ECONOMIC ANALYSIS OF CONTROLLING LEAFY SPURGE WITH SHEEP AgEcon
Bangsund, Dean A.; Nudell, Daniel J.; Sell, Randall S.; Leistritz, F. Larry.
Leafy spurge (Euphorbia esula L.), a widely established exotic, noxious, perennial weed, is a major threat to rangeland and wildland in the Upper Great Plains. Chemical, biological, and cultural control methods have limitations in their applicability and effectiveness in treating leafy spurge. However, many of the constraints prohibiting the use of herbicides, tillage, and biological controls do not apply to sheep grazing. Sheep grazing, while known to be effective in controlling leafy spurge since the 1930s, has lacked widespread adoption as a leafy spurge control. A deterministic, bioeconomic model, incorporating relationships between sheep grazing and leafy spurge control, grass recovery, and forage use by cattle, was developed to evaluate the...

FEASIBILITY OF A SHEEP COOPERATIVE FOR GRAZING LEAFY SPURGE AgEcon
Sell, Randall S.; Nudell, Daniel J.; Bangsund, Dean A.; Leistritz, F. Larry; Faller, Timothy.
This report presents an economic feasibility study of a 5,000 head, cooperatively owned, sheep operation for leafy spurge control. The objectives were 1) determine the return on investment of the cooperative, 2) determine the proposed structure of the cooperative, and 3) ascertain the amount of capital investment required by members in the cooperative. Three sheep flock management alternatives were initially considered for the cooperative. These were 1) winter lambing, 2) spring lambing, and 3) fall lambing. The fall lambing scenario was determined to be infeasible because of logistics associated with gathering and transportation of pregnant ewes and lack of grazing pressure on leafy spurge throughout the grazing season. The total capital investment...

การใช้สารกำจัดวัชพืชกลูโฟซิเนทในข้าวโพดหวาน Thai Agricultural
Sodsai Changsaluk; Tosapon Pornprom; Naroon Waramitr; Rungsit Suwanmonkha.
Experiment on post-emergence herbicide, glufosinate in sweet corn production field conducted at the National Corn and Sorghum Research Center during November 2008-January 2010. The objective of this experiment was to study on the efficiency of herbicides and their affect on sweet corn hybrid, Insee 2 variety. The experiment laid out in RCBD, composed of 10 treatments, with 3 replications. The results revealed that weed found in the experiment were purple nutsedge (Cyperus rotundus), wild poinsettia (Euphorbia heterophylla), tropical spiderwort (Commelina benghalensis) and Itchgrass (Rottboellia cochinchinensis). The application of glufosinate at the rate of 800-1,400 g/rai, as post-emergence herbicide gave good weed control of 80-86 percent, and better...
