A wilt and eventual dieback disease ot the forage legume Stylosanthes guianens which occurs widely in Colombia and Brazil, is described. The causal agent of the wilt disease is identified as Lasiodiplodia theobromae, a virulent, unspeciaIized, facultative, wound pathogen with worldwide distributi...

In order to contribute to improved utilisation of herbaceous legumes, in particular Centrosema macrocarpum and Stylosanthes guianensis for crop-livestock systems, the present study explored a number of management options to improve the effect of legumes on subsequent maize yield. The objectives o...

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 Caquetá in Colombia. Weather conditions at each site were monitored continuously using an automatic weather station. D...

Anthracnose, caused by Colletotrichum gloeosporioides, is the most important and widespread disease of Stylosanthes, a diverse tropical and subtropical forage legume naturally distributed in central and South America. This paper compares the genetic and pathogenic diversity of 45 isolates, which ...
