10 pages, For some years, the Republic of Benin has promoted mechanization and modernization of its agricultural sector as a driver of food security, socio-economic development and sub-regional solidarity. New agricultural technologies such as tractors and pesticides have been introduced into the small scale farming systems and have reached record adoption rates in various agro-ecological zones of the country. However, rural actors’ use of these technologies also leads to new forms of territoriality which make some winners and others losers. This study was carried out in the cotton basin of northern Benin to scrutinize the forms of appropriation of agricultural technologies and the effects on access to productive resources and interactions between farmers and herders who are cultural neighbors. Participatory observation was carried out over ten months in the district of Gogounou where informants who were purposively selected were engaged in 164 individual interviews and 21 focus group discussions recorded by consent, transcribed and thematically analyzed. By analyzing the mechanisms of appropriation of herbicides in rural areas and the related political ecology of land use, the paper argues that herbicides reconfigure tenure systems by inducing new forms of land-tenure insecurity and land-use conflicts between socio-professional groups that depend on the same natural resources for their livelihoods. Community-based discussions can engage stakeholders in exchanges of sustainable production alternatives, just as institutional reforms are needed to better channel the uses of modern agricultural technologies.
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.
