EAB Insecticides: Label Guidance for Use Limits

February 2012 - From the Minnesota Department of Agriculture - Some insecticides used to control emerald ash borer (EAB) have annual per acre use limits. The Minnesota Department of Agriculture (MDA) offers this label guidance to help applicators and others comply with label directions, meet tree treatment objectives, and minimize environmental impacts. The MDA completed a special registration review of EAB insecticides in 2011. The review concluded that insecticides commonly used to control EAB are not likely to harm human health or the environment when used according to label directions.

Ohio

Ash Replacements for Urban and Woodland Plantings

2005 - OSU Ash Alert - In developing this guide for selecting tree species to use to replace ash, it was assumed that, if not for emerald ash borer, one or more of the ash species would be suitable for the planting. Tree species included in this guide, therefore, are generally of the same size as ash and grow well on sites suitable for one or more of the native ash species. You will not, for example, find tree species in this guide that grow to a maximum height of 25 feet and which would be suitable for planting under utility power lines, as ash would not be an appropriate tree for such a planting.
