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')...

Persistence of prodiamine and norflurazon herbicides in soil and their activity on alfalfa rotational crops

Creator:: Fischer, Vernon F.
Abstract:: Norflurazon [4-chloro-5-(methylamino)-2(3-(trifluoromethyl) phenyl)- 3(2H)- pyridazinone] and prodiamine (N3, N3-di-n-propy1-2,4- dinitro-6-(trifluoromethyl)-m-phenylenediamine) are two herbicides being considered for weed control in alfalfa. Rotational crops following alfalfa may be sensitive to residues of these herbicides. Studies were conducted in Oregon and Washington to examine the soil persistence and activity of these herbicides on...

The reproduction and mode of spread of sago pondweed (Potamogeton pectinatus L.) in irrigation system

Creator:: Ogg, Alex G.
Abstract:: Nine experiments were conducted during 1964 and 1965 to study the methods of reproduction and mode of spread of sago pondweed (Potamogeton pectinatus) in irrigation systems. Frequent treatments of sago pondweed foliage with aromatic solvent greatly reduced the number of tubers in the substratum of an irrigation canal. However, complete...

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...

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...

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...

An evaluation of weed interference in rice grown on hydromorphic soils in West Africa

Creator:: Diop, Amadou Makhtar
Abstract:: Field, screenhouse, and laboratory experiments were conducted to study weed interference in rice grown on hydromorphic soils at the International Institute of Tropical Agriculture (IITA) at Ibadan, Nigeria. Rice and weeds emerged at the same time, 1 week after planting. Weed dry weight was significantly reduced when the crop was...

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...
