In vivo evaluation different doses of consortia on leaf blotch of turmeric caused by Taphrina maculans

Turmeric (Curcuma longa) is a native of Indian sub-continent and Southeast Asia. Leaf blotch of turmeric caused by Taphrina maculans is one of the destructive diseases of this crop. The field experiment of effect of different doses of consortia (Biomix) on T. maculance revealed that Maximum disease incidence and intensity was recorded in control treatment with disease incidence and intensity of 10.00 per cent and 40.00 per cent after third spray respectively. Biomix (50g/10lit) showed more disease incidence (13.33%) and intensity (34.20%), followed by dose of Biomix 75g/10lit (11.33% and 32.30%) then Biomix 100g/10lit (9.333% and 32.50%), Biomix 125g/10lit (8.00% and 26.40%) and Biomix 150g/10lit (8.67% and 22.20%). Consortia (Biomix) dose at 200 was found most effective in reducing Incidence and intensity of leaf blotch.
