Abstract
Screen House and Field Resistance of Taro Cultivars to Taro Leaf Blight Disease (Phytophtora colocasiae)
Highlights
Taro leaf blight disease cause by Phytophtora colocasiae has become an economic disease in Cocoyam growing regions of Cameroon
The results of virulence and pathogenicity of P. colocasiae (4 isolates) on 10 improved and 4 local cultivars of taro under screen house are shown on Tables 2, 3, 4 and 5
There was variability in pathogenicity based on the small lesion lengths produced on cultivars, this included BL/SM132 and Red petiole where leaves collapse and defoliation were not observed on the 14th day
Summary
Results: The results obtained on the different taro cultivars, revealed that all the 4 isolates showed variable pathogenicity Conclusion: The results obtained on virulence and pathogenicity of Phythophthora colocasiae on the different taro cultivars revealed that all the 4 isolates showed variable pathogenicity. Taro storage roots form the basic carbohydrate element of the diet and can be eaten in many forms: roasted, boiled, fried, baked and pounded while the leaves are eaten as preferred vegetable, representing an important source of vitamins [6] These vitamins include vitamin A, vitamin B, vitamin C, folate, thiamine and riboflavin. The crop is a good source of income to its producers to the extent that some subsistence farmers generate enough revenue from taro production to take care of basic family needs [9]
