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.

9 pages, via online journal, Farmers who engage in farmer participatory research (FPR) change their established social roles in households and communities. As such, comprehension of farmers’ role transitions is important to understand the extrinsic and intrinsic factors impeding or supporting the uptake and use of FPR by farmers. The existing FPR literature, however, does not address such role transitions. In this study, we analyzed farmers’ experiences with FPR and underlying role transitions in a commercial organic agriculture project in western Uganda. We drew on quantitative and qualitative data from interviews, group discussions, and observations involving farmers and extension workers. Our results suggest extrinsic and intrinsic factors affect farmers’ self-conception, influencing their willingness to participate in FPR. The level of alignment between the self-conception and the anticipated role determines farmers’ decision regarding participation in FPR and affects their response pattern. Farmers’ response pattern and individual set of inhibitors and facilitators lead to the experience of role insufficiency or role mastery, which is crucial for farmers’ continuation or termination of on-farm experiments. Understanding and facilitating role transitions is, therefore, essential for sustaining on-farm experiments, which complements current technical FPR training.
