Selected lines of Stylosanthes guianensis, S.scabra, S. capitata and S. macrocephala were established at field sites at Planaltina and Campo Grande in Brazil and at Carimagua and Caquetain Colombia. Weather conditions at each site were monitored continuously using an automatic weather station. Data on anthracnose severity caused by Colletotrichum gloeosporioides were collected by visually assessing these lines at monthly i ntervals and analysed to study disease progress on susceptible and resistant lines in relation to weather variables. Anthracnose was most severe at Planaltina, followed by Carimagua, Campo Grande and Caqueta. S.scabra cv. Fitzroy, susceptible to all Australian races of C. gloeosporioides, was not the mostsusceptible at Carimagua and Caqueta. Relation-ships between anthracnose severity and weather variables were explored using multiple regression analysis. These explained between 30 and 95% of the variation in the severity of anthracnose on Fitzroy at the 4 sites. The study highlights the need for improved under standing of anthracnose epidemiology. |

This study analyzes the effectiveness of rural credit policy to increase the adoption of ICLS. Analyzes are based on a survey with 175 farmers in the State of São Paulo, Brazil. Our estimates suggest that rural credit has positive and relevant impacts on the adoption of ICLS. In turn, the adoption of these systems may also involve investments in fixed capital and increases in operational costs, which create additional demand for rural credit. Other factors, such as access to extension policy, production scale, ex-ante perceptions, and market infrastructure also explain ICLS adoption. The access to rural credit policy is also determined by dependence on farm income, farmer?s perception of transaction costs, and supply of credit in the municipality. The study finally discusses important implications for the devising of rural credit policies and the diffusion of sustainable production systems in developing countries. |
