The Emerald Ash Borer First Detectors program is part of the federal “National Plant Diagnostic Network (NPDN) First Detector program that promotes the early detection of invasive, exotic plant pathogens, arthropods, nematodes and weeds.” The EAB First Detector program is designed to help identify the first incidence of EAB in Minnesota. This first in the United States program is a joint project between University of Minnesota Extension, Minnesota Department of Agriculture, and the Minnesota Department of Natural Resources. The EAB First Detector program targeted participants with either a working or volunteer background in forest or tree care. EAB First Detector trainings were held in six statewide full-day training sessions in 2008. A modified version of this program, which now includes additional forest pests, of concern (Gypsy Moth, Asian Longhorned Beetle, and Sirex wood wasp), was held 5 times in 2009. A total of 233 volunteers committed to become First Detectors. These trained individuals scattered throughout the state will improve our scouting abilities in identifying pests and infestations early so management practices can be implemented quickly.Item Grape Insect Pests of the Home Garden, M1236(2008) Hahn, Jeffrey D.; Wold-Burkness, SuzanneGrowing grapes is becoming increasingly popular for the home gardener. Once grapevines are established, they can be productive for over 40 years. The productivity of the grapevines relies heavily on the careful choices of the home gardener. Home fruit gardeners can be successful if they select the right cultivars, properly prune grapevines annually, and maintain good fertility and pest management programs. Accurate insect identification is essential in any pest management program. In this publication we have compiled a list of insects commonly found on grapes in Minnesota. Please remember that careful, timely inspection of grapes and good cultural practices will aid in reducing the need for insecticide applications.Item Insect and Mite Galls(University of Minnesota, Minnesota Extension Service, 1996) Wawrzynski, Robert P.; Hahn, Jeffrey D.; Ascerno, Mark E.Item Insect and Mite Galls in the Landscape(University of Minnesota, Minnesota Extension Service, 1996) Wawrzynski, Robert P.; Hahn, Jeffrey D.; Ascemo, Mark E.Item Insecticide suggestions to control tree and shrub insects (Revised 1992)(University of Minnesota.

Many apple growers reduce their use of pesticides, while still harvesting quality fruit, through a set of practices known as Integrated Pest Management (IPM). IPM includes a combination of pest management techniques including monitoring for pest problems, removing diseased or infested plant material from the area, and many other cultural control techniques. Pesticide sprays are used in IPM only when necessary, and gardeners may choose from conventional or organic spray options.Item Pest management for the home strawberry patch(2015) Foord, Karl; Hahn, Jeffrey D.; Grabowski, MichelleMinnesotans who grow strawberries at home may have to combat insect pests or diseases to produce a good crop. Previous pest control strategies seeking to eliminate all pests from a garden have been shown to be unsuccessful. Today's approach combines many management methods into an integrated whole, thus the name Integrated Pest Management (IPM). IPM practices have enabled growers to place an emphasis on non-chemical methods while using pesticides secondarily or as a supplement to these methods while still harvesting quality fruit. The philosophy of IPM is to seek a balance maximizing yield while reducing human and environmental risk. This follows a particular hierarchy that begins with the best practices in cultural management.Item Potentially Dangerous Spiders(St. Paul, MN: University of Minnesota Extension Service, 1997) Pellitteri, Phil; Lewis, Donald; Hahn, Jeffrey D.Explains the benefits of spiders in nature, and cautions against spider bites.
