The objective was to find clones of the edible aroids, chiefly tannia (Xanthosoma sagittifolium), with high levels of adaptability and tolerance to disease, particularly the tannia root rot disease. This was approached in 3 ways: 1) Clones from throughout the 5 islands were brought together for selection and maintenance in 5 germplasm collections. Three clones, 'Jabba', 'Toby' and 'Calaloo Tan ...

Post harvest fungal corm rot of dasheen (Colocasia esculenta var. esculenta) is the most severe constraint affecting its storage and export. It is first manifested as an irregular pink tinge on the corm, initiated from natural wounds, which gradually becomes blackened with pycnidia. Two fungi, Pythium spp. and Botryodiplodia spp. have been isolated from diseased corms

The acylanaline-based fungicide, Metalaxyl, is active against Domycetes and used successfully against Pythium root-rot disease of tannia. Its continuous use induces resistant strains to foliar pathogens but no record of similar activity is shown for root/soil borne pathogens. The chemical shows acropetal activity when applied to the root zone, both upwards and downwards. It is more toxic orall ...

The following field experiments were undertaken to study the production systems of aroid and arrowroot in St. Vincent and the Grenadines, Dominica, St. Lucia and Grenada: 1) intercropping of tannia with bananas and beans or plantains and melons, 2) comparison of two management systems for pure stand tannia, 3) comparison of different kinds of tannia planting material, 4) multiplication of plan ...
