New eOrganic Articles Posted in August

Biopesticides for Plant Disease Management in Organic Farming, by eOrganic Vegetable Disease Management Group members Meg McGrath, Gary Vallad, and Brian McSpadden Gardener. This article introduces what biopesticides are and how they can be used in certified organic production. See also Efficacy of Biochemical Biopesticides that may be used in Organic Farming and Efficacy of Microbial Biopesticides that may be used in Organic Farming for a data review of field trials with these materials.

New eOrganic Dairy Group articles include An Overview of the Access to Pasture Rule on Organic Dairy Farms, by Harriet Behar, Access to Pasture Rule: New and Revised Definitions and Finding a Pasture Stick in your area for your Organic Dairy Farm, by Debra Heleba. Stay tuned for more upcoming eOrganic Dairy Group articles, videos and Webinars relating the new National Organic Program Access to Pasture Rule and the need to calculate dry matter intake. Registration is open now for the next Pasture Rule Webinar on September 16: Maximizing Dry Matter Intake on Your Organic Dairy Pastures, by Karen Hoffman of the USDA NRCS.

The Science Behind Biodynamics, by eOrganic Soils Group member Lynne Carpenter-Boggs, is a great introduction to the topic and how the preparations are made. Lynne includes some ideas on how the preps work and how you can set up a trial on a farm to test them.

Late Blight Webinar Clips Now on YouTube

eOrganic Vegetable Disease Systems Group Members Meg McGrath and Sally Miller presented two well-attended Webinars on late blight for organic farmers and home gardeners. John McQueen of the eOrganic staff has now divided the recorded presentation into short, topical clips and uploaded them to the eOrganic YouTube channel, where we have found that they are being viewed at a much greater frequency than full length archived Webinars. Links to all the clips, as well as transcriptions of the recording can be found from the following link:

Spread the Word

bullhornIf you would like eOrganic literature to hand out at your next conference/workshop/house party, please get in touch. We have bookmarks, factsheets, brochures, and even displays you can use! Use our online form to request materials

Research-Outreach Groups (eOrganic's collaborative workspace) provides space and support for the work of organic research/outreach project groups. These groups can be lab groups, project groups (e.g. SARE and NIFA OREI projects), and even graduate courses! All group members can become members of and participate actively in groups, including farmers, agricultural professionals, students, and non-profit staff. The workspace allows groups to share files and images, make decisions (forums), and collaborate on outreach materials, proposals and manuscripts. Groups are also beginning to use eOrganic's web conferencing tools to hold virtual seminars and field tours. If you are interested in learning more about how to use to manage your group, contact John McQueen.
