Nursery container weeds response to modification of substrate pH, substrate particle size and applied nitrogen form

Creator:: Wada, Sugae
Abstract:: Experiments were conducted to determine the influence of cultural management practices on weed growth in nursery containers. Experiments 1 and 2 evaluated the effects of dolomitic lime rate and application method on substrate pH, creeping woodsorrel (Oxalis corniculata L.) establishment in containers, and growth of azalea (Rhododendron ‘Rosebud’) and pieris...

Vegetation management and its importance in reforestation

Creator:: Cleary, Brian D. and Oregon State University. Forest Research Laboratory
Abstract:: "Control of competing vegetation during establishment is one of the key links in the chain of events leading to a new plantation and, ultimately, a productive forest resource. Experience has repeatedly shown that, without adequate site preparation, reforestation efforts almost inevitably will fail. Vegetation control during the establishment period by...

Weed control with glyphosate and glufosinate in herbicide-resistant sugarbeets (Beta vulgaris L.).

Creator:: Guza, Corey J.
Abstract:: Field studies were conducted in 1998 and 1999, to evaluate glyphosate and glufosinate for control of redroot pigweed, common lambsquarters, hairy nightshade, and barnyardgrass in herbicide-resistant sugarbeets. Treatments that included two or three applications of glyphosate, regardless of rate, or glyphosate applied once in combination with BAS 656 07 H...

Maximizing efficiency of forest herbicides in the Sierra Nevada and Oregon : research background and user guide

Creator:: Fredrickson, Edward and Newton, Michael, 1932-
Abstract:: This paper comprises two major sections. In the first, tests of the influence of several application factors on efficiency of silvicultural herbicides are described for evergreen shrub, deciduous shrub, and herbaceous forest vegetation in Oregon and California. The second presents decision trees illustrating how to use the experimental results and...

Evaluating the effectiveness of commonly used herbaceous weed control regimes in a Pacific Northwest conifer plantation

Creator:: Dinger, Eric
Abstract:: Early in the establishment of Pacific Northwest conifer plantations, herbaceous weeds often decrease seedling growth through competition for soil moisture during the dry summer months. Critical period studies have reported that reductions in competitive weed cover are necessary during the initial years of establishment to avoid reductions in seedling growth....

Political economy and trade effects of invasive species regulation : the case of noxious weeds

Creator:: Min, He
Abstract:: Many non-native weed pests of food, fiber, and nursery crops pose threats to U.S. environment and agriculture. Noxious weed regulations play an important role in preventing the introduction and spread of non-native plants, thereby protecting the local biodiversity, environment and economic activities. However, these regulations could also hamper agricultural trade....
