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 herbicide HOE 23408; soil persistence, spring wheat cultivar tolerance, and interaction with broadleaf herbicides

Creator:: Ivackovich, Branislav D.
Abstract:: HOE 23408 [ 4-(2' , 4'-dichlorophenoxy)-phenoxy-u-propionic methylester.1 is a promising new compound for control of wild oats and other grass weeds in small grains. Several factors influencing its use for this purpose were investigated. Greenhouse bioassay studies were conducted in 1975 to determine relative persistence of HOE 23408 in four...

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...

The response of tomatoes to atrazine as affected by magnesium and photoperiod

Creator:: Brenchley, Ronald Glenn
Abstract:: Studies were conducted to determine the nature of the interaction between atrazine (2-chloro-4-ethylamino-6-isopropylaminos- triazine) and magnesium on tomatoes. This interaction was studied under two light regimes: continuous light and a 12-hour photoperiod. Tomato plants were grown in sand cultures at three levels of magnesium fertilization. Four weeks after planting, atrazine...

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...

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...

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...

Influence of lime on Italian ryegrass control in winter wheat with five herbicides

Creator:: Ozdilek, Engin
Abstract:: Liming has been shown to increase the activity of certain soil-applied herbicides. One research worker reported improved weed control with diuron after lime had increased soil pH levels. This could be caused by improved competitive ability of the wheat, greater availability of the herbicide, or a combination of the two...

Biology and control of tuber oatgrass (Arrhenatherum elatius (L.) presl. var. Bulbosum (willd.) spenn.)

Creator:: Tanphiphat, Karin
Abstract:: Tuber oatgrass (Arrhenatherum elatius (L.) Presl. var. bulbosum (Willd.) Spenn.) is a perennial grass that often becomes a weed problem in Western Oregon. Control efforts using glyphosate often give unsatisfactory results. The effects of several factors on development of tuber oatgrass were investigated. Long days and cool temperatures (16/8h, 20/10C...
