• (2023) How to control household ants?
• (2022) Stink bugs and boxelder bugs everywhere?
• (2022) The Economic Impact of Onion Pests in the Treasure Valley A look at pest data for onions grown in the Treasure Valley demonstrates the yield and economic impacts of specific pests and management practices. This data can help researchers, crop consultants and those interested in integrated pest management balance the costs and benefits of specific growing practices.
• (2021) Was this spider silk or something else?
• (2021) Is this a hobo spider?
• (2020) What is this huge larvae in my mason bee box?
• (2015) Integrating Integrated Pest Management Insects, weeds and plant pathogens are problems that confront farmers in trying to grow a successful crop. Insect pests can defoliate crop plants. Weeds can outcompete crops for light, water and nutrients. Pathogens can cause disease epidemics that destroy entire crops.
• (2022) Onion cost of production in Eastern Oregon and Idaho These enterprise budget resources cover the costs associated with producing onions in the Treasure Valley. The PDF document covers how costs were estimated and the Excel workbook allows you to adjust costs to better match your operation. 
• (2019) An Integrated Pest Management Strategic Plan for Treasure Valley Onions: Oregon and Idaho (2019) Growers, commodity-group representatives, pest-control advisors, university specialists, and other technical experts from the Treasure Valley in Oregon and Idaho provide an overview of onion production. They identify pest management priorities and lay a foundation for increased use of Integrated Pest Management in onions. They identify critical production aspects of this crop, and describe the biology and life cycle of onion pests. Authors organize management practices and challenges by crop life stage and describe whole-season management practices and constraints.
• (2010) IPM Insect Pests of Wheat Presentation by Steve Van Vleet, Washington State University, Whitman County Extension
• (2018) An Integrated Pest Management Strategic Plan for Treasure Valley Onions: Oregon and Idaho A newer revision exists, please see EM 9254. In a proactive effort to identify pest management priorities and increase use of Integrated Pest Management in onions, growers, commodity-group representatives, pest control advisors, university specialists, and other technical experts from the Treasure Valley in Oregon and Idaho provide an overview of onion production and discuss critical production concerns and the basics of IPM in onion production in this region. They describe each pest and its biology and life cycle. Readers will gain an understanding of whole-season management practices and constraints, as well as an analysis of management practices and challenges organized by crop life stage.
• (2017) Jumping spider encounter?
• (2017) Is it warm enough to release ladybugs?
• (2016) Internal Dry Scale and Associated Bulb Rots of Onion Onion growers and packers in the Pacific Northwest have observed a problem on red, white, and yellow cultivars: internal dry scale. Bulbs affected by internal dry scale have dead inner scales that are susceptible to fungi, bacteria, and yeasts, which can lead to rot. In addition to outlining the incidences and symptoms of internal dry scale and associated bulb rots of onion, this publication discusses the factors that contribute to it and suggests tactics for limiting it.
• (2015) Integrated Pest Management: How to Identify a Plant or Weed This video demonstrates the best ways to identify a plant or weed. It covers the process of photographing and collecting the plant and then how to narrow down and establish the plant's category. It explains how to use a field guide and a dichotomous key to identify a plant.
• (2015) Integrated Pest Management: Using A Plant Press Preserving plant specimens is the best way to identify plants by their characteristics at a later period of time. It is always best (if possible) to collect the entire plant specimen at peak production, so you have included the roots, flowers and potentially the seeds of the plant. This video explains how to properly use a plant press.
• (2015) Integrated Pest Management: Pest Management Integration This video explores Integrated Pest Management (IPM) as an approach to protecting your crop from insects, weeds and plant pathogens. IPM uses multiple tactics to manage a particular pest and takes into consideration how management of one pest may affect management of other pests.
• (2015) Integrated Pest Management: Monitoring Diseases In The Field This video explains how to do field scouting for diseases and vectors by walking through a field and observing a number of locations. Diseases can reduce the yield and nutritional quality of crops., and vectors — organisms that transmit pathogens that cause diseases — can also threaten crops. Recognizing diseases and vectors early will help you control them and minimize economic loss on a crop.
• (2015) Integrated Pest Management: Detecting Plant Diseases in the Lab This video describes how the Hermiston Agricultural Research and Extension Center examines plant disease samples to determine pathogens and plant diseases. Once the problem is identified, the lab recommends treatment and control methods.
• (2021) Potato Psyllid Vector of Zebra Chip Disease in the Pacific Northwest This publication addresses the emergent issue in the Pacific Northwest of a potato infection called zebra chip disease, vectored by the potato psyllid. Includes information on the bacterium, the biology of the vector, description of damage from both vector and non-vector psyllids, and most current research on management.
