The Leafy Spurge Plant

The focus of the article is the description of the plant itself, it's parts, it's stems, it's flowers, it's roots, it's seeds, it's seedlings, vegetative buds, genetic diversity and it's latex and chemical properties. It's history in North America with the citation of it's roots overseas in Spain, Russia, the Balkans, Italy and Siberia is given brief overview

Distribution and Economic Impacts of Leafy Spurge in North Dakota

The history, the distribution and the economics impacts of the weed, leafy spurge, in North Dakota, are reviewed for the reader. Leafy spurge was introduced as early as 1827 in Massachusetts. However, it did not develop into a problem under later in the Great Plains states. By 1950, this weed was found in every province of Canada, except for Newfoundland. Leafy spurge is found in all 53 counties of North Dakota. In those areas infested, the economic impacts of leafy spurge are first felt in hay and livestock productions. Next is the added costs of leafy spurge control, including chemicals and their application. The third effect is added expenditures on non-agricultural items such as roads, railroads, public utilities and government lands. The costs related to leafy spurge to the state of North Dakota averaging 1978-82 was approximately $13 million per year. The necessity of the continuance of management strategies of this weed are highlighted as being the appropriate measure to reduce future losses

Control of Leafy Spurge with Herbicides

The issue of how to control leafy spurge is problematic. the application of herbicides and a proper management control have proven the most effective treatment for top growth and root control.Herbicides that have been chosen to address this typically have been 2-4, D, dicmaba (Banvel), glyphosate (Roundup) and picloram (Tordon). This article discusses the most effective usage of herbicides for the control of leafy spurge in several different management situations. The timing of the herbicide application, the control in pasture and range lands, it's control in wooded areas, it's control for small infestations and the economics of leafy spurge control are each addressed in the article. It was summarized that if with proper well planned and implemented leafy spurge management strategies that once unproductive lands could be returned into agriculturally productive lands once again

Research Programs for Leafy Spurge Control in the United States and Canada

The topic is the weed Leafy Spurge and the issues it presents agriculture in several US states: North and South Dakota, Montana, Wyoming and Nebraska. Each state has had it's own research into the treatment of this weed. In 1978, the USDA began biological studies using insects for addressing this problem

Environmental Effects on Picloram Translocation in Leafy Spurge

Cost Effectiveness of Leafy Spurge Control During a Five-Year Management Program

The importance of leafy spurge control on long-term land values is difficult to assess, but short-term returns can be estimated by measuring changes in forage production and grazing capacity following leafy spurge control. The purpose of the five year study discussed in this article was to evaluate several herbicides for leafy spurge control, influence on forage production, and cost effectiveness

A Summary of Leafy Spurge Control with Herbicides in North Dakota since 1963

This was an overview of experiments with various herbicides on leafy spurge. These experiments suggested that it could be controlled for varying lengths of time depending on the herbicide treatment used. Eradication was not obtained with any treatment on established leafy spurge stands

Leafy Spurge Control: 10 Years of Research Enhancement

A history of the presence of the weed, leafy spurge' dating back to 1909, is given. The North Dakota Agricultural Experiment Station began conducting research on this plant in the 1920's. Enhanced funding, cultural control, chemical control, biocontrol via insects and diseases, plant physiology and basic research and public awareness are touted as essential to the control of this weed
