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. |
