Author(s): GJ Goswami, LF Akbari and AR Khunt
Abstract: Coriander (Coriandrum sativam L.) is one of the most important spice crop in India. The powdery mildew disease caused by Erysiphe polygoni DC is one of the most destructive disease of coriander causing severe losses in yield. Farmers have to spray fungicides regularly for management of disease. A field trial was conducted at the Department of Plant Pathology, JAU, Junagadh to study efficacy of various fungicides for controlling powdery mildew disease of coriander caused by E. polygoni during Rabi season of 2014-15 and 2015-16. Among the different fungicides, propiconazole (0.025%) was the most effective fungicide with 11.58 per cent (two year pooled) disease intensity and highest yield 1473 kg/ha (two year pooled) followed by wettable sulphur (0.2%) with 16.14 per cent mean disease intensity and yield 1385 kg/ha. Hexaconazole, difenoconazole, dinocap and picoxystrobin were found moderately effective with 21.24, 22.90, 33.82 and 35.15 per cent disease intensity, respectively.
