Abstract:

An experiment was conducted to find out efficacy of different non-conventional chemicals to manage the early blight disease in potato. Study was carried out with seven chemicals i.e. lithium sulphate, calcium chloride, oxalic acid, salicylic acid, iron sulphate, potassium bicarbonate and ascorbic acid in in vitro condition for their conidial germination efficacy against Alternaria solani. It was observed that, oxalic acid@ 1.0 ppm concentration exhibited highest per cent inhibition of conidial germination (88.89%) over control after 24 hrs. The next best conidial germination inhibition (75.00%) was observed in case of lithium sulphate@ 1ppm concentration. This was followed by potassium bicarbonate, where 71.43% conidial germination inhibition was observed @ 1 ppm concentration. In the field condition, also the oxalic acid @ 1 ml/ lit exhibited best result in terms of percent disease incidence (32.62%), percent disease intensity (24.32%) at 73 DAP and yield of tubers (25.31 t/ha) as compared to control treatment. The overall disease reduction in case of oxalic acid was 42.10% over control which was also highest compared to all other treatments.
