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)...

Sorption and phytotoxicity of triazine herbicides in neutral and calcareous soils

Creator:: Colbert, Floyd Oral

Intra- and interspecific interference between sweet corn (Zea mays L.) and a living mulch of white clover (Trifolium repens L.)

Creator:: Fischer, Albert J.
Abstract:: Living mulches are vegetative covers that can grow in association with row crops and may prevent soil erosion and suppress weeds. Crop reduction from association with the living mulch is a frequent problem with this cultural practice. The interference between a white clover (Trifolium repens L. "New Zealand") living mulch...

Field bindweed : a growth stage indexing system and its relation to control with glyphosate

Creator:: Whitesides, Ralph E.
Resource Type:: Dissertation
Full Text:: essential in order to develop a practical system of indexing. 17 Zadoks et al. (78) have developed an

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')...

Effect of glyphosate when applied to grass and legume seeds or preemergence to bentgrass (Agrostis tenuis Sibth.)

Creator:: Salazar, Luis Carlos
Abstract:: Paraquat (1,11-dimethy1-4,4'-bipyridinium ion) and glyphosate [N (phosphonomethyl)glycine] are herbicides utilized for chemical seedbed preparation in the establishment of grass and legume seed crops. When these herbicides are applied after seeding the crop, seeds which are not protected by a layer of soil could be exposed to the herbicide. Effects of...
Resource Type:: Masters Thesis
Full Text:: preemergence activity of glyphosate. Sprankle et al. (21) found that glyphosate was adsorbed to soil in a

The influence of various surfactant-herbicide ratios in three volumes of water on the toxicity of dalapon, paraquat, and terbacil to winter oats (Avena sativa L.)

Creator:: Migchelbrink, Kenneth John
Abstract:: Several studies were conducted to determine if a more consistent predictor of phytotoxicity to winter oats could be obtained with a surfactant-herbicide ratio or a per-unit-volume concentration of surfactant, independent of volume. The herbicides tested were 2,2-dichloropropionic acid (dalapon), 1,1'-dimethyl-4, 4'-bipyridinium (paraquat), and 3-tert-butyl-5-chloro-6-methyluracil (terbacil) with the nonionic surfactant X-77...
