The effect of microwaves on the eradication of fungal and bacterial pathogens in cassava sexual seed was investigated. Healthy mature fruits were collected and dried under ambient conditions. Seeds were selected according to specific wt. by placing them in a glass of water and discarding those th...

The importance of cassava as the fourth largest source of calories in the world requires that contributions of biotechnology to improving this crop, advances and current challenges, be periodically reviewed. Plant biotechnology offers a wide range of opportunities that can help cassava become a b...

The potential of using biotechnology to improve cassava: a review
Based on research results, the advantages of cassava over other crops, the use of improved cv. for different ecosystems, good management practices, crop protection, and soil fertility requirements are discussed in detail. (CIAT)
The effects of cutting storage on cassava root and branch production as well as on other crop characteristics (wt. loss, percentage of viable cuttings, sprouting 80 days after planting, final stand, no. of seed- cuttings/plant) were studied under field conditions in the banana growing zone of San...

Data on max. and min. severity of attacks by Xanthomonas campestris pv. manihotis, Choanephora cucurbitarum, and Sphaceloma manihoticola were gathered on commercial plantations located in 4 regions of Sucre, Colombia. Regional clones Venezolana and Preta were used. In the region of Bongo, neither...

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...
