2024 Michigan Hop Management Guide now available
Print
EmailUpdated management reference available for Michigan hop growers through Michigan State University Extension.
In an effort to assist hop growers in making pesticide and nutrient management decisions, an updated “Michigan Hop Management Guide” has been completed and is available for free at the Michigan State University Extension Hops page. The guide includes an updated list of registered pesticides, nutrient management recommendations and a guide to seasonal pest occurrence and management activities.
Endangered Species Act impacting pesticide labels
The U.S. Environmental Protection Agency (EPA) is changing the way it enforces the Endangered Species Act in respect to pesticide applications. Growers must carefully read all pesticide labels and should look for changes in the ‘Environmental Hazards’ section, which may now require growers to check the Bulletins Live! Two system to determine if there are any new pesticide use limitation on their farm. These EPA bulletins define geographically specific pesticide use limitations for the protection of threatened and endangered species and their designated critical habitat. If your pesticide label directs you to this website, you are required to follow the pesticide use limitation(s) found on your label and in the Bulletins Live! Two system for your intended application area, pesticide product and application month. You may not see any geographically specific use limitations for the product you are applying even if your label directed you to this website. Growers should keep a copy of the bulletin with their pesticide records.
Learn more by visiting Bulletins Live! Two and contact the Michigan Department of Agriculture and Rural Development with questions at MDA-Info@Michigan.gov.
Exporter note
The U.S. Hop Industry Plant Protection Committee has actively sought harmonization of pesticide regulatory standards (maximum residue levels or MRLs) in key customer countries for the past three decades. As U.S. hops are exported worldwide, ensuring consistent regulatory standards between the U.S. and export customers avoids trade issues and interruption of shipments. Some countries do not allow application of certain plant protection products or have lower MRLs than in the U.S. If you export hops, you will need to comply with international MRLs.
Export restrictions apply to pesticides included in this guide. Growers planning to export their hops should carefully and often review the Hop MRL Tracking Chart and contact info@usahops.org for more assistance.
