Integrated control of diseases and pest of cassava (Manihot esculenta Crantz)

Autor: Lozano, J.C. Bellotti, Anthony C.

The reasons an integrated pest and disease control in cassava is justified are analyzed. Some cultural practices are listed that would lessen the problems caused by negative production factors within an ecosystem and would give high stable yields. Recommendations are given to maintain and enrich ...

The superelongation disease of cassava

Autor: Lozano, J.C. Booth, RH

A new disease of cassava has been found inducing epidemics in several cassava-growing areas of Colombia during the rainy season. The disease can be recognized by a characteristic exaggerated elongation of the internodes of young stems of infected plants and by the distortion and deformation of th...

Biocontrol of cassava pathogens: A useful approach

Autor: Lozano, J.C.

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. ...

Cassava bacterial blight (CBB)

Autor: Lozano, J.C.

The most important bacterial disease of cassava is cassava bacterial blight (CBB). This disease was first recorded in Brazil but was later reported in Colombia and observed in several other countries in South America and Africa. Symptoms of this disease are leaf spotting, wilting, dieback and gum...
