in
vitro, and to determine the relationships between growth rate and
eradication of PVX and PVS through shoot-tip culture.
The approach consisted of exposing plant material to potential
growth-regulating treatments, selecting the more...
