Effect of sowing dates on phytophthora blight of taro (Colocasia esculenta var. antiquorum)

The present investigation was carried out to evaluate the effect of date of sowing on per cent plant infection, per cent disease intensity, coefficient of disease index and yield attributes of taro (Colocasia esculenta var. antiquorum). The crop sown during 15th February gave highest cormel yield, despite maximum per cent plant infection, per cent disease intensity and coefficient of disease index in comparison to crop sown at 15th March, 15th April and 15th May during the Kharif 2006 and 2007 crop ping season, respectively.
