Agronomic assessment of 76 accessions of tropical fine stem stylo or "tardio" (Stylosanthes guianensis Sw. var. guianensis) was carried out at the Carimagua Research Station in the eastern plains region of Colombia. Of 27 accessions tested for dry matter yield, CIAT 10136 was the highest yielder ...

Cassava (Manihot esculenta) occupies a uniquely important position as a food security crop for smallholder farmers in areas of the tropics where climate, soils, or societal stresses constrain production. Given its reliability and productivity, cassava is the most important locally produced food i...

The detection of the root-knot nematode, Meloidogyne javanica, as a pathogen of Desmodium spp. in Colombia, is the first reported case in South Aemerica. In the field, promising pasture legumes D. gyroides, D. heterocarpon and D. ovalifolium were severely damaged, while adjacent stands of Centros...

Mulching was highly effective and superior to chemical treatments for the control of web blight (WB) caused in beans by Rhizoctonia solani, the imperfect state of Thanatephorus cucumeris. Plots were established in fields with a history of repeated incidence of WB. Soilborne sclerotia and colonize...

The genetic basis of quantitative disease resistance has been studied in crops for several decades as an alternative to R gene mediated resistance. The most important disease in the potato crop is late blight, caused by the oomycete Phytophthora infestans. Quantitative disease resistance (QDR), a...

The importance, symptomatology, and etiology of the frog skin disease in cassava are briefly described. This disease has caused losses up to 90 percent or more in Quilcace, Tambo (Cauca) and other municipalities of Colombia. The 1st symptoms of the disease appear 50-60 days after planting in cutt...
