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...

A new dieback disease of the forage legume Stylosanthes guianensis in South America
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...

Biodiversity, epidemiology and virulence of Colletotrichum gloeosporioides. IV. Epidemiology of Stylosanthes anthracnose at the centre of host-pathogen diversity
The degree of genetic diversity of 127 Colletotrichum gloeosporioides isolates from Stylosanthes guianensis genotypes in South America was measured at the molecular level by random amplified polymorphic DNA (RAPD) with nine arbitrary primers of 10 bases, and by restriction fragment length polymor...

Genetic diversity in South American Colletotrichum gloeosporioides isolates from Stylosanthes guianensis, a tropical forage legume
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 ...

Biodiversity, epidemiology and virulence of Colletotrichum gloeosporioides. I. Genetic and pathogenic diversity in Colletotrichum gloeosporioides isolates from Stylosanthes guianensis
Stylosanthes guianensis is a diverse tropical and subtropical forage legume of great potential. Foliar blight disease, caused by Rhizoctonia solani AG-1, can be a significant constraint to the legume’s production in some areas. The pathogen has a broad range of host plant species, and can survive...

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. Although South American isolates of C. gloeosporioides are known to be variable...
