Hello Sir
For soil borne diseases in dioscorea such as nematodes and sclerotium diseases, the site on which yam plants are to be cultivated are often recommended for soil testing for the presence of the pathogen.
Nematode can be controlled by the use of crop rotation and the use of nematicides such as carbofuran granular at the planting. Dipping of seed pieces in Nemacuron before planting also eliminate the inoculum of the pathogen from the planting materials.
Early ploughing and thorough disking which exposes the sclerotia to early germination and exhaustion before planting has also
been recommended.
Planting of yam setts with disease-free material as been found very effective in reducing nematode problems.
Yam setts are often treated with a suspension of Fernasan D or two handfull of wood ash in 4 litres of water.
Use of virus-free planting materials and meristem culture has been recommended in the case of controlling viral diseases..
Treatment of yam tubers with fungicides such as Benlate and Captan has been found to be effective in reducing fungal yam rot.
The boring beetle attack on shoot and tubers can be controlled by granular application of diazinon and carbofuran. While treatments of the yam tubers with insecticide dust (Actellic 2% Dust; ai=pirimiphos-methyl) reduces fungal infections and also ameliorate
physical damages acquired during harvest resulting in significantly fewer fungal lesions.
