Efficacy of fungicides in in-vitro condition against Fusarium graminearum incited by head blight of wheat

Abstract

Fusarium head blight (FHB) or scab is one of the major fungal diseases of cereals worldwide. This disease can cause severe damage to many economically important crops such as wheat, barley, corn and oats. Among those Fusarium graminearum is a seed and soil borne fungus causing the head blight disease in wheat? Most of the promising wheat cultivars are under a great threat for profitable cultivation due to the attack of Fungi, bacteria, virus and nematodes. A various bio-agents, botanicals and fungicide were applied for integrated management of pathogen. So, aim of this research efficacy of fungicides in different concentration the minimum growth of mycelium was found in T4- Carbendazim (12.00mm) in all concentration at 7th DAI followed by T5 Tebuconazole (19.00, 17.00 and 16.66 mm) at 50 ppm, 100 ppm and 150ppm in T2 Azoxytrobin (38.33, 34.00 and 32.66 mm) at 50, 100 and 150ppm respectively and highest growth of mycelium was recorded the untreated control growth of 82.33 mm.
