Title: Brochure Discussing Prevalent Issues Affecting Ash Trees

Revised Statement: Guidebook on Regular Issues Faced by Ash Trees

In Iowa, an increased attention is being given to ash trees due to the potential threat of the emerald ash borer (EAB). The looming presence of this destructive pest has led homeowners, foresters, arborists, and others to scrutinise ash trees more closely.

A color-pamphlet titled SUL21, published by Iowa State University, is designed to help identify potential problems that may resemble EAB infestation. The pamphlet aims to prevent needless removal or treatment of ash trees. Electronic copies and printed copies of the SUL21 pamphlet can be found at local Iowa county extension offices and the ISU Extension On-Line Store.

The SUL21 pamphlet provides valuable information about common pests, diseases, and declines of ash trees in Iowa. However, it does not confirm any EAB infestations in the state. Since the initial discovery in 2010, no additional EAB infestations have been found in Iowa. The discovered EAB was located 2 miles south of Minnesota on an island in the Mississippi River.

The history of ash trees is one fraught with suffering from a variety of pests, diseases, and ailments. Recently, many signs and symptoms of pests and evidence of decline in ash trees are being noticed for the first time in Iowa. While these signs could potentially be indicative of EAB infestation, as of the information provided, no such infestations have been confirmed.

The January, 2011 Horticulture & Home Pest News provides more information about the emerald ash borer. For those seeking further knowledge, this resource is a valuable starting point.

It's important to note that the development of the SUL21 pamphlet is not attributed to any specific individual or group in the provided information.

In conclusion, the attention towards ash trees in Iowa is heightened due to the potential threat of EAB. The SUL21 pamphlet is a useful tool for homeowners, foresters, arborists, and others who are scrutinising ash trees with increased attention. However, as of the information provided, no EAB infestations have been found in Iowa.
