Status of Chilli Murda Disease in Northern Karnataka and Its Management

Chilli murda complex associated with thrips, mites and a virus is one of the most serious diseases of chilli (Capsicum annuum L.) where the role of virus is poorly understood. The survey undertaken in four northern districts of Karnataka revealed in Haveri district maximum average disease incidence (45.86%) followed by Dharwad (39.36%), Belgaum (31.68%) and Gadag (30.81%). Symptomatically murda complex was noticed with severe leaf curling in both upward and downward directions with puckering, crinkling, elongated petiole and complete sterility. Dark green mottling with vein banding symptoms was also observed. Among management practices taken up, Imidacloprid 17.8 SL@ 0.3 ml/L was found effective against chilli thrips and aphids and its simultaneous application with Fenazaquin @ 2 ml/L for 3–4 sprays proved best in controlling thrips and aphids including mites together.
