Linseed (Linum usitatissimum L.) is a member of the family Linaceae, an important oilseed crop grown in temperate and tropical zone for its seed as well as fibre, further used in the manufacture of linen. India is an important producer which contributes about 11.2 per cent to world acreage producing about 7 per cent of world production. The oil is rich (> 66 %) in linolenic acid, and is a perfect drying oil. Powdery mildew of linseed caused by Leveillula taurica (Lev.) Arn. is one of the economically important diseases that causes loss up to 60 per cent. While management of the disease, two sprays of hexaconazole (1 ml/l) and two sprays of wettable sulphur (4 g/l) at 45 and 60 DAS were found significantly superior (12% and 17.33% respectively). Similarly the plot treated with P. fluorescens (5 g/l) on 45 th day followed by hexaconazole on 60 day at 1 ml/l recorded 20 per cent disease severity.
