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...

Cassava brown streak disease (CBSD) threatens food and economic security for smallholder farmers throughout East and Central Africa, and poses a threat to cassava production in West Africa. CBSD is caused by two whitefly-transmitted virus species: Cassava brown streak virus (CBSV) and Ugandan cas...

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...

Objective: In Southwestern Uganda, bean root rot epidemics associated with Pythium species are frequent despite the use of various management methods. This study set out to determine whether other crops in bean cropping systems of Southwestern Uganda are affected by Pythium root rots and to chara...

We conducted a survey of fungal endophytes in 582 germinated seeds belonging to 11 Colombian cultivars of the common bean (Phaseolus vulgaris). The survey yielded 394 endophytic isolates belonging to 42 taxa, as identified by sequence analysis of the ribosomal DNA internal transcribed spacer (ITS...
