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 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...

Asulam for tansy ragwort control in alfalfa : field efficacy and selectivity factors

Creator:: Harper, Delbert Ray
Abstract:: Tansy ragwort (Senecio jacobaea L. ) is a poisonous weed which infests alfalfa fields in western Oregon. Studies were conducted to evaluate the effectiveness of asulam (methyl sulfanilylcarbamate)for control of tansy ragwort in alfalfa and to elucidate factors responsible for its selectivity. In seven replicated field trials in 1973 and...

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...

Influence of Norbak, Dacagin, and Vistik on spray drift, volatility, adherence, and efficacy of several herbicides

Creator:: Ekins, Walter Leo
Abstract:: Norbak, Dacagin, and Vistik, when mixed with a spray solution, each have the unique property of increasing the viscosity of that solution. This property has been used commercially for the reduction of spray drift. Studies were made of the drift control adjuvants to determine the following: (1) the effect of...
