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...

Research results obtained during 1975-87 on the biocontrol of cassava pathogens are summarized with emphasis on the use of fluorescent pseudomonads as biocontrol agents in different cassava production systems. Evidence of biocontrol of Uromyces spp. by the mycoparasite Darluca filum is reviewed. ...
CIAT`s contribution to this joint research program was (1) to develop a technique for the production of bacteria-free planting stocks of cassava and (2) to study the effect of physical therapeutic agents on vegetative material used for propagation. The propagation technique developed to produce C...

The different alternatives for disease control in cassava, reported as efficient and that could be taken into account when designing technological packages for cassava production, are summarized. These are cultu-ral control (crop rotation, planting on furrows, elimination of crop resi-dues, dista...
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...

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...
