New and revised offerings include:

Italian Ryegrass Management in Inland Pacific Northwest Dryland Cropping Systems (PNW778)

Italian ryegrass is a problem weed for grain growers in the Northwest’s high rainfall zones. This guide looks at multiple control strategies that can be combined to build an integrated management plan. Authors include Endowed Chair for Small Grains Extension and Research Drew Lyon, R. J. Cook Endowed Chair Ian Burke, University of Idaho Weed Science Principal Researcher Joan Campbell, and Oregon State University Scientist Judit Barroso.

Designated Forestland in Washington State (FS388)

Designated Forestland (DFL) is a money-saving property tax assessment option for qualifying forest landowners in the state of Washington. This publication is intended to help small forest landowners in Washington better understand DFL, including how it works, potential benefits, eligibility requirements, and more. The author is WSU Extension Forestry Professor Kevin Zobrist.

Use of Probiotics in Pacific Oyster and Manila Clam Aquaculture (FS387E)

Shellfish, like any farmed livestock, can harbor pathogens harmful to people and shellfish. Adding beneficial microorganisms to shellfish water as supplemental feed has been proven to bring health benefits and reduce disease-causing organisms. Learn about the ongoing research taking place in Oregon and Washington in this guide by WSU Cranberry and Shellfish Extension Specialist Laura Kraft, Oregon State University Professor Christopher Langdon, and Vancouver Island University’s Timothy Greene.

Revised guides

Harvest Weed Seed Control: Applications for PNW (Pacific Northwest) Wheat Production Systems (PNW730)

Herbicide resistance is of growing concern to wheat growers in the Pacific Northwest. This guide takes a regionally focused look at harvest weed seed control (HWSC), a non-chemical approach developed in Australia that takes advantage of seed retention at maturity in many dominant annual weed species. Authors include WSU Endowed Chair Drew Lyon; Professor Michael Walsh of Charles Sturt University; Oregon State University Weed Scientist Judit Barroso; and University of Idaho Weed Science Principal Researcher Joan Campbell.
