Xanthomonas wilt (XW) caused by Xanthomonas campestris pv. musacearum (Xcm) is an important constraint to banana production in East and Central Africa. The use of clean planting materials (CPM) for establishing new fields/ re-planting rouged fields/mats is recommended. However, banana is mainly p...

Parameters for the production of high-quality cassava seed are presented. The 3 aspects considered regarding the seed should be genetic (branching habit and overall vigor), physiological (seed age, nutrition, and viability, age of mother plant), and sanitary. Both systemic (fungi, bacteria, mycop...

The predominant farming system in La Colorada (Magdalena, Colombia), where cassava is a subsistence crop, is briefly reviewed. The intensive land use has caused soil leaching and infestation with root pathogens such as Diplodia manihotis and Fusarium oxysporum and cassava production has decreased...

Cassava can be propagated by true seeds and vegetative material. Obtaining true seeds is difficult and resulting plants have longer life cycles, rendering lower tuber production. Thus cuttings are preferred. Recommendations on the optimal length of cuttings vary greatly. Factors involved in using...

Recommendations are given on the var. and cultural practices used in cassava cultivation in the Colombian Llanos Orientales. Initially, soil acidity and low fertility were believed to be the major constraints; however, trials have indicated that diseases (bacterioses, superelongation, and anthrac...
