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)...

Degradation of the herbicide EPTC in three Willamette Valley soils

Creator:: Coleman, Quentin Charles
Abstract:: EPIC (S-ethyl dipropylthiocarbamate) is a selective herbicide which controls some annual grasses, annual broadleaves, and perennial grasses when incorporated into the soil before planting. In the last few years, reports have been received of certain fields in the Willamette Valley of Oregon in which EPIC was no longer effective. Preliminary...

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. )...

Factors influencing the effectiveness of activated carbon used to protect newly-seeded grasses from herbicides

Creator:: Burr, Ronald J.
Abstract:: Previous research has shown that activated carbon is effective in inactivating certain herbicides applied as a preemergence treatment. Studies were conducted in the greenhouse to determine the influence of various factors on the ability of activated carbon to inactivate herbicides applied after carbon application. Field studies were conducted to determine...

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...

Factors influencing metribuzin use in strip-planted wheat

Creator:: Zeghida, Ali
Abstract:: Equipment for strip-till planting is under development in wheat-fallow rotations in the Columbia Basin of Oregon. This involves the absence of tillage during the fallow season. At planting time, the strip-till planter creates a narrow band into which the wheat seed is placed. The area between the rows is undisturbed...

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...

Non-herbicidal effects of dinoseb on winter wheat yields

Creator:: Valverde, Bernal E.
Abstract:: A series of experiments were conducted from 1983 to 1985 to determine the effects of dinoseb [2-(1-methylpropyl)-4,6-dinitrophenol] on winter wheat (Triticum aestivum L. em Thell) yields. Field trials on dinoseb timing and dinoseb plus supplemental pesticides were established in an effort to elucidate the possible factors involved in the yield...
