The South American forage legume Arachis pintoi was found to be affected by foliar ring spot symptoms in surveys of various localities in the Cauca Valley of Colombia. A filamentous virus (approximately 750 nm) isolated from symptomatic A. pintoi plants induced the characteristic ring spot sympto...

Cassava Frogskin Disease (CFSD) can cause severe damage to cassava roots and is one of the most important diseases of cassava in Latin America. The principal objective of this study was to identify the causal agent of CFSD. Electron microscopy, viral purifications, double-stranded RNA (dsRNA) ana...

A new disease of rice, known as ‘entorchamiento’ (crinkling), was first noticed in the Department of Meta, Colombia, in 1991. Symptoms include seedling death, foliar striping and severe plant malformation. Tissue extracts and purified preparations from diseased rice plants, contained virus-like p...

The cultivation of calopo, Calopogonium mucunoides, as a promising forage legume for the lowland tropics, was hindered by its susceptibility to a severe yellow mosaic disease observed in the Eastern Plains of Colombia. An isometric virus ca. 28 nm in diameter was observed by electron microscopy i...

A virus with filamentous particles approximately 750 nm long was isolated from African oil palm (Elaeis guineensis) with `chlorotic ring' leaf symptoms in south-western Colombia. The virus was mechanically transmitted from oil palm to brachiaria, maize, sorghum, and sugarcane (Gramineae) but not ...
