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')...

The effect of 2,4-D on the respiration rate and ethylene production of Bartlett pears and Red Delicious apples

Creator:: Fechtig, Allen David
Abstract:: After nearly 20 years of commercial use in orchards without apparent tree injury in Oregon and Washington, 2,4-D [(2,4-dichlorophenoxy) acetic acid] was reported in 1970 to cause injury to apple and pear trees in Washington. In the early 1970's, there was widespread concern among growers, researchers, and processors in the...

The soil persistence and crop selectivity of 3, 6-dichloropicolinic acid

Creator:: Olson, David Lloyd
Abstract:: Field studies were conducted in 1973 and 1974 to determine the soil persistence of the herbicide M-3785 (containing 0.5 lb a.e. Dowco 290 + 2.0 lb a.e. 214D/gallon). under cropping situations. Spring barley (Hordeum distichon L. 'Hannchen') was grown at Corvallis, Oregon and winter wheat (Triticum aestivum L. 'Nugaines.') was...

Interaction of ethofumesate with dry soil

Creator:: McAuliffe, David
Abstract:: Previous studies have shown loss of ethofumesate activity when the herbicide was applied to dry soil (2% w/w moisture content) in both field and greenhouse studies, even when rainfall or irrigation was received within a few days. Laboratory studies were conducted to determine the mechanism for this activity loss. Dry...

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...

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...

Apoplastic distribution of atrazine and glyphosate in intact sunflower leaves

Creator:: Jachetta, John Joseph
Abstract:: Apoplastic distribution patterns of atrazine [2-chloro-4-(ethylamino)- 6-(isopropylamino)-s-triazine], glyphosate [N-(phosphonomethyl)- glycine], the naturally occurring apoplastic leaf solutes, and the apoplastic dye PTS (trisodium 3-hydroxy-5,8,10-pyrenetrisulfonate) were compared. Aliquots of sap were expressed from intact sunflower leaves in a pressure chamber over intervals of 0.2 to 0.4 bars. Three distinct fractions were detected...

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...
