- Here we will discuss the use of dormant-season, soil-applied, pre-emergence (PRE) herbicide applications to provide residual weed control. Weeds can directly impact fruit trees via competition for water, nutrients, and light. Weeds may also affect tree growth and yield indirectly by serving as alternate hosts for insect pests and pathogens, and by providing habitat for rodents. Physically, weeds can interfere with crop management and harvest operations when they block irrigation emitters, inhibit the deposition of other pesticides, or impede the movement of workers and equipment. Successful weed management can best be achieved by employing a combination of strategies including: thoughtful site selection, proper weed identification, detailed record keeping, and by employing multiple strategies to control weeds.
- This spring, like many early season psylla controls were difficult to apply. Early season management limitations have many wondering if post-harvest is a logical time to target overwintering adults. However, currently effective post-harvest management requires area wide coordination, effective products and adequate coverage.
- Dr. Elizabeth Beers, WSU Entomology TFREC released a new webpage summarizing current knowledge on Brown Marmorated Stink Bug (BMSB) in Washington. This new page covers hosts, life stages, life history, monitoring, and management.
- A new resource: "Cherries: Botany, "Production and Uses" is out now. This title covers new scientific data on the botany, production and uses on both sweet and sour cherries. It covers the genetics, ecophysiology, production, protection and uses of cherries. Presenting up-to-date scientific data and applied information, this book is invaluable for researchers, teachers and all professionals working in the cherries value chain.
- The Pesticide Education Research Collaborative is happy to announce a new resource, “Worker Protection Standard (WPS) Respiratory Protection Guide: Requirements for Employers of Pesticide Handlers”, a 45-page guide to help employers of pesticide handlers meet the requirements of the revised 2015 Worker Protection Standard (170.507).
- Tree fruit producers and industry professionals are invited to six WSU Tree Fruit Extension Programs in Central Washington on January 12, 15, 16, 17, 18, and TBA. Co-sponsored by the Northwest Cherries, Pear Bureau Northwest, NCW Fieldmen’s Association and the Okanogan Horticultural Association, these events provide the latest research-based information on horticulture, pest and disease management. We hope you will join us to network and learn this winter.
- Join WSU for a two-day workshop on “Unmanned Aerial Systems in Agriculture” November 8-9 at WSU IAREC, Prosser, WA.
- Dates: 20-22 March 2018. Locations: Wenatchee & Prosser, Washington. The 2018 Post-harvest Fruit School is an excellent opportunity for warehouse and other professionals in the tree fruit and berry industries to deepen and develop their knowledge of post-harvest science and management with lectures, expert panels, demonstrations and tours. The speaker line-up will include regional and international experts. The meeting is being organized by WSU Extension and the Washington Tree Fruit Research Commission.
