7 pages, via Online journal, Hair fescue (Festuca filiformis) is a tuft-forming perennial grass that reduces yields in lowbush blueberry (Vaccinium angustifolium) fields. Nonbearing year foramsulfuron applications suppress hair fescue, but there is interest in increasing suppression through foramsulfuron use in conjunction with fall-applied herbicides. The objective of this research was to determine the main and interactive effects of fall-bearing year herbicide applications and spring-nonbearing year foramsulfuron applications on hair fescue. The experiment was a 5 × 2 factorial arrangement of fall-bearing year herbicide (none, terbacil, pronamide, glufosinate, dichlobenil) and spring-nonbearing year foramsulfuron application (0, 35 g·ha−1) arranged in a randomized complete block design at lowbush blueberry fields in Portapique and Stewiacke, Nova Scotia, Canada. Spring-nonbearing year foramsulfuron applications did not reduce total tuft density or consistently reduce flowering tuft density, flowering tuft inflorescence number, or flowering tuft seed production. Fall-bearing year pronamide applications reduced hair fescue density for the 2-year production cycle, although additional bearing year density reductions occurred when pronamide was followed by spring-nonbearing year foramsulfuron applications at Stewiacke. Fall-bearing year dichlobenil applications reduced total and flowering tuft density at each site, although reductions in flowering tuft inflorescence number and seed production were most consistent when followed by spring-nonbearing year foramsulfuron applications at Stewiacke. Suppression extended into the bearing year at each site, and dichlobenil should be examined further for hair fescue control. Fall-bearing year glufosinate applications reduced hair fescue total tuft density at each site and flowering tuft density and flowering tuft seed production at Stewiacke. Fall-bearing year glufosinate applications followed by spring-nonbearing year foramsulfuron applications also reduced nonbearing year flowering tuft inflorescence number and bearing year hair fescue seedling density at Stewiacke, indicating that this treatment may reduce hair fescue seedling recruitment at some sites. Fall-bearing year terbacil applications did not suppress hair fescue and are not recommended for hair fescue management in lowbush blueberry.

14 pages., Online via AgEconSearch., Results of surveying among 380 yam farmers indicated that farmers generally agree that use use of certified seed yam would help to improve yield because of minimum to no disease/pest infestation. Farmer educational level, experiences, access to extension services and household incomes were factors influencing farmers' perception about quality of seed yam cultivated. Authors recommended promotion of farmer education through increased access to extension services.
11 pages, Private-sector dominance of plant breeding constitutes the present norm of organic seed genetics research, which has generated concerns in the organic farming community in this era of robust intellectual property protections. Intellectual property restrictions primarily in the form of certificates, patents, and contractual arrangements are blamed for stifling the innovation of organic seed varieties. To better understand the challenges small-scale and university-based breeders and researchers face in organic corn seed genetic development, this article provides an overview of intellectual property structures surrounding seed innovation and sharing. After describing the legal landscape in which organic corn seed research and development occurs, the article details research efforts exploring the veracity of claims that contractual arrangements (in the form of seed-sharing agreements between breeders and universities) stifle the innovation of organic varieties. In doing so, the article describes the search methodology utilized and highlights a critical barrier to research: the closely guarded nature of private contracts that parties are reluctant to reveal. While we were able to identify several data points that highlighted the importance of seed-sharing agreements as a part of the intellectual property regime controlling organics research and breeding, we were unable to obtain contracts or identify disputes over contractual language to further analyze. Such contractual language only becomes available upon consent and release by individual parties to the contract or by litigation that exposes the contractual language, both of which we attempted to explore and utilize. The article concludes with a discussion of why contractual arrangements in the context of organic corn seed development are an informative piece of the intellectual property puzzle worth exploring, as well as future points of research necessary to yield data substantiating the concerns of stakeholders in the organic seed industry.

Notes:
The June 7, 2019 commentary by Barber in the New York Times was retrieved online at: https://seedfreedom.info/opinion-save-our-food-free-the-seed. It is filed with this document., Online via seedworld.com. 3 pages., Response to an opinion piece in the New York Times by celebrity chef Dan Barber. Barber reported on visiting a 24,000-acre farm in North Dakota and observing the large scale of operations. He concluded: "We should be alarmed by the current architects." In this commentary author Gale offered a differing view of the changes in plant breeding and the seed industry over the past 100-plus years - and what they mean for the future.
