Title: Pamphlet Highlights Prevalent Issues Facing Ash Trees

A color-pamphlet titled SUL21 is available from Iowa State University, providing valuable information for homeowners, foresters, arborists, and others about common pests, diseases, and declines of ash trees in Iowa. The author of this comprehensive guide is Michael J. Raupp.

The SUL21 pamphlet serves a crucial purpose, aiming to help identify problems that may resemble emerald ash borer infestation. As the emerald ash borer is a significant threat to ash trees in North America, the pamphlet's preventive measures are particularly relevant. However, it is noteworthy that as of the current information, there are no known emerald ash borer infestations in Iowa.

The emerald ash borer was first discovered outside of its native range in North America in 2002. Since then, it has spread across many states, but as of 2010, it has not been found in Iowa. The last known detection was on a Mississippi River island south of Minnesota in 2010. Since then, no additional infestations have been reported in Iowa.

The SUL21 pamphlet is a response to increased attention to ash trees due to the looming threat of emerald ash borer. It aims to prevent needless removal or treatment of ash trees, offering guidance on identifying potential issues that may mimic emerald ash borer infestation. However, it does not address actual infestations in Iowa.

Printed copies of the SUL21 pamphlet are available at local Iowa county extension offices and through the ISU Extension On-Line Store. Electronic copies can also be found online. For those seeking further information about the emerald ash borer, the January, 2011 Horticulture & Home Pest News may provide additional insights.

It is important to remember that while the SUL21 pamphlet offers valuable guidance, it does not guarantee the absence of emerald ash borer in Iowa. Ash trees have a history of suffering from a variety of pests, diseases, and ailments, and homeowners are encouraged to keep a watchful eye on their ash trees for any signs of decline.

In conclusion, the SUL21 pamphlet is a valuable resource for anyone concerned about the health of ash trees in Iowa. By helping to identify potential problems, it aims to prevent unnecessary tree removal or treatment. While there are no known emerald ash borer infestations in Iowa at present, vigilance remains key in protecting these valuable trees.
