Integrated disease management (IDM) approaches for management of Alternaria blight disease in linseed (Linum usitatissimum L.) caused by Alternaria lini Dey

The management of the disease can be done through fungicides, bio-agents and plant extract but Integrated Disease Management (IDM) strategy has proved better as compare to other strategies. IDM practice also significantly increased the shoot and root length of linseed plant than untreated treatment (check). The maximum shoot (62.48 cm) and root (14.25 cm) length, seed yield (1370.70 kg/ha) and minimum disease severity (19.19% on leaves and 14.78% on buds) were recorded in treatment T4 treatment (ST with T. harzianum + two foliar sprays Propiconazole). The maximum cost: benefit ratio 1:5.26 was calculated in treatment T7,followed by 1:4.21 in T3 treatment.
