Objectives

• To survey the incidence and the spread of foliar diseases of mulberry in South India with special reference to Fusarial leaf blight.
• To isolate and identify the Fusarial species associated with leaf blight.
• To understand the importance of environmental factors in the disease development and disease spread.
• To understand the effect of disease incidence on leaf yield and leaf quality the consequential effects of rearing silkworm with diseased leaves.
• To identify suitable management practices to overcome disease caused byFusariumspecies.

Important findings

The study revealed heterogenousFusariumdistribution at varying intensity throughout Karnataka and Fusarium leaf blight was more prevalent in rainy season.

Effect of disease incidence on leaf yield revealed maximum leaf loss in MR2 variety followed by K2 and Local and its effects on rearing silkworm revealed significant loss in larval and reeling characters. Among the fungicides like Benlate (Benomil), Bavistin (Carbendazim), Blitox-50 (Copper Oxychloride), Dithane M-45 and Foltof, Bavistin is highly effective in controlling theFusariuminfection.

Application of Bavistin (Carbendazim) recommended for effective management of Fusarial disease at farmers fields.
