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...

The pan-tropical grass genus Brachiaria comprises about 100 species, several of which are forages of economic importance, particularly in tropical America. Acremonium implicatum is a fungus that forms an endophytic association with at least some of these economically important grasses. To ascerta...

The main insect pests and diseases associated with Brachiaria pastures are considered, with emphasis on spittlebugs, the most damaging pests in tropical America. Outbreaks of the polyphagous burrowing bugs of the genus Scaptocoris, both in Brazil and Colombia, are of concern. Other pests discusse...

Data were collected and analysed from seven field sites in Australia, Brazil and Colombia on weather conditions and the severity of anthracnose disease of the tropical pasture legume Stylosanthes scabra caused by Colletotrichum gloeosporioides. Disease severity and weather data were analysed usin...

The tropical forage legume Clitoria ternatea (L.) has important agronomic traits such as adaptation to a wide range of soil conditions and resistance to drought. It is resistant to a number of pathogens and pests. These important traits gave us reasons to look more closely at the plant. A highly ...

Acremonium implicatum is a seed-transmitted endophytic fungus that forms symbiotic associations with the economically significant tropical forage grasses, Brachiaria species. To take advantage of the endophyte's plant protective properties, we developed an efficient Agrobacterium-mediated transfo...
