TEAM Leafy Spurge Releases Newest IPM Manual: Herbicide Control of Leafy Spurge

TEAM Leafy Spurge has announced publication of its third “how-to” manual on leafy spurge management, entitled Herbicide Control of Leafy Spurge. The latest manual to be published in TEAM Leafy Spurge’s integrated pest management series on leafy spurge, the 40-page Herbicide Control of Leafy Spurge can aid producers in evaluating and selecting a herbicide management plan tailored to their needs. The manual is easy to read and its small size is practical and convenient in the field.

The herbicide control manual covers the basics, including a leafy spurge summary, herbicide overviews, sprayer calibration, the economics of herbicide use, and useful integrated pest management strategies incorporating herbicides with other control tools. A unique feature of this manual is an informational chart listing common leafy spurge herbicides, their application rates, time of application, potential level of control and precautions for their use.

Herbicides continue to be a popular, but expensive, tool for controlling leafy spurge; consequently they are most frequently used to stamp out small patches and to restrict the spread of larger infestations. Herbicides have also been integrated successfully with other management techniques, including grazing and biological control. However, before using herbicides land managers must first determine which management option or combination of options is suitable economically and environmentally for tackling their leafy spurge infestation. This manual helps them make that determination.

Developed by TEAM Leafy Spurge, the manual was authored by leafy spurge herbicide expert, Dr. Rod Lym of North Dakota State University-Fargo and coauthored by Dr. Chad Prosser of Theodore Roosevelt National Park-Medora, ND; Celestine Duncan of Weed Management Services-Helena, MT; Dr. Dean Bangsund of North Dakota State University Department of Agricultural Economics-Fargo; and Dr. Gerry Anderson, Northern Plains Agricultural Research Laboratory, Sidney, MT.

“TEAM Leafy Spurge is eager to disseminate this herbicide information because of its importance to any land manager with leafy spurge infestations,” said TLS’s program director, Gerry Anderson. “It can aid the land manager in choosing an economical and an ecologically safe strategy for incorporating herbicides into their leafy spurge management plan.”

Two earlier manuals in the IPM series, Biological Control of Leafy Spurge and Multi-species Grazing and Leafy Spurge, were matched with their own informational resource CD-ROMs. This manual will follow suit with its individual resource CD, Herbicide Control of Leafy Spurge, currently under development and scheduled to become available later this winter. That CD will feature an electronic version of its namesake manual, a photo gallery, a narrated PowerPoint presentation, and other TEAM Leafy Spurge publications.

The Herbicide Control of Leafy Spurge manual, along with other products of TEAM Leafy Spurge, are available by contacting Northern Plains Agricultural Research Laboratory, P.O. Box 463, Sidney, MT 59270; 406-433-2020; fax 406-433-5038.
