A copy of the complete genome of a novel bipartite begomovirus infecting common bean (Phaseolus vulgaris L.) in Colombia was obtained by rolling-circle amplification (RCA), cloned, and sequenced. The virus is associated with leaf crumple symptoms and significant yield losses in Andean and Mesoame...

An expt. was established in Esparza (Costa Rica), on the integrated management of web blight (Thanatephorus cucumeris) in common beans under the min. tillage system. Var. Porrillo 70 (intermediate resistance) and ICA Pijao (susceptible) were used. Herbicides gliphosate and paraquat (1.0 kg/ha) of...

Silicon (Si) has been shown to suppress diseases of rice such as blast when applied to Si-deficient soils. In 1995 and 1996, Si was applied at 1,000 kg ha-1 to at two locations in eastern Colombia to determine if Si combined with reduced rates of fungicide could be used to manage leaf and neck bl...
