The purpose of this symposium was to prepare recommendations for the Colombian Government so that they can follow a definite course of action with regard to the planning of cassava cultivation and to ensure that the technology being generated by the research institutions is transferred to the far...
A program of biological control of the cassava hornworm appears feasible. The following biological control agents have been found to reduce hornworm populations effectively: Trichogramma spp. (egg parasites), Apanteles spp. (larval parasites), Polistes spp. (larval predators) and Bacillus thuring...
A brief analysis is made of the general aspects of cassava cultivation and soil types in Mondomo, state of Cauca (Colombia). Emphasis is placed on bitter starch production, with 25 starch factories working throughout the yr. These generally operate with 2 permanent workers and are classified as s...

To help farmers identify the disease, the symptoms of witches` broom are described and illustrated. A serious disease of cassava in the state of Ceara, Brazil, it has caused yield reductions of over 60 percent. All diseased material should be burned. To control the disease, healthy planting mater...

Part of the methodology of the analysis applied to the project of the hornworm (Erinnyis ello) on cassava is presented. The project studies the hornworm life cycle and population dynamics and the economic impact on cassava production under 2 conditions (1) in cages with controlled ideal condition...

Cassava is a high-yielding crop, well adapted to areas of the tropics with low, uncertain rainfall and mean temperatures above 20 degrees Celsius.It has the ability to grow on very acid soils where few other crops will grow atall; however, highest yields are obtained under more fertile conditions...
The objectives of the agronomy program at CIAT are to increase production/ unit cost, increase and stabilize the supply of cassava available for the market, and reduce consumer prices. Three projects development of standards for efficient exptl procedures, international and national cooperative w...
Emphasis is placed on the usefulness of statistics in analyzing exptl results. Definitions are given of basic concepts and terminology. The designs most frequently used in cassava expt are completely randomized, randomized complete blocks, split plots and systematic (response surface, fan-shaped ...
