Abstract

Experiments were conducted at Horticulture Research Station, Ooty to find the effect of new fungicide, Cyazofamid 34.5 SC + Mancozeb 64 WP on late blight disease of potato. The new fungicide mixture reduced the late blight incidence to the extent of 78.1% at 200 g/ha and was at par with the disease reduction observed (74.8%) when it was used at 1500 ml/ha. Hence, it is concluded that Cyazofamid 34.5 SC + Mancozeb 64 WP can be effectively be used for management of late blight disease in potato
